When the NAO first enters a negative phase the sub-Polar gyre contracts towards the west, allowing more warm water to enter the Irminger Sea.

We can observe the gyre in the Beaufort Sea, offshore of the Canadian and Alaskan coasts as well as the ice flux leaving the Arctic Ocean through the Fram Straight, between Greenland and the Svalbard archipelago.
Some of the warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade winds.
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.
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.
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.
As for Antarctic sea ice, that's very interesting and very likely related to the wind trends and their effect on the polar gyres.
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.
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.
Decadal variations in the North Pacific Gyre Oscillation are characterized by a pattern of sea surface temperature anomalies that resemble the central Pacific El Niño, a dominant mode of interannual variability with far - reaching effects on global climate patterns5, 6, 7.
But it's not limited to the gyres; studies estimate there are 15 — 51 trillion pieces of plastic in the world's oceans — from the equator to the poles, from Arctic ice sheets to the sea floor.
Five major sea current gyres are correlated with the dominant wind flows.
The flow of freshwater from the northern continents represents an export to the world ocean that goes almost entirely into the Atlantic, about 5.1 Sv passing as relatively low salinity water through the passages between Greenland and Ellesmere Island into the Labrador Sea, a flow of low salinity water that can subsequently be traced around the subpolar gyre.
The outgoing flow through Fram Strait carries with it large volumes of fresh water as fragmented pack ice, a flow that is strongly episodic at decadal scale and is associated with the series of so called Great Salinity Anomalies observed within the circulation of the subarctic gyre and in the Nordic seas that were discussed in the previous chapter.
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.
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.
This transport produces a broad mounding of water as high as 1 m (3 ft) above mean sea level near the center of the gyre (Figure 6.5).
Eventually, the outward - directed pressure gradient force balances the apparent force due to the Coriolis effect and the water parcels flow around the gyre and parallel to contours of elevation of sea level.
