  1. MUMM’s Operational Tools and Services for Belgian Coastal Waters Ozer, J. The status of European coastal observing and forecasting Systems. Majorca, 22nd to 24th October 2007

  2. Structure • MUMM • The forecasting system (OPTOS). • Examples of uses of model forecast • Examples of management issues the system (can) help to address. • Forecast accuracy? • Future plans

  3. MUMMhttp://www.mumm.ac.be • Management Unit of North Sea Mathematical Models • Department of the Belgian Royal Institute of Natural Sciences • Modeling: understanding the functioning of the North Sea ecosystem; develop forecasting capabilities • Monitoring: collect marine information (http://www.mumm.ac.be/datacentre) • Management: representing Belgium in a number of intergovernmental conventions – Provide scientific advices on environmental issues.

  4. OPTOS : hydro • COHERENS: “A coupled Hydrodynamical-Ecological Model for Regional and Shelf Sea” (Luyten et al., 1999). • Various implementations • Forcings - Tides - Atmospheric forecast (UK Met. Office)

  5. Optos implementation

  6. Optos : Wave • Core: Hypas 2nd generation model • 3 implementations: North Sea, Southern Bight, BCZ • Forcings: wind + sea surface elevation (BCZ)

  7. Optos Wave

  8. Optos Wave

  9. OPTOS • Run twice a days • Time window: 5 days • UK Met. forecasts • Web access: http://www.mumm.ac.be/EN/Models/Operational/forecasts.php • ftp boxes: sea surface elevation (NOOS, SEPRISE), transports through North Sea cross sections (NOOS), Waves (SEPRISE)

  10. http://www.mumm.ac.be/EN/Models/Operational/forecasts.php

  11. SEPRISE http://www.eurogoos.org/sepdemo/

  12. NOOS: http//www.noos.cc

  13. Optos services • Model results available through ftp boxes. • In case of needs we can forecast the drift of a floating object. • In case of needs, the zooming procedure allows an application of COHERENS in some specific areas. • In case of needs, we can compute the transport of sediments in a specific area.

  14. OPTOS: Float • Drift due to surface currents and wind • Surface current from Optos_NOS and Optos_BCZ • Surface wind form Met. Office • Downwind and crosswind leeway • Time window: 10 days

  15. Optos: float

  16. Sediment transport

  17. Re-analysis

  18. Observations: • RT: Meetnet Vlaamse Banken http://www.vliz.be/vmdcdata/midas/mvb.php?listpar • NRT: SST, SPM, Ocean colour (remote sensing) http://www.mumm.ac.be/OceanColour • NRT: SST, SSS (Beligca) http://www.mumm.ac.be/EN/Monitoring/Belgica/odas.php • Delay mode: e.g. ADCP moorings

  19. Quality control

  20. Quality control

  21. Quality control

  22. Future plans • Improved OBC: coupling with models covering a wider area (ECOOP, MyOcean?) • Ecosystem models in pre-operational mode (ECOOP) • New COHERENS version: ODON • massive parallellisation on multi-processor machines using non-shared memory • Data assimilation: EnKF
