Satellite availability is becoming wider with the launch scheduled in 2010 of the fourth Cosmo-SkyMed satellite and the two SAOCOM L-band SAR managed by the Argentinean space agency CONAE . While automatic oil spill detection shows good results characterizing other pollutants is less straightforward moreover slick characterization . to define the chemical composition or slick thickness is still an open issue. It is possible that the use of multi frequency and multi polarization data will lead to valuable results. 7.
