Background

My main position is at the Norwegian Meteorological Institute, where I am heading the Division for Ocean and Ice at the Research and Development Department. The institute has a national responsibility to provide operational forecasts of ocean currents, sea ice and surface waves, which are used e.g. in support of oil spill mitigation and search-and-rescue operations.
