Polar outflow from the Arctic Ocean: A high resolution model study
Arctic fresh water plays a large role in both the global ocean circulation and the hydrological cycle. To identify sources and pathways of the Arctic outflow into the North Atlantic, results of a high resolution global model and observations have been examined. It is shown that continental runoff an...
