It has long been known from the synthetic aperture radar (SAR) data record that marine slicks can be identified as zones of reduced backscatter separately from the surrounding wind-roughened waters. The composition and properties of marine slicks dampens the shortwave field by both suppression of wave growth and increase in wave dissipation, through an increase in surface tension and a reduction in...
We challenge the often-made claim that fully polarimetric synthetic aperture radars (SARs) are beneficial for discriminating between mineral oil films and biogenic slicks. We conjecture that the results obtained from previous analyses of spaceborne polarimetric SAR data, which seem to show differences in the scattering mechanism between radar scattering from mineral oil films and biogenic slicks,...
We report here an analysis of the polarization-dependence of L-band radar backscatter from the main slick of the Deepwater Horizon oil spill, with specific attention to the utility of polarimetric decomposition analysis for discrimination of oil from clean water and identification of variations in the oil characteristics. For this study we used data collected with the UAVSAR instrument from opposing...
