Almost 3 years after the project started, TOSCA has proved capable of improving oil spill tracking systems. TOSCA has brought updated knowledge on surface currents and noticeable progress in the monitoring of oil slick drift. The added precisions and data collection from this project could now help authorities choose the right strategy for the deployment of drifters to track oil spills. This data could facilitate operations at sea as well as practical and administrative decision-making in the defense of coastlines and public health.
THE TOOLS AND APPROACHES DEVELOPED IN THE FRAMEWORK OF TOSCA AND HOW THEY CAN BE USED BY ACTORS TO ENHANCE THE MONITORING AND FORECASTING OF A DRIFTING OBJECT.
RECOMMENDATIONS TO IMPROVE TECHNIQUES IN THE FIELD OF POLLUTION RESPONSE USING NEW TOSCA TOOLS.
Modeling and forecasting of transport by ocean currents are very sensitive and contingent upon unknown initial conditions, and even small errors in the current results in significant errors in the forecast of a drifting object. For this reason the TOSCA project has framed an innovative approach using HF radars and drifter measurements to provide crucial and complementary information to predict oil spill dispersion and trajectory more accurately.
To provide real-time observations and forecasts, an observational network, based on state of the art technology (HF radars, drifters, ocean modeling systems) was installed and assessed in five sites of the Mediterranean sea, on the coastal areas near the outlets of major existing or planned oil pipelines and on high traffic areas.
To test the monitoring and forecasting capabilities of the system, intensive periods of experimentation have taken place in the five test sites from December 2011 until October 2012
