Arctic Ice Melt Alters Atlantic Currents


A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, a new study from NASA shows. Using 12 years of satellite data, scientists have measured how this circular current, called the Beaufort Gyre, has precariously balanced an influx of unprecedented amounts of cold, fresh water—a change that could alter the currents in the Atlantic Ocean and cool the climate of Western Europe.
