BARENTS SEA

Speciality

The Barents Sea is a marginal sea of the Arctic Ocean, located north of Norway and Russia. Known in the Middle Ages as the Murman Sea, the sea takes its current name from the Dutch navigator Willem Barents.The Barents Sea (Norwegian: Barentshavet; Russian: Баренцево море, Barentsevo More) is a marginal sea of the Arctic Ocean, located north of Norway and Russia. Known in the Middle Ages as the Murman Sea, the sea takes its current name from the Dutch navigator Willem Barents. It is a rather deep shelf sea (average depth 760 feet (230 m) and maximum depth 1,480 feet (450 m)), bordered by the shelf edge towards the Norwegian Sea in the west, the islands of Svalbard (Norway) in the northwest, and the islands of Franz Josef Land and Novaya Zemlya (Arkhangelsk Oblast) in the northeast and east. Novaya Zemlya separates the Kara Sea from the Barents Sea. Significant fossil fuel energy resources exist in the Barents Sea region.

Geography

The southern half of the Barents Sea, including the ports of Murmansk (Russia) and Vardø (Norway) remain ice-free year round due to the warm North Atlantic drift. In September, the entire Barents Sea is more or less completely ice-free. Until the Winter War (1939–40), Finland's territory also reached to the Barents Sea, with the harbor at Petsamo being Finland's only ice-free winter harbor.There are three main types of water masses in the Barents Sea: Warm, salty Atlantic water (temperature >3°C, salinity >35) from the North Atlantic drift, cold Arctic water (temperature <0°C, salinity <35) from the north, and warm, but not very salty coastal water (temperature >3°C, salinity <34.7). Between the Atlantic and Polar waters, a front called the Polar Front is formed. In the western parts of the sea (close to Bear Island), this front is determined by the bottom topography and is therefore relatively sharp and stable from year to year, while in the east (towards Novaya Zemlya), it can be quite diffuse and its position can vary a lot between years.

History

The Barents Sea was formerly known to Russians as Murmanskoye Morye, or the "Sea of Murmans" (i.e., Norwegians), and it appears with this name in sixteenth-century maps, including Gerard Mercator's Map of the Arctic published in his 1595 atlas. Its eastern corner, in the region of the Pechora River's estuary, has been known as Pechorskoye Morye, that is, Pechora Sea.This sea was given its present name in honor of Willem Barents, a Dutch navigator and explorer. Barents was the leader of early expeditions to the far north, at the end of the sixteenth century. Seabed mapping was completed in 1933 with the first full map produced by Russian marine geologist Maria Klenova.The Barents Sea was also the site of a notable World War II engagement, a German surface merchant raiding attack on a British convoy that later became known as the Battle of the Barents Sea. Under the command of Oskar Kummetz, the German warships sank minelayer HMS Bramble and destroyer HMS Achates (H12), but in turn lost destroyer Z16 Friedrich Eckoldt and Admiral Hipper was severely damaged by British gunfire. The Germans later retreated and the British convoy arrived safely at
