But they didn’t know just how fast the glacier was melting, and how close it was to complete collapse, until researchers sent an unmanned submarine below the ice shelf. The first measurements ever performed in the dark waters under the 74,000 square mile (192,000 square kilometers) chunk of ice revealed a disquieting piece … Read more
