The Chukchi Sea is a part of the Arctic Ocean and is also known as the Chuuk Sea and the Sea of Chukotsk.
It is located off the northwestern Alaskan coast and is one of the world’s most productive marine ecosystems.
The sea is surrounded by Long Strait to the west, Point Barrow, Alaska, to the east, and the Bering Strait to the south.
The Chukchi Sea is saltier than other seas of the Arctic due to low runoff, and rivers such as the Kobuk, Noatak, and Amguema control its salinity level.
The sea is named after the Chukchi people, native Siberian people who lived on the Chukchi Peninsula and engaged in traditional fishing and hunting.
The Hope Basin is a significant geological feature of the Chukchi Sea, extending from the outward continental shelf of Seward Peninsula towards the coast of Chukotka.
Chukchi Sea hosts massive marine mammal migrations, with Beluga whales, bowhead whales, Pacific walrus, and bearded seals utilizing its shelf.
