The Sea of Okhotsk (Russian: Охо́тское мо́ре, tr. Okhótskoye móre, IPA: [ɐˈxot͡skəjə ˈmorʲe]; Japanese: オホーツク海, translit. Ohōtsuku-kai) is a marginal sea of the western Pacific Ocean,[1] between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaido to the south, the island of Sakhalin along the west, and a long stretch of eastern Siberian coast along the west and north. The northeast corner is the Shelikhov Gulf. The sea is named after Okhotsk, the first Russian settlement in the Far East.

Geography
Shiretoko National Park on the Sea of Okhotsk coast of Hokkaido, Japan
The Sea of Okhotsk covers an area of 1,583,000 square kilometres (611,000 sq mi), with a mean depth of 859 metres (2,818 ft) and a maximum depth of 3,372 metres (11,063 ft). It is connected to the Sea of Japan on either side of Sakhalin: on the west through the Sakhalin Gulf and the Gulf of Tartary; on the south, through the La Pérouse Strait.
In winter, navigation on much of the Sea of Okhotsk becomes difficult or impossible due to the formation of large ice floes, because the large amount of freshwater from the Amur River lowers the salinity of upper levels often raising the freezing point of the sea surface. The distribution and thickness of ice floes depends on many factors: the location, the time of year, water currents, and the sea temperatures.
Depths
With the exception of Hokkaido, one of the Japanese home islands, the sea is surrounded on all sides by territory administered by the Russian Federation.
Extent
The International Hydrographic Organization defines the limits of the Sea of Okhotsk as follows:[2]
On the Southwest. The Northeastern and Northern limits on the Japan Sea [In La Perouse Strait (Sôya Kaikyô). A line joining Sôni Misaki and Nishi Notoro Misaki (45°55'N). From Cape Tuik (51°45'N) to Cape Sushcheva].
On the Southeast. A line running from Nosyappu Saki (Cape Noshap, 43°23'N) in the Island of Hokusyû (Yezo) through the Kuril or Tisima Islands to Cape Lopatka (South point of Kamchatka) in such a way that all the narrow waters between Hokusyû and Kamchatka are included in the Sea of Okhotsk.
Islands
Some of the Sea of Okhotsk's islands are quite large, including Japan's second largest island, Hokkaido, as well as Russia's largest island, Sakhalin. Practically all of the sea's islands are either in coastal waters or belong to the various islands making up the Kuril Islands chain. These fall either under undisputed Japanese or Russian ownership or disputed ownership between Japan and Russia. Iony Island is the only island located in open waters and belongs to the Khabarovsk Krai of the Russian Federation. The majority of the sea's islands are uninhabited making them ideal breeding grounds for seals, sea lions, seabirds, and other sea island fauna. Large colonies, with over a million individuals, of crested auklets use the Sea of Okhotsk as a nesting site.
History
Most of the Sea of Okhotsk, with the exception of the Sakhalin Island, had been well mapped by 1792
Pre-modern
The Okhotsk culture is an archaeological coastal fishing and hunter-gatherer culture of the lands surrounding the Sea of Okhotsk (600–1000 CE in Hokkaido, until 1500 or 1600 CE in the Kurils).
Some believe that Mishihase was living in the area.
Exploration and settlement
Russian explorers Ivan Moskvitin and Vassili Poyarkov were the first Europeans to visit the Sea of Okhotsk (and, probably, the island of Sakhalin[3]) in the 1640s.
The Dutch captain Maarten Gerritsz Vries in the Breskens entered the Sea of Okhotsk from the south-east in 1643, and charted parts of the Sakhalin coast and Kurile Islands, but failed to realize that either Sakhalin or Hokkaido are islands.
The first and foremost Russian settlement on the shore was the port of Okhotsk, which relinquished commercial supremacy to Ayan in the 1840s. The Russian-American Company all but monopolized the commercial navigation of the sea in the first half of the 19th century.
The Second Kamchatka Expedition under Vitus Bering systematically mapped the entire coast of the sea, starting in 1733. Jean-François de La Pérouse and William Robert Broughton were the first non-Russian European navigators known to have passed through these waters other than Maarten Gerritsz Vries. Ivan Krusenstern explored the eastern coast of Sakhalin in 1805. Mamiya Rinzō and Gennady Nevelskoy determined that the Sakhalin was indeed an island separated from the mainland by a narrow strait. The first detailed summary of the hydrology of the Okhotsk sea was prepared and published by Stepan Makarov in 1894.
Fishing
The Sea of Okhotsk is one of the world's richest in biological resources, with various kinds of fish, shellfish and crabs.
The harsh conditions of crab fishing in the Sea of Okhotsk is the subject of the most famous novel of the Japanese writer Takiji Kobayashi, 'The Crab Cannery Ship' (1929).
Whaling
American and European whaleships hunted whales in the sea in the nineteenth and early twentieth centuries. They primarily caught right and bowhead whales. A number of ships were wrecked in the sea.[4][5][6][7][8][9]
Modern
During the Cold War, the Sea of Okhotsk was the scene of several successful U.S. Navy operations (including Operation Ivy Bells) to tap Soviet Navy undersea communications cables. These operations were documented in the book Blind Man's Bluff: The Untold Story of American Submarine Espionage. The sea (and surrounding area) were also the scene of the Soviet attack on Korean Air Flight 007 in 1983. The Soviet Pacific Fleet used the Sea as a ballistic missile submarine bastion,[10] a strategy that Russia continues.
In the Japanese language, the sea has no traditional Japanese name despite its close location to the Japanese territories and is called Ohōtsuku-kai (オホーツク海), which is a transcription of the Russian name. Additionally, Okhotsk Subprefecture, Hokkaidō which faces the sea, also known as Okhotsk region (オホーツク地方, Ohōtsuku-chihō), is named after the sea.
Oil and gas exploration
29 zones of possible oil and gas accumulation have been identified on the Sea of Okhotsk shelf, which runs along the coast. Total reserves are estimated at 3.5 billion tons of equivalent fuel, including 1.2 billion tons of oil and 1.5 billion cubic meters of gas.[11]
On 18 December 2011 the Russian oil drilling rig Kolskaya[12] capsized and sank in a storm in the Sea of Okhotsk, some 124 km from Sakhalin Island, where it was being towed from Kamchatka. Reportedly its pumps failed, causing it to take on water and sink. The platform carried 67 people, of which 14 were initially rescued by the icebreaker Magadan and the tugboat Natftogaz-55. The platform was subcontracted to a company working for the Russian energy giant Gazprom.[13][14][15]
