A look at how California spill compares with 1969 disaster
May 21, 2015 by Christopher Weber
An oil slick stretched across 9 miles of coastal waters Thursday after a pipeline rupture spilled thousands of gallons of sticky, stinking crude just north of Santa Barbara. Crews are working around the clock to rake, skim and vacuum it up.
The coastline was the scene of a much larger spill in 1969—the largest in U.S. waters at the time. Here are some things to know about the two spills:
VOLUME OF CRUDE
The 1969 blowout at a Union Oil Co. offshore platform dumped more than 3 million gallons of crude oil over a span of a month. Up to 30 miles of beaches were fouled.
Tuesday's pipeline break lasted about three hours. According to initial estimates, it spilled up to 105,000 gallons, with the majority of the oil remaining on land.
Up to 21,000 gallons reached the sea, early estimates show.
BIRDS, SEA LIFE
The 1969 spill killed 9,000 birds, 8.8 million barnacles, 30,000 mussels and 51,800 limpets, according to tallies by biology professor Michael Neushul of the University of California, Santa Barbara.
He and his students were unable to prove significant numbers of deaths among fish, whales, elephant seals, sea lions or plankton.
Tuesday's spill was mostly contained near one section of coastline at Refugio Beach. So far, there is no evidence of widespread harm to birds and sea life.
Other environmental impacts are still being assessed.
CALL TO ARMS
The 1969 disaster is credited with giving rise to the American environmental movement.
Groups like the Environmental Defense Center and Get Oil Out! formed in its aftermath.
That spill led to a prohibition on new offshore platforms in federal waters off California. But companies have used fracking and other techniques in an attempt to stimulate new production from old wells.
More than 7,700 gallons of oil has been raked, skimmed and vacuumed from a spill that stretched across 9 miles of California coast, just a fraction of the sticky, stinking goo that escaped from a broken pipeline, officials ...

Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving ...
