Researcher position at the Nansen Environmental and Remote Sensing Center in Bergen, Norway. A 4-years scientist position is open at the Nansen Center for assimilation of chemical and biological data from satellite and in-situ measurements into coupled physicalbiogeochemistry ocean models. The goal is to improve marine ecosystem models to provide more reliable information to end users by means of data assimilation. Due to the challenges of estimating the parameters of strongly non-linear biogeochemical models, methodological developments in data assimilation need to be pursued. NERSC has implemented for that purpose a variant of the Ensemble Kalman Filter with a Gaussian anamorphosis both into the TOPAZ-NORWECOM model for primary production and into the global ocean Carbon cycle module of the Norwegian Earth System Model (NorESM, in collaboration with the Bjerknes Center for Climate Research). These two activities benefit from strong support, respectively from the European Copernicus marine services and the Research Council of Norway. The candidates should hold a PhD, have a strong background in applied mathematics, genuine interest in marine ecosystems dynamics, and experience in numerical modeling or data assimilation. Experience in parallel programming with complex codes would be beneficial. Starting salary on grade 57 (code 1109/pay framework 24.1) in the Norwegian Civil Service pay grade table; currently NOK 482,800 gross p.a. In the case of highly qualified applicants, a higher salary will be considered following ordinary meriting regulations (wage range 57-65). For an equal level of qualifications, female applicants will be given priority. The start is expected in October 2014 or sooner. NERSC is an independent non-profit research foundation affiliated with the University of Bergen, Norway. NERSC has leading expertise in satellite remote sensing, climate change research, modeling and data assimilation, in particular with the Ensemble Kalman Filter. NERSC has developed the TOPAZ modeling and data assimilation system for the North Atlantic and Arctic Oceans during the last 15 years. TOPAZ is presently the Arctic component of the integrated European marine system for ocean forecasting named MyOcean and is exploited operationally at MET Norway.
