The main service delivered by MEDESS-4MS will be an integrated real time operational oil spill forecasting service for the Mediterranean for national response agencies, REMPEC and EMSA.
The multi-model oil spill forecasting system is composed of environmental information from the GMES Marine Service and the national ocean forecasting systems interfaced with oil slick data from existing monitoring platforms from EMSA CSN, as well with AIS data.
It will use the real time information about position of the oil slick, interface it with oil spill models capable to forecast the movement of the pollution providing tailored products to oil spill crisis management users, contributing substantially to maritime risks prevention and maritime safety.

The service will be accessible through a User Interface that will be basically a web portal on which the MEDESS-4MS services will be made available. The system will be accessed by different users’ categories and will thus implement authentication services, profiling, management of customised contents, centralised administration.
Users will have the possibility to choose the MEDESS-4MS oil spill model that best satisfies their local or sub-regional needs, select the necessary forcing data from the output of local, sub-regional and regional ocean and meteo forecasting systems.

MEDESS4MS Service Scenarios
The MEDESS-4MS services will be delivered through 3 service scenarios (SS), in order to assist operational response agencies:
SS1- Real time interactive oil spill predictions by the end-user request. It will be an automatic system that will run after an oil spill alert from satellite data. It will be a scenario used by selected authorised users (i.e. official agencies of Member States).
SS2-Delayed mode simulations by end-user request. In this solution, intended for the use of REMPEC and generic users, the UI provides means to access monitoring component, environmental data and model outputs and receive integrated remote/in-situ data. The User will query the NDR Service to consult historical data, for study or statistical purposes and possibly query the NDR to back trace data with the aim of identifying possible polluting ships.
SS3-Decision support system (DSS) to manage emergency operations. The services will be consisting of a DSS that will be an operational tool proposing to the users a set of possible scenarios, developed according to the foreseeable meteo-marine conditions and to the possible on-site interventions. The DSS will then be used for oil spill crisis management and built upon a set of simulation functionality, launched by the UI to support the work of operational decision makers.
This last SS include also the work dedicated to specifically support REMPEC. MOON partners started to collaborate with REMPEC by providing real-time oil-spill, meteorological and oceanographic forecast and observations; co-operation continued and was formalized in a collaboration agreement between MOON partners and REMPEC signed in 2009 ( In the framework of the MOON-REMPEC partners have established the Emergency Response Office (ERO) (link at ERO in to serve as the coordinating body for the MOON ERO Experts who provide oil spill monitoring and forecasting bulletins, including meteo-oceanographic forecasts, to REMPEC to support REMPEC in the emergencies operations management.
ERO system will be further developed in MEDESS4-MS and the ERO bulletin maker User Interface will be created to allow the system to automatically produce the ERO bulletin based on the input of the ERO experts.
