“Hold the Door”: tv Geoscientists Discover Mechanisms Controlling Greenland Ice Sheet Collapse

Greenland’s more than 860,000 square miles are largely covered with ice and glaciers, and its melting fuels as much as one-third of the sea level rise in Florida. That’s why a team of tv geoscientists’ new discovery of one of the mechanisms that allows Greenland’s glaciers to collapse into the sea has special significance for the Sunshine State.

In , a group of scientists led by , uncovered a process that can control the “calving” of glaciers – when large chunks of glacier ice collapse into the sea, forming icebergs like the one that sank the Titanic. The discovery by the team that included tv PhD student Surui Xie; David Holland, PhD, and Irena Vaňková, PhD, at New York University (NYU) and NYU-Abu Dhabi Research Institute; and Denis Voytenko, PhD, formerly at NYU and now at Nielson Communications, will help the scientific community better model future Greenland ice loss and sea level rise.
