The overall result is the development of an extended data base on phytoplankton composition and especially diatom species for 1979-2005. That provides the decision makers with information that can be used to assess the background or reference conditions, the degree of past and present departure from these conditions, and to predict the likely recovery of these systems at reduced nutrient loads.
That facilitates appropriate policy and management measures which can be taken both at the European and national scales. As the determination of background conditions is an integral part of the EU legislation the Water Framework Directive (WFD), this result will have an immediate and relevant impact upon implementation of the WFD.
The data base is still under development, and it will freely be available from the Baltic Sea Research Institute databank to the management authorities at the end of the project.
Together with a free-lance journalist the major outcomes and recommendations of SIBER will be formulated in an easily understandable brochure. The brochure will summarize the major outcomes of SIBER and demonstrate the importance of DSi in the ecosystem functioning of the Baltic Sea and provide managers with a document to enhance their knowledge regarding nutrient cycling.
The following topics are to be handled;
- What is presently known about the role of diatoms in the Baltic Sea ecosystems;
- Reason for concern about the future;
- Which factor regulate diatom production;
- What do we know about the factors behind alterations in phytoplankton species composition in the Baltic;
- Can we control these factors;
- Will sediment archives uncover the last centuries;
- Are the pristine conditions still achievable;
- Are the observed changes in Si cycles an exclusive problem for the Baltic.
A special issue of Journal of Marine Systems will provide the end-user (e.g. environmental scientists, planners, marine ecologists, conservation agencies) with a rapid and broad overview of the project, the major findings and its applied relevance.
The journal is on-line and widely available international through web-based library facilities.
The result is still at the planning stage and will be initiated when all major results are available.
The overall result is the development of an extended data base on nutrient and especially DSi concentrations both for the Baltic Sea (6 basins) and its catchments (106 watersheds) for the entire XXth century.
