Tar Balls: The End State

Abstract

Tar balls are frequently reported as an indicator of the extent of the impact of a spill incident. The determination of the density of tar balls is basic to the shoreline cleanup assessment team (SCAT) process, and is frequently used by the media as an indication of oil pollution. The processes involved in the evolution of tar balls are not well understood and there is a paucity of literature on the science of tar ball formation.
