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 ...
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 ...
On 15 October 2010, Russian scientists opened a floating polar research station in the Chukchi Sea at the margin of the Arctic Ocean. The name of the station was Severny Polyus-38 and it was home to 15 researchers for a year. They conducted polar studies and gathered scientific evidence to reinforce Russia's claims to the Arctic.

The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans.
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.
Global mean sea levels (GMSL) rose by 3.66 mm (0.144 in) per year which is "2.5 times faster than the rate from 1900 to 1990". [7]: 2 [8] At the rate of acceleration, it "could reach around 30 cm (12 in) to 60 cm (24 in) by 2100 even if greenhouse gas emissions are sharply reduced and global warming is limited to well below 2 °C, but around 60 cm (24 in) to 110 cm (43 in) if emissions ...
The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Canada near Nova Scotia. Near Nova Scotia, this cold water current meets the warm northward moving Gulf Stream.
