An e-mail just made me shout a barrage of expletives. In a good way. Some poor intern at Marine Science Review is probably wailing in the hospital, clenching his eye sockets in pain after trawling Google Scholar for 3 days straight. The science division at Sea Web have put together what looks to be the . . . → Read More: Holy Link Fest, Batman! My cup runneth over with oil spill literature
Another disturbing paper about the BP oil spill was published this week. The new study from Wood’s Hole researchers shows lingering traces of dispersant in the deepwater oil plume that spread out for 200 miles southwest of the Macondo well head. The sampling took place over a number of months, showing that Corexit dispersant is . . . → Read More: No S*&%t Sherlock, dispersants DON’T degrade quickly

But we decided to use them anyway. Go U.S.A.! U.S.A….U.S.A. Too much oil was collecting on the surface above the wellhead, ruining any would-be attempt to kill the gushing well. But, as McNutt is keen to note, “Problem was, there was no science when you apply [chemical dispersants] in the deep sea — we didn’t . . . → Read More: “We Didn’t Know the Impacts” of Dispersants on Sea Life
Promoting microbial degradation of oil has been one of the main arguments in favor of dispersant use. Interestingly, the PWSRCAC review (covering literature from 1997-2008) did not identify any recent study that explicitly found dispersant use enhancing the biodegradation of oil. Actually, ~50% of studies found that chemical additives inhibited microbial degradation and the other . . . → Read More: Dispersants! Part III: Do dispersants really promote degradation of oil?
Part II: How toxic are dispersants? This, I suppose, is the million-dollar question. The EPA has continually insisted that the actual dispersants is less toxic than dispersed oil. Ok, oil is full of some pretty nasty compounds, and the studies do in fact back up this claim. If you spray Corexit on some shrimp, and . . . → Read More: Dispersants! Part II: Toxicity
When I don’t know enough about a subject, I tend to Google and data-mine—obsessively. So it has become with dispersants. In the wake of oil spill, this word has been thrown around, but often without any corresponding depth of information. Kind of like that cousin you always see at family parties but never manage . . . → Read More: Dispersants! A multi-part series to enlighten your brains.
