The system is based on process models applied in a set of nested grids. Hydrodynamics in the study area are calculated with the COAWST modelling system which uses daily boundary conditions and meteorological forcing obtained from the European network MYOCEAN (http://www.myocean.eu/) and from the Spanish met office, AEMET, respectively. Daily COAWST's outputs and meteorological forecast are ready to be used by the oil spill transport and fate model, TESEO. A web service that manages the operational system and allows the user to run hypothetical as well as real oil spill trajectories has been implemented. Data from two hydrodynamics field campaigns and from experimental tests carried out with two types of oils have been used to validate the hydrodynamic and the oil spill models. INTRODUCTION: Up to now, operational oceanography systems (OOS) which provide decision makers with oil spill trajectory forecasting, have demonstrated their usefulness in dealing with recent crisis involving dramatic environmental and socio economic impacts (Castanedo et al., 2006). Accordingly, numerous national and regional OOS have been set up all over the world in order to facilitate and support an adequate response and preparedness (e.g. Olabarrieta et al., 2007). However, occasionally, the available spatial data resolution of these systems is insufficient to be used for coastal applications, and therefore, this information must be transferred to shallow water, in order to increase the spatial resolution (namely downscaling).
CAMCAT: an oil spill forecasting system for the Catalan-Balearic Sea based on the MFS products
Ocean Science Discussions, 2006
The Prestige oil spill crisis (2002-2003), one of the worst oil spills that affected the Atlantic Spanish coastal line, pointed out that some management tools are needed in the form of laws, regulations and technical procedures. In particular, the issues are contingency planning and prevention against marine pollution and prediction for a proper response. In that background, the Catalan local government approved the CAMCAT (2004), a Regional contingency plan against marine pollution, to be framed within the (Spanish) National Contingency Plan. The CAMCAT contemplated the implementation of a Regional Forecasting System for the NorthWestern Mediterranean area, intended to help Catalan Authorities during any pollution emergency. The Laboratory of Maritime Engineering (LIM/UPC) has been responsible for the implementation of this Regional CAMCAT Forecasting System that is based (nested) on existing larger Forecasting Systems/Products, and it integrates several coastal observational data. The present paper is aiming to make an overview of the several scientific and technical activities related to the implementation and validation of the CAMCAT System.

The ESEOO Project, launched after the Prestige crisis, has boosted operational oceanography capacities in Spain, creating new operational oceanographic services and increasing synergies between these new operational tools and already existing systems. In consequence, the present preparedness to face an oil-spill crisis is enhanced, significantly improving the operational response regarding ocean, meteorological and oil-spill monitoring and forecasting. A key aspect of this progress has been the agreement between the scientific community and the Spanish Search and Rescue Institution (SASEMAR), significantly favoured within the ESEOO framework. Important achievements of this collaboration are: (1) the design of protocols that at the crisis time provide operational state-of-theart information, derived from both forecasting and observing systems; (2) the establishment, in case of oil-spill crisis, of a new specialized unit, named USyP, to monitor and forecast the marine oceanographic situation, providing the required met-ocean and oil-spill information for the crisis managers. The oil-spill crisis scenario simulated during the international search and rescue Exercise ''Gijó n-2006", organized by SASEMAR, represented an excellent opportunity to test the capabilities and the effectiveness of this USyP unit, as well as the protocols established to analyze and transfer information. The results presented in this work illustrate the effectiveness of the operational approach, and constitute an encouraging and improved base to face oil-spill crisis.

Oil extraction platforms are potential sources of oil spills. For this reason, an oil spill forecasting system was set up to support the management of emergencies from the oil fields in the Italian seas. The system provides ready-to-use products to the relevant response agencies and optimizes the anti-pollution resources by assessing hazards and risks related to this issue. The forecasting system covers seven working oil platforms in the Sicily Channel and middle/low Adriatic Sea. It is composed of a numerical chain involving nested ocean models from regional to coastal spatial scales and an oil spill model. The system provides two online services, one automatic and a second dedicated to possible real emergencies or exercises on risk preparedness and responding. The automatic service produces daily short-term simulations of hypothetical oil spill dispersion, transport, and weathering processes from each extraction platform. Products, i.e., risk maps, animations, and a properly calle...
Description and Application of the Operational Oil Spill Forecast System Teseo
International Oil Spill Conference Proceedings, 2008
In the framework of the ESEOO Project (Spanish Operational Oceanography System) a complete set of models has been developed to simulate oil spills transport and fate processes. These models have been integrated in a user friendly operational system called TESEO. The main objective of the TESEO system is to integrate the meteorological and oceanographic data as well as the oil properties data required by the oil spill model to provide the evolution of contaminating spills at a regional scale. The system is linked with the operational winds and currents forecast system and, consequently, is able to provide useful information to decision-makers in a crisis situation. The performance of TESEO system has been successfully tested during four operational oil spills exercises organized by the Spanish Maritime Safety and Rescue Agency (SASEMAR) with the collaboration of the ESEOO Group. In these exercises, the TESEO system was used to provide forecast spill trajectories and fate processes to...

Oil spill modeling is considered to be an important part of a decision support system (DeSS) for oil spill combatment and is useful for remedial action in case of accidents, as well as for designing the environmental monitoring system that is frequently set up after major accidents. Many accidents take place in coastal areas, implying that low resolution basin scale ocean models are of limited use for predicting the trajectories of an oil spill. In this study, we target the oil spill in connection with the "Full City" accident on the Norwegian south coast and compare operational simulations from three different oil spill models for the area. The result of the analysis is that all models do a satisfactory job. The "standard" operational model for the area is shown to have severe flaws, but by applying ocean forcing data of higher resolution (1.5 km resolution), the model system shows results that compare well with observations. The study also shows that an ensemble of results from the three different models is useful when predicting/analyzing oil spill in coastal areas.
