Differences and Similarities in Freshwater and Marine Shoreline Oil Spill Response

ABSTRACT There are many similarities between marine, lake and riverine environments, as well as differences that involve an adjustment when transferring oil spill knowledge and experience between these environments. Basic elements of shoreline cleanup decision making and response, SCAT, cleanup endpoints, strategies and tactics, apply in all environments. Major differences result due to the different types of water levels and water exposure/processes in tidal, lake and flowing water which effect oil stranding, band width and behaviour, natural removal and cleanup tactics. Tides and waves are the most important water processes in tidal (marine) waters, waves in lakes, and currents and water flow in streams and rivers. Both water level ranges during the time of stranding and the frequency and duration of subsequent water level changes over time are different in marine and freshwater. Oil dilution and spreading potential are greater in marine environments. In general, biological productivity is lower and the...
