The ridge divides the Arctic Basin into the Eurasian Basin and the Amerasian Basin. The width of the Lomonosov Ridge varies from 60 to 200 kilometres (37 to 124 mi). It rises 3,300 to 3,700 metres (10,800 to 12,100 ft) above the 4,200-metre (13,800 ft) deep seabed. The minimum depth of the ocean above the ridge is less than 400 metres (1,300 ft ...
The warming in the Fram Strait region has likely amplified Arctic shrinkage, and serves as a positive feedback mechanism for transporting more internal energy to the Arctic Ocean. [15] In the past century, the sea surface temperature at Fram Strait has on average warmed roughly 1.9 °C (3.5 °F), and is 1.4 °C (2.5 °F) warmer than during the ...
Four major water masses originating in the Atlantic and Arctic oceans meet in the Norwegian Sea, and the associated currents are of fundamental importance for the global climate. The warm, salty North Atlantic Current flows in from the Atlantic Ocean, and the colder and less saline Norwegian Current originates in the North
The Arctic Ocean Deep Water is approximately 34.92 psu. [1] This water mass has a higher salinity due to brine rejection in the Arctic Seas. The depth is around 1500 and 2000 meters. The Norwegian Sea Deep Water is a combination of the Arctic Ocean Deep Water and the Greenland Sea Deep Water. This water mass is found below 2000 meters. [8]
The Siberian Shelf is a coastal shelf in the Arctic Ocean and is the largest continental shelf of the Earth, a part of the continental shelf of Russia. It extends from the continent of Eurasia in the general area of North Siberia (hence the name) into the Arctic Ocean .
Warmer and saltier Atlantic water is extending its reach northward into the Arctic Ocean. [2] The Arctic Ocean is becoming warmer and saltier and sea-ice is disappearing as a result. [3] The process can be seen on the figure on the far right, where the sea surface temperature change in the past 50 years is shown, which is up to 5 degrees in ...
Map of the Arctic region showing the Northern Sea Route, in the context of the Northeast Passage, and Northwest Passage [1]. The Northern Sea Route (NSR) (Russian: Се́верный морско́й путь, romanized: Severnyy morskoy put, shortened to Севморпуть, Sevmorput) is a shipping route about 5,600 kilometres (3,500 mi) long.
Hudson Bay is often considered part of the Arctic Ocean: [8] the International Hydrographic Organization, in its 2002 working draft [9] of Limits of Oceans and Seas, defined Hudson Bay, with its outlet extending from 62.5 to 66.5 degrees north (just a few miles south of the Arctic Circle) as being part of the Arctic Ocean, specifically "Arctic ...
