Scientists measured radiocarbon levels in coastal invertebrates and fishes (such as oysters and catfish) to evaluate impacts from the 2010 oil spill on Gulf of Mexico food webs.
Scientists from Brown University and the University of Rhode Island investigated how Alcanivorax borkumensis, a dominate bacterium in marine environments that contain high hydrocarbon levels, can be supported to naturally degrade oil.
Scientists evaluated the effects of oil contamination on coastal mangrove plants. Their partially-submerged root system makes them vulnerable to pollutants. Scientists found that oil coated the mangrove roots and reduced water transport, leading to rapid plant dehydration.
Scientists studied the interactions of the oil-degrading bacterium Alcanivorax borkumensis with oil across oil-water interfaces that had varying amounts of different surfactants.
Scientists analyzed microbial communities on beaches oiled by the Deepwater Horizon spill and found taxonomic and functional changes after hydrocarbon exposure.
Scientists conducted experiments to determine the effects of hypoxia (reduced oxygen conditions), a seasonal occurrence in the northern Gulf of Mexico, and oil spill contaminants on sheepshead minnow larvae.
Two studies show that some demersal fishes living in waters likely contaminated by the Deepwater Horizon oil spill exhibited elevated hydrocarbon concentrations and experienced shifts in diet and trophic level.
Scientists simulated twenty subsurface spill scenarios, using data reflective of the Deepwater Horizon spill, and found large differences in transport predictions when model parameters included bacterial consumption (biodegradation) of oil droplets.
Scientists assessed subsurface hydrocarbon plume simulations to understand the role of released gases on plume behavior.
An international science team assessed predictions from multiple oil spill models and found that subsea dispersants used during response to a simulated accidental blowout may reduce oil droplet size by at least one order of magnitude.
