Crude oil floating in the ocean used to be a big nuisance in parts of California. It is a natural phenomenon, created by oil deposits on the ocean floor leaking into the environment. Santa Barbara was particularly famous for it.
Extraction of that oil via commercial wells greatly reduced the natural seepage, which is why there is so little crude oil floating in that ocean water today. Oil drilling actually made the water cleaner.
