Massive hidden waves are rapidly melting Greenland’s glaciers

Researchers in Greenland used a 10-kilometer fiber-optic cable to track how iceberg calving stirs up warm seawater. The resulting surface tsunamis and massive hidden underwater waves intensify melting at the glacier face. This powerful mixing effect accelerates ice loss far more than previously understood. The work highlights how fragile the Greenland ice system has become as temperatures rise.
