The project addresses several of the main themes of Bonus and has a high relevance for the Call. Baltic‐C will for the first time construct the organic and inorganic carbon budgets of the Baltic Sea addressing C fluxes from land, the exchange fluxes with the atmosphere and the sediments as well as addressing internal C fluxes in the water bodies of the major basins. Only such holistic description of all C fluxes will allow scenario analyses on possible impacts of eutrophication, climate change and acidification.

Baltic‐C objectives are to develop and apply a new integrated ecosystem model framework based on the cycling of organic carbon (Corg) and carbon dioxide (CO2) in the Baltic Sea water, drainage basin, atmosphere, and sediments.

The outcome of the project will be a model framework in support of water management of the Baltic Sea and its ecosystem addressing the consequences of climate change, eutrophication, increasing atmospheric CO2 and acid precipitation and demonstration applications of the framework of direct value for management.

The Baltic‐C program will be organized into three major themes: Programme managements, observations and modelling. Total costs for different threats will be calculated and dissemination of the results will be in close cooperation with BONUS, BALTEX, Baltic Nest, HELCOM and the Swedish Water District Authority.
