7 The lowest salinity is recorded in the Gulf of Bothnia where it is 0.1%-0.4% at the surface and 0.3%-0.4% near the bottom, while the highest is in the Southwest Baltic proper where the figures are 0.7%-0.8% and 1.5%-1.7% respectively. Dybern, supra note 4, at 16.

8 Since 1900 the salinity of the Baltic Sea has increased by about O.lfo-0.2%. Ibid. In 1951, 200 cubic kilometers of saline water were pushed into the Baltic in three weeks. More recently, storms which flooded parts of Denmark in January 1976 were a blessing for the sea region, pushing record amounts of saline ocean water into the stagnating Baltic, thus renewing its water and speeding up the flow of the surface brackish layer out into the North Sea. Ch. Science Monitor, January 14, 1976, at 4. The inflow of the oxygen-rich seawater into the Baltic may have contributed to higher fish catches in the recent years. Carroz, J.

11 The first basic source of information was the ICES Report, note 4 supra. It was prepared by the Working Group on Pollution of the Baltic, established in 1968 by the International Council for the Exploration of the Sea (ICES). ICES is an international organization, founded in Copenhagen in 1902, whose objective is to encourage scientific research relating to the exploration of the sea and to coordinate the activities of its members. The members of ICES are Belgium, Canada, Denmark, Federal Republic of Germany, Finland, France, Iceland, Ireland, Italy, Netherlands, Norway, Poland, Portugal, Spain, the Soviet Union, the United Kingdom, the United States, and the German Democratic Republic. Alexander, supra note 6, at 99 note 45; N.Y. Times, January 26, 1975 at 36, cols. 3–6. ICES has cooperated closely with research organizations and governments of the Baltic countries both before the conclusion of the Helsinki Baltic Convention in 1974 and thereafter. Its latest report is a prestudy entitled Assessment of the Marine Environment of the Baltic Sea Area, presented for the use of the Interim Commission at the 4th meeting of the Scientific and Technological Working Group at Turku, Finland, August 23–26, 1977. See Report of the 4th Meeting of the Interim Baltic Marine Environment Protection Commission, Helsinki, November 15–18, 1977 (hereinafter Interim Commission Report 1977).

15 See Dybern, supra note 4, at 18. (Table 2 showing detailed figures for sewage and industrial waste pollution of the major coastal regions of the Baltic.)

36 The oil spill from the tanker Paha, which ran aground in the Finnish waters in 1969, provided a good example of the hazards of oil spills in cold waters. 25 to 30 percent (2,400 to 3,000) of the birds in the affected area, mostly eider ducks, died as a result of the accident. Leppakoski, E., Effects of an Oil Spill in the Northern Baltic, 4 Marine Pollution Bulletin (No. 6) 93 (1973)CrossRefGoogle Scholar. More recently about 1,600 tons of oil leaked from the Soviet tanker Tsesis 30 miles south of Stockholm. This was the worst oil spill in the Baltic. N.Y. Times, October 29, 1977, at 5, col. 3; Ch.

47 In Denmark a Ministry for Environmental Protection was created in 1971; Lutz 453. See also C. H. Jensen, The Law and Practice Relating to Pollution Control in Denmark (1976). In the German Democratic Republic, where antipollution control is among the best on the Baltic, there is a Ministry for Environmental Protection and Water Economy, set up in 1972; See Sand, P. H., The Socialist Response: Environmental Protection Law in the German Democratic Republic, 3 Ecology L. Rev. 451–505 (1973)Google Scholar. In Sweden there is a National Environmental Protection Board, forming part of the Ministry of Agriculture and supervising pollution control, and a Franchise Board, an independent body issuing permits and licenses. On the Swedish pollution control system see Oecd, Environmental Policy in Sweden (1977). See also L. J. Lundqvist, Environmental Policies in Canada, Sweden, and the United States: A Comparative Overview (1974). In West Germany there is a special Cabinet Committee for Environment coordinating pollution management and an Environment Office directing research and representing the federal government in international environ-mental matters. See Lutz, 452, 454. See also H. Steigeh & O. Kimminich, The Law And Practice Relating To Pollution Control In The Federal Republic Of Ger-Many (1976). In the Soviet Union water pollution is under the supervision of the Ministry for Reclamation and Water Management; in Poland, the Ministry of Local Economy and Environmental Protection.

98 Final Act of the Diplomatic Conference on the Protection of the Marine Environment of the Baltic Sea Area, Helsinki 18 to 22 March 1974, done March 22, 1974, 13 ILM 544 (1974). The text of the Baltic Convention is reprinted at id. 546. Despite optimistic forecasts (see, for example, Popiela, W., Konwencja o ochronie Brodowiska morskiego Baityku [Convention on the Protection of the Marine Environ-ment of the Baltic], 30 Państwo I Prawo (No. 7) 96, at 101 (1975)Google Scholar; Koschwitz, supra note 19, at 239) , the Baltic Convention is not yet in force since to become effective it must be ratified by all the seven Baltic states (Art. 27 ). As of January 1, 1978 it had been ratified by Finland (June 27, 1975), Sweden (July 30, 1976), the German Democratic Republic (January 6, 1977), and Denmark (July 20, 1977). According to die statements of the respective delegations to the 1977 meeting of the Interim Commission, the Federal Republic of Germany expects to ratify the Convention in 1978; Poland after 1978; and the Soviet Union as soon as possible after completion of necessary implementa-tion measures. Poland is carrying out a program of investment projects aiming at full implementation as soon as possible of the requirements of the Convention. The existing possibilities do not allow ratification in 1978. See Interim Commission Report 1977, at 3. Under its Article 29 the Baltic Convention is drawn up in a single copy in English. Official translations into the six languages of the Baltic states were to be prepared and deposited with the signed original. The Convention consists of 29 articles and annexes which elaborate the concise provisions of the main body of the Convention. The Annexes are as follows: I—hazardous substances; II—noxious substances and materials; III—land-based pollution; IV—pollu-tion from ships (this very long Annex, partially incorporating the provisions of the 1973 IMCO Convention, has eight Regulations and five Appendices); V—exceptions from dumping prohibition (five Regulations); VI—cooperation in combating marine pollution (ten Regulations and an Appendix on incidents involving harmful substances, which includes five Regulations). Finally Annex B includes seven Resolutions (applica-tion by other states of special rules for ships; reception facilities; navigation through the entrances to the Baltic; uniform reporting system; safety of navigation; application of Article 21 to future treaties; and Interim Commission). Under Article 20, the Annexes form an integral part of the Convention. Preparing the Convention in two parts is a drafting technique frequently used in conventions of this kind since under Article 24 of the Convention the procedure for amending Annexes and adding new ones is simpler than for amending the Convention's text itself. Generally speaking, the Commission itself adopts annex amendments proposed by a Party, recommending them for acceptance. An amendment is deemed to have been accepted at the end of the period fixed by the Commission unless one of the Parties has objected. Cf. 1973 IMCO Convention, Art. 16 (2)(f).See also Mensah, T. A., International Conventions Concerning Oil Pollution at Sea, 8 Case W. Res. J. int'l. L. 110, at 122 (1976)Google Scholar. Amendments to the articles themselves may be proposed by each Party and are communicated to all through the Depositary Government. Notifications of acceptance by all are necessary for an amendment to become effective (Art. 23). A conference for purposes of a general revision or amending may be convened with the consent of all Parties or at the request of the Commission (Arts. 22 and 23 (2)). The Baltic Convention is not subject to any reservations, but a Party may suspend the application of an annex or a part thereof for a period not exceeding one year (Art. 25(1)(2)).

115 Consent to accession by all the seven Baltic states could at least partially reassure those who believed that absence of extra-Baltic states from the Gdańsk and Helsinki arrangements meant that the Baltic was clearly “juridically becoming a closed sea.” See Miljan, T., Mare Clausum Balticum and the Law of the Sea, Osteuropa Recht (No. 2) 103, at 117 (1972)Google Scholar.

131 The Scientific and Technological Working Group set up by the Interim Commission (see note 11 supra and text at notes 173–175 infra), agreed at its 1977 meeting that the elimination of DDT's and PCB's should be achieved by “all possible means.” It called upon the seven governments to present national reports on these hazardous substances before the next meeting of the STWG in 1978.

133 This list is another version of the harmful substances listed in Annexes I and II of the 1972 London Convention on the Dumping of Wastes at Sea (see note 71 supra). Mercury, cadmium and their compounds are considered the most dangerous substances “for urgent consideration.” The other category includes 16 groups, such as antimony, arsenic, copper, lead, phenols, cyanides, radioactive materials, chemicals used in paper, cellulose and wood pulp industry, oil and wastes from petrochemical industry, pesticides, herbicides, and slimicides other than DDTs and PCB's. Also included are substances having adverse effects on the taste or smell of products for human consumption or on the water itself, reducing the amenity value of the sea or seriously interfering with legitimate uses of the sea.

139 At the meeting of the STWG (see text at notes 173–175 infra) at Turku, Finland in August 1977, attended by delegations of the seven Baltic countries and an observer from ICES, it was recognized that in elaborating common criteria for discharges of harmful substances, both ecological and water use criteria and technological standards must be taken into account. A special Working Group on Criteria and Standards was called upon to investigate whether the establishment of numerical values (water quality criteria) and applying technical criteria and emission and immission norms was possible. As noted by the STWG, useful work on developing criteria and standards for discharges of harmful substances was being conducted within the framework of the European Community in fulfillment of the Community's directive of May 4, 1976, 15 ILM 1113 (1976).

191 The framework for assessing the soundness of marine regional planning, suggested by Alexander(supra note 6, at 86–87, 109), provides good guidelines for venturing an answer to this question. This framework is partially adopted here to assess the Baltic marine regionalism in managing pollution.
