The Bering Strait (Russian : Берингов пролив) is a strait of the Pacific, which separates Russia and the United States slightly south of the Arctic Circle at about 65° 40' N latitude. The present Russia-US east–west boundary is at 168° 58' 37" W. The Strait is named after Vitus Bering, a Danish explorer in the service of the Russian Empire.


The Strait has been the subject of the scientific hypothesis that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels – perhaps a result of glaciers locking up vast amounts of water – exposed a wide stretch of the sea floor, [1] both at the present strait and in the shallow sea north and south of it. This view of how Paleo-Indians entered America has been the dominant one for several decades and continues to be the most accepted one. Numerous successful crossings without the use of a boat have also been recorded since at least the early 20th century.

Since 2012, the Russian coast of the Bering Strait has been a closed military zone. Through organized trips and the use of special permits, it is possible for foreigners to visit. All arrivals must be through an airport or a cruise port, near the Bering Strait only at Anadyr or Provideniya. Unauthorized travelers who arrive on shore after crossing the strait, even those with visas, may be arrested, imprisoned briefly, fined, deported and banned from future visas. [2]

Geography and science

The Bering Strait is about 82 kilometers (51 mi) wide at its narrowest point, between Cape Dezhnev, Chukchi Peninsula, Russia, the easternmost point (169° 39' W) of the Asian continent and Cape Prince of Wales, Alaska, United States, the westernmost point (168° 05' W) of the North American continent. It is 53 miles (85 km) wide, and at its deepest point is only 90 m (300 ft) in depth. [3] It borders the Chukchi Sea (part of the Arctic Ocean) to the north and the Bering Sea to the south.

The International Date Line runs equidistant between the Strait's Diomede Islands at a distance of 1.5 km (1 mi), leaving the Russian and American sides usually on different calendar days, with Cape Dezhnev 21 hours ahead of the American side (20 hours during daylight saving time).


The area is sparsely populated.

The eastern coast belongs to the U.S. state of Alaska. Notable towns on the American coast of the Strait include Nome (3,788 people) and the small settlement of Teller (228 people).

The western coast belongs to the Chukotka Autonomous Okrug, a federal subject of Russia. Major towns that lie along the Strait include Lorino (1,267 people) and Lavrentiya (1,459 people).

The Diomede Islands lie midway in the Strait. The village in Little Diomede has a school which belongs to Alaska's Bering Strait School District.

From at least 1562, European geographers thought that there was a Strait of Anián between Asia and North America. In 1648, Semyon Dezhnyov probably passed through the strait, but his report did not reach Europe. Danish-born Russian navigator Vitus Bering entered it in 1728. In 1732, Mikhail Gvozdev crossed it for the first time, from Asia to America. It was visited in 1778 by the third voyage of James Cook. Adolf Erik Nordenskiöld in 1878–79 sailed along the northern coast of Siberia, thereby proving that there was no northern land bridge from Asia to North America.

American vessels were hunting for bowhead whales in the strait by 1847. [4]

In March 1913, Captain Max Gottschalk (German) crossed from the east cape of Siberia to Shishmaref, Alaska, on dogsled via Little and Big Diomede islands. He was the first documented modern voyager to cross from Russia to North America without the use of a boat. [5]

In 1987, swimmer Lynne Cox swam a 4.3-kilometer (2.7 mi) course between the Diomede Islands from Alaska to the Soviet Union in 3.3 °C (37.9 °F) water during the last years of the Cold War. [6]

In June and July 1989, three independent teams attempted the first modern sea-kayak crossing of the Bering Strait. The groups were: seven Alaskans, who called their effort Paddling Into Tomorrow (i.e. crossing the international dateline); a four-man British expedition, Kayaks Across the Bering Strait; and a team of Californians in a three-person biadarka, led by Jim Noyes (who launched his ambitious expedition as a paraplegic). Accompanying the Californians was a film crew in a umiak, a walrus-skin boat traditional to the region; they were filming the 1991 documentary Curtain of Ice, directed by John Armstrong. [7] [8]

In 1998, Russian adventurer Dmitry Shparo and his son Matvey crossed the frozen Bering Strait on skis.

In March 2006, Briton Karl Bushby and French-American adventurer Dimitri Kieffer crossed the strait on foot, walking across a frozen 90-kilometer (56 mi) section in 15 days. [9] They were soon arrested for not entering Russia through a border control. [10]

August 2008 marked the first crossing of the Bering Strait using an amphibious road-going vehicle. The specially modified Land Rover Defender 110 was driven by Steve Burgess and Dan Evans across the straits on its second attempt following the interruption of the first by bad weather. [11]

In February 2012, a Korean team led by Hong Sung-Taek crossed the straits on foot in six days. They started from Chukotka Peninsula, the east coast of Russia on February 23 and arrived in Wales, the western coastal town in Alaska on February 29. [12]

In July 2012, six adventurers associated with "Dangerous Waters", a reality adventure show under production, made the crossing on Sea-Doos but were arrested and permitted to return to Alaska on their Sea-Doos after being briefly detained in Lavrentiya, administrative center of the Chukotsky District. They were treated well and given a tour of the village's museum, but not permitted to continue south along the Pacific coast. The men had visas but the western coast of the Bering Strait is a closed military zone. [2]

Between August 4 and 10 (US time), 2013, a team of 65 swimmers from 17 countries performed a relay swim across the Bering Strait, the first such swim in history. They swam from Cape Dezhnev, Russia, to Cape Prince of Wales, United States (roughly 110 kilometers (68 mi), due to the current). [13] [14] They had direct support from the Russian Navy, using one of its ships, and assistance with permission.

Proposed crossing

A physical link between Asia and North America via the Bering Strait nearly became a reality in 1864 when a Russian-American telegraph company began preparations for an overland telegraph line connecting Europe and America via the east. It was abandoned when the undersea Atlantic Cable proved successful. [15]

A further proposal for a bridge-and-tunnel link from Siberia to Alaska was made by French engineer Baron Loicq de Lobel in 1906. Czar Nicholas II of Russia issued an order authorising a Franco-American syndicate represented by de Lobel to begin work on the Trans-Siberian Alaska railroad project, but no physical work ever commenced. [16] [17] [18] [19] [20]

Suggestions have been made to construct a Bering Strait bridge between Alaska and Siberia. Despite the unprecedented engineering, political, and financial challenges, Russia green-lighted a US$65-billion TKM-World Link tunnel project in August 2011. If completed, the 103-kilometer (64 mi) tunnel will be the world's longest. [21] China considered construction of a "China-Russia-Canada-America" railroad line that would include construction of a 200-kilometer-long (120 mi) underwater tunnel that would cross the Bering Strait. [22]

Proposed dam

In 1956, the Soviet Union proposed to the US a joint bi-national project to warm the Arctic Ocean and melt some of the ice cap. As designed by Petr Borisov, the Soviet project called for a 90-kilometer-wide (56 mi) dam across the Bering Strait. It would block the cold Pacific current from entering the Arctic. By pumping low-salinity cold surface water across the dam to the Pacific, warmer and higher salinity sea water from the Atlantic Ocean would be introduced into the Arctic Ocean. [23] [24] [25] However, citing national security concerns, the CIA and FBI experts opposed the Soviet plan by arguing that while the plan was feasible, it would compromise NORAD and thus the dam could be built at only an immense cost. [26] Soviet scientist D. A. Drogaytsev also opposed the idea, stating that the sea north of the dam and north-flowing rivers in Siberia would become unnavigable year round, and the Gobi and other deserts would be extended to the northern Siberia coastline. [23]

American Charles P. Steinmetz earlier proposed to widen the Bering Strait by removing St. Lawrence Island and parts of Seward and Chukotski Peninsulas. A strait 320 kilometers (200 mi) wide would let the Japan Current melt the Arctic Ocean. [23]

In the 21st century a 300-kilometer (190 mi) dam has also been proposed, however the aim of the proposal is to preserve the Arctic ice cap against global warming. [27]

"Ice Curtain" border

During the Cold War, the Bering Strait marked the border between the Soviet Union and the United States. The Diomede IslandsBig Diomede (Russia) and Little Diomede (US)—are only 3.8 km (2.4 mi) apart. Traditionally, the indigenous peoples in the area had frequently crossed the border back and forth for "routine visits, seasonal festivals and subsistence trade", but were prevented from doing so during the Cold War. [28] The border became known as the "Ice Curtain". [29] It was completely closed, and there was no regular passenger air or boat traffic. In 1987, American swimmer Lynne Cox swam across the border, [30] and was congratulated jointly by American President Ronald Reagan and Soviet leader Mikhail Gorbachev.

Northwest Passage the Sea route north of North America

The Northwest Passage (NWP) is the sea route between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Canadian Arctic Archipelago. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP).

Bering Sea Sea of the northern Pacific Ocean off the coast of Alaska

The Bering Sea 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 for Vitus Bering, a Danish navigator in Russian service, who in 1728 was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean.

Cape Dezhnev Easternmost point of the Asian continent

Cape Dezhnyov or Cape Dezhnev, formerly known as East Cape or Cape Vostochny, is a cape that forms the easternmost mainland point of Asia. It is located on the Chukchi Peninsula in the very sparsely populated Chukotka Autonomous Okrug of Russia. This cape is located between the Chukchi Sea and the Bering Strait, 82 kilometres (51 mi) across from Cape Prince of Wales in Alaska; the Bering Strait is delimited by the two capes. The Diomede Islands and Fairway Rock are located in the midst of the strait.

Geography of the Soviet Union

The Geography of the Soviet Union includes the geographic features of countries of the former Union of Soviet Socialist Republics. The Soviet Union was the largest country in the world, covering approximately one-seventh of Earth's land surface. It was two and a half times the size of the United States, and only slightly smaller in land area than the entire continent of North America. It covered most of the northern half of Asia and a large part of Eastern Europe, extending even into the Middle East. About one-quarter of its territory was in Europe, and the rest in Asia. The territory of the USSR was dominated by the Russian Soviet Federative Socialist Republic—having the same borders as contemporary Russia—which covered roughly three-quarters of the surface area of the union.

Northeast Passage shipping lane from the Kara Sea to the Pacific Ocean

The Northeast Passage is, from the European and northern Atlantic point of view, the shipping route to the Pacific Ocean, along the Arctic coasts of Norway and Russia. The western route through the islands of Canada is accordingly called the Northwest Passage (NWP).

Semyon Ivanovich Dezhnev was a Russian explorer of Siberia and the first European to sail through the Bering Strait, 80 years before Vitus Bering did. In 1648 he sailed from the Kolyma River on the Arctic Ocean to the Anadyr River on the Pacific. His exploit was forgotten for almost a hundred years and Bering is usually given credit for discovering the strait that bears his name.

Big Diomede island

Big Diomede Island is the western island of the two Diomede Islands in the middle of the Bering Strait. The island is a part of the Chukotsky District of the Chukotka Autonomous Okrug of Russia. The border separating Russia and the United States runs north-south between the Diomede Islands.

Diomede Islands Islands between Alaska and Russia

The Diomede Islands, also known in Russia as Gvozdev Islands, consist of two rocky, mesa-like islands:

Little Diomede Island or “Yesterday Isle” is an island of Alaska, United States. It is the smaller of the two Diomede Islands located in the middle of the Bering Strait between the Alaska mainland and Siberia.

Chukchi Sea marginal sea of the Arctic Ocean north of the Bering Strait

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.

Cape Prince of Wales cape

Cape Prince of Wales is the westernmost mainland point of the Americas. It was named in 1778 by Captain James Cook of the British Royal Navy, presumably for the Prince of Wales at the time, George Augustus Frederick.

Seward Peninsula peninsula

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 320 kilometers (200 mi) 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 330 kilometers (210 mi) long and 145 km (90 mi)-225 km (140 mi) 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.

Bering Strait crossing Project of a railway tunnel between Russia and Alaska

A Bering Strait crossing is a hypothetical bridge or tunnel spanning the relatively narrow and shallow Bering Strait between the Chukotka Peninsula in Russia and the Seward Peninsula in the U.S. state of Alaska. The crossing would provide a connection linking North America and Eurasia.

The Bering Strait is the strait that connects the Arctic Ocean and the Bering Sea.

Dmitry Shparo is a Russian Arctic explorer and endurance skier. He is internationally known for twice reaching the North Pole on snow skis.

A fixed link or fixed crossing is a persistent, unbroken road or rail connection across water that uses some combination of bridges, tunnels, and causeways and does not involve intermittent connections such as drawbridges or ferries. A bridge–tunnel combination is commonly used for major fixed links.

Arctic exploration

Arctic exploration is the physical exploration of the Arctic region of the Earth. It refers to the historical period during which mankind has explored the region north of the Arctic Circle. Historical records suggest that humankind have explored the northern extremes since 325 BC, when the ancient Greek sailor Pytheas reached a frozen sea while attempting to find a source of the metal tin. Dangerous oceans and poor weather conditions often fetter explorers attempting to reach polar regions and journeying through these perils by sight, boat, and foot has proven difficult.

Naukan people

The Naukan, also known as the Naukanski, are a Siberian Yupik people and an indigenous people of Siberia. They live in the Chukotka Autonomous Region of eastern Russia.
