Microbes may consume far more oil-spill waste than earlier thought
Date:10/20/2010

CAMBRIDGE, Mass., Oct. 20, 2010 -- Microbes living at the bottom of the Gulf of Mexico may consume far more of the gaseous waste from the Deepwater Horizon oil spill than previously thought, according to research carried out within 100 miles of the spill site.

A paper on that research, conducted before the Deepwater Horizon rig exploded six months ago today, will appear in a forthcoming issue of the journal Deep-Sea Research II. It describes the anaerobic oxidation of methane, a key component of the Gulf oil spill, by microbes living in seafloor brine pools.

"Because of the ample oil and gas reserves under the Gulf of Mexico, slow seepage is a natural part of the ecosystem," says Peter R. Girguis, associate professor of organismic and evolutionary biology at Harvard University. "Entire communities have arisen on the seafloor that depend on these seeps. Our analysis shows that within these communities, some microbes consume methane 10 to 100 times faster than we've previously realized."

Girguis is quick to note that methane is just part of what spilled from the ruptured Deepwater Horizon well for three months earlier this year, and that the rate at which methane spewed from the damaged well far exceeds the flow that microbes would ordinarily encounter in the Gulf.

Key to the work by Girguis, Harvard research scientist Scott D. Wankel, and their colleagues was the ability to use on-site mass spectrometry to obtain direct, accurate measurements of seafloor methane. It's been difficult to make such measurements because most tools don't work accurately 5,000 to 7,000 feet below the surface, where pressures can reach roughly 220 atmospheres.

Using this new technique, the scientists were able to ascertain methane concentrations in brine pools surrounding gas seeps at the bottom of the Gulf -- which were extremely high -- as well as in the water column above the pools. Combining this data with measurements of microbi
