Microbial Communities Responding to Deep-Sea Hydrocarbon Spills
The 2010 Deepwater Horizon oil spill in the Gulf of Mexico can be considered the world’s first deep-sea hydrocarbon spill. Deep-sea hydrocarbon spills occur in a different setting than surface oil spills, and the organisms that respond must be adapted to this low-temperature, high-pressure environment. The hydrocarbon composition can also be quite different than at the sea surface, with high concentrations of dissolved hydrocarbons, including natural gas, and suspended droplets of petroleum. We discuss the bacteria that may respond to these spills and factors that affect their abundance, based on data collected during the Deepwater Horizon spill and in microcosm experiments in the following years.
