"A method for the removal of oil spills on water involves the application of a sinking agent to the surface of the oil spill and the subsequent sinking of the spill. This condensed report contains techniques for the testing of sinking agents to determine their efficiency in the removal of oil, and their ability to retain oil once removed by the action of sinking. The report also provides information concerning the effects of oil layer thickness initially, free fall distance for the sinking agent, temperature and oil type on the efficiency of removal and on the retentivity"--Abstract, page i.

Contains papers presented at ninth Arctic Marine Oilspill Program Technical Seminar held in Edmonton, June 10-12, 1986. Seven sections: properties, behaviour and modelling; biological effects; countermeasures; activity reports/experimental spills/recent spills; detection/tracking/remote sensing; dispersants; and the Freshwater Oil Spill Research Program.
