Accelerating ice flow at the onset of the Northeast Greenland Ice Stream
Deep in the interior of the Greenland ice sheet, ice flow is speeding up — but not due to recent changes in climate.

Sep 23, 2022As we warm our planet, oceans expand, ice on land melts, and sea levels rise. On century time scales, we find that the sea level response to warming can be characterized by a single metric: the …
Feb 2, 2020We present an approach to normalize hurricane damage, where damage is framed in terms of an equivalent area of total destruction. This has some advantages over customary normalization schemes, and we …
Dec 1, 2019Catalina lake is a gigantic glacier dammed lake on the Renland peninsula, in the Scoresbysund region in East-Greenland. Every 1-2 decades it breaks through the glacier dam and a very large volume of …
Nov 17, 2024Firn densification is the process by which snow transforms into glacial ice. Snow accumulates and compresses over time, causing the snowflakes to compact and recrystallize. Initially, the snow is …
Nov 17, 2024How can we estimate how much extra hurricane damage we can expect due to sea level rise alone?
Nov 17, 2024Ice sheet models assume a flow law for solid ice. However, damaged/crevassed ice may will effectively be less viscous than undamaged ice. We need a better way to handle this in ice flow models.
Nov 17, 2024Ice streams can display oscillatory and even chaotic behaviour. How does the state of ice streams influence the predictability of the ice sheet response to anthropogenic forcing?
Nov 17, 2024The ice sheets are vast and direct observations of many processes are sparse. How can we apply ML techniques to remote sensing data to fill gaps.
Nov 17, 2024Sea level rise will become a huge challenge for coastal societies around the world. We need good data, we need good models, and we need to understand all changes.
Nov 17, 2024Abstract During the Holocene, the Greenland Ice Sheet (GrIS) experienced substantial thinning, with some regions losing up to 600 meters of ice. Ice sheet reconstructions, paleoclimatic records, and …
Jul 16, 2024We uncover a new failure criterion for ice using a large dataset of greenland crevasses. Abstract Ice fractures when subject to stress that exceeds the material failure strength. Previous studies have …
