Sentences with phrase «beaufort gyre»

You read it right, a melting season that saw mostly cloudy conditions during the sunniest period of the year (June - July - August) has beaten the 2007 melting season which went astonishingly low after weeks of ceaseless sunshine and a massive Beaufort Gyre, continuously compacting the ice pack, well into September.
Our results confirm that runoff is an important influence on the Arctic Ocean and establish that the spatial and temporal manifestations of the runoff pathways are modulated by the Arctic Oscillation, rather than the strength of the wind - driven Beaufort Gyre circulation.»

A large Beaufort Gyre which covers most of the Arctic Ocean during the 1980s, and a transpolar drift stream shifted towards the Eurasian Arctic.
In response to your question I would refer you to my comment above Dave Wendt (14:39:39): where I discuss the Rigor and Wallace paper of 2004 which demonstrated that the decline in sea ice age and thickness began with a shift in state in Beaufort Gyre and the TransPolar Drift in 1989 which resulted in multiyear ice declining from over 80 % of the Arctic to 30 % in about one year and that the persistence of that pattern has been responsible for the continuing decline.
In the Beaufort and Chukchi seas, ice distribution mimicks the Beaufort Gyre circulation pattern with advection of ice from the high Canadian Arctic into the Beaufort Sea and export of ice northward in the Chukchi Sea.

During times when the Beaufort gyre dominates, ice spins in place and accumulates.
On the other hand, during the negative phase of the AO (Arctic Oscillation), water motion in the Arctic Ocean is anticyclonic and the Beaufort gyre is strengthened, so that ice is retained and thickened both in the Canada Basin and along the Siberian coastline, where it may survive summer melting.
These range from few years (Beaufort gyre 4 years, Circumpolar current 8 years, Indian ocean gyre 10 years, N. Atlantic subpolar gyre 20 years etc.) up to above 100 years for some of the Pacific gyres, and finally the great ocean conveyor belt estimated at ~ 1600 years.
Long - term changes in atmospheric circulation have resulted in an increased amount of perennial sea ice being exported through Fram Strait rather than being recirculated (e.g., Beaufort Gyre); this was what set up the 2007 record September minimum.
A shift in the Beaufort Gyre towards less recirculation of ice within the Arctic Basin is partly responsible for the younger pack in the southern and western Beaufort Sea.
In the Arctic, it will be the Beaufort gyre, also caused by the rotation of the earth.
Cumulative ice motions for April — July 2008 derived from drift buoys indicate the overall transport of ice out of the Beaufort Sea around the Beaufort Gyre to the central Arctic was actually much stronger than in 2007, but it appears to be converging (motion is slowing) over the Amundsen and Nansen Basins.
Major features are southwestward advection of older sea ice into the Beaufort Gyre and southwestward advection of different sea ice types toward Fram Strait in the Transpolar Drift.
The June outlook reflects the fact that winds during the last two weeks have reversed the flow of the buoys and sea ice in the Beaufort Gyre and Transpolar Drift Stream, slowing export and sequestering sea ice in the Arctic.
For example, the Beaufort High — an extension of the Siberian High system — is a pressure system that drives the anticyclonic motion of the Beaufort Gyre.
Make a large - scale launch (size determined by previous year's learnings and continued climate modeling) of reflective materials in the Fram Strait or Beaufort Gyre.
The Transpolar Drift and Beaufort Gyre formerly brought new ice into the main pack and exported old ice - mainly on the Atlantic side through Fram Strait.

Curiously, very little of the ice seems to be moving west along the archipelago, towards the Beaufort sea polynya, which I would expect from the action of the Beaufort Gyre.
Yes looking at the IAB maps the Beaufort gyre (a source of multiyear ice) has almost gone, the transpolar drift is apparently running close to the north american side.
«It is believed that in the late 1950s and early 1960s, freshwater and sea ice accumulated in the Beaufort Gyre as a consequence of the prevailing Arctic atmospheric circulation patterns (anti-cyclonic around an Arctic high pressure center.)
In previously ice - rich areas such as the Beaufort Gyre off the Alaskan coast or the region south of Spitsbergen, the sea ice is considerably thinner now than it normally is during the spring.
