Arctic terrestrial hydrology and biogeochemistry

We are studying a chronosequence in southwestern Greenland to determine how deglaciation impacts landscape hydrological and biogeochemical processes. Impacts include changes to land-water interactions, development of soil and microbial communities following ice retreat, carbon and nutrient cycling across the land-aquatic continuum, and changes in metal speciation and mobility. We are studying these impacts across Arctic landscapes, streams, and lakes and comparing results with streams directly draining the Greenland Ice Sheet to observe differences between ice-covered and ice-free landscapes. These determinations will allow us to make inferences about changing hydrology and biogeochemistry across Arctic landscapes experiencing deglaciation and environmental change, as well as make inferences about environmental change over past and future glacial-interglacial cycles.
