|2010-09-16: Nest system: Updated module
"Atmospheric data" provides access to the recently released EMEP
deposition modelled data (Report 2010).
"Please note, that the calculations were done with different model versions for different years. ... In 2010 the emissions for the period of 2000-2007 were revised by CEIP based on the latest data submissions to UNECE CLRTAP as of May 2010. For these years air concentrations and depositions have been recalculated with the new emission data. The updated model results are available here along with the original results as reported for the given years" - http://webdab.emep.int/Unified_Model_Results/AN/
|2010-09-13: Access to the SHARK database from the DAS is closed because the SHARK's web interface can not handle enormous amount of demands without problems|
|2010-08-31: DAS: New version (4.5-02) is available. Added access to the SHARK database (SMHI, Sweden) and to the Sumppu marine database, Algabase and Pivet coastal database (SYKE-FMI, Finland)|
|2010-05-21: Nest system: Module "Atmospheric data" (former "EMEP data") now also provides access to the NERI modelling results from the DEHM model ( http://www.dmu.dk/Luft/Luftforurenings-modeller/DEHM/). This dataset comprises data of monthly nitrogen deposition for 1989 - 2006. Thanks to Kaj Mantzius Hansen (kmh at dmu.dk)|

|2009-05-15: Nest system: Updated atm. deposition source - receptor gridded data, compiled by EMEP for the HELCOM Baltic Sea Action Plan. There data are in mass consistent form now, which means that the sum of all contributions from the countries and ship traffic on the Baltic Sea is equal to the deposition from the model run with all sources included.|

|2009-04-08: Beta version of the DAS is available. Added support for the native look and feel. To support users without admin rights the default installation writes everything in the user's space only. Neither the installer nor DAS needs admin rights.|
|2008-12-14: New set of atmospheric deposition data compiled by EMEP for the HELCOM Baltic Sea Action Plan is included in the Nest system. Updated "EMEP data" module now allows to analyse gridded source-receptor relationship data, which describe the contribution from different countries to pollution over the whole EMEP grid. A tool to calculate country-to-area source-receptor matrices is also included.|
|2008-09-29: Updated EMEP module of the Nest system provides an access to the emission data at the EMEP Centre on Emission Inventories and Projections (CEIP) hosted by the Austrian Environment Agency (http://www.emep-emissions.at/). New compilation of the EMEP modelled depositions is also available ( http://webdab.emep.int/Unified_Model_Results/AN/).|

|2008-05-21: The Baltic Sea a century ago - a reconstruction from model simulations, verified by observations. By Oleg P. Savchuk, Fredrik Wulff, Sven Hille, Christoph Humborg and Falk Pollehne|
Our research group is working with questions concerning the turnover of nutrients in marine systems, focusing primarily on the Baltic Sea. This also includes the loading of nutrients from land and air and its relation to human activities. Methods we use are budget calculations, mechanistic models, empirical models and empirical correlation analysis. An important tool in our work are the databases that we have developed, together with other research groups in the Baltic Sea region. Our aim is to understand the biogeochemical cycles of organic matter and nutrients in the Baltic Sea and how they are altered in relation to eutrophication. This knowledge is essential to predict the effect of future loading scenarios, to efficiently manage the Baltic Sea and to decide where in the drainage basin emphasis should be put in terms of land use and carrying capacity.
The decision support system - Baltic Nest - has been developed mainly to provide basis for decision-making at international negotiations. Baltic Nest provides data and information from the entire Baltic drainage basin and the entire Baltic Sea, and links measures on land with effects to the sea. The Nest system was developed within the research programme Marine Research on Eutrophication, MARE*. MARE ended in 2006 and Baltic Nest continues to be maintained and developed within the Baltic Nest Institute, now part of the Stockholm University Baltic Sea Centre.
Baltic Nest Institute (BNI) is an international research alliance between the Stockholm University Baltic Sea Centre, the Swedish Agency for Marine and Water Management, the University of Aarhus and the Finnish Environment Institute (SYKE).
Development and maintenance of the decision support system Baltic Nest is funded by the Swedish Agency for Marine and Water Management.
