WASHINGTON, Sept. 30 (UPI) -- Scientists at NASA are keeping an eye on the plumes of sediment that appear in the ocean as glacial meltwater deposits sand, soil and rocks. The plumes, which are visible via satellite imagery, may be able to help scientists ascertain exactly how much ice mass glaciers are losing to the ocean via meltwater runoff.
NASA's Earth Observatory recently captured a beautiful image of the Greenland Ice Sheet. The image shows the whitish turquoise sediment plumes snaking out from the glacial fjords of Greenland and into the Labrador Sea. "The sediment wonderfully stands out behind the blue marine waters," said UCLA researcher Vena Chu, "and makes it easy to see in remotely sensed satellite imagery."
