I work at the technical departement at the Geophysical Institute. Work tasks concern field activities, including preparations, cruises and post-cruise work for the oceanography group.

I defended my dissertation on August 11 2017. In my thesis I studied diapycnal mixing processes in the Arctic Ocean, specifically around the Yermak Plateau north of Svalbard. The reduced sea ice cover in the Arctic can allow more wind energy to penetrate into the upper mixed layer. In addition to direct wind mixing, we can expect an increase in near-inertial internal waves, which have the potential to propagate downwards, and lead to an increased vertical heat exchange with the relatively warm Atlantic Water layer.
