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.

Sessions included physical behaviour of oilspills, biological effects, shoreline protection and cleanup, combustion and incineration, containment and recovery, dispersants, countermeasures strategies, detection, tracking and remote sensing, activity updates and experimental spills.

Proceedings of the seminar, covering the behaviour and fate of oil; assessment; activity reports from Washington State, Germany, Alaska, British Columbia and Michigan; remote sensing; countermeasures; in situ burning; bioremediation; biological effects; and shoreline cleanup.

Sessions include: Chemical and physical properties and behaviour. - Biological effects. - Spill countermeasures. - Dispersants. - Detection, tracking and remote sensing. - Shoreline cleanup and protection. - Experimental and recent spills.
