Abstract : The purpose of the work was to determine the feasibility of a particular sampler design for the collection of surface oil from a known surface area of water during a finite sampling interval. The determination of average surface oil per unit area is required as a means of establishing an ambient background level of oil pollution, monitoring changes in oil level with time, and relating these changes to pollution sources. The approach used a weir to provide a self-adjusting, wave following means of skimming surface water at a fixed rate determined by a downstream, constant speed, battery driven screw pump. A sorbent material (polyurethane foam), placed in cartridge form between the weir and pump, collected the oil.
