context_page_description: Chukchi Sea, sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland.
context_section_description: The sea has an approximate area of 595,000 km² (230,000 sq mi) and is only navigable about four months of the year. The main geological feature of the Chukchi Sea bottom is the 700-kilometer-long (430 mi) Hope Basin, which is bound to the northeast by the Herald Arch. Depths less than 50 meters (160 ft) occupy 56% of the total area.
  The Chukchi Sea has very few islands compared to other seas of the Arctic. Wrangel Island lies at the northwestern limit of the sea, Herald Island is located off Wrangel Island's Waring Point, near the northern limit of the sea. A few small islands lie along the Siberian and Alaskan coasts.
  The sea is named after the Chukchi people, who reside on its shores and on the Chukotka Peninsula. The coastal Chukchi traditionally engaged in fishing, whaling and the hunting of walrus in this cold sea.
  In Siberia places along the coast are: Cape Billings, Cape Schmidt, Amguyema River, Cape Vankarem, the large Kolyuchinskaya Bay, Neskynpil'gyn Lagoon, Cape Serdtse-Kamen, Enurmino, Chegitun River, Inchoun, Uelen and Cape Dezhnev.
  In Alaska, the rivers flowing into the Chukchi Sea are the Kivalina, the Kobuk, the Kokolik, the Kukpowruk, the Kukpuk, the Noatak, the Utukok, the Pitmegea, and the Wulik, among others. Of rivers flowing in from its Siberian side, the Amguyema, Ioniveyem, and the Chegitun are the most important.
