September 16, 2014 -- From March-December 2010 during ten research cruises covering over 105,000 square kilometers, scientists documented the fate and dynamics of Deepwater Horizon methane emissions around the blowout site. They found that methane concentrations in deepwater plumes peaked in May and early June coincident with a rapid rise in the abundance of methane-oxidizing microbes and in their activity, but then oxidation activity dropped sharply in late June.

September 2, 2014 -- In an article in the September issue of BioScience researchers describe Gulf of Mexico microbial communities in the aftermath of the 2010 Macondo blowout. The authors describe revealing population-level responses of hydrocarbon-degrading microbes to the unprecedented deepwater oil plume. The spill provided a unique opportunity to study the responses of indigenous microbial communities to a substantial injection of hydrocarbons. Read more...
August 19, 2014 -- Nature degrades surface and subsurface oil, but that process depends heavily on environmental factors and oil composition. Many different and mostly saturated hydrocarbons, also known as unresolved complex mixtures (UCMs), are typically the dominant component in weathered oil but are difficult to analyze with conventional gas chromatography. As such, there is limited information about their biodegradation. This study’s goal was to learn more about oil compounds using GCxGC to separate and identify UCMs and quantify the rate, extent, and potential cessation of their biodegradation in wet and dry sand environments.
