Introduction<br />

An important step in oil spill response is assessing the quantity of oil spilled on the<br />

water. This information is used by the response team to prioritize response and, if<br />

necessary, direct cleanup resources.<br />

If the source and cause of the pollution is known, oiling and fueling logs can be used<br />

to determine the volume of product spilled. However, if the incident is a marine<br />

mystery sheen, the characteristics of the sheen is the only indication to determine oil<br />

quantity and the ability to contain and/or recover it. Gray or rainbow color sheen, for<br />

instance, is a very thin layer of oil which cannot be recovered with sorbent materials or<br />

skimmers. Only thicker layers, typically True Color or heavy Metallic layers, are<br />

considered thick enough to be effectively recovered.<br />

This booklet was designed to help you perform efficient assessments of pollution<br />

events and communicate your findings to the <strong>Alaska</strong> Department of Environmental<br />

Conservation (ADEC) Division of Spill Prevention and Response (SPAR).<br />
