Monitoring of Helheim Glacier Dynamics Using the Open-Source High-Resolution Satellite Imagery
In recent years, climate change-driven pressures have been causing accelerated ice loss on the Greenland Ice Sheet, leading to the gradual seal level rise. Monitoring of spatio-temporal changes (STCs) created by ice melt and calving is essential for comprehending present glacial dynamics, as well as...

In recent years, climate change-driven pressures have been causing accelerated ice loss on the Greenland Ice Sheet, leading to the gradual seal level rise. Monitoring of spatio-temporal changes (STCs) created by ice melt and calving is essential for comprehending present glacial dynamics, as well as for the forecasting of future trends. In this study, we investigate the suitability of open-source high-resolution (HR) satellite imagery from various satellite constellations for monitoring and quantifying of multi-year glacial dynamics. Monitoring of glacial dynamics was applied for a multi-year period (2010–2023) over the Helheim Glacier, one of the largest outlet glaciers of the Greenland Ice Sheet. Multi-year STCs at the Helheim Glacier were determined using the open-source satellite imagery provided by Google Earth Engine (2010–2016) and the Planet constellation (2016–2023). To determine multiyear glacier dynamics, the terminus of the Helheim Glacier was extracted from available satellite imagery.
