Teleconnections and Sea Ice Variability in the Greenland Sea.
The purpose of this study is to examine and test the hypothesis that the multiyear sea ice variability in the East Greenland Current is related to the El Nino/Southern Oscillation phenomenon and/or the North Atlantic Oscillation via atmospheric teleconnections. 'Teleconnection' is defined...
