The Arctic deep-water basin, a constituent of the Arctic Ocean, is located beyond the shelf and occupies the continental slope, foothill, and abyssal part. It comprises two deep basins (Eurasia and Amerasia). The Norwegian-Greenland and Baffin basins, members of the Arctic Ocean, are usually excluded from the Arctic Basin. As a whole, the Arctic Ocean has been long considered a vast petroliferous basin (superbasin). Recently, the main prospects for the hydrocarbon resources are believed to be related to shelf margins of the ocean, where numerous oil and gas deposits were discovered (Barents, Pechora, and Kara seas in Russia; Beaufort Sea and delta of the Mackenzie River in Canada; northern Alaska in the United States). The geological-geophysical structure of the deep Arctic Basin surrounded by a spacious shelf has been poorly studied. Nevertheless, it is known that its hydrocarbon potential is significant.
