The dataset contains results from a 54 year (1958-2011) numerical ocean model hindcast archive, produced with the Regional Ocean Modeling System (ROMS; www.myroms.org). ROMS is a three dimensional baroclinic ocean general circulation model which uses topography-following s-coordinates in the vertical. This ensures high vertical resolution in shallow areas such as shelf seas and coastal areas. Here, the model is run on a grid with 32 s-layers in the vertical. In the horizontal, the grid resolution is 4 km and covers the Nordic, Barents and Kara seas, as well as parts of the Arctic Ocean.
