Features, limits and zones

Maritime boundary is a conceptual means of division of the water surface of the planet into maritime areas that are defined through surrounding physical geography or by human geography. As such it usually includes areas of exclusive national rights over the mineral and biological resources,[1] encompassing maritime features, limits and zones.[2] Although in some countries the term maritime boundary represent borders of a maritime nation[3] and are recognized by the United Nations Convention on the Law of the Sea, they usually serve to identify international waters.

Maritime boundaries exist in the context of territorial waters, contiguous zones, and exclusive economic zones; however, the terminology does not encompass lake or river boundaries, which are considered within the context of land boundaries.

Some maritime boundaries have remained indeterminate despite efforts to clarify them. This is explained by an array of factors, some of which illustrate regional problems.[4]

The delineation of maritime boundaries has strategic, economic and environmental implications.[5]

Terminology

The terms boundary, frontier and border are often used as if they were interchangeable, but they are also terms with precise meanings.[6]

A boundary is a line. The terms "frontier", "borderland" and "border are zones of indeterminate width. Such areas forms the outermost part of a country. Borders are bounded on one side by a national boundary.[7] There are variations in the specific terminology of maritime boundary agreements which have been concluded since the 1970s. Such differences are less important than what is being delimited.[8]

Features

Features which affect maritime boundaries include islands and the submerged seabed of the continental shelf.[2]

The process of boundary delimitation in the ocean encompasses the natural prolongation of geological features and outlying territory. The process of establishing "positional" borders encompasses the distinction between previously resolved and never-resolved controversies.[9]

Limits

The limits of maritime boundaries are expressed in polylines and in polygon layers of sovereignty and control,[10] calculated from the declaration of a baseline. The conditions under which a state may establish such baseline are described in the United Nations Convention on the Law of the Sea (UNCLOS). A baseline of a country can be the low water line, a straight baseline (a line that encloses bays, estuaries, inland waters,...) or a combination of the two.[1]

For example, in the map at the right which shows Australian Arctic Territorial (AAT) maritime zones, the Adélie Land or French territorial claim to Antarctica is indicated as a break the AAT waters. This portion of the Antarctic coast between 136° E and 142° E has a shore length of 350 km and associated maritime zones which are not recognized by all governments.

Zones

The zones of maritime boundaries are expressed in concentric limits surrounding coastal and feature baselines.[1]

  • Coastal waters—the zone extending 3 nm. from the baseline.[2]
  • Territorial sea—the zone extending 12 nm. from the baseline.[2]
  • Contiguous zone—the area extending 24 nm. from the baseline.[2]
  • Exclusive Economic Zone—the area extending 200 nm. from the baseline except when the space between two countries is less than 400 nm.[2]

In the case of overlapping zones, the boundary is presumed to conform to the equidistance principle or it is explicitly described in a multilateral treaty.[1]

Contemporary negotiations have produced tripoint and quadripoint determinations. For example, the 1982 Australia–France Marine Delimitation Agreement, it was assumed that France has sovereignty over Matthew and Hunter Islands, a territory that is also claimed by Vanuatu. The northernmost point in the boundary is a tripoint with the Solomon Islands. The boundary runs in a roughly north–south direction and then turns and runs west–east until it almost reaches the 170th meridian east.[11] The effect of these negotiated specifics is reflected in the map of Australian maritime zones at the right.

History

The concept of maritime boundaries is a relative new concept.[1] The historical record is a backdrop for evaluating border issues.[12] The evaluation of historic rights are governed by distinct legal regimes in customary international law, including research and analysis based on

The study of treaties on maritime boundaries is important as (a) as a source of general or particular international law; (b) as evidence of existing customary law; and (c) as evidence of the emerging development of custom.[14] The development of "customary law" affects all nations.

The attention accorded this subject has evolved beyond formerly-conventional norms like the three-mile limit.

Treaties

Multilateral treaties and documents describing the baselines of countries can be found on the website of the United Nations.[1]

For example, the Australia–France Marine Delimitation Agreement establishes ocean boundaries between Australia and New Caledonia in the Coral Sea (including the boundary between Australia's Norfolk Island and New Caledonia). It consists of 21 straight-line maritime segments defined by 22 individual coordinate points forming a modified equidistant line between the two territories.[11] The effect of this treaty is incorporated in the map of Australian maritime zones at the right.

Disputes

Controversies about territorial waters tend to encompass two dimensions: (a) territorial sovereignty, which are a legacy of history; and (b) relevant jurisdictional rights and interests in maritime boundaries, which are mainly due to differing interpretations of the law of the sea.[15]

Many disputes have been resolved through negotiations,[16] but not all.

Unresolved maritime boundaries

The disputed maritime border between North and South Korea in the West Sea:[17]
     A: United Nations-created Northern Limit Line, 1953[18]
     B: North Korea-declared "Inter-Korean MDL in the Yellow Sea", 1999[19]
The locations of specific islands are reflected in the configuration of each maritime boundary, including
1–Yeonpyeong Island
2–Baengnyeong Island
3–Daecheong Island

Among the array of unsettled disputes, the maritime borders of the two Koreas in the Yellow Sea represent a visuallly stark contrast.[17]

A western line of military control between the two Koreas was unilaterally established by the United Nations Command in 1953.[20][21] Although the North asserts a differently configured boundary line, there is no dispute that a few small islands close to the North Korean coastline have remained jurisdiction of the United Nations since 1953.[22]

The map at the right shows the differing maritime boundary lines of the two Koreas. The ambits of these boundaries encompass overlapping jurisdictional claims.[23] The explicit differences in the way the boundary lines are configured is shown in the map at the right.

In a very small area, this represents a unique illustration of differences in mapping and delineation strategies.

  • On one hand, the United Nations-created boundary line ("A") reflects the geographic features of the coastal baseline.[18]
  • On the other hand, while the North Korean-declared boundary line does acknowledges specific non-DPKR island enclaves, its "Military Demarcation Line" in the ocean ("B") is essentially a straight line.[19]

Violent clashes in these disputed waters include what are known as the first Yeonpyeong incident, the second Yeonpyeong incident, and the Bombardment of Yeonpyeong.[24]
