Elevation profile-derived crevasse depths for select Greenland marine-terminating glaciers, 2011-2018
Crevasse depths were extracted from very high-resolution surface elevation observations for 19 fast-flowing marine-terminating glaciers distributed around the Greenland Ice Sheet. Crevasse depths were extracted using a semi-automated moving window approach applied to both NASA (National Aeronautics...

Crevasse depths were extracted from very high-resolution surface elevation observations for 19 fast-flowing marine-terminating glaciers distributed around the Greenland Ice Sheet.
