Modelling Greenland’s subglacial hydrology using CUAS-MPI Open
Subglacial hydrology plays a key role in many glaciological processes. The amount of water at the glacier base and the properties of the hydraulic system modulate the basal sliding and, thus, ice discharge. The subglacial discharge of fres…

The Greenland Ice-Marginal Lake Inventory Series from 2016 to 2023 Open
The Greenland Ice Sheet and its surrounding peripheral glaciers and ice caps are projected to be the largest cryospheric contributor to sea level rise in the next century. While glacial meltwater is typically assumed to flow directly into …

A new model for supraglacial hydrology evolution and drainage for the Greenland Ice Sheet (SHED v1.0) Open
The Greenland Ice Sheet (GrIS) is losing mass as the climate warms through both increased meltwater runoff and ice discharge at marine-terminating sectors. At the ice sheet surface, meltwater runoff forms a dynamic supraglacial hydrologica…

Indoor radon survey in Greenland and dose assessment Open
Indoor radon and its decay products are the primary sources of the population's exposure to background ionizing radiation. Radon decay products are one of the leading causes of lung cancer, with a higher lung cancer risk for smokers due to…

Heterogeneous timing of freshwater input into Kobbefjord, a <span>low‐arctic</span> fjord in Greenland Open
The majority of freshwater input from Greenland to the global ocean stems from the Greenland Ice Sheet. Currently, almost a quarter of the freshwater flowing from Greenland is derived from catchments that are disconnected from the Greenlan…

Freshwater input into a low-Arctic Fjord in West Greenland: Timing, drivers and model evaluation Open
<p>The majority of the freshwater input from Greenland stems from the Greenland Ice Sheet. Despite its importance in terms of freshwater totals, there is a much higher number of individual catchments disconnected from the ice sheet c…

Reconstructing Greenland Ice Sheet meltwater discharge through the Watson River (1949–2017) Open
Ice-sheet melting is the primary water source for the proglacial Watson River in southern west Greenland. Discharge from the large, approximately 12,000 km2 ice-sheet catchment draining through the Watson River has been monitored since 200…

Maker Buoy Variants for Water Level Monitoring and Tracking Drifting Objects in Remote Areas of Greenland Open
Meltwater runoff from the Greenland Ice Sheet changes water levels in glacial lakes and can lead to glacial lake outburst flooding (GLOF) events that threaten lives and property. Icebergs produced at Greenland’s marine terminating glaciers…
