According to the report (june 2010) from CNRS, IFREMER, WHOI, METEO FRANCE, CLS, NATIONAL OCEANOGRAPHY CENTRE et MERCATOR
On June 2 2009 at 8h16 a possible pollution spot was detected near 30°30.5’W 2°43.4N by the synthetic aperture radar (SAR) on board the COSMO SkyMed 1 satellite. Figure A7_1 below shows the cusp shaped spot detected, which does not have the characteristic elongated form of an oil spill coming from a ship. it is not impossible that this pollution spot may be the remnant of a kerosene release by the plane AF447
