I am working with Prof. Dr. Nina Kirchner to model ocean–ice shelf interactions at Petermann Fjord, Northwest Greenland. To that end, I have led a multi-institutional collaborative effort to develop a state-of-the-art, nested, 3D regional numerical ocean model of Northwest Greenland. I have also conducted oceanographic, hydrographic, and glaciological fieldwork targeted towards mapping the marine cryosphere of North Greenland, data from which has been used to constrain our numerical model. Our model, augmented with novel sea ice and ice shelf modules, realistically resolves the seafloor and ice shelf basal topography at an unprecedented 200 m scale. Notably, we have modified the uncharted bathymetry beneath the ice shelf in the BedMachine v3 dataset to rectify implausible abrupt changes in water column thickness and an artificial inner sill which impedes the dense Atlantic Water inflow at depth from reaching the grounding line. Furthermore, we have integrated the IceBridge aerogravity data, which revealed the presence of a 540–610 m deep inner sill at ca. 25 km seaward of the grounding line, into the smoothed bathymetric product used in our simulations to provide an improved representation of the sub-ice shelf bathymetry. Peer-reviewed research articles published thus far using our model are outlined below:
