Mare Cognitum - Nordic Seas Ecosystem

Insight into the functioning of the ecosystem will serve as a basis for development of prognoses of ocean climate, biological production and state of the fish stocks. This is vital knowledge for our future goal: an ecosystem approach to management of the resource withing the Nordic Seas.

Mare Cognitum was designed to look at the following issues: Large scale circulation; climate and Arctic front dynamics; climate and deep water formation; climate and water mass exchange in the Nordic Seas; Hydrodynamic numerical modelling; organic carbon fluxes and budgets in the Greenland Sea; Climate variability and biological production; vertical mixing, stratification and primary production; the effect of nutrients, light and turbulence on primary and secondary production;, Life histories and population dynamics of Calanus spp.; Interactions and feeding ecology of pelagic fish populations; Migration and feeding of Norwegian spring spawning herring; Climate variability , zooplankton production and growth of Norwegian spring-spawning herring; Biology of salmon during the oceanic feeding migrations; Genetics and population structure of Calanus and blue whiting; Abundance estimation of zooplankton and fish by broad-band acoustics.
