This week from AGU: Undercutting glaciers, ocean research & five new research papers

July 15, 2015


Greenland's fjords are far deeper than previously thought, and glaciers will melt faster, researchers find West Greenland's fjords are vastly deeper than rudimentary models have shown and intruding ocean water can badly undercut glacier faces. A new study in Geophysical Research Letters explores how this process will raise sea levels faster than expected.
