COULD THE BLACK SEA SERVE
on the basin‘s water and vice versa the Black Sea provides an excellent field for studies due to its continentality. It is the most inland ocean providing meteorological specifics. The Southern part is subtropical, the Northern part boreal. The sea surface water temperature has an average seasonal range from 4°C to 24°C, one of the highest in any sea area. In the North Atlantic the average seasonal variations hardly exceed 5°C. Mediterranean cyclones have become rarer recently but not in November, December, and February. Only the thin surface layer is basically the immediate seasonal actor although little is known about the extent to which the deeper waters may contribute to sea surface/air heat exchange. While this question might be of less importance as long as the basins water structure remains stable, it is not, once the water system is changing.
complex state of the living resources and recent changes is a subject
far too big for this paper. But as a core issue of concern some few
notes shall be made. It seems that the
Black Sea was less a fishing reserve than one could have expected. In
the almost 20 times smaller and only 8.5m (max.14m) deep Azov Sea the
fish catch exceeded the total landings from the Black Sea well after
World War II. In the 1930s the best Azov Sea catch year
amounted to over 304,000 tons and over the period from
1930‑1990 to an average of 171,000 tons/p.a. but have shrunk to yields of a mere 8‑35.000 tons recently. In 1988 Menemiopsis began invading the Azov
In the Black Sea the annual catch was just above 100,000 tons between1940 and 1960 but increased to 650,000 tons/p.a. around 1990. But the picture is not uniform, e.g. Bulgarian catch decreased from more than 19,000 tons in 1981 to 2,000 tons in 1990. With the outbreak of Mnemiopsis the traditional harvest of Black Sea species dropped to a small fraction. The distinct harvest differences before the 1980's raises the question on the role of the anoxic water mass or, to address it in more in a legal sense: what status of environment is to be protected and preserved and what is the basis to assess changes and damage. While fishing has increased strongly everywhere since the 1950s the small Black Sea catches compared to the Azov Sea are somewhat surprising even if dolphins took a share until recently. The catch in the Baltic was up to 1 million tons in the 1970s. The fishing industry in Russia and other former East‑Bloc countries was known for their efficiency. Brackish water can easily sustain a high fish population, but fish do not always adapt easily to changes in salinity. According to Volovik et al., long term observations in the Sea of Azov indicate that the salinity plays a big part in the Azov Sea fish population. While the fish is gone the biomass of the invaders have been estimated as being as high as one billion tons for the Black Sea and several tens of million tons in the Sea of Azov.
One of the most interesting questions relates to the meaning of the common notion that the basin is a 'quasi‑steady state system‘, or to reduce the question to a single issue: how thick was the oxic sea surface previously, e.g. 500, 100 & 50 years ago, did it thin gradually, did it vary periodically, did the deep water body ever reach the surface since Mediterranean water poured into the basin about 8000 years ago or, finally, could that happen in the not too distant future? Recent observations indicate that surface water salinity has increased in the NW self region and water transparency decreased during thelast decades. Still under discussion is whether the total basin‘s upper layer of 200 m has changed in regard to salinity and temperature recently.
the basin are unpredictable. But raising a brief scenario may round up
the basin feature a little more. To start with, the question previously
raised whether the anoxic hydrogen sulphide deep water ever reached the
surface. It is unlikely that this has ever happened. It should be
known. Hydrogen sulphide stinks like rotten eggs. Once the saltier deep
water mass comes to the sea surface, vertical deep convection could
start due to cooling of the top layer. The Black Sea could turn into a ventilated basin as the Mediterranean and as
other seas are. But this is theoretical speculation, at least as long
the positive fresh‑water balance is maintained.
Less speculative is the occurrence of earthquakes with seismically generated tsunamis waves crossing the Black Sea. Four tsunamis with heights of less than 0.53 m have been recorded this century, but historical events reached heights of 4m. Unfortunately, little if anything is known of the seismical affect on the sea surface layer or, vice versa, on the deep water body. It might be very significant, at least temporarily. The deformation of the bottom topography in the September 1927 earthquake near Yalta was documented, the emergence of a large break in the sea floor, the sliding of silt down of the Crimean underwater mountains.
Black Sea is special on its own account but in addition its
continentality makes it particularly sensitive to man‑introduced
processes. In terms of sustained marine environment it is the first large water body which could 'collapse',
whereby collapse is defined as irreparable or irreversible. While the
present catastrophic state of the marine biosphere is anthropogenic, it
cannot be ignored that the basin's natural composition contains a sort
of environmental stress uncommon in other oceanic basin.
In this respect it is unique. That might raise the thought for not considering the Black Sea as a model case as too 'exotic'. One can emphasize that there is a great need for socioeconomic indicators for unwelcome alterations to the marine environment, the particularly poor state of the Black Sea or its ideal size and unique environment for carrying out synoptic investigations on oceanographic phenomena that are common to different areas of the world oceans. The pros and contras could fill many pages. The Black Sea would end up as the most suitable "miniature ocean".
is what every one asks for when no one knows what to do. Meanwhile the
marine environment is governed by numerous conventions and regulations.
But the state of coastal and enclosed seas is deteriorating. It
shouldn’t. Law can be the most programmatic and decisive management
tool if based on sound knowledge, long term strategy, a comprehensive
programme, enough means and disciplined execution. Lack of knowledge is
the core deficiency, litigation can not close such gap.
The present legal approach concentrates on pollution prevention. The strategy is correct. If any human impact or polluting the sea were stopped, the problem would go away. Unfortunately, the problem is not that simple and this is being realized more and more. This awareness is reflected in the terms "precautionary principle" and "sustainable development" widely referred to in the Rio Declaration 1992 and Agenda 21. The marine environment issue requires acknowledgment of the fact that man will never be able to leave the seas 'to themselves' again, as well as the condition, that the sea is a object of 'its own rules'. Management must be based on the knowledge of these 'rules' and the impact of man‘s inevitable ongoing 'sea activities'. Marine management today lacks not only the means on which to formulate a strategy of 'balanced interest' between the rules of the seas and marine activities, but also the time to wait for establishing the facts on which decisions must be based. The oceans are too big to understand them soon. Based on these preliminaries and the previous chapters the present marine environment management approach by emphasizing the Black Sea situation are briefly introduced below.
Black Sea Pollution Convention (BSPC) represents a minimum set of legal
framework but addresses all main aspects as required in Part XII of
Art. 6 BSPC, hazardous substances and matter ;
Art. 7 BSPC , land‑based sources;
Art. 8 BSPC, vessels ;
Art. 9 BSPC, cooperation in combating pollution in emergency;
Art.10 BSPC, dumping;
Art.11 BSPC, activities on the continental shelf;
Art.12 BSPC, from or through the atmosphere;
Art.13 BSPC marine living resources;
Art.14 BSPC, hazardous water in
But it is still less detailed than regional conventions recently redrafted or amended, e.g. the North‑East Atlantic Convention, 1992 (NEAPC) and the Baltic Sea Convention. Like other treaties, the BSPC is conservative in its approach to national sovereignty. The functioning of the established "Commission on the Protection of the Black Sea against Pollution" is bound by unanimous decisions and recommendations.
In essence, pollution means the introduction of substance or energy by man which have or may harm/hinder/impair/reduce marine life, human health, marine activities, quality for use of sea water, and human amenities. The BSPC definition corresponds with UNCLOS. The meaning of marine pollution can be limited to two conditions: introduction of something by man and a reciprocating affect in some kind to man. Definitions on 'harmful substances' extend the meaning of pollution on the affect on biological processes. The BSPC follows this approach.
17 of Agenda 21 provides as a key objective "integrated management and
sustainable development". The preamble of NEAPC refers to "sustainable
management" describing it as "management of human activities in such a
manner that the marine ecosystem will continue to sustain the
legitimate uses of the sea and will continue to meet the needs of
present and future generations". The "sustainable management" clearly
indicates the direction, sustaining the uses of the sea for the need of
man. The Odessa Declaration 1993
referce to 'Integrated Coastal Zone Management' by requiring "to
elaborate and implement national coastal zone management policies,
including legislative measures and economic instruments, in order to
ensure the sustainable development in the spirit of Agenda 21".
Chapter 17 of Agenda 21 states that "a precautionary and anticipatory rather than a reactive approach is necessary to prevent the degradation of the marine environment". Considering the notion of its own it might result in far reaching consequences, as too little is understood of changes and interactions within the ocean system. Actually, the introduction of the precautionary principle is part of the concept for "Integrated Management" requiring the adoption of precautionary measures, environmental impact assessment, clean production techniques, recycling and other activities. In this respect it is meant as a program but does not necessarily imply a diversion from presently applied principles and strategies. However, the recently adopted NEAPC stipulates as preventive measure "even when there is no conclusive evidence of a causal relationship between the inputs and the effects" . BSPC does not have a corresponding provision but requires nations to communicate their findings to the Commission before they commence activities which may cause substantial pollution or changes to the marine environment.
The polluter‑pays principle has been included in recent treaties, e.g. NEAPC and Baltic Sea Conv.. The BSPC is only programmatic in this respect, obliging the parties to adopt individual rules and regulations on liability for damage in accordance with international law. Until now the principle has had little effect. While few separate or significant cases and incidents are taken up, the bulk of ocean pollution from land and through the air passes without any redress. Neither the legal term pollution can be applied nor the ‘damage‘ to the oceans assessed.
summarizes a number of topics in Art. 15 para.1‑7 covering the scope of
other related recent treaties. They are programmatic in their content
and describe priorities and management concepts as outlined in Chapter
17 of Agenda 21. To this end, the Black
Sea Commission plays an important role for implementing the concept, as
the State Parties are required to cooperate through the Commission in
establishing appropriate scientific criteria for the formulation and
elaboration of rules, standards and recommended practice and procedures. The programmatic
Complementary or joint scientific and technical research is to establish and exchange relevant scientific data and information . It includes designated competent national authorities responsible for scientific activities and monitoring.
of the quality of the marine environment is a principle requirement but
not used uniformly. The BSPC concept includes a number of aims by
requiring the development of ways and means "for the assessment of the
nature and extent of pollution and the effect" including risk
assessment, while, for example, NEAPC concentrates on assessment
including the evaluation of measures taken, planned and priorities.
Best available technique is a fundamental obligation in modern environment legislation. BSPC in this respect only requires cooperation in the development, acquisition and introduction of clean and low‑waste technology.
Best environment practice is a corresponding strategy, actually depending on a process of balancing, e.g. hazard versus social/economic implication. Here as well, BSPC does not formulate it as a principle to be applied but requires cooperation for finding remedies or less harmful methods.
The bodies concerned with the implementation of BSPC are meetings of the Contracting Parties and the Commission. Non‑Black Sea States which accede upon invitation by all Contracting Parties may act in an advisory capacity. Interna tional Organizations can be invited to assist in determining measures to be taken. In the 1993 Odessa Declaration the responsible ministers adopted objectives and priorities and agreed on meetings on a triennial basis to review progress and implementation. Decisions to be taken by them, are to be consistent and integrated with the implementation of the BSPC.
legal framework for the Black Sea is consistent with internationally
applied concepts and strategies for the protection of the marine
environment. That the concept is more general than related treaties
with a history of up to three decades need not necessarily be an
disadvantage. Actually, if all regional marine environment treaties
were applied to the extent required, neither the Black
Sea riparian countries nor other coastal states would have to bother
about the marine environment. To this extent, the legal framework seems
sufficient but unfortunately it is not. As far as it serves as
programme it still is far short of a concept to regard the oceans as an
object "in their own right" which are to be protected and
preserved (Art.192 UNCLOS).
If law is to serve as an instrument to enforce an obligation,
management skill and reliable facts are required. Only a generation
ago, a marine scientist described the oceans as " the great matrix that
man can hardly sully and cannot appreciately despoil".
this scientist must have been one of the last fellows of his time to
regard the seas invulnerable, in a nutshell, the legal concept is from
that time as well. Only the effect on man was the concern, the ocean
system itself was still taken for granted. While the strategy changes
toward more regard to the sea itself, the question is time. How long
will it take to understand the ocean system sufficiently, and how much
time is left for successful ocean management. Not more laws but laws
based on knowledge may achieve what it is they are supposed to achieve.
That the Black Sea needs a sufficient observing system is stating the obvious. It is possibly more urgent than everywhere else. A test site would greatly assist but a model case has to embrace more general aims.
subject of this Chapter is to discuss the relationship between the
required input by an ocean observing system and the point computer
modeling can prove being capable to
provide actual ‘true ocean images‘ and reliable forecasts in regard to
sea temperature, salinity and currents. The
investigation is to evaluate reasons whether the Black Sea could be a
convincing test field for progress in ocean observing and computer
modeling. In this respect three different tasks can be addressed in the
1. The thin surface layer ( depth < 200m) in regard to oceanography,
weather and climatic changes.
2. The cold intermediate layer (CIL) between the surface layer and
deep‑water on interchanges between two ocean water bodies.
3. The deep‑water on ocean circulation and impact by water in‑flow
through the Bosporos, weather/climatic forcing, tsunamis and so on.
The aim at least is simple. How big or small must an observation system be to provide models with data and to test the quality of oceanographic and atmospheric computer models in comparison to natural processes. Computer versus nature. If models fail to meet the required targets, there is no chance to model other oceans. If modeling partially succeeds, the limits of models or the extent of usefulness can be better understood. If the test proves the value of computer models very high efforts will still be necessary to transfer, improve and apply them in large seas and the open ocean.
principle aim for collecting more data from the oceans and organizing
distribution is to run 'models'. Meteorology led the field. The concern on
climate changes increased the interest for modeling. The First World
Climate Change Conference in 1979 asked for more ocean data to discover
"to what extent climate is predictable" and the Second Conference in
1989 approved a Global Climate Observing System, to be organized by the
World Meteorology Organization (WMO). Subsequently the Earth Summit 1992 emphasized
the need for a complementary ocean observing system as follows:
order to determine the role of the oceans and all seas in driving
global systems and to predict natural and human‑induced changes in
marine and coastal environments, the mechanisms to collect, synthesize
and disseminate information from research and systematic observation
activities need to be restructured and reinforced considerably",While recommending:
States should consider:"Supporting the role of the IOC in cooperation
with WMO, UNEP and other international organizations in the collection,
analysis and distribution of data and information
from the oceans and all seas, including as appropriate, through the
Global Ocean Observing System (GOOS) special attention to the need for
IOC to develop fully the strategy for providing training and technical
assistance for developing countries through its Training, Education and
Mutual Assistance programme." 
on appeal the Intergovernmental Oceanographic Commission (IOC) went
into action on GOOS (see Chapter I). The objectives are: to produce description and prediction
of the state of the world oceans; to encourage national governments to
finance, or at least support planning and developing an ocean observing
system, and to help governments to identify observational programs, and
local and regional models and data products.
has become common in science. It aims not only completing a "snapshot"
of the oceans and weather at a given time, it also to open a picture
into the future. Actually, the concept of GOOS
is data processing, modeling and computer science. Computer numerical
simulation drives plots, contured fields and provides useful
interpretations of the data from the internal structures and processes
in the ocean on a 10‑100 km scale, thus identifying rotating eddies,
meandering, current, fronts, and overlying water masses of different
density. The rapid evolution of computer
technology guarantees the concept of GOOS outlines, that by the end of
the decade computer will be able to make the computations needed, many
multiples of one million calculations pre second (teraflops). GOOS
produces the raw data, and model outputs, for forecasts, analyses, and
design criteria to provide:
– Global scale products delivered operationally and
electronically to model centers for
assimilation into ocean basin scale models, or global ocean‑atmosphere
– Global basin scale products delivered to regional or local modeling groups, to be combined with higher resolution data application.
GOOS is regarded as a principal tool for improving forecasting oceanographic processes and enhancing atmospheric and climate change computer modeling. Regional programs are structured to meet this end. "The Strategy for EuroGOOS", prepared by an informal regional association of European agencies, defines operational oceanography as activity of routinely, disseminating, and interpreting measurements of the seas and the oceans and atmosphere so as to:
– provide continuous forecasts of the future condition of the sea for as far ahead as possible,
– provide the most usefully accurate description of the present state of the sea including living recourses,
– assemble long term climatic data set which will provide data from description of past states, and time series showing trends and changes.
EuroGOOS aims "to run an ocean model with a resolution equivalent to that of an atmospheric weather forecasting model requires a computer a thousand times more powerful." EuroGOOS members recently decided that it is logical for Europe to concentrate resources on the Atlantic (EuroGOOS Global Pilot Project).Although well aware that "huge areas of the internal ocean are 'data‑ free'" and many more real data are required, the trust in modeling is nevertheless immense.
International Workshop on the Black Sea in
Varna 1991 indicated a variety of topics to be
investigated and monitored, i.e. "to establish definitive phenomenology
for salinity, temperature, O2 and H2S structures,
transport and dispersal characteristics, as well as suspended sediment
distribution". It addressed modeling and the fields the riparian
countries are sufficiently equipped to work.
It recognizes the Black Sea as one of the ideal basins of the world
ocean to study long term variability and climate changes in the sea
level, the major elements of the atmospheric forcing, the components of
the water balance and the hydrographic characteristics together with
the implications on various biochemical processes.
The subsequent "Workshop on Regional Black Sea Co‑operation in Marine Research and Systematic Observation" in Varna 1994 proposed:
– The Black Sea Observation and Prediction Research Project: the initiation of a regional Black Sea GOOS (PP1) and,
– Dispersion of sedimentary material in the Black Sea and its evolution in the recent geological history of the basin (PP2),
At the IOC Black Sea Programme meeting in June 1995 the project was endorsed as initial tasks for 1996‑1997 and after review by the Black Sea Regional Committee adopted by the Executive Council of IOC in 1996 as work program for 1996‑1997.
Black Sea GOOS concept is titled: " A Step Toward Observation and
Prediction System" and outlined, inter
alia, as follows:
1. Region: Black Sea.
2. Participants: Bulgaria, Georgia, Romenia, Russian Federation, Turkey, Ukraine.
3. Duration: 2 years.
4. Overall project goal: to improve regional capabilities inoperational oceanography including observational, predictive and services aspects of multidisciplinary application.
5. Specific project objectives: to implement basic elements of operational network for observation, oceanographic data exchange, assimilation, forecasting, and issue of products for marine and ecologicial application; to develop science plan for the Black Sea GOOS programme further development.
6. Background (shortened): In general, the region has considerable expertise and scientific potential to gain benefits from participation in GOOS. Nevertheless, there are some obstacles for the development of operational oceanography, which are connected to the following lack of open sea observations, long‑time series of basic elements, unified methodology and standerized equipment for oceanographic observations, insufficient and in‑effective data exchange between national observational networks.
7. Pilot project activities (shortened) Inventory development of existing national observational networks, data processing and predictive tools, models, and review of their scope and capabilities (..). Restoration of (at least) minimal required open sea real‑time or near real‑time observational system (not less than one vessel for each participating country reporting in the SHIP code). Restoration of BATHY/TESAC observations in the Black Sea. Use of off‑shore platforms for marine observations.
8. Pilot project strategy: Compliance with regional strategy for GOOS development. Use of experience of EuroGOOS, NEARGOOS and other existing oceanographic and environmental programmes.
is the main driving force of the weather and climate. The atmosphere
holds less than one thousands part of the ocean water masses. For each
kilogram of water on Earth, only one
milligram is stored as soil moisture. 22,000 weather observations and
analyses have been made twice a day over the last decades. The by far
greatest project to collect data from the oceans, the costly World
Ocean Circulation Experiment (WOCE)
is to make 23,000 stations over the time period from 1990‑1997, roughly
the same number of stations collected prior to 1990. The WOCE provides
8 stations per day over the project period. It would be easy to go on
with superlatives, simply because the average depth of the oceans is
roughly 3500m containing 98% of all water available on Earth.
If one considers it to be necessary to observe
the formation and movements of atmospheric moisture around the world
for weather forecasting every day 44,000 times, a system which has one
thousand times more water may, theoretically, require 44 million
pieces of data daily to reach the state of art in meteorology and
climate research. Or, if one considers for every
200 square km and at every 500 m of water depth one unit for
measurement, a calculation would drive the number of stations as high
as 10 million. But it is not only a question of number and distribution
of stations but particularly in what frequency real data need to be
obtained per day, week or month according to complexity or stability
of a sea area or at a certain sea level. While the upper level of the
sea would need a firmer observing network, in depths of more than 200m
the number could be less. On the other hand, ocean observation is not a
subject for climate research alone, but a detailed picture of all
ocean waters is a necessary tool to detect anthropogenic forcing. But
today any given number of data sufficient for modeling or providing a
true actual description, sufficient enough for longer forecasts is
mere speculation. The former may require many hundred millions per week
while the latter could prove impossible
except for mere indications of possible general trends regardless how
much real data is collected and how big the computing capacity employed
Whatever the number of ‘real data‘ or stations a reliable global ocean observing system is needed. Due to its size, a Black Sea observing system would could be one thousand times smaller. Actually, it should require much less, as more than 90% is in a ‘quasi‑steady state‘ with a water renewal time of about 450 years. Thus the anoxic deep‑water with an almost constant level of temperature (8.9°C) and salinity (22.3‰) works like a huge magnifying glass. Nevertheless, the deep‑water is not free of external forcing ( e.g. inflow via Bosphorus) and may prove more difficult to model than possible to imagine today. The water flows, neither every of it part with the samespeed, nor necessarily in homogenous directions, and a current of one centimeter per second is more than 300 km per year. The deep basin currents is often much faster. On the other hand, the surface layer together with the boundary layer (CIL) may even require more data collecting means and modeling capacity as an open ocean area of the same size. The upper sea‑surface layer of about 100m is the most important for seasonal weather. That is particularly the case with regard to the Black Sea where sea‑surface temperature differences between summer and winter are the greatest of any ocean area.
aim should be to find a balance between the volume of ‘real time data‘
by observations at a given time and space to imposition ocean/climate
models to produce an ‘ocean image‘. For this purpose modeling is here
divided in three principle tasks:
Firstly: Implementation of data into a computer ‘ ocean image‘ according to place and time (data management).
Secondly: Producing an actual true ‘ocean image‘ frequently (e.g. every day) based on observed data, whereby an insufficient number of ‘real time‘ observations is replenished by computer modeling, but sufficient enough to identify the cause of past and recent changes, natural or anthropogenic
Forecasting ocean processes over a long
period of time.
After all, computer modeling will have to play an important part in understanding the natural common interactions and processes. Computers with many teraflops will provide many interesting oceanic and atmospheric images and will allow intentional forcing by the law of physics. The question is how far it reflects reality and even more, how long it will take to prove a degree of reliability to rectify decisions been based on computed results. Many hundred millions of dollars are spent annually on refining simulation models. To this end, GOOS is designed to improve the increase and flow of data to modeling centers. It may work one day, in 20, 30 or 50 years. Until then there is no proof of whether all the investments have made sense, but in particularly there are many immediate problems to solve and many important decision must be made. Modeling the oceans and climate based on GOOS should be given a chance and forced to prove reliability.
It is not witching the scope of this paper to discuss the wide variety of observing means available, satellite, acoustic thermometry, anchored and drifting buoys, vehicle and robotic devices, merchant ship sensoring, etc.. Most are designed for specific or multi‑ purposes on a wide range. For example, the commercial Seawatch buoy is equipped to collect: air pressure, air temperature, wind speed and direction, wave parameters, sea currents, vertical temperature and salinity profile, oxygen saturation, nutrient contents, particle or algae concentration and radioactivity, while a global system of 500‑buoys could cost some $ 100 million p.a. But a description of the actual ocean processes and impact on climatic changes requires access to data from the ocean depth in yet unknown number. Temperature and salinity is not only the major force of ocean dynamics and ocean water determine the regional and global weather and climates. Actually, a cheap and reliable device to measure sea‑temperature, salinity and currents at any ocean space or depth frequently and accessible by data transmission or data collection within a reasonable time is not available. A test program in the Black Sea would not only offer the opportunity for comparing available measuring technology but include the development of specific technology necessary and economically feasible for mass employment in the open ocean basin. Due to the status of the deep water and the close distances to harbors the task would be easier to achieve than in larger basins with faster currents and more complex conditions.
The following concept is meant only as an example to indicate the aspects. Other approaches could well serve a test equally or even much better. The task could be defined as follows:
testing the reliability of computer models create a competitive
situation between a unit working with the latest computer
technology(CU) and a operational unit (OU) assigned to run a
comprehensive observation system to collect data of sea temperature,
salinity and currents in the Black Sea basin with
the option of subdivisions in CU and OU with regard to the basin‘s
water bodies and the cold intermidiate
layer (CIL), on the following condition:
(1) The task of OU is to organize an 100% correct actual ocean description/image and forecast on a defined small scale up to seven days through observation (real time data) and modeling. The task is confined to a time limit (test period), e.g. 2, 4 or 10 years. The number of observing stations to be employed and placed derives from the task and time limit.
small scale resolution could for example be defined as: a space by 100
m x 100 m in square and 10 m per depth from the sea surface to the CIL ( about 150 m depth) and
with a larger scale in the deeper water (e.g. 500 x 500 x 500 m).
(2) The task of the CU is to predict oceanographic and atmospheric processes well in advance of a week, at least up to a year or longer. For this purpose they use all available data from OU and other sources.
(3) After OU has proved the installation of a 100% correct forecasting system for up to max. seven days the CU should prove within a given number of years, that models are reliable or to what extent.
The test could be declared as positive once the CU is capable of providing a correct oceanographic forecasts for two years in principle on the space scale the OU had to work.
difficult and expensive such a test could turn out is impossible to say
but it would save billions and time in pursuit of a reliable global
observing system. For the first time a baseline for many academic,
practical and legal questions would exist, whether for political
decisions, ocean management or anthropogenic impact assessment. But
foremost a Black Sea test could indicate the parameters required for
monitoring the biggest physical system of the global natural commons
and interchanges within the global system.
up a data providing system in the
deep‑water seems foremost a question of measurement technology followed
by the number required. If it would depend only for providing
resolution of general internal oceanic processes like rotating eddies,
currents and fronts (ocean climatology) the number could possibly a few
hundred. But as the ‘quasi stable state‘ of the deep‑water is
nevertheless subject to external forcing the number of devices required
could turn out to several thousands. If two thousand devices are
employed, each would have to ‘cover‘ the volume of 240 km3,
which is roughly two hundred times larger as the scale suggesed
(500x500x500m) as task for OU. This part of the observing system will
in particularly have to show that it can not only contour the permanent
inflow and spreading of Mediterranean water into the basin and the
heating at the sea‑floor detailed enough, but also the processes and
changes incurred by earthquakes and tsunamis. It is known that about 80
earthquakes and half a dozen tsunamis within the Crimea‑Black Sea region occurred. OU will be
possibly faced with a number of other question as well, such as the
volume of the deep‑water.
The CIL is certainly a particular challenge in regard to observing technology, density of devices, frequency of data transmission. While the CIL is formed on the NW continental shelf a comprehensive image of the boundary between the ‘flowing‘ overlying water masses over the deep‑water is crucial for oceanographic processes and the first major baseline for ocean‑ atmospheric modeling. From the CIL to the surface the water layer is subject to vertical convection. For this part of the sea the data could come from different observational means when initiating a test programme. But either part, observing or modeling by OU is likely to be realized soon that the goal for providing actual ‘true images‘ and forecasts up to seven day, can not be met.
In this case the rapid installation of
additional devices is paramount. At least, at this point reliable and
cheap instruments (mass production) should be at hand. Alone for the
surface layer of about 100m depth the number required could go into
thousands. If only four units, one per 25 depth in a sea area of 20x20
km are employed, the Black Sea would have to have 1600 units. This part
of the programme, sufficient number of measurement devices, would play
a very crucial aspect for corresponding observations in the open
oceans. Any investment and effort in this respect would determine
subsequent investment in the other 99.9 % of the oceans. For this end
the quality of observations and short term modeling by OU should ensure
that the required number of devices are brought into service without
delay and if deemed necessary the number must be raised to many
After all, the task of the Computer Unit (CU) needs the best possible data input as soon as possible. It should have no reason for excuses in this respect. The type of computer models and their forecasting aims should be defined at the beginning of the test phase, but in the conceptual approach the CU should be free to achieve the goal, forecasting as "far ahead as possible" (EuroGOOS), at least with reasonable results e.g. two years in advance. In addition CU work should show the reliable fields and flaws of modeling the oceans and the extent of usefulness in climatic change research.
The Black Sea is the only ocean for running a reasonable comprehensive test‑ site on ocean dynamics and processes. Its feature is oceanic with two unique water bodies for synoptic investigations. By developing the technic and experience of ocean observing in a small‑scale laboratory like environment will not only prevent misinvestments but may significantly reduce the risk of finding out in the future what should and could have been done. To ensure that it does not come too late it is necessary to establish a reliable relationship between ‘real data‘ required for sufficient computer models and whether or to what extent computer can preplay and predict the future processes and implication for man of the natural commons. The Black Sea as a model case can only provide an initial step, while subsequent systems in the open oceans will still remain a magnitude challenge. Establishing a true ocean image and corresponding models within the confines of the Black Sea is likely to be many tens of thousands times easier than in the Atlantic. But significant achievements in a laboratory like environment in this respect would not only enhance new approaches in preventive and precautionary ocean management but form a rich source for scientific and legal work on understanding and managing the marine environment. In particularly in the field of anthropogenic impact on ocean processes a comprehensive search of standards and rules on assessment and compensation could be undertaken.
Developments on environmental assessment and compensation was raised by the Rio Declaration 1992. In the marine field it is unlikely to happen soon and sufficiently. A rule finding mission is foremost a matter of collecting, comparing and evaluating facts while any subsequently rule drafting deepens on political directives and mere craftsmanship. Gathering ocean related facts more often than not quickly turns bottomless. The functioning of the seas as well as its natural changing habits on one hand and the oceans reaction to a global industrialized society on the other hand is little understood. Implementing a test‑site on ocean observation and modeling (Model I) would form for the first time a principal baseline on the most important aspects of the oceans, ocean dynamics in a ocean basin. Investigating anthropogenic forcing comprehensively would be given a good chance for advancement in ocean management.
The functioning of civil societies rests
ultimately on responsibility. Article 192 UNCLOS implies the scope of
responsibility of States:
protection and preservation of the oceans. Thus a pre‑condition is the
assessment of antrophogenic forcing of changes. The laws have to define
ocean management reactions once impacts or changes in the marine
environment have been established. This includes to stipulate monetary
charge or taxes and punitive measures. Until now the laws concentrate
on damage compensation for economic loss in a narrow band. The approach
is conservative in so far as it is based on legal possession, ownership
and financial losses. The most advanced international framework in this
respect can be found in the field if shipping, particularly in oil and
hazardous goods transport. Other sources of impact on the marine
environment, e.g. from land‑based sources, are still poorly addressed.
1972 the UN Stockholm Conference on the Human Environment in a
Declaration (Stockholm Declaration)
required States not to cause da@''fbeyond national jurisdiction. The
Parties to the 1974 Helsinki (Baltic Sea) Convention enthusiastically
agreed "to undertake, as soon as possible, jointly to develop and
accept rules concerning responsibility for damage". It has not happened
but the subsequent Baltic Sea Convention from 1992
(Art.25) deleted the phrase " as soon as possible". This
case stands not alone. In marine field little to nothing has been
achieved. The primary reason is not political indifference
but the insufficiency of information available due to lack of means to
establish facts. The facts on ocean physics and dynamics become fully
accessible only by a combination of comprehensive observational means,
assessment capability and by thorough interpretation
of observational findings. The oceans are by far the least accessible
natural system on Earth for developing guiding principles of ‘balance‘ between man and the oceans.
the Contracting Parties to BSPC are committed to adopt national rules
and regulations on liability for damaged caused to the marine
environment of the Black Sea.
The problem they face is not a regional but a general one. The
international law has little practical
guidance to offer. The stalemate in this respect does not only hinder
the evolution of rules and shared responsibility for the ocean but
neglects the role a uniform law concept can and should play. Marine
environmental law has to address all aspects as assessment,
responsibility, compensation and liability comprehensively, but has to
be correspondingly clear, fair, and just
to every one and for every one.
The Black Sea as a 'miniature ocean' in which the water body is almost completely on its own, circulating for many years within the confines of the basin, could be used to reverse the stagnant situation illustrated by reference to the Stockholm Declaration requirements a quarter century ago.
Assessement means to fix or decide the value, the amount, the state of something, the value of property, the amount of income for a tax , fine or other payment, the state of the environment or the objective is: "Identification and assessment of problems". The extent
the meaning of environmental assessment if used in legal documents is
often only implicitly given by the aim of legislation. In general the
term indicates a plain description of a status quo but in
regard to the environment implies to evaluate the assessed status against either the status in the past or in the
future. This is often indicated by the word "impact". The Convention on
Environment Impact Assessment in a Transboundary Context, 1991 provides two
definitions in this respect for proposed activities:
impact assessment" means a national procedure for evaluating the likely
impact of a proposed activity on the environment", and "Impact" means
any effect caused by a proposed activity on the environment including
human health and safety, flora, fauna, soil, air, water, climate,
landscape and historical monument or physical structure or the
interaction among these factors; it also includes effects on cultural
heritage or socio‑economic conditions resulting from alterations to
In more general terms environmental impact assessment can be defined as every alteration of the physical, chemical or biological properties of the environment caused by any form of anthropogenic matter and energy or any other human activities which affect it in a direct or indirect way, investigation includes the comparison between past and present or present and future. While this may work fairly well for land sites and along beaches the situation is very different in ocean waters.
differentiates between at-sea assessment and precautionary assessment. Article 204 requires
to observe, measure, evaluate and analyse the risks and effects of
pollution. Article 206 is concerned with planned activities. According
assessment should be directed by collecting the following information:
(1) Climatology, (2) Terrestrial geology, (3) Marine geology, (4)
Marine and coastal hydrography and physio‑chemical characteristics, (5) Biology, (6) Human values and uses. These
criteria are based on the aim to evaluate the abilityof
an environment to accommodate a particular type and level of activity
(incident) without unacceptable consequences, called "environmental
capacity" or ocean's assimilative capacit
BSPC requires the signatories, inter alia, to conduct studies with the
aim to develop ways and means for the assessment of the nature and
extent of pollution and of its effect on the ecological system, to
examine and to assess risks and to cooperate. The scope is pollution
related as defined by both conventions simultaneously. More detailed target
have been set by the Odessa Declaration 1993 on listed substances, a
trend monitoring system and provisions on assessment and monitoring. The Declaration
states: " To introduce compulsory environmental impact assessment of
all projects in the private and public sector according to national
criteria, which will be harmonized by 1997 where possible"
The Baltic Sea Convention uses the term in regard to proposed activities with possible transboundary impacts and requires that measurements and calculations of emissions from point sources to water and air and inputs from diffuse sources to water and air carried out in a scientifically appropriate manner in order to assess the state of the marine environment of the Baltic Area and is more specific in regard to pollution to land‑based sources. The NEAPC requires the assessment of the quality of the marine environment in accordance with the Annex IV to the Convention including the effect of measures taken. Monitoring according to the Annex IV of NEAPC means the quality of water, sediments and biota and measurements of or effects from activities or natural and antrophogenic inputs. It particularly addresses the criteria and time‑limits set in regard to land‑based pollution.
few examples show, that the approach to marine environmental assessment
is far from uniform. The objective is
introduction/activity by man (pollution) evaluated either for
individual or general reasons. The general target of assessment
often confined to marine living resources.
On the whole, marine biota is related to a sea area regardless of the
'turn‑ over'of ocean water. While the former is assessible, their
environment (the sea water) has changed. Insofar, impact assessment is
reduced to one aspect of the marine environment. The
state for marine biota concern is usally the immidiate concern, but
the 'stability' of ocean dynamics is what matters as well.
This was recently expressed as follows: "The assessment
would need to look ahead at least 25 years in addition to building on
past experience and the present status", while elaborating on efforts
by international organizations in this field. The topic was "Integrated assessment of
available scientific understanding, observations and data for
sustainable development and ocean management" to emphasize the
increasing debate about the oceans and the role of "scientific
integrated assessment is reliance on an "ocean image".
A model like legal set of rules is not available. National legislation seems rare, the European countries included. But the issue is discussed and has been addressed as a ‘new science‘ (and: frontier science). The main field of debate on marine environmental damage assessment is related to incidents by ships. The IMO Manual on Oil Pollution (1995) advice to arrange for surveillance of the oil slick and, by use of available meteorological and hydrographic data, prediction of its probable movement, and, that damage assessment should include arranging for an up‑to‑date check of the potential danger to birds, wildlife, fisheries and other environmentally sensitive features in the area. Damage in this respect can be used describing the damage to something and the legal consequences for the wrongdoer from such an event. If a law requires to undertake damage assessment it is meant as an undertaking to form a basis for the consideration and the application of the laws, civil, criminal and administrative rules and regulations. While criminal investigations and administrative fines procedures require only proof of the law breaking incident but not necessarily a full picture with regard to the damages incurred, the following discussion on the scope of damage assessment for legal purposes is confined to the civic aspect on compensation or restoration if possible.
basis can be either defined and regulated by law or has to be conducted
according to the applicable definition of pollution or corresponding
activities prohibited, e.g. dumping. As far as could be observed only
the U.S.A. have implemented assessment regulations recently, the
Natural Resource Damage Assessment Rules (NRDA)
as required by the US Oil Pollution Act 1990.
The NRDA shall apply to officials in conducting natural resource damage
assessment when natural resources and/or services are injured as a
result of an incident involving an actual or substantial threat of a
discharge of oil. The emphasis lays on restoration but the rules also
describes ‘Compensation Formulas‘ based on (1) field methods, (2)
laboratory methods, (3) model‑ based methods; and (4) literature‑based
example, if the assigned institution (trustees) can not design a
restoration plan (which has priority) it can choose from an extensive
menu of procedures (compensation formulas) including
computer models. Thus the "value" of loss can be determined which may
include amenities, like swimming, boating, hunting, or bird‑watching.
It must be established that the injuries in question have resulted form
the incident. The administration (trustee) has the right to make a
'presumption' which is presumed to be correct unless the responsible
party present evidence adequate to rebut the presumption. Burdening the
proof on the shipping industry in a field of immense uncertainties and
imbalance (see below) the Rules open the gates to administrative
(expert) arbitrariness. The ship insurance industry is anything but
happy, assuming that there is a high risk of uncontrollable and
excessive compensation claims.
Of the established regional marine environmental treaties non has taken up the subject. BSPC provides the ground in so far as it requires the signatories to cooperate in detecting polluted areas and to examine and to assess the risks while other convention require a system of monitoring and inspection to assess compliance with the rules, or, repeated monitoring or to give assistance to other contrasting states in investigating violation by ships of the existing legislation on antipollution. But rules of damage assessment are not given.
damage assessment is done on a case by cases basis initiated by the
authorized institution or authority or in case of litigation by court
assigned experts. The framework/guideline of task for the investigator
must be either derived from the applicable definition of pollution or,
Pollution damage is defined in very general terms by CLC as loss or damage caused outside the ship by contamination resulting from escape or discharge of oil from the ship, wherever such escape or discharge may occur including the costs of preventive measures and further loss or damage caused by preventive measures. However, compensation shall be limited to costs of reasonable measures of reinstatement but not loss of profit. Although oil pollution cases are possibly one of the best investigated in regard of their impact on the marine environment the application is not without constraints and question marks. In addition, the definition is in principle restricted to the impact on man, actually resulting to, economic losses, costs of clean‑up measures and remuneration of fisheries inspecting/ monitoring measures. In 1994 the Comité Maritime International (CMI) adopted Guidelines concerned with the admissibility and assessment of claims for oil pollution damage.
From a practical point of view the matter is
almost not existing, except in shipping or possibly in some very rare
individual cases. The 90% land‑source based marine pollution ‘pass‘
without damage assessment for national or international monetary
redress. Now one knows which part of these 90% could be or should be
regarded as damage to the marine environment. There is no other way but
to accept the situation for the time being. The present law system is
not capable of taking allowance of the issue. A recently adopted
Convention by European States on activities dangerous to the environment is too narrowly defined
to have a significant application on the ocean issue.
To apply legal provisions on pollution, the circumstantial facts must
meet a number of conditions to provide the means for establishing
liability. The evaluation requires reliable description of the
incidental circumstances , the reasons, kind and extent of damages, the
consequences of incident and particularly factors on which the
causality between the incident and the damage could be established. But
it is easier said than be done. Ocean water mixes and moves on.
Without a test site providing facts a substantial step on identification of reliable short and long term criteria cannot be expected. The whole system not specific kinds of pollution or specific ocean issues is to address. What is necessary are guiding principles on ‘balance‘. Balance is measured by ocean natural commons and activities by man according to impact. Without a fully employed ocean observing test site, which would provide a principle baseline for ocean assessment, the facts required to develop a political strategy on scope and aims of assessment seems remote to achieve. A strategy means foremost the ability to distinguish between important and urgent from less important or unimportant from the point of the oceans over any space and any time period.
a general sense "damage" should not be
defined as a monetary loss to man alone, but
any activity which injures 'ocean preservation'. Impact related is any
activity whether incident related or 'combined' input inducing
changes. In this respect marine environment damage assessment is an
impossible task. It actually requires full understanding of the oceans
with all the varying characteristics of the ocean waters and reactions
to ‘in‑puts‘: realizable or latent, direct or indirect, long‑term or
short term, reversible or irreversible. Reliable
categories on ocean ‘vulnerability‘ according to sources may possibly
of more efficient than relying an damage
assessment alone. Land‑based source pollution will remain difficult to
be addressed on an individual case. The present situation is hardly
acceptable for long. The shipping industry is almost the only marine
pollution source with international liability.
review indicates a wide range to conduct assessment, but with little
regard to the specifics of the marine environment. The open oceans or
large seas leave little room for comparisons between repeated
assessments. The water body is changing permanently. When regional sea
conventions require impact assessment they actually mean the impact of
land‑based sources, either as an initial preventive measure, or as
control of permanent input into the sea by rivers, air or other sources
and transmitter. Repeated assessment at the same geographical
location, is actually assessment of different waters.
If a sea, like the North Sea, is subject to a complete turnover of
water within 3‑9 months, the need of impact assessment exist only as
long as ‘input‘ continues. In a nutshell, impact assessment, as used
today, is controlling ongoing land‑ based source pollution in a small
area of interest (jurisdiction). In lakes and closed seas the water
remains within the basin for same time. Only here the meaning of
impact assessment provides a basis for comparisons between the past,
present and future.
A convincing practical or a legal framework on marine environment assessment has not developed. There are not even indications in sight which may lead to developments. For this reason the commitment by the Stockholm Declaration 1972, to develop international laws on liability and compensation has hardly any chance to be taken in consideration soon. Defined obligations and responsibility in legally binding terms is a essential means for sound ocean management. Meanwhile the marine environment drifts to an unknown state. Faced with immense problems and almost not existing international legal framework for land and air based source a search for solutions at a test‑site should be made.
A least two conditions a concept on marine environmental assessment should fulfill, general applicability and a service to man and the oceans. A strategy has not yet been formulated and is unlikely to happen in the foreseeable future. The oceans are simply too big, the interaction in the oceans and within the global environment too numerous and the system too little observable and in many respects too little understood. What is basically necessary are criteria aimed at sustaining a reasonable balance between the use of the sea and the oceanic system. Assessment in this respect would mean evaluating and categorizing all ‘activities by man‘ and to organize it legally.
this purpose it is necessary to
a) scientific (or general or practical research) assessment, and
b) legally required or relevant assessment.
the former (a) would be related to academic or practical work,
the latter (b) is designed for serving a legal concept.
A legally relevant impact assessment would have to address two topics,
a) Individual/incidental/accidental pollution as precaution or redress (e.g. economic loss), and,
b) all antrophogenic aspects in the scope of Article 192 UNCLOS comprehensively, to meet the obligation to protect and preserve the marine environment, based on two sources of legislation
a) rules and standards on individual and general source
related assessment, here after called:
quantification assessment, and
b) rules and standards on individual and general source related impact assessment, hereafter called: qualification assessment.
assessment would mean to identify the sources or activities which are
or are likely to have an impact on ocean dynamics (positive or
negative), and in any other way on sea‑water, sediment and biota and
the potentiality of impact in a categorized manner,
a) general, e.g. region, country, river, town, port, etc., or
b) individual, e.g. industry, power plant, factory, company etc., including any incident and accident ( but without damage assessment as means for redress, e.g. economic loss).
organized in this form, or any other form guided by Article 192 UNCLOS
would enable politics to respond with preventive measures or
compensatory means ( see Figure: Ocean Assessment) comprehensively.
If the global oceans are too complicated to develop a generally accepted concept quickly, it is advisable to look whether a smaller system could serve the purpose. The Black Sea is a option in this respect. Although it is only to a limited extend comparable with other seas it is nevertheless a basin with oceanic dimension. The specific feature of the Black Sea is no hindrance for the development of a strategy, vice versa, its continentality and severe environmental problems may increase the awareness for the need of more reliable solutions.
Black Sea has reached a point of state that it has become difficult to
identify the most urgent tasks. The priorities in a test‑site case are
different. They shall primarily enhance progress and capabilities in
general ocean management, while the test‑site investments and results
are beneficiary to the region subsequently, presumably very sustained.
indicated above, one of the tasks is directed at indication and
quantification of all sources relevant to the marine environment. As
land‑based (including air) is the principle concern, the task is
practical in nature. The real work starts with qualification
assessment. Based on a improving availability of an 'ocean image‘
(Model I) all sources of 'input' are to be classified on their actual,
or potential, or definitely not existing impact on ocean dynamics,
whether in the surface layer or deep water, directly or indirectly. The
evaluation of antrophogenic 'interference' in the ocean water structure
is the principle task. The very importance derives from the condition,
that the oceans are the ultimate force on the global and regional
climate stability. For this purpose is the identification of direct and
indirect sources forcing potentials to the best degree and detail
possible a necessary condition for good ocean management.
Evaluation of the indirect impact of organic substances would for example include the impact of red tides on the sea water exchange (horizontal and vertical) and local or general current system. Other sources might be easier or even more difficult to identify and classify as relevant on ocean (sea water) dynamics. The aim is to develop criteria and to set up an initial, but best possible, baseline. The steps to be taken according to results or after the test phase has been ended is to decide than and politically.
However, the task need not and should not confined to ocean dynamics only, but extended to biota and sediments as well. Biota would be included in the outlined assessment concept anyway. BSPC emphasized the link between the characteristics of biota and sea water temperature and composition. Detailed information on salinity and temperature is what the Model I aims to achieve. The further discussion is related to relevant marine topics with particular attention to the Black Sea conditions.
main problem of the Black Sea is land‑based pollution. The confined
waters offers the opportunity to trace pollution longer and more
detailed than under open ocean or large seas conditions. This may
include 'testing' the term pollution. The
evaluation of impact will face a particular challenge due to the two
water bodies with the cold intermediate layer (CIL) separating the two
waters and the Northwest shelf area. Here several rivers from
continental Europe contribute to Black Sea ocean dynamics and
pollution. While BSPC (Preamble) noted the input from
third countries the insufficiency to address this question legally,
assessment by quantification and qualification may provide the facts
for legal solutions.
a wider context, a comprehensive assessment could also lead to
reconsider certain aspects of the legal term of pollution, or how to
'assess' them and qualify the impact. A rather strange example for
illustration only. The term pollution includes "deleterious effects as
harm to living resources and marine life". The plaque Mnemiopsis is a
living resource and marine life. Thus an introduction of substance or
energy by man can be detrimental to the jellyfish but could turn out to
be a blessing for other marine life.
More practical is a conceptual framework for assessment requirements in oil pollution by vessels and related incidents (hazard goods). As indicated above the shipping industry is suspicious of increasing non‑transparent compensation demands due to by ‘new science‘ assessment technique and 'fantasy' compensation claims. A test‑site investigation on qualification assessment may provide criteria for a more standardized solution. For example: while damage assessment (injuries to human, to beaches, installation, fisheries etc.) is strictly confined to damage to man, the 'impact on the sea' including living resources and marine life ( if not subject to direct economic loss) is categorized according to volume of discharge, type of oil (or type of cargo), the sea area and made subject to a lump sum payment. The amount would be based on the potentiality of threat, adjusted according to knowledge and general binding in all jurisdictions. It is not only a subject of equality in international trade, but even more a subject of finding a reasonable relation to the other 90% sources which account for marine pollution. The present assessment praxis for vessel incidents has many flaws. As long as the ocean system is too little understood, 'scientific research assessment' and incident related 'damage assessment' should be strictly separated. The reasonable and international acceptability could be developed in a small ocean basin. The Black Sea is to see huge oil transports from the Caspian Sea region in the near future.
Until now the principle approach on marine protection and preservation is largely confined to the condition of the legal term pollution. Whether other uses of the sea have an impact on the marine environment has attracted little interest. A test‑site on qualification assessment would have to identify and consider any possible source of ocean forcing or other impacts and to establish (evaluate) the facts as accurate as possible. For example, impacts that contribute to changes in the sea surface layer structure in regard to salinity, temperature or currents due to activities at and in the sea. The relative high stability of the basin's two water bodies provide circumstances for obtaining more clarity in this respect.
meaning and scope of precautionary is rather imprecise. The Rio
Declaration 1992 requires in the most general terms a "precautionary
approach" when a threat of serious or
irreversible damage is possible. Lack of full scientific certainty
shall not be used as a reason for postponing cost‑effective measures. As outlined
previously, in legal documents the principle is used to assess proposed
activities or impact of pollution. The Black Sea situation needs a much
more sensible approach. Precaution is to observe between the natural impact (or threat) of the
hydrogen sulfide water body
on the sea surface layer and vice versa
the impact of man on the surface layer and subsequently on the deep
water body. The cold intermediate layer (CIL) for example could
possibly be a very useful object to improve the meaning of precaution
and up to which extend the principle should be applied.
as nutshell, the principle is good but toothless. It can not bit as it
is applicability in very limited range only. The extent is confined to
knowledge and meant as reciprocate, impact on man. What the principle
actually should have in view is its application from the point of the oceans, and defined as legal term reflecting
the obligation of Article 192 UNCLOS. The suggested strategy on
quantification and qualification assessment aims to change the wheel in
and closed seas might be subject to rehabilitated by man, the sea areas
off coastal ocean shores can not. Here, rehabilitation, if not by ‘self
purification‘, is done by oceans currents taking
polluted water somewhere else indefinitely or return it back one day in
the future. Whether the Black Sea can be subject to rehabilitation is
one thing, another question is that many useful and important criteria
and solutions may emerge if seriously and comprehensively addressed.
the word resetting may face opposition but there is hardly any better
one to distinguish a situation which is not rehabilitation even if used
not too narrowly. Meant is a substantial change of the marine
environment which is different from the traditional status either by
natural changes or 'deterioration' caused by man or, active
intervention by man. One day the Black Sea may be considered for
undertaking a "resetting". A substantial change would be of tremendous
importance for the international community in many ways with
considerable impact of defining assessment criteria and marine
The principle task is an inventory of all antrophogenic sources which are or cannot be excluded as counterproductive to the obligation to protect and preserve the marine environment. While the 'true ocean image' on a daily basis becomes available, the undertaking under Model II would have to
a) identify all sources not already listed by "quantitative assessment", and
b) categorize all listed sources according to
their impact on
aa) ocean dynamics,
in a staggered form of 'potentiality', including relevant interchanges.
The observational means by Model I would provide a solid baseline to address the relation man‑ocean comprehensively Further subjects are likely to turn out in high numbers. Some may be identified as urgent, or very significant, or only of general interests. The way to raise, to elaborate and to present them is to include in the model strategy. Thus the terms may emphasize the identification of fields of importance or urgencies. But the most important aspect of running a test‑site on assessment is transparency with regard to any step and any result presented. Only accessibility and clarity of presentation of all data and evaluating processes pave the way for transferring results into international binding laws.
should know what they are talking about and base decisions on save
facts. Politics sometimes seems not being fully aware of the dimension
of the oceans and the complexity of task ahead. For that reason they
have adopted legal concepts on the marine environment as they are used
to in land territories.
and preservation of the marine environment requires identifying the
scale of requirements resulting from the obligation. The question of
state responsibility in practice is still an open matter. Nevertheless,
any activity by man could be counterproductive to the state of the
ocean system. But by today’s knowledge and means it is
impossible to identify all sources which are or have the
potential to force changes and to evaluate their immediate or long term
impact on parts or the whole system. The
legal responsibility of states exist and the lack of knowledge require
steps to close the gap. The legal impact of responsibility and
liability must be based on a transparent concept and
equally applicable to everyone. Not every responsibility
which can not be observed need to result in legal damage compensation,
but may resorted to other measures either active or other regulatory
means. The decision is a matter of socio‑political priorities and
subsequently of laws and regulations. The legal concept
should observe all aspects which have
or may have an impact. The burden is to distribute among all
contributors on a reasonable fair and equal basis.
a global issue, the structure of responsibilities is based on
sovereignty and international and national laws. The present approach
to marine environment assessment and system
of liability is a factor of insecurity among states and legal
development due to differences in assessments procedures and
interpretation of applicable legal definitions. Without a
recognized level of equal and fair treatment among all
polluters, trust in a legal concept for the protection of the marine
environment is difficult to achieve. Comprehensive assessment is a
prerequisite for the identification of responsibilities and the basis
on which impact, preventive measures and compensation is to formulate.
These subjects not only play a major role for the understanding of the oceans but for the unification of national and international laws on liability, compensation or other compensatory matters. Litigation is a sufficient means for effectiveness. But courts have to stick to the laws. They can only contribute in accordance with the legal framework available. The handling of assessment and compensation for inflicting the marine environment is still far away from exploring the potential of legal responsibility and liability. Negligence in this respect is not only disregard to the ocean issue but may also undermine the legal principle of justice and international legal developments.
The Black Sea conditions provide an excellent field for more progress in developing the international law. Until now, the Stockholm Declaration from 1972 on State liability and compensation is an open matter. Defining marine environment impact procedures and drawing conclusions from the result is a precondition. But liability among states or persons is meanwhile only one side of the medal. A balance between mankind and ocean is an even more urgent subject.
A new approach in national efforts and cooperation on all institutional levels in marine and coastal management was urged by Agenda 21. As basis for action the Global Programme for Action 1995 emphasized that Regional cooperation and arrangements are crucial for success in protecting the marine environment from land‑based sources. The objectives given accordingly are
– Identification and assessment of problems;
– Establishment of targets and priority for action;
– Development and implementation of pragmatic and comprehensive
management approaches and processes;
– Development and implementation of strategies to mitigate and
remediate land‑based sources of harm to the coastal and marine
aiming at strengthening and, where necessary, create new regional cooperative arrangements and joint actions to support effective action, strategies and programs. While the call for cooperation is common in many international documents it could possibly be questioned whether it is nothing more than meaning to sacrifice some sovereign rights in order to achieve the objectives described. But how much sovereignty do States have over ocean water? The oceans apply their (natural) laws, defying ‘possession‘ by some-one else. Sovereign rights if meant as "holding dominion" looks somewhat displaced. Unlegally speaking the global ocean water system can only be subject to one sovereign power or to none. But even with this apparent conviction the paper would abstain from discussing this politically sensitive matter if not for the sake of Black Sea needs, the supporting effect on the models discussed earlier and the political constrains to navigation. This
Figure: Structure of Model III
with the inclusion of objectives like environmental control,
contingency planning, pollution prevention, law enforcement, claim
management and legislation a number of concepts could be addressed and
tested on their viability, usefulness and acceptance to the Black Sea
region or elsewhere. Initiating and running a model case can be defined
in any respect, e.g. excluding port areas or shallow waters. A test
case implies in particular a time limit with the inclusion of
reestablishing some or all concessions made on jurisdiction and
sovereign rights after the agreed time period runs out. As the number
of items worth to consider is almost unlimited the following discussion
can only touch some aspects. Based on the Model I
'ocean observing' and Model II 'assessment ‑ compensation' the model
‘one ocean ‑ one system‘ could be based on a concept as given in Figure
The structure indicated can vary in many directions but aims at minimizing the need for creation of new institutions or organizations while arranged temporarily only, but attractive to Black Sea countries as well as for third countries or international organizations. However, this paper cannot and aims not for more than to raise interest in such considerations and thus may more ask questions rather than offering any concrete concept. The principle goal is the optimal organization and making use of the Model I & II. But their effectiveness could be strongly enhanced by (temporarily) including further tasks and initiate more ‘ocean mindedness‘.
Ocean mindedness could be translated in: don't divide what belongs together. Some thousand years ago nature connected the Black Sea to the ocean system, extremely remote, but nevertheless significantly. Ever since the pure fresh water body ceased. Ever since a direct navigational strait with a water volume of roughly 3,500 km3 was established. One fifth is replaced annually, by surface water from the Black Sea and high saline deep water from the Mediterranean Sea ending in the northern basin. There it contributes to the anoxic water body, while the strait's water in the surface layer is brackish. The Straits and the basin belong to the same system.
Binding legal agreement do not constitute problems to ocean protection, but as a statement recently expressed: "In the first place, issues of national sovereignty, economic development, and economic security loom large, and states and their governments do not like to be told what they may do or not do in their own territory". Ocean water defies legal territorial concepts. The sea used to be treated as a commons. That changed only recently when coastal states obtained sovereign rights and jurisdiction over a zone of 200 Nautical Miles toward the open sea. One third of all ocean space transformed to national jurisdiction. The state boundaries now cross the sea accordingly. Every part, water and sea floor of the Black Sea belongs to a territorial sovereign. BSPC designed to protect the sea from pollution adamantly requires respect for national sovereignty and independence (Art.3, BSPC) first. Observations indicate that "until now international law has primarily made available unilateral and repressive instruments for its enforcement, especially the concept of State responsibility as well as the unilateral mechanisms of retortion and reprisal". While coordination is a prerequisite of BSPC, the Black Sea connection to the ocean system is governed by a fully separated set of rules. A disregard to the natural oceanic conditions is eminent. While this is the way it is done everywhere, here they are more obvious then anywhere else. Not only the oceans cannot be divided according to legal boundaries, marine pollution cannot either. To illustrate:
Comment concerning water from the Black Sea: The Marmara Sea receives via the natural exchange from the Black Sea, roughly 15 times more organic matter than that contained in the sewage discharged from Istanbul.
Comment concerning sewage entering Black Sea deep water: Even if tertiary treatment systems are constructed at a cost of approximately 10 billion USD, to control the nutrient load originating in Istanbul, will there really be a significant improvement in terms of eutrophication and in terms of the ecological status of the Marmara Sea, despite the nutrient loads brought in by the Black Sea.
It goes almost without saying, that the latter comment requires first the implementation of an action plan regarding the Danube before " the discharge of wastewater of Istanbul into the lower layer of the Bosphorus through a system of marine outfalls following primary treatment, seems to be an acceptable short term solution". The comments illustrate well the close connection of the ‘natural‘ water and the ‘polluted‘ water in both areas.
At least, BSPC establishes a forum for more cooperation. But cooperation is a piece‑ meal political process by unanimity of decisions (Art.20,BSPC) and national jurisdiction execution (Art. 16,BSPC). In addition Black Sea's in and out going polluted water and in and outgoing international shipping are fully excluded from efforts under BSPC. Her only the means of diplomacy can seek solutions. The number of prerequisite political and administrative processing of efforts is hardly to work as sufficiently and speed as the situation requires. While the meaning of cooperation is very general in term, particular Black Sea issues may be useful to address more specifically. Instead of protecting statehood, "the emphasis must be on learning about the nature of the problem, the experience of other coastal states in attempting to control land‑based pollution" recommended a eminent legal expert recently. Unfortunately, there is little to learn or copy from. Instead, convincing efforts, arrangements and results in pursue of effective ocean management in a test‑site case could serve as example elsewhere.
Historically and by international legal definition the Turkish Straits are internal waters and Turkey the sovereign. The Montreaux Convention provides international shipping with "freedom of transit and navigation" through the Straits (see Chapter I). From 35.000 ships passing the southern part (Canakkale Straits) and 50.000 ships the northern part (Istanbul Straits) about 75% is foreign tonnage. While they seek unhampered passage, no delays or any requirements beyond international standards and extra costs, the Turkish Government‘s concern is safety of navigation in environmentally sensitive waters.
The opposing interests inevitably establish a situation of conflict and if not solved is likely to continue for a long time. It would hamper solutions in other field of Black Sea pollution. While there are many political and legal points to argue this paper is to put the subject in context with ocean management and the question what 'regime' should prevail, or in other words could a 'one ocean' approach be convincing and urgently enough to compromise on otherwise contrary positions.
ocean pollution concern started with regulating oil pollution from
vessels in the 1950s the shipping industry is no longer the main concern. Shipping in general as vessel pollution is
highly regulated and controlled but also the most comprehensively
covered pollution source by an international legal framework for damage
compensation and insurance. During this
four decades, the concern of the industry was the assurance of equality
on rights, obligation and enforcement. The underlying question was
always fair economic conditions in international trade and access to
the trade. It includes equal treatment in all cases of pollution
regardless of jurisdiction. Even damage assessment can not be excluded
as "it is a subject that not only plays a major role for the
unification of civil liability but which at the same time puts
unification at risk due to the gaps in
present damage definition of unified law and the influence of national
environmental policy and national legal views and jurisprudence".
Black Sea regional economy is particularly sensitive on shipping
matters. Thus the Montreaux Convention is something the shipping
industry and the states reliant on shipping are reluctant to see
effected. In addition from the total of vessel source pollution ship
accidents account only for a percentage of 20%
while habor operations account for more than 50%. And as far as accidents are the concern quick
and proper response accounts often more than anything else in
minimizing the effect of an incident. Ships in transit through the
Straits and in the Black Sea is a minimal threat to the regional marine
environment compared to other sources. Proportions
should matter. Far more severe is land‑based pollution with 90%.
To reverse the Black Sea environmental situation the Black Sea countries must have the economic means earned by regional industry and competitive in international trade of which shipping plays an important part. If shipping is required to contribute, it should be the burden of the whole region within a general Black Sea/Turkish Straits concept of ocean and navigation management concerned with the regional marine environment. With regard to the overall problems of the Black Sea and the Straits the shipping issue is a small one and a test field on willingness on progress in developing and the implementation of pragmatic and comprehensive management approaches and processes as required by the Global Programme for Action 1995
It is the responsibility of the state (flag state) who granted a vessel the right to fly its flag, to identify instances of a vessels not compliance with international standards. While deemed not sufficient enough coastal states were given a number of rights including inspection for identifying substandard ships. Port State Control is a method of checking on the flag state’s success in enforcing the provisions of the international conventions covering safety and pollution prevention standards on merchant ships. Comparative agreements have been implemented, although not for the Black Sea. Meanwhile the European Community requires more stringent checks. Regional effectiveness could be enhanced by a co‑ordinated geographical coverage organized by and with participation of all riparian countries. To protect the regional seas from substandard ships in international trade, a survey or initial survey the most appropriate time and place is before the vessel enters the Black Sea or before a ship bound for the Straits leaves a Black Sea port.
international instrument available is the IMO Convention of Oil
Pollution Preparedness, Response and Co‑operation, 1990 while UNEP Conventions
and Protocols have developed cooperative programs for dealing with
oil and hazardous incidents.
Bilateral agreement exist.
The following point could be considered:
1. A committed approach on Model I (observation) would require ship capacity, which could be partly or wholly included to the subject matter or form a core unit/coordinating role.
2. Efficiency is difficulty to achieve with mere cooperation. Competent
preparedness is expensive and a matter of assigned responsibility and liability (insurance) together with redress in case of 'insufficiency'.
3. The Straits certainly need the most efficient emergency response possible as far as vessel pollution is concerned, but so does the Black Sea. There is little if any point for two separate systems and responsibilities. The shipping industry or Black Sea countries should
contribute to one emergency system only.
Navigation from and to the Black Sea can often take as much time as proceeding to the Black Sea port of call. From the point of marine environment protection, any and all precautionary means established, have to be observed, executed and controlled anywhere throughout the region based on the same set of rules, standards and procedures, as well as subsequent costs, expenses and compensation. The navigation management is a concern of all riparian countries based on equal involvement, contribution and redress.
At least in regard to vessel pollution and preventive measures the set of civil, administrative and criminal laws require to be applicable and enforced in a uniform manner by one jurisdiction. If that is guaranteed, neither the regional based shipping industry is likely to complain nor is the navigation issue continue to remain a subject of concern.
Conducting a test‑site is assumed to be an international undertaking. With Third Party monetary contribution and/or participation the agreed conditions for conducting the undertaking could either subject to a separate International Agreement (Art. 5(4) BSPC) or subject to an Annex to the BSPC (Art. 20‑22). Any issue included in regard to the Turkish Straits would need an international agreement.
could be the "Meeting of Contracting Parties" plus non‑ Black Sea States if so agreed (Article 19 BSPC). It would supervise the undertaking and consider and approve Amendments and Annexes to BSPC. The Black Sea Commission (Article 17 BSPC) would either function as subordinate body to the Board (Article 18 BSPC) or given a designated role in a ‘test‑site‘ programme with certain obligations and responsibilities.
A separate Trust is just an option. If institutionalized it could be assigned with a number of obligations. The underlying point is forming/ developing a ‘compensatory‘ monetary mechanism between ocean pollution/activities and ocean protection and preservation, or if expressed pathetically: to give the ocean what was taken from the ocean. The Trust is either as a subordinated organ of the Board/Authority or constructed more institutionalized (by assignment to the Ministers of Finance or the National Central Banks of the riparian countries) the obligation could comprise the management of some or all monetary matters, e.g. the contribution or compensation of
– Black Sea States – Third States
– Claim – User charges
– Tax/Levies – Fees
but also to act as plaintiff on behalf of the Board or as "custodian" of the waters in the Black Sea and Turkish Straits. The funds of the Trust are to be used for damage compensation (to countries and individuals) and for ocean management.
According to Article 16 BSPC (Responsibility and liability) there is little room to discuss this matter, as it is up to every State Party to BSPC to implement rules on liability for damage and recourse, while obliged to cooperate in developing and harmonizing their laws. One of the best means, unified, transparent, equal judgments by experienced courts to serve the Black Sea issue is largely ignored. It is a field where common juridical systems are of little help. The Black Sea problems seem sufficiently only addressed with a ‘Black Sea court‘ (system) to ensure not only progress in regard to the protection of the sea itself but simultaneously fair competition, compensation standards, as well a equality in rights and obligations including as core issue the comprehensive protection of the Black Sea itself. At least the opportunity given by the UNCLOS Dispute Settlement System with access to International Tribunals, if so stipulated in an agreement, is a option worth to consider.
There are a number of institutions which could be assigned (e.g. regional sea commissions) or asked to accept temporarily management functions e.g. the International Sea‑bed Authority/Jamaica, UNEP/Nairobi, IMO/London, IOC/Paris or a established EU Institution or Programme. The assignment or participation in Model I , Model II and other tasks could be under sole or joint responsibilities. The extent and conditions depend on the willingness of man‑power input, contribution and prosepective results. The International Sea‑bed Authority which has no jurisdiction over parts of the deep sea floor in the Black Sea due to the narrowness of the basin could act only with the approval of the Assembly of the Authority (Article 160 UNCLOS). But to conduct deep‑sea mining on day the Authority need to have experience. For UNEP or other international organizations a ‘show‑case‘ in coastal sea management seems no less attractive. The involvement of these institutions in one or the other way would not only avoid creating new entities but assure a wide international interest in a test‑site programme and its results. After all, BSPC (Article 5(5)) states that the Contracting Parties will cooperate in promoting, within international organizations found to be competent to them, the elaboration of measures contributing to the protection and preservation of the marine environment of the Black Sea. They noted the pollution input emanating from third countries in Europe and corresponding deficiencies in existing international agreements to cover some aspects in this respect (Preamble, BSPC).
are obliged to protect and preserve the marine environment. All acts or
omissions inconsistent with this responsibility imply violation.
Wrongdoing implies reparation. So say the principles of international
laws. In practice the effect is not existent. The principle stands
without legislation. 90% of marine pollution is not scrutinized for its
potential as a violation. The mechanism of law to act before being held
liable is ignored, while the state of coastal waters and the oceans
drift to an unknown status. The insufficient use of law has many
reasons. The core of the matter is lack of reliable facts. In a
nutshell, the oceans are too little understood, even less the impact of
activities by man on the sea and the system. It will not be understood
for long. The ocean system is too big and a complex matter as well. It
may take many decades to realize what actions could and should have
been taken much earlier, to avoid irreversible ocean changes through
anthropogenic influencing. Influencing can change ocean dynamics,
physics, or chemical structure and subsequently the climate.
Influencing can effect the marine biota and marine sediments.
A smaller system with oceanic conditions could shorten the time period to gather experience and principles for legal developments. The Black Sea offers the proper dimension and conditions for being used to concentrate on two urgent task under test‑site conditions. The ocean system must become one day 'transparent' by a computed 'true ocean image'. The image must be available frequently and detailed enough to detect antrophogenic causing and to forecast the impact far ahead. For this purpose one has to know the relation between the number of observed true data and the capability of computer science to provide a true image and to forecast the future state of the oceans. As it is also necessary to identify and evaluate any antrophogenic impact on ocean dynamics, the development of a test‑site ocean image could be used to form a baseline for legal developments. To define applicable responsibilities anthropogenic impacts on ocean dynamics, marine biota and marine sediments the test‑site categorizes the potential of threat and considers other legal concepts and stipulation relevant to protect and preserve the seas.
A closed sea with a narrow connection to the ocean system provides all principle ingredients for running experimental models on task to done, but impossible to achieve in the oceans themselves for a long time. It would also minimize the risk of misinvestment. The Black Sea is a 'miniature ocean' with severe ecological problems. The Black Sea region has economic problems. Black Sea navigation faces political problems. All problems have in one or the other way to do with the marine environment. Black Sea countries could prove that the concern for the marine environment is superior to statehood and national jurisdiction, recognizing that the ocean system can not be divided, that marine pollution in the sea cannot be divided and that international shipping should not be divided. The Black Sea as test‑site would be a beneficiary for the riparian countries and the community of states. Without more stringent progress in ocean matters the industrialized world may not know for long, how to establish a "productive life in harmony withnature".

 The formation of the cold intermediate layer (CIL) is defined by the strong salinity input to the Black Sea stratification and heating of the deep‑water mass by warm Mediterranean water. A strong halocline ( a layer of sea water with which a marked salinity gradient is present, furnishing significant clues to the origin and and movement of watermasses) restricts the depth of winter convection.

 The Black Sea suface temperature varies from 7‑8°C in winter to 22‑26°C in summer. Baltic surface temperature varies from 0‑3°C in winter and to 13‑18°C in summer; at depth of 80m and below the temperature is 2‑6°C.
 The water salinity in the Northern Baltic (fresh‑water) and Southern Baltic (Kiel Bight > 15‰) is very different. In the central part 6‑7 ‰ at the surface and 10‑13‰ at the sea bottom.
 The Baltic has periodically anoxic water at the sea floor in the range 0‑20% of the total water volume. In the Southern Baltic this water is partly ventilated by rare ‘crash‘ inflow of high saline water from the North Sea.

 "Responsibility" is here used in a wide sence. In law the term "responsibility" usually means the consequences arising from the breach of obligations (see next Footnote) and subsequent liability(redress).
 A obligation termed as widely as in Art.192 UNCLOS, is imposing general responsibilities rather than immidiately binding legal duties. Cf., Art.304 UNCLOS: "The provisions of this convention regarding responsibility and liability for damage are without prejudice to the application of existing rules and the development of further rules regarding responsibility and liability und international law".
 In law the term is "liability", the duty to compensate damage according to legal responsibilities.

 Ibid., Excerpt: "Scientific assessment would not discuss the political situation, jurisdiction, the legal regime, demographic changes and societal pressure, such considerations will, of course, dictate many, if not all, of the problems to be addressed. The assessment would evaluate the ocean knowledge that we have, or need to have, to solve present and future problems, including the capacity of countries, at all levels, to deal with these problems"

 Since the 17th century the legal view on maritime jurisdiction claims required the means of "effective power" sufficient enough to defend the claim (e.g. the range of cannons for establishing a territorial sea). Only later the governing principle "freedom of the sea" emerged. In 1927 the Permanent Court of Justice held, that the principle means: "the absence of any territorial sovereignity upon the high sea"; (PCIJ, Ser.A, No.10, Steamship "LOTUS").
