Large 3D hydrodynamical numeric models for the Barents Sea have, through validation with observations, proved to be a useful tool for filling observation gaps in time and space. The hydrodynamical models have also proved useful for scenario testing, and for study of drift patterns of various planktonic organisms. These models are developed and runned at several Norwegian and Russian institutions, at different scales and resolutions.
Sub-models for phytoplankton, zooplankton, fish larvae and even fish are now implemented in some of the hydrodynamical models. However, due to the present assumptions in these sub-models care must be taken in the interpretation of the model results.
