ABSTRACT The application of dispersants to an oil-slick is a key remediation tool and thus understanding its effectiveness vital. Two in situ oil slicks were created the North Sea (off coast Netherlands), one left natural processes whilst dispersant (Slickgone NS) was applied other. GC-MS analysis seawater from surface slick, at 1.5 5 m below revealed only two samples with measurable hydrocarbo...

A study on the potential of space-borne polarimetric synthetic aperture radar (SAR) imagery for an improved detection and classification of oil spills is presented. An image data set consisting of five SIR-C/X-SAR acquisitions over the North Sea, English Channel, and Southern Italy is used. Results show that two land surface roughness indicators (i.e., the circular polarization coherence (CPC) ...

Natural and oil surface slicks are widespread phenomena at the air-water interface represent visible films with distinct physicochemical biological properties compared to non-slick underlying marine water. Both types of have major functions in nourishing dispersing surface-dwelling micro- macroorganisms, contribute particle generation carbon cycling, known accumulate pollutants. Despite these h...

ABSTRACT: GIS can significantly contribute to correct interpretation of the signatures of slicks visible on synthetic aperture radar (SAR) images, providing a basis for analysis. Proposed geoinformation approach to oil spill mapping is presented. It includes integration of the geographical, remote sensing, oil & gas infrastructure data and slick signatures, detected in SAR images, in GIS. Vario...
