Knorr returns to Greenland

This photo was taken on Oct. 29, on the Knorr’s return to the port of Nuuk, Greenland. The mission is part of a seven-year international effort to monitor and measure the changes in fluxes connecting the North Atlantic and Arctic oceans and how those changes might contribute to climate variability. The operation covers the areas of the Davis Strait, the Northern Labrador Sea and the Southern Baffin Bay at depths of 300 to 400 meters.(Photo by Steve Walsh, Woods Hole Oceanographic Institution)
