Study reveals causes for freshwater increase in oceans

They found that increasing river discharge and excess net precipitation on the ocean contributed the most freshwater (about 20,000 cubic kilometers) to the Arctic and high-latitude North Atlantic. Sea ice reduction provided about 15,000 cubic kilometers of freshwater, followed by about 2,000 cubic kilometers from melting glaciers.

The sum of inputs from all of the freshwater sources analyzed matched the amount and rate at which freshwater accumulated in the North Atlantic during much of the period from 1965 through 1995.
