1 The Gulf of Maine covers approximately 25,000 square miles and has an average depth of 150 meters. A major feature in the area is Georges Bank, long a famous fishing ground, now an area of oil and gas potential. Shaped like an oval, Georges Bank is about 180 miles long and 90 miles wide, with an area of approximately 12,000 square miles. To the northeast, Georges Bank is separated from Browns Bank by the Northeast Channel or Fundian Channel, about 240 meters deep; to the southwest, the shallower Great South Channel, about 80 meters deep, lies between the Bank and Cape Cod. Most of Georges Bank is 30 to 80 meters deep. For more geographical information, see generally S. Apollonio, The Gulf of Maine passim (1979).

2 The territorial sea boundary starts at a designated point in the mouth of the St. Croix River, passes in a southwesterly direction between the U.S. coast of Maine and the Canadian Deer and Campobello Islands to a fixed point in the Grand Manan Channel, and then moves southwesterly through the middle of the Channel until it meets a point where the distance from the nearest base points becomes 3 miles.

Before issuing the Proclamation, the United States Government contacted the Governments of Canada, Mexico, the United Kingdom, and the Soviet Union; however, there was no challenge from any country. See 4 M. Whiteman, Digest of International Law 753 (1965). The purpose of the “equitable principles” was to encourage states to reach an agreement based on “a sense of fairness” by employing the most appropriate method or methods “case by case” in the area concerned.

7 The U.S. Department of State issued a public notice on Feb. 12, 1970 concerning its position with respect to the Georges Bank continental shelf, which it had already expressed to Canada in a diplomatic note of Nov. 5, 1969:

See 35 Fed. Reg. 3301 (1970).

8 The average estimate of recoverable hydrocarbon deposits on Georges Bank as a whole is 0.9 billion barrels, and 4.4 trillion cubic feet of gas, based on the United States Geological Survey. Of this, about 7 to 10% might be deposited in the disputed northeastern third of Georges Bank. See U.S. Geological Survey, North Atlantic District, Georges Bank Monitor 2 (No. 1, July 1980). Because of the possible environmental impact upon fisheries, not all of the oil and gas would be recoverable. Hydrocarbon reserves in the undisputed U.S. zone of Georges Bank relating to the Outer Continental Shelf (OCS) Sale No. 42 are estimated to be 123 million barrels of oil and 870 billion cubic feet of natural gas, having a net value of$588 million. See U.S. Dep’t of Commerce, National Oceanic and Atmospheric Administration, Georges Bank Marine Sanctuary Paper 24–49, reprinted in U.S. Dep’t of the Interior, Final Supplement to Environmental Statement, OCS Sale No. 42, at 515–20 (1979). Based on the adjusted value of 1978 landings of $167 million, the value of the fisheries of Georges Bank over the next 20 years would be estimated at $3.34 billion. Ibid. Comparing this figure with the net value of the hydrocarbon deposits, which are likely to be exhausted in one generation, it is fair to conclude that the renewable fisheries resources are much more valuable than the hydrocarbon deposits in Georges Bank.

15 The International Convention for the Northwest Atlantic Fisheries, signed Feb. 8, 1949, 1 UST 477, TIAS No. 2089 [hereinafter cited as ICNAF], regulated fisheries in the area bounded by the northeast coast of the United States, the east coast of Canada, the west coast of Greenland, and two lines: one running south from a point off the southern tip of Greenland, and the other running east from a point off the east coast of New Jersey. Because of conflicts with the FCMA, supra note 11, which regulates the 200–mile fishery zone, the United States withdrew from ICNAF on Dec. 31, 1976. However, Canada remained a member primarily because of its interests in the Grand Bank fisheries beyond its 200–mile fishery zone. See 75 Dep’t State Bull. 103, 146 (1976); 76 id. at 95 (1977).

16 The tiny granite islets have passed unnoticed by the public. They are located about 10 miles southeast of Maine and about 11 miles southwest of Grand Manan Island, New Brunswick. Although the Canadians have maintained a lighthouse there for the past 140 years, it has been reported that fishing grounds around the islets are worked by American lobstermen. See Ward, K., International Boundary Ill-Defined Since 1783; Tiny Island May Prove U.S. Canada Friction Point, Christian Science Monitor, Sept. 27, 1976, at 20Google Scholar, cols. 1–4.

17 On March 1, 1977, when the 200–mile exclusive fishery zone took effect, the U.S. Government stated its position with regard to this unclaimed area:

See 42 Fed. Reg. 12,940 (1977). In contrast, Canada has so far taken no comparable action with respect to this “unclaimed area.”

25 Maintaining that its policy and practice should conform with evolving legal principles of delimitation of maritime boundaries between states, Canada held that “certain projections of the United States’ coast have a distorting effect on the placement of the equidistance line and, therefore, constitute ‘special circumstances’ under international law.” See Communiqué No. 39, note 21 supra.

26 The United States “considered the claim to be without merit” and asserted that “any attempt by Canadians to fish beyond the initial Canadian claim would meet with United States enforcement action.” See U.S. Dep’t of State, File No. P78 016–2316, reprinted in 73 AJIL 132 (1979).

Subcomm. on Fisheries and Wildlife Conservation and the Environment of the Comm. on Merchant Marine and Fisheries, 96th Cong., 2d Sess., Oversight report on the U.S.-Canada East Coast Fishery Agreement and Boundary Treaty 18–21 (Comm. Print 1980) [hereinafter cited as 1980 HOUSE Rep.]. Opponents of the Fisheries Agreement asserted that the entitlement for fish stocks was generally unfair to the United States. For example, the shares for fish stocks in the Georges Bank area (5Ze)—including scallops: Canada, 73.35%, United States, 26.65%; cod: Canada, 17%, United States, 83%; haddock: Canada, 21%, United States 79%; and after 6 years, herring: Canada, 33.33%, United States, 66.67%—were unfair to the United States because if there is a split decision in the boundary settlement, Canada would have less than one-sixth of Georges Bank or one-eighth of the Georges Bank area (5Ze). See 1980 Senate Hearings, supra note 43, at 172–73. They particularly complained about the 26.65% entitlement to scallops in Georges Bank, because this share, based on historical averages from 1965 to 1977, did not take into account U.S. scallopers’ interests in Georges Bank before 1965 and accorded too much weight to the Canadian interest in the Bank, which had begun only in the early 1960’s. They also pointed out that the average failed to take into account that in recent years the U.S. share had risen from 26.9% in 1977 to 40% in 1979.

71 In the North Sea Continental Shelf cases ([1969] ICJ Rep. 3), the parties asked the Court to indicate the principles and rules of international law in order flexibly to determine the continental shelf boundaries later by negotiations. However, in the Anglo-French Continental Shelf arbitration (1977), supra note 24, the tribunal was asked to decide the course of the boundary. After reviewing the 1977 award, the United Kingdom alleged that there were errors in the depiction of the boundaries: first, in the Channel Islands area, because of the selection of certain base points in the United Kingdom’s disfavor; second, in the Atlantic region, because of the differences caused by the scale distortions between the rhumb line drawn by the tribunal as the straight line on a Mercator chart and die geodetic line, which the United Kingdom preferred, drawn on the surface of die earth. In a second decision in 1978, reprinted in 18 ILM 462 (1979), the tribunal accepted the argument of the United Kingdom relating to the base points in the Channel Islands area, and rectified the course of the boundary. In the Atlantic region, however, the tribunal rejected the United Kingdom’s allegation, not because it had practical or theoretical reasons for preferring the rhumb line, but because equitable considerations had already been correctly taken into account by employing the half-effect method of delimitation relating to the Stilly Isles.

In order to avoid another round of disputes over the interpretation of the decision of the Court, as in the 1978 Anglo-French award, the United States and Canada arranged sophisticated plans. Two maps—Canadian Hydrographic Service Chart No. 4003, and United States National Ocean Survey Chart No. 13006—were designated for the depiction of the geodetic boundary line on the basis of the 1927 North American Datum. The Court, including any technical experts, is to consult with the parties as may be necessary concerning any common computer programs of the parties for technical calculations. Special Agreement, supra note 30, Arts. II and IV.

72 This point is located about 21 miles from the disputed islet of Machias Seal. See provisions cited in note 70 supra.

73 It is not certain why the parties requested that the Court determine the boundary line up to a certain point in the designated triangle instead of, e.g., up to the 200–mile limit, or the 1,000–meter isobath. See provisions cited in note 70 supra.

74 Since the United States still maintains its traditional position of a 3–mile territorial sea, while Canada claims a 12–mile limit, this short boundary to be delimited may or may not be called a territorial sea boundary. See note 16supra. The rules for the delimitation of the territorial sea are slightly different from those for the continental shelf/exclusive economic zone. Compare Art. 12, Geneva Convention on the Territorial Sea, infra note 80, with Art. 6, Geneva Convention on the Continental Shelf, infra note 78. Compare also Art. 15 with Arts. 74/83 of the Draft Convention on the Law of the Sea, supra note 66.

75 The continental margin in the Gulf of Maine area extends into the Atlantic about 110 miles beyond the 200–mile limit. According to Article 76 of die Draft Convention on the Law of the Sea, the outer edge of the continental margin will be established “by straight lines not exceeding 60 nautical miles,” connecting either “the outermost fixed points at each of which the thickness of sedimentary rocks is at least 1 per cent of die shortest distance from such point to the foot of the continental slope,” or “fixed points not more than 50 nautical miles from the foot of the continental slope.” However, the fixed points shall not exceed either 350 miles from the baselines from which the breadth of the territorial sea is measured, or 100 miles from the 2,500–meter isobath.

103 At the outset of the discussions of Negotiating Group 7 at the spring session of 1978 in Geneva, the proequidistance group of 22 states proposed the following draft: “The delimitation of the Exclusive Economic Zone [Continental Shelf ] between adjacent or opposite States shall be effected by agreement employing, as a general principle, the median or equidistance line, taking into account any special circumstances where this is justified.” See Conf. Doc. NG7/2 (May 1, 1978).

The proequity group of 29 states in turn proposed the following draft: “The delimitation of the economic zone or continental shelf between adjacent or/and [sic] opposite States shall be effected by agreement, in accordance with equitable principles taking into account all relevant circumstances and employing any methods, where appropriate, to lead to an equitable solution.” See Conf. Doc. NG7/10 (April 20, 1978).

139 Article 19 stipulates that “[a] State may, when signing, ratifying, accepting, approving or acceding to a treaty, formulate a reservation unless: (a) the reservation is prohibited by the treaty. . . .” The United States may also argue that its objection of July 16, 1970 to the Canadian declaration simply left the matter in dispute between the two countries in light of the language of Article 21(3) of the Convention, which provides that “[w]hen a State objecting to a reservation has not opposed the entry into force of the treaty between itself and the reserving State, the provisions to which the reservation relates do not apply as between the two States to the extent of the reservation.” See generally Convention on the Law of Treaties, done at Vienna, May 23, 1969, UN Doc. A/CONF.39/27, Arts. 19–23, reprinted in 63 AJIL 875 (1969), 8 ILM 679 (1969).

140 Article 12(1) of the Continental Shelf Convention, supra note 78, provides that “[a]t the time of signature, ratification or accession, any State may make reservations to Articles of the Convention other than Articles 1 to 3 inclusive.”

142 For the convenience of analysis, the roughly semicircular Gulf area inside the hypothetical Gulf closing line between Cape Cod and Nova Scotia drawn by discounting islands shall be called the “inner area,” and the “outer area”—comprising the major feature of Georges Bank in the middle, Browns Bank near Nova Scotia, and Nantucket Shoal near Cape Cod—roughly resembling another half of die circle shall be called die “outer area of major interest.” The area to be delimited by the Court is within the 200–mile limit. The dimension of the 200–mile zone may be calculated by forming two hypothetical lines perpendicular to and constructed at both ends of the Gulf closing line. The area to be delimited will be further extended up to the limit of the continental margin.

143 The ratio of the lengths of the coasdines may be arguable. If the hypothetical closing line of the Bay of Fundy is not taken into account, then the ratio would be approximately 4 to 1. In measuring the lengths of die coastlines in the Gulf of Maine, it seems fair to discount the Canadian coastlines in the Bay of Fundy and to recognize the hypothetical Bay closing line as a part of the Canadian coastal frontage, not only because substantial areas of die Bay have been either incorporated into the internal waters by drawing straight baselines, or engulfed by the expansion of the territorial sea from 3 to 12 miles, but also because Canada has exercised exclusive fishing jurisdiction since late 1970 by drawing fisheries closing lines in the mouth of the Bay.

145 The sole reason for the birth of the thalweg doctrine developed since the beginning of the 19th century was to preserve equal rights of access to the main channel of navigation. The thalweg doctrine has been applied in principle in navigable rivers, and also in a few territorial sea boundaries, where international navigation was the prime interest.

146 Despite the separation between Georges Bank and Browns Bank on the surface along the Northeast Channel, the precoastal-plain history of Georges Bank and the Gulf of Maine is inferred to be similar to that of coastal New England and Nova Scotia. During Cretaceous, Tertiary, and possibly Jurassic times, the deposition of coastal-plain sediments took place, resulting eventually in a sedimentary wedge 3 to 9 kilometers thick. It was mainly during the Pliocene epoch that a major episode of subarial exposure and erosion took place, which formed the general shape of the present Gulf of Maine. Streams eroded the inner part of the coastal-plain wedge, forming an interior lowland in the Gulf of Maine, and carving Georges Bank into its cuesta form. The Northeast Channel and the Great Southeast Channel were the water gaps for streams draining the interior lowland. However, in the subsequent Pleistocene epoch, continental glaciers eventually advanced across the interior lowland and as far as the northern edge of Georges Bank. During the glacial movement, submarine slump or landslides occurred along the northern slope of Georges Bank, depositing outwash materials in the Northeast Channel. Later, Georges Bank was submerged by the postglacial rise in sea level. See generally Austin, et al., Geology of New England Passive Margin, 64 Am. A. Pet. Geol. Bull. 501 (1980); Ballard, & Ellis, , Continental Slope and the Upper Rise off Western Nova Scotia and Georges Bank, 61 id. 1483 (1977)Google Scholar; Ballard, & Sørensen, , The Preglacial Structure of Georges Bank and the Northeast Channel, Gulf of Maine, 52 id. 494 (1968)Google Scholar; Emery, & Uchupi, , The Structure of Georges Bank, 3 Marine Ecology 349 (1965)Google Scholar; Oldale, , Geophysical Observations on the Northern Parts of Georges Bank and Adjacent Basins in the Gulf of Maine, 58 Am.

163 As to the applicability of the principle of natural prolongation, see text at notes 149–53 supra. The unity of deposits, though the very object of the legal regime of the maritime extension, is not in itself a principle or a criterion of delimitation; it is not anything more than “a factual element which it is reasonable to take into account in the course of the negotiations for a delimitation.” See [1969] ICJ Rep. 3, para. 97.The problem of a common deposit straddling a boundary was once regarded as a hard-core issue, but now it is resolved one way or another by the development of the method of unitization. In the joint report of Oct. 15, 1977, the United States and Canada already agreed in principle on the unitization plan by establishing a shared access zone in the boundary area.

177 In the U.S. Senate hearings, several senators and panelists said informally that the maritime boundary matter might be settled on the principle of splitting the difference. See, e.g., 1980 Senate Hearings, supra note 43, at 98 (remarks of Senator Muskie and Mr. D. Bergson).

178 A question will arise as to whether the Court is precluded from giving such an area to the United States, solely because it has been claimed only by Canada. The answer seems to be negative. Such a delimitation would not necessarily mean an unfair decision giving a party more than it claims, because in this case each party is competing on the basis of legal principles rather than over any title to the submerged land. In the delimitation by lex propria motu, particularly owing to the inappropriate claims by the parties, the Court should be allowed to employ any legitimate method or methods it deems proper.

184 See, e.g., continental shelf delimitation between France and Spain, UN Doc. ST/LEG/ SER.B/19, at 445–50 (1980). The doctrine of proportionality was respected in the recent decision by the Assistant Administrator for Coastal Zone Management, National Oceanic and Atmospheric Administration (NOAA), with respect to the interstate continental shelf boundary dispute between Mississippi and Louisiana. In accordance with the Coastal Energy Impact Program, under section 308 of the Coastal Zone Management Act of 1972, Pub. L. No. 92–583, §308, 86 Stat. 1280 (1972), as amended by section 7 of the Coastal Zone Management Act Amendments of 1976, Pub. L. No. 94–370, 90 Stat. 1013 (1976) (codified at 16 U.S.C. §1456a (1979)), and section 5 of the Outer Continental Shelf Lands Act Amendments of 1978, Pub. L. No. 95–372, 92 Stat. 629, 43 U.S.C. §§1801 et seq., the Assistant Administrator established the lateral boundary line in 1979 by halving the distance between the eastern coastline of Louisiana and an equidistance line between the two coasts, so that the boundary line would divide the area in accordance with the ratio of the relative lengths of the two coastlines. See Robert W. Knecht, Assistant Administrator for Coastal Zone Management, NOAA, U.S. Dep’t of Commerce, Establishment of the Mississippi/Louisiana Coastal Energy Impact Program Delimitation Line (1979). Both states challenged the decision and filed court suits. See State of Mississippi v. Secretary, U.S. Dep’t of Commerce, et al., Civil Action File No. J79–0634(R) (S.D.

189 This does not necessarily mean that the equidistance method should be applied to the entire “inner area.” It is desirable that the equidistance line be turned oceanward somewhere in the central area of the Gulf before it “protrudes” into the “outer area.” The division between the “inner area” and the “outer area” is relative in the particular situation. There may be a blurred area between the two. This division, which would generally coincide with that between “opposite” and “adjacent” situations, would be useful particularly in the bay or Gulf area where the “opposite” situation is mixed with the “adjacent” in varying degrees. This concurrent method was used in the Grisbadarna arbitration. The tribunal employed the median line method in the “inner area” and the line perpendicular to the general direction of the coast in the “outer area.” See note 173 supra, passim.

190 It appears that the line claimed by the United States in the north does not represent the main channel of navigation between the two countries. The thalweg doctrine or the mid-channel principle was originally propounded for the mutual preservation of the equal right and access of navigation mostly in navigable rivers. See note 145 supra. It is therefore unreasonable to apply the mid-channel principle to the northern corner of the Gulf where there is, as a matter of fact, no main channel of navigation.

191 It is expected that it will take at least 3 years from the time of die exchange of ratification instruments of the Boundary Settlement Treaty to die final determination of the boundary by die Court. In the North Sea Continental Shelf cases, it took about 2 years: dip special agreement entered into force on Feb. 2, 1967, and the ICJ rendered its judgment on Feb. 20, 1969. In the Anglo-French Continental Shelf arbitration, it also took about 2 years: the arbitration agreement entered into force on July 10, 1975, and the court of arbitration rendered its decision on June 30, 1977. As to the likely length of die proceedings relating to the United States-Canadian maritime boundary delimitation in the Gulf of Maine area, Professor L. B. Sohn observed:

Considering the possible extension of lime limits in preparing for briefs, he concluded diat it would take at least 3 years. See letter from Professor L. B. Sohn to Senator E. M. Kennedy, Sept. 20, 1979, reprinted in 1980 Senate Hearings, supra note 43, at 104–05.

192 This is the author’s tentative denomination. A unitization plan was originally propounded for the cooperative division of the common pool of oil and gas deposits straddling the boundary in order to avoid die economic waste resulting from competitive drilling between neighbors. This method has also been suggested as applicable mutatis mutandis in the allocation of underground waters. See, e.g., Trelease, , Legal Solutions to Groundwater Problems—A General Overview, 11 Pacific L.J. 863, 868–69 (1980)Google Scholar. By the same token, it is desirable that the unitization method be utilized for the efficient management of fishery resources between states. For the economic value of die cooperative management of common resources, see, e.g., Friedman, A. E., The Economics of the Common Pool: Property Rights in Exhaustible Resources, 18 UCLA L. Rev. 885 (1971)Google Scholar.
