2The 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.

15MAPRES rationale and general description The project has been implemented in the following Countries:Italy, Republic of Malta, United KingdomThe starting date was: January 2007The ending date was: December 2007Duration: 12 months
16MAPRES actorsNational Interuniversity Consortium for Marine Sciences - CoNISMa: with two local research units:- L.R.U. 1 Department of Hydraulic Engineering and Environmental Applications– University of Palermo - D.I.I.A.A. (ITA).- L.R.U. 2 Department for the study of the territory and its resources - University of Genova - DIP.TE.RIS. (ITA).Partnership:Lattanzio e Associati (LEA) – ItalyUniversity of Malta (UOM) - International Ocean Institute –Malta Operational Centre (MT)The University of Edinburgh (UEDIN) - School of GeoSciences, Grant Institute (UK)End users:- Italian Coast Guard;- Genova town district.

18Example of Airborne Based Multi-Sensors ACTIVE SENSORSRadar : The sensor mainly used is SLAR (Side Looking Airborne Radar). Works on the X-band (f=9375 MHz, l=3.2 cm)Laser fluorosensors (for oil tickness), :Based on the fact that Fluorescence is a strong indicatorof the presence of oil.Works on the UV (300 to 355 nm) , VIS regionPASSIVE SENSORSIR/UV system ,Thermal IR camera,VIS camera…RadarIRUVnes
