Abstract
Abstract An oil pollution control apparatus that isolates a portion of a substantial body of water. The portion isolated extends from above the surface to near the bottom of the body of water. A structural example is a vertical caisson with its base extending into the bottom of the body of water and with openings just above that bottom to permit circulation of the water at that level.
