Some info on drilling off of Santa Barbara:
"Oil is still so plentiful in the region that it often bubbles uncontrollably to the surface, and shows up in the form of tar globules on some of the area's beaches."
"Allen is the president of a group called Stop Oil Seeps, which argues that additional offshore drilling could be used to prevent oil from bubbling up on to beaches."
"Natural seepage alone over a four-year period amounts to roughly the same amount of oil that spilled from the Exxon Valdez incident in Alaska in 1989."
