Sea ice around Iceland

Ice in the ocean around Iceland has mostly arrived from afar.

It comes here from the Denmark strait, which connects the Atlantic Ocean and the Arctic Ocean, between Iceland and Greenland. Sometimes the ice comes directly from north to the northeast corner of Iceland, but all the ice comes from the same source: the East-Greenland current which flows from the Arctic Ocean due south along the east coast of Greenland, passing northwest Iceland.
