Film shows Geophysical Institute research in harsh Greenland landscape

The wind’s low, rumbling howl fills the ears for 89 seconds before a human voice is heard. The ice and snow of Greenland’s expanse passes below, seen through the lens of Brooklyn, New York, filmmaker Iva Radivojevic aboard a NASA surveillance aircraft.

Global study of glacier debris shows impact on melt rate

Credit: David Rounce A large-scale research project at the University of Alaska Fairbanks Geophysical Institute has revealed insight into the relationship between surface debris on glaciers and the rate at which they melt. The work is the first global assessment of Earth s 92,033 debris-covered glaciers and shows that debris, taken as a whole, substantially reduces glacier mass loss. The results will affect sea level rise calculations and allow for improved assessment of hazards faced by nearby communities. This is the first step to enable us to start projecting how these debris-covered glaciers are going to evolve in the future and how they re going to affect glacial runoff and sea level rise, said glaciologist David Rounce, the lead author of a paper published April 28 in
