Mostly working on projects where I use and develop our in house ocean model, the Bergen Ocean Model (BOM): http://org.uib.no/bom/.
Examples of applications are modeling dispersion of water masses with pollutants, such as micro plastics, in the fjord system around Bergen, dispersion of dissolved CO2 in the North Sea and methods to aid detection of seeps, see publication list.
