PhD Project

'Impact of meltwater events on weathering and detrital fluxes along the coast of western Greenland, Baffin Bay'

Greenland ice sheet dynamics have a strong effect on meltwater input to Baffin Bay, potentially impacting the oceanic circulation and the ecosystem. This project will investigate the spatial and temporal variation of Greenland meltwater discharge into Baffin Bay and its influence on seawater signatures and circulation during the Holocene. This will be done by studying continental detritus, authigenic minerals and biogenic shell material from marine sediment cores along the northwestern coast of Greenland. The area of focus will be the northern and southern Melville Bay (Northeast Baffin Bay). The methodological focus of this study is based on the analysis of the radiogenic isotopes strontium (Sr), neodymium (Nd) and lead (Pb). The consequential isotope ratios will be used as proxies for source regions of continental detritus and hence transport directions, sea-water sources and advection, and potentially changing freshwater input and weathering through time.

This PhD project is part of the international research training group ArcTrain.
