The warm North Atlantic Current (NAC) can be seen as two major shallow and surface-intensified currents in the Iceland Basin, plus a jet in the western Rockall Trough, and the cooler Irminger Current (IC) on the west side of the Reykjanes Ridge.
In addition to this signature of deep convection, the survey also shows the familiar features of the warm and saline Irminger Current on the eastern and western boundaries of the basin, as well as the cold, dense, and oxygen-rich DSOW carried along the East Greenland slope by the DWBC.
In the North Atlantic, the Gulf Stream diverges: The Norwegian Atlantic Current bends east to warm the United Kingdom and Scandinavia, and the smaller North Icelandic
Irminger Current veers around the west of Iceland.
Warm, Atlantic-origin Irminger Current water (mixed with colder local water) often extended from Cape Farewell up the west coast to Fylla Bank or beyond.
2001) observe that after 1970, positive NAO conditions moved the Atlantic Current eastward so that its offshoot, the Irminger Current, had less effect on West Greenland.
One loops back, skirts the southern shore of Iceland and then sweeps southward along the southeast coast of Greenland as the Irminger Current.
At the latitude of Sermilik Fjord, she found the waters of the Irminger Current were very warm--up to 6[degrees]C (nearly 43[degrees]F).
as we infer from the driftwood and bowhead whale records, the Arctic Ocean outflow through Fram Strait should have slackened at the same time, allowing warming of currents downdrift and a relatively greater contribution of
Irminger Current water to the West Greenland Current.
Bower and Valdes knew (from prior satellite measurements of sea surface heights, which indicate currents) that eddies pinch off every two months or so from the
Irminger Current, a warm current that hugs the west side of Greenland and encircles the northern part of the Labrador Sea.
