A fully parallelized ice-ocean model (HIROMB, High Resolution Operational model for the Baltic) is used both for operational services and in research projects. HIROMB is driven by a N Atlantic storm surge model, surface fluxes from an atmospheric model and fresh water inflow from a hydrological model. HIROMB also serves as one main component in an operational ecological model, built on SCOBI, an atmospheric load model and a hydrological load and runoff model. 
 
 

Above, results from the HIROMB model are presented. Salinity and currents at the dynamically active region where the Gulf of Finland meets the Central Baltic Sea. Eddies are often formed where we have the highest density gradient and as an example, two counter-rotating eddies are seen at about 22.5°E.
