What is the real story about the “missing oil”. One study shows that most of the oil is gone, while another shows that there is still a whole lot of it in a mid-depth plume not visible from the surface. The answer might have been found in research announced today by Lawrence Berkeley Lab of the US Department of Energy. They found the plume alright, but they also found that microbial activity, spearheaded by a new and unclassified species, degrades oil much faster than anticipated. This degradation appears to take place without a significant level of oxygen depletion.

The study notes “Our findings show that the influx of oil profoundly altered the microbial community by significantly stimulating deep-sea psychrophilic (cold temperature) gamma-proteobacteria that are closely related to
