We study the consequences of increasing water temperatures on species interactions in Arctic benthic coastal communities. From these investigations we predict future scenarios for a warmer marine Arctic ecosystem and its [...] from the Interreg North-West Europe Programme.

These archives contain what is referred to [...] However, these models do not reflect in detail processes in the ocean, which have a major influence on the climate. In response, the AWI has developed a special ocean model (FESOM), which simulates e.g. ocean currents and sea ice. For their climate simulations, AWI researchers have coupled the two atmospheric models and FESOM, yielding
