In contrast, no clear evolution was detected neither for sperm whale Physeter macrocephalus nor for Minke whale Balaenoptera acusrostrata. Citation: Joiris C R. Considerable increase in bowhead, blue, humpback and fin whales numbers in the Greenland Sea and Fram Strait between and   The extreme high pressure over the Barents Sea also led to a decrease in the air temperature.

To the southeast, the vast expanse Norwegian Sea lies behind the Jan Mayen Island, of which Greenland Sea may be considered an extension. In the summer the average air temperature is from 0C to 2C (4C in the South), and in the winter it reaches up to northern part of the sea is mostly covered with ice. ). In the Barents Sea, polar cod occur both in the areas of drifting sea ice in the northern Barents Sea and north of Svalbard (Lønne & Gulliksen ) and in the open water masses of the central and southern Barents Sea (Ajiad et al. ). In the Arctic, polar cod are often in areas with ice cover, but only part of the population is.

seas. The wintering distribution of the Ivory Gull is poorly known, although it generally winters along the southern edge of Arctic pack ice in the waters of the North Atlantic Ocean (Davis Strait and Labrador, Greenland and Barents seas), and the North Pacific Ocean (Bering Sea, Sea of Okhotsk, and perhaps the Beaufort and Chukchi seas). The majority of the species we love have been getting less and less common, but there's still time to bring them back. Join the Wildlife Trusts on our exciting adventure to a Wilder Future.

The marine mammal community of the Barents Sea and adjacent northern waters represents a vast range of body sizes, from the ringed seal ( m, 60 kg) up to the blue whale (24 m, ,+ kg), and displays concomitant variance in life-history strategies and ecology (Kovacs et al., ).

Mammerickx [and others] Dr. This book describes the marine ecosystem of the Barents Sea, located north of Norway and Russia as part of the Arctic Ocean. Basic knowledge is presented about components of the ecosystem from virus and bacteria via plankton and fish to seabirds through to marine mammals and their interactions with the physical environment.

Ecosystem dynamics are given a prominent role in the book.4/5(2). Plastic waste finds its way into the ocean, and from there to the farthest reaches of the planet – even as far as the Arctic.

This was confirmed in one of the first litter surveys conducted north of the Arctic Circle, carried out by an international research team from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and Belgium’s Laboratory for Polar.

Atlantic (TC, S) waters enter the Barents Sea between Bear Island and northern Norway and dominate the southern region of the sea. During winter the inflow of Atlantic Waters increases, being deep and narrow, while during summer it decreases, becoming wide and shallow (Ingvaldsen et al., a).

The Barents Sea covers an area of approximately million km. 2, has an average depth of ca. m, and a maximum depth of about m at the western end of Bear Island Trough (Figure 1).

Its topography is characterized by troughs and basins, separat ed by shallow bank areas. Christian Lydersen, Ole Anders Nøst, Kit M. Kovacs, Mike A.

In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe the north, the Jan Mayen Ridge separates it from the Greenland Sea.New under-ice net used in large-scale study on the prevalence of polar cod at the ice underside. Using a new net, marine biologists from the Alfred Wegener Institute have, for the first time, been able to catch polar cod directly beneath the Arctic sea ice with a trawl, allowing them to determine their large-scale distribution and origin.
