PhD project:

Sensitivity of open-ocean convection to ice sheet melting: A regional modeling approach

The effect of meltwater runoff from the Northern Hemisphere ice sheets on the ocean circulation in the North Atlantic Ocean during the last glacial period will be investigated. In this context, it is assumed that the coastal current system in the Arctic and the North Atlantic played a crucial role. The meltwater may have been largely entrained in these coastal currents along the continental shelves and may not have reached the convection sites in the subarctic North Atlantic Ocean.

To this end, a regional sea ice-ocean model is being set up with different horizontal resolutions and forced by global climate model output and specially designed meltwater runoff scenarios. The model domain includes the Arctic Ocean, the Bering Strait and the Atlantic Ocean down to about 10°N. The numerical ocean model is based on the Massachusetts Institute of Technology general circulation model (MITgcm) with an embedded sea-ice component.

This PhD project is part of the International Research Training Group ArcTrain.
