-This application demonstrate model based assessments of algal bloom activity in the NW European shelf seas (including harmful algal blooms) and prepare demonstration products for web based dissemination. Application of dissolved oxygen "nowcast" information to coastal fish farming will also be developed and demonstrated. The system will provide information for evidence based decision making to help reduce uncertainty in the status assessments of ecosystem health in the North Sea, including assessment of the status of the OSPAR indicators including dissolved oxygen concentration, and will provide demonstration of the larger-scale ecosystem health indicators application to coastal aquaculture.+This work package addresses 'Ecosystem Health in the North Sea', intended for decision makers concerned with monitoring and predicting the health of marine ecosystems - for example whether there is a risk of algal bloom, poor water quality, or danger to marine organisms. The information provided is past, present and forecast ocean information from the UK Met Office Shelf-Seas physical and ecosystem numerical model (which is called MRCS-ERSEM), together with ocean measurements from several fixed and moving platforms. These include:  
 +  * SmartBuoys operated by the Centre for Environment, Fisheries and Aquaculture Science  
 +  * Ferrybox systems operated by the UK National Oceanography Centre, and the Norwegian Institute for Water Research  
 +  * Fixed platforms that contribute observations to EuroGOOS, through the SEPRISE project  
 +Other observations are to be included during the demonstration phase. Standards based data services have been used where possible: Open Geospatial Consortium Web Map Services for maps, Web Feature Service for observations, and THREDDS OpenDAP for gridded data. This addresses another aim of the project: to provide interoperable systems that can be combined for different uses and in different regions.
