WATER STRUCTURE IN KONGSFJORDEN, SPITSBERGEN IN 1991-1993
Oceanographic observations in Kongsfjorden (79°N, 12°E), Spitsbergen and in the neighboring seas have been conducted since 1991. This study aims to reveal water exchange processes including exchange; between the North Atlantic Ocean and the Arctic Ocean, and glacier-ocean interaction. Temperature an...
