"MEDITERRANEAN MARITIME POLLUTION: THE ROLE OF REMOTE SENSING TO MONITOR AND MITIGATE" Prof. Goffredo La Loggia Head of the Department of Hydraulic Engineering and Environmental Applications University of Palermo - [email protected] MEDILAB - Remote sensing and Geographical Information System Lab Authors: Goffredo La Loggia, Fulvio Capodici, Giuseppe Ciraolo, Antonino Maltese Palermo June 14, 2010 University of Palermo The need of monitoring and mitigate maritime pollution Human activities contaminate both coastal zone and open sea: - pollutants; - ecosystems; - recovery time. Pollution monitoring and mitigation by integrating: - remote sensing, - hydrodynamic; - bio-optical modelling. Coastal water pollution is strictly related to land activities: -≈ 60% of world’s population lives within 60 km from the coastline impacting water quality. - Pesticides and fertilizers over-application: - coastal zone algae growth; - natural food chain alteration; -coastal waters oxygen deprivation. Offshore pollution is related to maritime oil transport: - a quarter of the global maritime traffic; - causing ≈7% of the world oil accidents during the last 25 years; - biological impacts firstly on open sea than on coastal zone habitats.
