摘要
Remote sensing technique provides an important way for screening oil seepage distribution areas in the early stage of marine petroleum exploration. This paper focuses on the studying of the evaluation method of natural marine seepage slick credibility by using ERS-1/2 SAR and ENVISAT ASAR data. The research is roughly divided into four main steps. Firstly, potential oil slicks are extracted from all images. Next, all oil slicks detected are further classified into several categories according to seepage slick credibility. The obtained oil slick information was then integrated into GIS database to examine the spatial distribution of oil seepage slick. Finally, the paper discusses the present problem on evaluating method. The result shows the potential capability of natural marine oil seepage detection with remote sensing technique for its advantage of low-cost and regional observation.
