The journey to collect the data wasn't easy.Scientists dropped Icefin through a 700-meter-deep hole they had drilled through the glacier."We're proud of Icefin,since it represents a new way of looking at glaciers.said Britney Schmidt,lead scientist for Icefin."For really the first time,we can drive miles under the ice to measure and map processes we can't otherwise reach. We've taken the first close-up look at a grounding zone.It's our 'walking on the moon'moment"The grounding zone is the region where the bottom of the glacier meets the sea water beneath it. The team spent the last two months in minus 30'C weather at the glacier for the project.After going down the nearly half-mile hole through the glacier, Icefin swam more than a mile to the grounding zone.As it moved along,Icefin took measurements and recorded what it saw with an inside camera so that scientists could later map the area,as well as understand the temperatures and the changing landscape there. Thwaites Glacier,roughly the size of Florida,which prevents the ice behind it from freely flowing into the ocean,is melting at an increasingly fast rate.Its melting already accounts for about 4%of the global sea rise,Georgia Tech reported.The amount of ice flowing out of Thwaites into the sea has doubled in the past 30 years,greatly changing the landscape,temperatures and the ecosystem of Antarctica. "We know that warmer ocean waters are eroding many of West Antarctica's glaciers,but we're particularly concerned about Thwaites,"Keith Nicholls,an oceanographer with the British Antarctic Survey and the
