Abstract
An oil slick sampling apparatus and method wherein a substantially annular hoop-like frame adapted to float on water and surround the slick, has an inner annular surface coacted with a surface active material which functions by spreading to compress the area of the oil slick. According to one embodiment the frame is hollow and has one or more openings to collect the oil slick as it is compressed by the inwardly spreading area of the surface active coating; according to a second embodiment the frame is impervious and the slick is compressed by the surface active material inwardly toward a central area thereof whereat suitable collecting means is located to collect the oil slick for further analysis.
