Close Passage

WHOI mooring technician John Kemp surveys the shoreline of Greenland as R/V Knorr transited through Prince Christian Sound at the extreme southern end of the island. The sound is 60 miles long, but only 1,500 feet wide in spots, and connects the Laborador and Irminger Seas—locations where a team led by WHOI physical oceanographer Bob Pickart recently deployed moorings and took samples as part of the Overturning in the Subpolar North Atlantic Program (OSNAP). Pickart along with Amy Bower and Fiamma Straneo are part of the international program designed to provide a continuous record of the heat, mass and freshwater between basins and across the entire water column of the subpolar North Atlantic.(Photo by Carolina Nobre, Woods Hole Oceanographic Institution)
