Statistical description and forecast of the coastal and harbor waters as a tool for oil spill detections Enrique Álvarez Fanjul Puertos del Estado Final EU-MOP project workshop
Required Met-Ocean info during an oil spill accident What sea conditions can I expect in the region in this time of the year? (wind, waves, sea level, currents…) Which is the actual sea-state condition now and in the following days? In which direction the oil is drifting? Which are the sensible coastal areas? How will the oil chemically evolve?
Which are the tools needed to answer? Measuring networks (buoys, tide gauges) Statistical description of the environment Forecast models of ocean and the atmosphere Oil spill models Weathering models
Met-Ocean Info Evaluation, analysis and compilation of information CRISIS MANAGERS How are the tools employed and organized? Meteorological models Ocean models Spill models Data (Real time): Buoys Satellites Radars Climatology
What was the ESEOO project? ESEOO (Establecimiento Español de Un sistema de Oceanografía Operacional) was a three year project funded by the Spanish Science and Education Ministry. Final meeting: January 2007 14 Spanish groups and 7 non-Spanish
ESEOO Participants Nacional centers: Puertos del Estado Sasemar Instituto Nacional de Meteorología Instituto Español de Oceanografía INTA ICM/CSIC e IMEDEA Universities: Cantabria, Málaga, Vigo, Cádiz, Polit. de Barcelona, Las Palmas, Granada, Santiago de Compostela, UNED Centers from other countries: NRL (EE.UU.) UK Met Office (U.K.) Le Cedre (Francia) POL (U.K.) Mercator (Francia) MFSTEP (Italia) IST/Hidromod (Portugal) Coastal autonomic centers: Meteogalicia Azti
Some ESEOO results Development of a regional scale national oil spill and current forecasting system. Set-up of high resolution numerical models and systems able to forecast currents and spill evolution at local scale. Development of an data service able to quickly provide information based on analysed historical measurements. Set-up of a unified access point to real-time oceanographic and meteorological data at Spanish coasts.
Real time data services
Services based on measured data
Statistical information: a example from ESEOO Wave Climate at Galician coast (winter)
ESEOO ocean forecast system OPERATIONAL CURRENT FORECAST AVAILABLE ON THE WEB (www.eseoo.org) Forcings: Tide Wind Atmospheric pressure Heat and fresh water fluxes River outflow
Finisterre 2006 oil spill exercise Galicia coastal waters Drifting buoys were released to check the tools and developments Oil spill and search and rescue operations were simulated Two ships and one helicopter were employed for the release of the buoys
The tools employed at FINISTERRE 2006 ESEOO regional scale current forecasts ESEOO coastal models TESEO oils drift forecast model Real time data broadcast of results and forecasts by Internet
Forecast and actual trajectory of a drifting buoy Finisterre 2006 results
Conclusions: Operationally oceanography tools are critical for the treatment of an oil spill crisis (measurements, forecast, statistical knowledge) Specialized personnel is required for the evaluation, analysis and compilation of information ESEOO project has contributed to develop and structure OO at Spanish national level. New basic products are now available and integrated with users The ESEOO group has created “critical mass” for research and a common access point for OO at Spain
