PhD Topic/Title: Aquatic ecosystem response to changing ice margin dynamics of the Greenland ice sheet


Temperatures have been increasing rapidly in western Greenland since ~2000 AD, causing dramatic changes in the Greenland ice sheet (GrIS). It is projected that the subsequent increase in meltwater fluxes enhances the nutrient transport to the surrounding terrestrial and aquatic systems (lakes), altering their composition. In addition, direct warming will also affect the aquatic ecosystems by enhancing stratification and shortening the ice cover period, the consequences of which are still largely unknown. Keechy's PhD-research aims to gain more insight into these latter effects by focussing on the spatial and temporal variability of the aquatic ecosystem in lakes that have remained relatively uninfluenced by the enhanced nutrient transport.
