New map captures the Greenland Ice Sheet in unprecedented detail
A new high-resolution dataset provides the most detailed and up-to-date map of the Greenland Ice Sheet so far, showing the ice margin in late summer 2022. The dataset can be used to improve ice sheet ...

PROMICE-2022 ice mask: a high-resolution outline of the Greenland Ice Sheet from August 2022
Abstract. The Greenland Ice Sheet (GrIS) is losing mass at an accelerating rate in response to climate change. Its geometry responds to these changes over annual to decadal timescales, therefore makin...

🔬 New research! We studied epilithic biofilms in Greenlandic streams across a large climate gradient to uncover what shapes these microbial communities. Water temp, nutrients & catchment slope were key drivers! 🌍❄️🏔️ Curious? Full story ⬇️ enviromicro-journals.onlinelibrary.wiley.com/doi/10.1111/...

Drivers of Epilithic Biofilms in Greenland Streams: The Role of Nutrients, Temperature and Catchment Slope Across a Climate Gradient
Microbial biofilms are crucial components in Arctic streams, and understanding how climate warming affects them is critical. Across three regions in Greenland, we found large differences in biofilm s...

Our new paper on West Greenland’s local glaciers and ice caps is finally online in the Journal of Glaciology. We have been looking into area, volume and ELA changes from 1985 to 2020 More info here: www.cambridge.org/core/journal... #greenland #glaciers #glaciology

Out today! The results of an awesome multidisciplinary collaboration of dozens of scientists across the globe (including me, in a very minor role)! A rockfall into a glacier into a fjord in Greenland caused a tsunami and seiche that generated a monotonic seismic signal for 9(!) days!

Our study on landslide-initiated tsunamis is out! We find evidence of giant, prehistoric tsunamis coming from Vaigat strait, in the lakes of Saqqaq, W Greenland. Thanks for the enjoyable collaboration to all involved: Kristian, Anne Sofie, Gregor, Mimmi, & Nicolaj!

Evidence of Middle Holocene landslide-generated tsunamis recorded in lake sediments from Saqqaq, West Greenland
Abstract. The Vaigat strait (Sullorsuaq) in West Greenland is well known for its susceptibility to landslides and historical landslide-generated tsunamis. Recent mapping of the seabed in the Vaigat st...
