This colloquium is co-sponsored by the Department of Earth and Planetary Sciences and the WashU Climate Change Program.
The Greenland Ice Sheet has now lost ice mass every year since 1998. While broadscale mass loss is well documented, limits in early remote sensing technology restricted the detail with which we could examine local changes on an ice-sheet-wide scale. Areas of slow motion, glacier shear margins, and complex coastal terrain proved especially challenging. Using newly processed satellite-derived ice sheet surface velocities, glacier terminus advance/retreat records, and surface elevation-change data spanning ~1985-2015, we are now able to see ice sheet changes in unprecedented detail.
