Chukchi Sea - Geography

Geography

The sea has an approximate area of 595,000 km² (230,000 mi²) and is only navigable about four months of the year. The main geological feature of the Chukchi Sea bottom is the 700 km (435 mi)-long Hope Basin, which is bound to the northeast by the Herald Arch. Depths less than 50 m (164 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 near its northern limit, and 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.

Famous quotes containing the word geography:

    At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.
    Derek Wall (b. 1965)

    Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.
    Ralph Waldo Emerson (1803–1882)

    The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.
    Willard Van Orman Quine (b. 1908)
