ESA Video Shows Growth of Crack That Created Giant Antarctic Iceberg

A giant ice sheet that scientists had been monitoring for years has finally broken off from Antarctica, creating a Delaware-sized iceberg in the Southern Ocean. The 6,000 sq km block “calved” away from the Larsen-C ice shelf, and was believed to be among the 10 largest icebergs ever recorded, according to reports. NASA reported the change would not lead to increased sea levels immediately, as the ice shelf was already floating on the ocean, but warned that it would now be easier for glaciers on the Antarctic continent to move towards the sea. “Ice shelves float, so they do not directly contribute to sea level rise,” they wrote. “They are important, however, because they buttress land ice and keep it inland. If a shelf disintegrates, glaciers that feed it can flow more quickly out to sea—a process that directly increases sea level.” This video, published by the European Space Agency and containing modified Copernicus Sentinel data (2017), processed by A. Hogg/CPOM/Priestly Centre, shows the growth of the crack over a number of years. Credit: ESA/Copernicus Sentinel data (2017), processed by A. Hogg/CPOM/Priestly Centre via Storyful
