S9.2.2 - Ecosystem health in the North Sea

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.

Interviews conducted with users and experts to find out what requirements are for this applications. The following quantities were found to be most important

• Temperature, salinity and chlorophyll most important.
• Waves, wind and currents also useful.

• Surface and bottom fields and anomalies, surface-bottom difference.

• Time series.

• Daily for ecosystem health, past data plus five day forecast where available.

1. Whole MRCS domain fine for Ecosystem Health – DESS provides full flexibility for region and zoom

• 6km model resolution adequate for many applications but maybe insufficient for very-near-coast applications.

The system will contain the following information

• Ecosystem information from Met Office Medium Resolution Continental Shelf - European Regional Seas Ecosystem Model (MRCS-ERSEM), plus near real time ecosystem observations (Smartbuoys, Ferrybox, coastal monitoring stations, others)
• Forecast and hindcast information from model and observations, plus model quality assessment by comparison
