Births Down and Deaths Up in Gulf Dolphins
Scientists are reporting a high rate of reproductive failure in dolphins exposed to oil from the Deepwater Horizon spill. The team has monitored these bottlenose dolphins in heavily oiled Barataria Bay for five years following the spill. Their findings suggest that the effects of the Deepwater Horizon oil spill will be long-lasting.
Deepwater Horizon Oil Spill Killed Large Numbers of Dolphins, Study Suggests
Large numbers of dolphins have died as a direct result of the Deepwater Horizon oil spill, new evidence suggests. Dead bottlenose dolphins stranded in the northern Gulf of Mexico since the spill have lung and adrenal gland injuries consistent with petroleum exposure, scientists have discovered.
Further Assessment Needed of Dispersants Used in Response to Oil Spills
Experts argue for further in-depth assessments of the impacts of dispersants on microorganisms to guide their use in response to future oil spills. Chemical dispersants are widely used in emergency responses to oil spills in marine environments as a means of stimulating microbial degradation of oil.
NOAA Announces Long-Term Gulf of Mexico Ecosystem Research Priorities
As part of the final version of the science plan for the NOAA RESTORE Act Science Program, NOAA announced 10 long-term research priorities in the Gulf of Mexico, including how the Gulf’s waters, natural resources, fisheries and coastal communities are all interconnected.
Sixty-Seven Years of Oil and Gas Drilling in the Gulf of Mexico
Deepwater drilling is increasing in the Gulf. Oil companies say it’s safer now, but critics say spills are inevitable.
Deepwater Disaster: Five Years On, Not Much has Changed—Including the Impulse to Drill
The nation’s costly and dangerous dependence on fossil fuel continues to endanger the lives of U.S. workers, the health of our waters, the lifeblood of coastal economies, and the survival of wildlife. Five years later, NRDC looks back on the people and places that endured the worst of the disaster, and whose lives continue to be harmed by its impact.
Is Gulf Oil Spill’s Damage Over or Still Unfolding?
Published research suggests the BP spill hurt wildlife, wetlands and Gulf marshes in countless ways, but as with virtually everything connected to the 2010 accident, scientists say it’s simply too early to tell about the long-term damage. And because the spill hit marine and estuarine systems already facing pollution and erosion, it can be difficult to document changes and isolate causes.
Dispersant Used to Clean Deepwater Horizon Spill More Toxic to Corals than the Oil
The dispersant used to remediate the 2010 Deepwater Horizon oil spill in the Gulf of Mexico is more toxic to cold-water corals at lower concentrations than the spilled oil, according to a new study.
Oil Dispersant Used in Gulf Oil Spill Causes Lung and Gill Injuries to Humans and Aquatic Animals
New research suggests that Corexit EC9500A, an oil-dispersal agent widely used in the Gulf of Mexico following the Deepwater Horizon oil spill, contributes to damage to epithelium cells within the lungs of humans and gills of marine creatures.
