Sentences with phrase «subpolar sea»

The subpolar sea ice loss is mostly in the Sea of Okhotsk and Bering Sea, while the polar sea ice loss is mostly in the Barents - Kara Seas region (Fig. 2).

We also conduct two additional experiments with loss of sea ice placed only in certain regions Subpolar sea ice loss vs. Polar sea ice loss).

Perhaps somewhat more interestingly, we find a clear opposing response in the stratosphere to polar vs. subpolar sea ice loss.

A section on current conditions shows the last two months are characterized by relatively normal atmospheric conditions over the Arctic Ocean, but warmer than normal conditions over the subpolar seas and land around the Arctic Ocean.

At the same time, the subpolar seas are warmer than average and the land surrounding the Arctic Ocean has been warm and both are projected to continue to be warm in August and September.

Not exact matches

I would like to echo Mr. Edmonds inquiry as to the stability of the Pine Island and Thwaites glaciers which seem to connect directly to the Byrd Subpolar Basin, where the ice sheets are grounded far below sea level.

There has been increasing evidence over the last 50 years that the waters of the Subpolar and Nordic Seas have indeed become fresher.

Model simulations for the North Atlantic Ocean and thermodynamic principles reveal that this feedback should be stronger, at present, in colder midlatitude and subpolar waters because of the lower present - day buffer capacity and elevated DIC levels driven either by northward advected surface water and / or excess local air - sea CO2 uptake.

The sea surface temperature (SST) anomalies that define the AMV are characterized by a basin - scale pattern that has the same sign over the whole North Atlantic, with a maximum loading over the subpolar gyre region.

Not only has the AMOC slowed down (Cunningham et al [2013]-RRB-, but sea surface temperatures in North Atlantic subpolar gyre have begun falling, as have sea surface temperatures in the North Pacific subtropical gyre - best illustrated by the Pacific Decadal Oscillation (PDO) being strongly positive this year.

The particularly rapid sea ice loss from 1997 to 2007 was related to extreme ocean conditions that drove a sustained warming of the surface waters throughout the subpolar Atlantic and Nordic Seas.

Ongoing adjustment of the ocean THC is now contributing to a cooling trend in the subpolar Atlantic and an associ - ated slowdown in the rate of Arctic winter sea ice retreat.

Peak abundances of the small subpolar planktic foraminifer species Turborotalita quinqueloba found in MIS 5e sediments from the southern Lomonosov Ridge close to the Greenland continental margin (Site GreenICE, Fig. 1), a region with a modern perennial sea ice cover, may indicate less sea ice than today45.

Essentially, this means that by adding the polar and subpolar experiments, we do not get the same response as the net sea ice experiment in the stratosphere.

This in turn is influenced by sea level pressure patterns in polar and subpolar regions — as more or less wind and currents are pushed north (Roemmich et al, 2007, Qiu, Bo et al 2006).

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.

Therefore, a transoceanic line in the subpolar North Atlantic, currently being planned by the international community, that measures the net contributions of the overflow waters from the Nordic Seas as well as those from the Labrador Sea, to the AMOC, would directly test the legitimacy of the decades - long supposition that variability in North Atlantic Deep Water production translates into meridional overturning variability (Figure 2.4).

This overshoot is caused predominantly by the reduction of the meltwater in the northern North Atlantic associated with the retreat of the large amount of sea ice, an effect that becomes dominant when the subpolar North Atlantic is covered by sea ice as in the glacial condition.
