Roundup: Martian Glaciers, Icebergs, and Ice-Diving Drones

New Study on Water Ice Cliffs Found on Mars

From Science: “Some locations on Mars are known to have water ice just below the surface, but how much has remained unclear… The ice sheets extend from just below the surface to a depth of 100 meters or more and appear to contain distinct layers, which could preserve a record of Mars’ past climate. They might even be a useful source of water for future human exploration of the red planet.”

Over 1,000 Icebergs in Shipping Lanes in 2017

From The Maritime Executive: “The U.S. Coast Guard’s International Ice Patrol said Thursday that 2017 was the fourth ‘extreme’ season in a row for icebergs in the North Atlantic, with 1,008 bergs tallied in the shipping lanes… The count was high due to powerful storms and to the retreat of Greenland’s glaciers, which both contributed to more calving events.”

Ice-diving Drones on Risky Mission at Antarctic Glacier

From Scientific American: “This month a fleet of seven underwater robots developed by the University of Washington (U.W.) in Seattle is heading into this world on a risky yearlong mission. Their goal: help forecast sea level rises by observing the melting process in this hidden topsy-turvy world, where layers of warm and cool water mix at the shelf.”
