What do past spills predict for Deepwater Horizon impact?
From ANIMAL PEOPLE, June 2010:
The Deepwater Horizon oil discharge, after 62 days, was
believed by the U.S. Coast Guard to have reached a volume of as much
as 156 million gallons–making it the second worst oil disaster in
history, 15 times larger than the 1989 Exxon-Valdez oil spill in
Prince William Sound, Alaska. The Deep-water Horizon spill is
expected to reach 250 million gallons by the time BP completes
drilling four pressure relief wells in August 2010 and finally caps
the undersea gusher.
The warm waters of the Gulf of Mexico and the Carribean Sea
receive more than four times as much sunlight per year than the
Prince William Sound, however, and that translates into
exponentially greater activity by wind, waves, and microorganisms
to mitigate the effects of oil spills.
