Continental shelf of Russia

The continental shelf of Russia (also called the Russian continental shelf or the Arctic shelf in the Arctic region) is a continental shelf adjacent to Russia. Geologically, the extent of the shelf is defined as the entirety of the continental shelves adjacent to Russia's coast. In international law, however, the United Nations Convention on the Law of the Sea more narrowly defines the extent of the shelf as the seabed and subsoil of the submarine areas over which a state exercises sovereign rights.

The Siberian Shelf in the Arctic Ocean is the largest (and least explored) of the Russian shelves, a region of strategic importance because of its oil and natural gas reserves. Other parts of the Russian shelf are typically named after the corresponding seas: Barents Shelf (Barents Sea Shelf), Chukchi Shelf (Chukchi Sea Shelf), etc. With the exception of internal Russian seas, these geological shelves are shared with other countries which share the corresponding seas. For example, the Chukchi Shelf is shared between Russia and the United States according to the 1990 USA-USSR maritime boundary.

On 20 December 2001, Russia made an official submission into the UN Commission on the Limits of the Continental Shelf in accordance with the United Nations Convention on the Law of the Sea (article 76, paragraph 8). In the document it is proposed to establish new outer limits of the continental shelf of Russia beyond the previous 200 nautical mile zone (370 km), but within the Russian Arctic sector. The territory claimed by Russia in the submission is a large portion of the Arctic within Russia's sector and extending to the North Pole. One of the arguments was a statement that eastern portion of the Lomonosov Ridge, an underwater mountain ridge extending across the polar basin, and the Mendeleev Ridge are extensions of the Eurasian continent. In 2002, the UN Commission requested that Russia submit additional scientific evidence in support of its claim.
