BPWHAT HAVE YOU DONE?DeepWater Horizon Oil Spill
TimelineDeepwater Horizon floating rig exploratory drilling 50 miles southeast of Venicewater nearly 1 mile deep only 40-50 rigs in Gulf drilling this deepApril 20, 2010 explosion methane gasApril 22, 2010 rig topples, oil begins to leak from well in sea floorBlow-out preventer failedThree leaks, one has been sealed
Current situationAs of ???????????? gallons of oil have been released into the gulf. Exxon Valdez in 1989 was 11 million gallonsAttempted to place large funnel over leak on Saturday 5/8 Gas-water crystals cloggedMitigation: booms, skimming, burning, dispersants (bad weather disrupts)Oil started showing up on shore over the weekend
What next for BP?As of July 15 the leak has been capped. Future ???????? $$$$$$
BIODEGRADATION OF OIL BYBACTERIA
BACTERIA AND MICROBES ARE THE ONLY THINGS THAT WILL ULTIMATELY CLEAN UP (NOT JUST MOVE AROUND) THE ONGOING OIL SPILL IN THE GULF OF MEXICO
There are billions of hydrocarbon chewing microbes
BACTERIA ARE ABLE TO MAKE THEIR OWN SURFACTANT ( reduces surface tension)
DispersantsSeparates the oil into smaller dropletsDispersed throughout the water columnPrevent surface slick affects beaches, marshes, animals immediate damageDoes not destroy or eliminate oil dilutes and alters until natural degradation Where does it go? complex currents, water vs sedimentWhat does it do? food chain, toxicity
