Outlet glacier flow response to surface melt: based on analysis of a high-resolution satellite data set Open
The dynamics of the Greenland Ice Sheet are affected by surface meltwater reaching the base of the ice, altering ice contact with the bedrock. Lack of understanding of this evolution hampers the ability to predict the effects of increasing…

Widespread increase in dynamic imbalance in the Getz region of Antarctica from 1994 to 2018 Open
The Getz region of West Antarctica is losing ice at an increasing rate; however, the forcing mechanisms remain unclear. Here we use satellite observations and an ice sheet model to measure the change in ice speed and mass balance of the dr…
