The principal port on the Chukchi Sea is Uelen.
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 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.
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. Concerning the rivers that flow into the Chukchi Sea on its Siberian side, the Amguyema, Ioniveyem and the Chegitun are the most important.
The Chukchi sea has very few islands compared to other seas of the Arctic. There are no islands in its midst and only a small number of islands lie along the Siberian coast.
In 1913, the Karluk, abandoned by expedition leader Vilhjalmur Stefansson, drifted in the ice along the northern expanses of the Chukchi Sea and sank crushed by ice near Herald Island. The survivors made it to Wrangel Island where they found themselves in a hopeless situation. Then Captain Robert Bartlett walked hundreds of kilometers with Kataktovik, an Inuit man, on the ice of the Chukchi Sea in order to look for help. They reached Cape Vankarem on the Chukotka coast, on April 15th 1914. Twelve survivors of the ill-fated expedition were found on Wrangel island nine months later by the King & Winge, a newly-built Arctic fishing schooner.
In 1933, the steamer Chelyuskin sailed from Murmansk, east bound to attempt a transit of the Northern Sea Route to the Pacific, in order to demonstrate that such a transit could be achieved in one season. The vessel became beset in heavy ice in the Chukchi Sea, and after drifting with the ice for over two months, was crushed and sank on 13 February 1934 near Kolyuchin Island. Apart from one fatality, her entire complement of 104 people was able to establish a camp on the sea ice. The Soviet government organised an impressive aerial evacuation, under which all were rescued. Captain Vladimir Voronin and expedition leader Otto Schmidt became heroes.
Following several unsuccessful attempts, the wreck was located on the bed of the Chukchi Sea by a Russian expedition, Chelyuskin-70, in mid-September 2006. Two small components of the ship's superstructure were recovered by divers and were sent to the ship's builders, Burmeister & Wain of Copenhagen, for identification.
