About Sea of Okhotsk

Map of the Sea of Okhotsk.

The 'Sea of Okhotsk' (Russian: Охо́тское мо́ре; English Transliteration: ''Okhotskoye More'') is a part of the western Pacific Ocean, lying between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaidō to the far south, the island of Sakhalin along the west, and a long stretch of eastern Siberian coast (including the Shantar Islands) along the west and north. It is named after Okhotsk, the first Russian settlement in the Far East.

Geography


The Sea of Okhotsk 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 the Sea of Okhotsk becomes difficult, or even impossible, due to the formation of large ice floes, because the large amount of freshwater from the Amur lowers the salinity and raises the freezing point of the sea. The distribution and thickness of ice floes depends on many factors: the location, the time of year, water currents, and the sea temperatures.
With the exception of Hokkaidō, one of the Japanese Home Islands, the sea is surrounded on all sides by territory administered by the Russian Federation. For this reason, it is generally considered as being under Russian sovereignty.

Name and history


The Russian explorers Ivan Moskvitin and Vassili Poyarkov were the first Europeans to visit the Sea of Okhotsk and the island of Sakhalin in the 1640s. 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. La Pérouse and William Robert Broughton were the first non-Russian European navigators known to have passed through these waters. Ivan Krusenstern explored the eastern coast of the Sakhalin in 1805. Mamiya Rinzo 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 sea was prepared and published by Stepan Makarov in 1894.
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 ''. The sea (and surrounding area) were also the scene of the Soviet ''PVO Strany'' attack on Korean Air Flight 007 in 1983. The Soviet Pacific Fleet used the Sea as a ballistic missile submarine bastion, a strategy that Russia continues.
In the Japanese language, the sea was traditionally called ''Hokkai'' (北海), meaning 'north sea'. However, because this term is now used to refer to the North Sea in Europe, the name has changed to ''Ohōtsuku-kai'' (オホーツク海), a transcription of the Russian name.

Oil reserves


Twenty-nine 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[1].
