The distribution at sea of seabirds was studied in the North-East Water (NEW) polynya, Greenland, during transect counts in the summers ofand on board the ice-breaking RVs Polarstern and Polar collected within the polynya ‘box’ (78–82°N; 5–18°W) concern observations of birds counted during half-hour counts.
The Barents Sea Region supports some of the largest concentrations of seabirds in the world. A total of 33 species breed regularly in the region, and about million seabirds harvest approximately million tonnes of biomass annually from the ds spend most of the year at sea, visit land only to breed and find all their food in the marine environment.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The pelagic distributions of seabirds in the Greenland, Norwegian and western Barents Seas are poorly known, especially in winter.
This paper describes quantitative observations made in. The metabolic rate of the most important seabirds that breed in the Barents Sea area is shown. Cold blood flowing from the feet towards the body core. SEATRACK aims to map the non-breeding distribution of seabirds breeding in colonies encircling the Labrador, Greenland, Barents, Norwegian, North and Irish Seas, which includes colonies in Canada, Greenland, Russia, Norway incl.
Svalbard and Jan Mayen, Iceland, the Faroe Islands, Ireland and Great Britain. SEATRACK has been a module to SEAPOP since. 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).
As these waters transit the Barents Sea. Distribution of cod and capelin in the northern Barents Sea, autumnand The white areas indicate ice cover and the thin black lines indicate depth.
Figure: Havforskningsrapporten archipelago separates the Barents Sea and the Kara Sea. 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. Fedak, Temperature data from Norwegian and Russian waters of the northern Barents Sea collected by free-living ringed seals, Journal of Marine Systems, /s, 46,(), ().
The Norwegian Sea (Norwegian: Norskehavet) is a marginal sea in the Arctic Ocean, northwest of Norway between the North Sea and the Greenland Sea, adjoining the Barents Sea to the northeast. 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.
In addition, higher sea-ice concentrations (80–%) were between and times as likely to be selected as lower sea-ice concentrations or open water. Ringed seals use the marginal ice zone of the Barents Sea during summer/autumn. In addition, there is a sea level pressure (SLP) ridge over Greenland that drives strong northerly winds through the Fram Strait, facilitating ice export.
In the summer, the SLP contrast is smaller, producing weaker winds. A final example of seasonal pressure system movement is the low pressure system that exists over the Nordic and Barents Seas.
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.
Guillemots are sensitive to temperature and cannot survive if. 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 rationale behind the Nordic workshop, 'What determines the distribution of seabirds at sea?', held in Skibotn, near Troms, Octoberwas the initiation of a new pelagic seabird research programme at Tromsø Museum.
We felt a need to gather experts within oceanography, fisheries biology and marine ornithology to discuss how to best organize such. Sea ice in the Arctic Basin at 26 August ( mkm2): At 26 Augustsea ice was still present in the peripheral seas: packed into the Canadian Arctic Archipelago, off northeast Greenland and the northern Barents Sea as well as the northern Laptev Sea.
This is lots of ice for summering polar bears: Barents Sea and Svalbard.
