continentaal plat		   volgens het internationale zeerecht, het verdragsmatig vastgelegde gebied van de zeebodem, dat zich onder water vanaf de kust uitstrekt in zee, of - vereenvoudigd gesproken - het gebied tot aan de continentale drempel, waar de zeebodem abrupt dieper wordt, of tot een afstand van 200 zeemijlen uit de kust. Men onderscheidt een 'geografisch' continentaal plat en een plat volgens internationaal recht. Dit is belangrijk wanneer het gaat om aanspraken op mijnbouwrechten, op de bodem en onder de grond.
geografisch/geologisch de door de oceaan omspoelde rand van het continent, dat vlak afhelt naar de sterkere continentale helling en tot minstens 200 m diepte gaat. Morfologisch gezien gaat het continentaal plat tot aan de shelfrand, waarvan de gemiddelde diepte bij 133 m ligt, maar zwenkt tussen 20 m en 550 m.

Kontinentalschelf
Schelf 		entsprechend dem internationalen Seerecht das durch Konvention festgelegte Gebiet des Meeresbodens, das sich unter Wasser von der Küste ins Meer erstreckt und zwar - sehr vereinfacht gesprochen - entweder bis zur Kontinentalschwelle, bei welcher der Meeresboden abrupt absinkt oder bis zu einer Entfernung von 200 Seemeilen von der Küste. Man unterscheidet zwischen einem 'geographischen' und einem 'rechtlichen' Schelf. Dieser ist von Bedeutung, wenn es um die Besitzansprüche bzw. die Abbaurechte an Rohstoffen auf dem Boden und unter der Erde geht.
geographisch/geologisch der vom Meer überspülter Rand des Kontinents, der flach zum stärker geneigten Kontinentalabhang abfällt und meistens bis zu 200m Tiefe gerechnet wird. Morphologisch geht der Schelf bis zur Schelfkante, deren mittlere Tiefe bei 133 m liegt, aber zwischen 20m und 550m schwankt.
en continental shelf

geologically and according to international maritime law the extended perimeter of a continent, covered by shallow seas or gulfs, either ending at the shelf break, or 200 sm from the coast. The legal definition of the shelf is of importance when it comes to the exploration and exploitation of subsoil resources (oil drilling, mining).

Article 76

1. The continental shelf of a coastal State comprises the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance.

2. The continental shelf of a coastal State shall not extend beyond the limits provided for in paragraphs 4 to 6.

3. The continental margin comprises the submerged prolongation of the land mass of the coastal State, and consists of the seabed and subsoil of the shelf, the slope and the rise. It does not include the deep ocean floor with its oceanic ridges or the subsoil thereof.

4. (a) For the purposes of this Convention, the coastal State shall establish the outer edge of the continental margin wherever the margin extends beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured, by either:

(i) a line delineated in accordance with paragraph 7 by reference to the outermost fixed points at each of which the thickness of sedimentary rocks is at least 1 per cent of the shortest distance from such point to the foot of the continental slope; or

(ii) a line delineated in accordance with paragraph 7 by reference to fixed points not more than 60 nautical miles from the foot of the continental slope.

(b) In the absence of evidence to the contrary, the foot of the continental slope shall be determined as the point of maximum change in the gradient at its base.

5. The fixed points comprising the line of the outer limits of the continental shelf on the seabed, drawn in accordance with paragraph 4 (a)(i) and (ii), either shall not exceed 350 nautical miles from the baselines from which the breadth of the territorial sea is measured or shall not exceed 100 nautical miles from the 2,500 metre isobath, which is a line connecting the depth of 2,500 metres.

6. Notwithstanding the provisions of paragraph 5, on submarine ridges, the outer limit of the continental shelf shall not exceed 350 nautical miles from the baselines from which the breadth of the territorial sea is measured. This paragraph does not apply to submarine elevations that are natural components of the continental margin, such as its plateaux, rises, caps, banks and spurs.

7. The coastal State shall delineate the outer limits of its continental shelf, where that shelf extends beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured, by straight lines not exceeding 60 nautical miles in length, connecting fixed points, defined by coordinates of latitude and longitude.

8. Information on the limits of the continental shelf beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured shall be submitted by the coastal State to the Commission on the Limits of the Continental Shelf set up under Annex II on the basis of equitable geographical representation. The Commission shall make recommendations to coastal States on matters related to the establishment of the outer limits of their continental shelf. The limits of the shelf established by a coastal State on the basis of these recommendations shall be final and binding.

9. The coastal State shall deposit with the Secretary-General of the United Nations charts and relevant information, including geodetic data, permanently describing the outer limits of its continental shelf. The Secretary-General shall give due publicity thereto.

10. The provisions of this article are without prejudice to the question of delimitation of the continental shelf between States with opposite or adjacent coasts.
