The Siberian Shelf, one of the Arctic shelves,
is the largest continental shelf of the Earth, a part of the continental shelf of
Russia. It extends from the continent of Eurasia in the general area of North Siberia (hence the name) into
the Arctic Ocean.
It stretches to 1500 kilometers (930 miles) offshore. It is relatively shallow, with
average depth of 100 m. A number of islands are within the shelf,
including the Wrangel Island, Novaya Zemlya, and the New
Siberian Islands. 
It is encompassed by the Kara Sea, Laptev Sea, and East Siberian Sea, and respectively
subdivided into the Kara Sea Shelf, Laptev
Sea Shelf, and East Siberian Shelf.
Eastwards it merges into the Chukchi Shelf (of the Chukchi Sea) shared by
Eurasia and Alaska (i.e., by
Russia and the United States).
Westwards it merges into the Barents Shelf of the Barents Sea.
Also, the New Siberian Islands and the New
Siberian Rift Basin define the New Siberian
According to the split of the high Arctic by the Lomonosov mid-ocean ridge
into the Eurasian
Basin and Amerasian Basin, the Siberian Shelf is
split between the Eurasian Shelf and the Amerasian Shelf.
The Siberian Shelf is the habitat for numerous flora and fauna.
Notably the Polar bear
is found through much of the shelf, including the Barents Sea and Chukchi Sea.
