Abstract : A study was conducted to trace the fate of petroleum products discharged in the marine environment and to determine the magnitude of the more important weathering variables on the physical and chemical changes which occur. Six carefully selected oils, four crudes, a heavy and a light fuel oil, were weathered under controlled, laboratory conditions in specially designed simulators and under 'real marine' conditions. The progress of weathering was monitored by measuring such physical changes as average boiling points (evaporation rates) and the increase in specific gravity. The effects of weathering parameters on chemical changes in both the floating oil slick and in the aqueous phase below the slick were also measured. The environmental variables investigated included air and water temperature, water wash rate, effects of salinity, effects of air movement and UV light as well as weathering time (up to four months).
