Massive hidden waves are rapidly melting Greenland’s glaciers

From ScienceDaily

Iceberg calving happens when large pieces of ice split from the front of a glacier and fall into the ocean. This natural event is a major contributor to the rapid reduction of ice on the Greenland ice sheet. For the first time, an international team led by the University of Zurich (UZH) and the University of Washington (UW) has used fiber-optic technology to track how the impact of falling ice, along with the movement of the released ice, causes glacial meltwater to mix with warmer seawater below the surface.
