Chukchi Sea in the context of "Alaska"

Beringia is a prehistoric geographical region, defined as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka peninsulas in Russia as well as Alaska in the United States and Yukon in Canada.

The area includes land lying on the North American Plate and Siberian land east of the Chersky Range. At various times, it formed a land bridge referred to as the Bering land bridge or the Bering Strait land bridge that was up to 1,000 km (620 mi) wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling about 1.6 million km (620,000 sq mi), allowing biological dispersal to occur between Asia and North America. Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St. Paul and St. George, St. Lawrence Island, St. Matthew Island, and King Island.

The Bering Sea (/ˈbɛərɪŋ, ˈbɛrɪŋ/ BAIR-ing, BERR-ing, US also /ˈbɪərɪŋ/ BEER-ing; Russian: Бе́рингово мо́ре, romanized: Béringovo móre, IPA: [ˈbʲerʲɪnɡəvə ˈmorʲe]) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and the Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves. The Bering Sea is named after Vitus Bering, a Danish-born Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean.

The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over 2,000,000 square kilometers (770,000 sq mi) and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Bering Sea to the Arctic Ocean's Chukchi Sea. Bristol Bay is the portion of the Bering Sea between the Alaska Peninsula and Cape Newenham on mainland Southwest Alaska.

The Seward Peninsula is a large peninsula on the western coast of the U.S. state of Alaska whose westernmost point is Cape Prince of Wales. The peninsula projects about 200 mi (320 km) into the Bering Sea between Norton Sound, the Bering Strait, the Chukchi Sea, and Kotzebue Sound, just below the Arctic Circle. The entire peninsula is about 210 mi (330 km) long and 90–140 mi (145–225 km) wide. Like Seward, Alaska, it was named after William H. Seward, the United States Secretary of State who fought for the U.S. purchase of Alaska.

The Seward Peninsula is a remnant of the Bering land bridge, a roughly thousand-mile-wide swath of land connecting Siberia with mainland Alaska during the Pleistocene Ice Age. This land bridge aided in the migration of humans, as well as plant and animal species, from Asia to North America. Excavations at sites such as the Trail Creek Caves and Cape Espenberg in the Bering Land Bridge National Preserve as well as Cape Denbigh to the south have provided insight into the timeline of prehistorical migrations from Asia to the Seward Peninsula.

Chukotsky District (Russian: Чуко́тский райо́н, Čukótskiy rayón; Chukchi: Чукоткакэн район, Čukotkakèn rajon) is an administrative and municipal district (raion), one of the six in Chukotka Autonomous Okrug, Russia. It is the easternmost district of the autonomous okrug and Russia, and the closest part of Russia to the United States. It borders with the Chukchi Sea in the north, the Bering Sea in the east, Providensky District in the south, and the Kolyuchinskaya Bay in the west. The area of the district is 30,700 square kilometers (11,900 sq mi). Its administrative center is the rural locality (a selo) of Lavrentiya. Population: 4,995 (2021 census); 4,838 (2010 census); 4,541 (2002 census); 6,878 (1989 Soviet census). The population of Lavrentiya accounts for 30.2% of the district's total population.

The district is populated mainly by indigenous peoples, the majority being either Chukchi or Yupik. The sparse nature of the population means that this is the only district in the autonomous okrug without any urban localities. The selo of Uelen is located in the district, which is a focal point for indigenous artwork of the region as a whole and the birthplace of Yuri Rytkheu, the first internationally recognized Chukchi writer.

The Chukchi, or Chukchee (Chukot: ԓыгъоравэтԓьэт, о'равэтԓьэт, ḷygʺoravètḷʹèt, o'ravètḷʹèt), are a Siberian ethnic group native to the Chukchi Peninsula, the shores of the Chukchi Sea and the Bering Sea region of the Arctic Ocean all within modern Russia. They speak the Chukchi language. The Chukchi originated from the people living around the Okhotsk Sea.

According to several studies on genomic research conducted from 2014 to 2018, the Chukchi are the closest Asian relatives of the indigenous peoples of the Americas, as such they are descendants of the settlers of Beringia who remained on the Russian side when the sea levels rose.

Uelen is a rural locality (a selo) in Chukotsky District, just south of the Arctic Circle in Chukotka Autonomous Okrug in the Russian Far East. As of the 2010 Census, its population was 720. Located near Cape Dezhnev where the Bering Sea meets the Chukchi Sea, it is the easternmost settlement in Russia and the whole of Asia. It is located in the Western Hemisphere, but the International Date Line curves around it, so it remains in a Russian time zone (UTC+12:00). Uelen is also the closest Asian settlement to North America. It is on the northeast corner of the Uelen Lagoon, a roughly 15 by 3 kilometres (9 by 2 miles) east-west lagoon separated from the ocean by a sandspit. Municipally, Uelen is subordinated to Chukotsky Municipal District and is incorporated as Uelen Rural Settlement.
