Palaeoclimatic and palaeoceanographic studies from the southern Baffin Bay suggest that, in the past, the development of the Greenland Ice Sheet (GIS) and the oceanic circulation in this area have been tightly coupled. For the northeast Baffin Bay, in which 27% of the western GIS drain, this connection has not yet been established due to the lack of data and samples. In order to model and predict the future responses of the GIS to changing climatic conditions, and hence, changing oceanographic conditions, it is important to better understand the nature of these ocean-cryosphere couplings and related GIS dynamics in the northeast Baffin Bay. For this reason, we systematically mapped the shelf and slope of the Melville Bay (northeast Baffin Bay) for glacigenic seabed features associated to past GIS advances and retreats. To investigate the timing of the GIS advance and retreat events, sedimentary records were recovered from the glacigenic features for proxy-studies. Furthermore, samples for palaeoceanographic ... : MARIA S. MERIAN-Berichte ...
