In November 1991 and in October and November 1992, We made experiments to detect artificial slicked areas by the C-band Synthetic Aperture Radar on the European Remote Sensing Satellite-1. Artificial slick areas were produced by spilling oleyl alcohol from a small ship in the Pacific ocean about 100 km off the coast of Japan. Sea truth data were collected by the research vessel and the small ship used to spill oleyl alcohol. The ERS-1 SAR images were processed by NASDA. The artificial polluted areas were clearly detected by ERS-1 SAR under some different conditions of wind speeds less than 11 m/s. The damping of the scattered power was nearly 4-5 dB for the wind speed less than 11 m/s. However, we could not detect artificial slick by ERS-1 SAR when wind speed was about 14 m/s.
