Management of Marine Ecosystems

Case studies will advance understanding of warming on Arctic biology

The new data gathered in INTAROS will be used in a number of case studies to advance ecological and environmental understanding and allow for the expansion of existing environmental and fisheries reporting and management systems into new geographical areas.

The case studies include the following. 

Existing ecosystem models NORWECOM (NORWegian ECOlogical Model) and ATLANTIS (3D ecosystem box model) will be used to integrate data originating from a range of in-situ and remote sensing platforms and geographically different locations, with a view to validating the operation of the models. The initial focus will be on the Barents Sea.

External impacts of climate and environmental change on local marine resources in the Disko Bay area of Greenland will be evaluated. This will be achieved by applying the FLEXSEM model using data assimilation from a range of Arctic observation systems (e.g. Programme for Monitoring of the Greenland Ice Sheet (PROMICE) can supply ice sheet freshwater output estimates), and coupling it to regional hydrodynamic (HYCOM/COHERENS) and ecological (ERGOM) models

The Greenland economy relies heavily on fisheries and past changes in commercial fish stocks have had dramatic consequences for both local communities and the national economy. Building on the existing marine observation system in the eastern Baffin Bay area, supplemented by other data available through INTAROS, trends in ocean temperature and salinity are being analysed in order to quantify impacts on local fish stocks. Work is being carried out to build on the existing environmental and fisheries reporting and management systems for these areas to demonstrate how data from iAOS may allow for implementing similar procedures in other parts of the Arctic.
