Researchers analyzed bacterial communities exposed to Deepwater Horizon oil and identified taxa and genes associated with oil degradation and assimilation. The scientists found that Marinobacter and Alcanivorax dominated alkane-degrading communities, while Alteromonadales, Oceanospirillales, and Rhodospirillales dominated polycyclic aromatic hydrocarbon (PAH)-degrading communities.
Scientists and outreach personnel created an on-line resource that examines two major oil spills in the Gulf of Mexico: The Deepwater Horizon in the northern Gulf and the Ixtoc in the southern Gulf. Beneath the Horizon website, developed by the C-IMAGE research group and Jake Price Productions, explores these spills, the people who coped with and responded to these disasters, and expectations for recovery.
Scientists constructed a food web model using data from published studies and their field experiences to understand how specific Louisiana salt marsh organisms influenced ecosystem response to the Deepwater Horizon oil spill. The researchers found that carnivorous fishes were “critically resilient” and likely enhanced food web resilience.
Gulf-wide baseline for oil pollution monitoring complete! Marine scientists advanced academic relations between the U.S. and Cuba during an 18-day research expedition (May 8-25) off the northwest coast of the island nation.
Researchers conducted laboratory experiments on mahi-mahi embryos to determine the effects of ultraviolet radiation (UV) and oil co-exposure during different times in their development. The team observed that UV affected the success of mahi-mahi hatch in all exposure scenarios compared to controls but was highest (a 1.6- to 6-fold increase) when co-exposure occurred late in embryonic development.
Vanessa Parks compiles and analyzes data on Gulf Coast communities that explores how the Deepwater Horizon oil spill affected mental and physical health and how social factors contributed to post-disaster health outcomes.
Scientists developed and validated a high-resolution mass spectrometry method to fill data gaps in existing methods that detect the surfactant DOSS, a significant Corexit component, in sediments near the Deepwater Horizon spill site.
The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce that a new state-of-the-art scientific research vessel has been named in honor of Research Board member William “Bill” T. Hogarth. The R/V W.T Hogarth will support the research of over two dozen institutions and agencies across Florida and will be used for refined bottom mapping, metal tracing, surveying, collecting samples, and more.
The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce a new Sea Grant informational brochure just in time for the summer boating season. The one-page guide gives boaters information on how to prepare for, respond to, and report an accidental oil or fuel spill on their vessels.
Scientists analyzed the carbon composition in Seaside Sparrow tissues to learn if oil from the 2010 spill was incorporated into the terrestrial food web. The researchers found reduced radiocarbon and stable carbon concentration levels in the feathers of birds captured at oiled sites compared with birds from non-oiled sites, which is consistent with a fossil oil source.
