CALYPSO: LA RETE RADAR HF PER IL MONITORAGGIO DELLE CORRENTI MARINE SUPERFICIALI NEL CANALE TRA LA SICILIA E MALTA (MAR MEDITERRANEO)

Risultato della ricerca: Conference contribution

Abstract

The Malta-Sicily Channel is located within one of the busiest commercial routes in the Mediterranean Sea. Due to the presence of oil tankers and oil rigs, this stretch of sea is prone to oil spill events (both deliberate or accidental) with potentially significant impacts on the local ecosystems and economic activities, such as fishing and tourism activities.Prevention and mitigation measures are needed to reduce risks and impacts. Within this framework the high-frequency (HF) radar technology is able to monitor in near-real time surface currents and waves, thus representing an extraordinary tool to reduce the impact of marine pollution events. Assimilation of near real-time surface current data into numerical models greatly improves the short-term forecast of sea state conditions and, consequently,the forecast of oil spill movements and fate. This paper describes the characteristics and potential of the CALYPSO HF radar observing system. The network, in operation since August 2012, currently includes 4 SeaSonde (CODAR) HF radars working at 13.5 MHz. The system is able to provide 2D surface current maps of the Malta-Sicily Channel with high resolution over a 3x3 km grid, every hour. Surface currents derived by the CALYPSO system were validated using independent measurements (acoustic current meter and drifters), and their accuracy extensively proven. The long term datasets show unprecedented descriptions of surface currents patterns within the studied area.
