Surface water conditions in Greenland’s fjords and in the northern Atlantic Ocean are dictated by what’s going on deep below the surface next to the massive Greenland Ice Sheet, UO-led research has found.Breakaway icebergs, according to research findings appearing online Dec. 4 ahead of publication in the journal Nature Geoscience, are the biggest source of freshwater entering the ocean in key areas around Greenland. And the timing and location of meltwater are important factors that should be included in ocean modeling, report the paper’s six co-authors.
