The 2010 Deepwater Horizon incident highlighted new challenges and science gaps in our understanding of and ability to respond to deep-water oil releases. Of particular importance is how highly pressurized oil and gas behaves in a deep-sea environment.
The Gulf of Mexico Research Initiative (GoMRI) congratulates Dr. Samantha Joye and Dr. Wei-Jun Cai on their selection as American Geophysical Union (AGU) Fellows.
Salt marshes support commercially and culturally important species and are often subject to natural and human-caused stressors. Gaps in our knowledge of salt marsh food webs made management and restoration decisions difficult after the Deepwater Horizon spill. Jessica Johnson helps fill this gap.
Scientists conducted laboratory experiments with a simulated oil plume to assess how chemical dispersants affect a crude oil jet as it transitions into a plume under crossflow conditions.
Response decisions during Deepwater Horizon relied on forecasts of where the oil was going and when it would get there. Researchers with the CARTHE consortium have been working to improve the information that goes into making ocean transport forecasts.
Researchers combined laboratory experiments and molecular simulations to examine how two Corexit surfactants – DOSS (dioctyl sulfosuccinate) and Span 80 – individually affect oil aerosolization.
The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce a new Sea Grant informational publication that explains how researchers and response managers estimate the movement and landfall of an oil spill.
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.
