Coastal Research at the IfK@HZG
Three key questions
a)What is the present synoptic state of the costal sea? (COSYNA)b)What are the long term (decades of years) changes in the coastal zones, and which changes may be expected fur the future? (CoastDat)c)What are the spatially distributed properties of the coastal sea floor? (CoastMap)

COSYNA develops methods for the operational (routine) description (analysis) of the state of the North Sea, or parts thereof in terms of physical state, water quality and ecosystem, in the past (months), presence and future (days).This is achieved by means of “products”, which are accessible for stakeholders
First COSYNA products1.Mapping of currents in the German Bight; radar-data (WERA) assimilated into numerical models. Present status plus 3 day forecast (running)2.Forecast of salinity and temperature of the North Sea (in preparation)3.Forecast of suspended sediment matter (in preparation)

An institution set up to enable communication between science and stakeholders
Typical stakeholders: Coastal defense, agriculture, off-shore activities (energy), tourism, water management, fisheries, urban planning
• that is: making sure that science understands the questions and concerns of a variety of stakeholders
• that is: making sure that the stakeholders understand the scientific assessments and their limits.

An effort to establish which scientifically legitimized knowledge about anthropogenic climate change is available for the Baltic Sea catchment.
Approximately 80 scientist from 10 countries have documented and assessed the published knowledge.
The assessment has been accepted by the inter-governmental HELCOM commission as a basis for its future deliberations.
In 2013 a second assessment report (BACC II) will be published.

Land-Ocean Interactions in the Coastal Zone (LOICZ)
LOICZ is an international research project and network involving more than 1000 scientists and over 50 individual research projects from across the globe who have been investigating changes in the biology, chemistry and physics of the coastal zone since 1993. Since 2003, LOICZ has expanded its areas of research to include social, political and economic sciences in order to address the human dimensions of the coastal zone and since 2006 LOICZ is hosted at the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht.
Mission: LOICZ, working to support sustainability and adaptation to global change in the coastal zone.
Currently LOICZ is focusing on these Hotspots:
Urbanization in coastal zones Arctic River Mouth System, incl. Dltas and Estuaries Islands at risk
LOICZ is a core project of the International Geosphere-Biosphere Programme (IGBP) and the International Human Dimensions Programme on Global Environmental Change (IHDP) which are part of the Earth System Science Partnership (ESSP)

Take home
The research program of the Institute of Coastal Research takes into account questions of stakeholders and of the public, while maintaining a high scientific standard.
This presentation described only parts of the program; the embedding into the overall program of the Helmholtz Association of German Research Centers has not been described. Also other elements of cooperation within the German community of coastal and oceanic researchers has not been addressed.
Three key projects of the Institute of Coastal Research have been briefly sketched: The development of methods/technology for monitoring the coastal seas (COSYNA) with relevance of planning and management, the assessment of ongoing and expected future change in coastal zones (CoastDat) with relevance of risk analysis and adaptation, and finally CoastMap dealing with conditions, vulnerability and exploitation of the coastal sea bottom.Also some work on building community and dialogue with regional stakeholders is part of the program.
