Abstract: For over a decade, the Geological Survey of Denmark and Greenland has monitored the Greenland ice sheet to get accurate insights into the loss of ice. Such insights are crucial if we are to predict future changes in the ice sheet and their impact on sea-level rise. As the ice sheet loses mass, the flux of freshwater to the fjords increases thereby affecting local ecosystems and marine life, and ultimately local communities. In this talk, I will show how different processes control the freshwater flux for different fjords, and how our results enable us to quantify the dominant freshwater term and the seasonality of the freshwater input from glacier to glacier. Finally, I will share my latest fieldwork experiences and insights from our most recent monitoring programme that aims to constrain the snowfall in the interior of the ice sheet.
