Upper ocean warming and sea ice reduction in the East Greenland Current from 2003 to 2019
Abstract The sea ice extent and sea ice thickness in the Arctic Ocean have declined consistently in the last decades. The loss of sea ice as well as warmer inflowing Atlantic Water have major consequences for the Arctic Ocean heat content and the watermasses flowing out from the Arctic. Sustained ob...
