Baltic Sea system study

The project involves 4 different disciplines of natural science and a variety methods to study the ecosystem behaviour at scales from seasons to millenia, from local sites to basins. The result is a joint study of budgets and fluxes of matter and energy through the ecosystem.

Data sets were sampled from ships, stations, satellites and other methods. Physical, chemical, biological and geological variables were measured. These data are representative for the actual state of the system and allow process studies (hydrological and meteorological observations) and retrospective studies (geological and historical observations) to take place. The combination of different disciplines allows for a characterization of the ecosystem state dependent on external (climatological) and internal (biogeochemical) forces. Based on empirical observations, the relevant processes are quantified and merged into analytical formulae. Such parameterizations allows improved models to be developed. Models are applied to synthesise background information, construct missing links and make future estimates. They need input from the field observations for both realistic forcing and validation. In particular, special tools are developed for sedimentation dynamics, coastal ecosystems, wind and wave impact, atmospheric load, ice dynamics, coastal ecosystems, wind and wave impact, atmospheric load, ice dynamics, circulation and mixing, and basin-wide budgets. The work results in numerical tools with improved reliability and predictive capability. This is important for consolidated management of a coastal zone. An improved understanding has been gained of processes and predictive capability. A state of the art document of Baltic Science for politicians, science and technology managers and coastal zone decision makers is being created.
