Jens Weiser

Research project

Within ArcTrain, I will be working on project HB-08/2: North-Eastern Baffin Bay response to (early) Holocene warming, supervised by Prof. Dr. Dierk Hebbeln (working group Marine Sedimentology).
I will focus on the interaction of warm-water advection from the North Atlantic and the meltwater runoff from the Greenland ice sheet, using a combination of sedimentological, micropalaeontological and geochemical methods. One of the key quistions is if (and if so to what extent) deglacial meltwater supply may have caused a delayed north-eastern Baffin Bay oceanic response to the Holocene insolation maximum.
