| A very thin layer of oil (less than 0.0003 mm in thickness) floating on the water surface. Sheen is the commonly-observed form of oil during the later stages of a spill. Depending on thickness, sheens range in colour from dull brown for the thickest sheens to rainbow, grays, silver, and near-transparancy in the case of the thinnest sheens. |
