Six years after BP’s offshore oil rig exploded in the Gulf of Mexico, media outlets are detailing new research that shows how the spill continues to harm wildlife and the local environment. These reports stand in stark contrast to the countless times conservative media defended BP and downplayed the disaster’s catastrophic impacts.
The Deepwater Horizon drilling rig exploded on April 20, 2010, killing 11 workers and causing the worst oil spill in U.S. history, which devastated the region’s ecosystem and economy. The magnitude of the spill was so great that new evidence of its long-lasting impacts continues to surface six years later in research and media coverage.
US News & World Report: The BP Spill Is Responsible For A “Die-Off Of Baby Dolphins.” On April 12, U.S. News & World Report covered a recent study by the National Oceanic and Atmospheric Administration (NOAA) finding that “[m]ore than 170 stillborn and juvenile bottlenose dolphins found stranded in recent years along the Gulf Coast were likely killed by oil from the April 2010 explosion of the Deepwater Horizon drilling rig.” The article further reported:
Scientists observed a spike in stranded stillborn and juvenile dolphins along Alabama, Mississippi and Louisiana's shores from 2010 to 2013. Researchers now believe the dolphins' mothers suffered chronic illnesses after being exposed to oil from the Deepwater Horizon spill off the coast of Louisiana.
"Our new findings add to the mounting evidence from peer-reviewed studies that exposure to petroleum compounds following the Deepwater Horizon oil spill severely harmed the reproductive health of dolphin living in the oil spill footprint in the northern Gulf of Mexico," veterinarian and study co-author Teri Rowles, head of NOAA's Marine Mammal Health and Stranding Response Program, said in a statement.
The oil spill's long-term effects on dolphins' reproduction remain unclear.
More than 1,400 dead dolphins and whales – collectively referred to as cetaceans – have washed up on the Gulf's shores since the disaster, far more than the average before the spill. Federal officials have declared an "unusual mortality event" for cetaceans in the region, which remains ongoing.
The Tampa Tribune: Spill May Have Long-Term Effects On Fish Health. The Tampa Tribune reported on April 18 that researchers at the University of South Florida (USF) are just “beginning to chart the long-term effects of one of the biggest environmental disasters in history.” For one, the scientists are examining the long-term effects on both shallow and deepwater fish:
No contaminated fish have made their way to the seafood market, said Steven Murawski, a professor of population dynamics and marine ecosystem analysis at USF, but researchers are still trying to figure out how many generations of fish may be affected by the spill.
Now, researchers are working to determine if the spill has had any long-term effect on fish DNA by attempting to grow second generations of affected fish at Mote Marine in Sarasota. The production of baby red snapper has fallen in the eastern gulf, for example, but researchers can’t yet say if that’s a result of the spill or natural cycling.
The fish can metabolize some oil components and were only exposed to lower, sub-lethal concentrations of toxins because the oil that escaped the well was a light form of crude, but there are still questions surrounding the effects of long-term exposure, [USF scientist David] Hollander said.
“It’s like if you stick your head in a paint can and smell the fumes you would get a headache, but what are the results if you painted a room and went to sleep in it so you’re breathing those fumes for a lot longer?” Hollander said.
National Geographic: The Oil Spill Was Even Bigger Than Previously Thought. On April 20, National Geographic reported on a new study finding that the BP oil spill was even bigger than previously thought -- 19 percent bigger, to be exact. From National Geographic:
Scientists from the federal government's National Oceanic and Atmospheric Administration and several private research companies found oil along 1,313 miles (2,113 kilometers) out of 5,930 miles (9,545 kilometers) of surveyed shoreline after the spill, an increase of 19 percent from previously published estimates. That makes the disaster the largest marine oil spill in history by length of shoreline oiled, the team reported in the journal Marine Pollution Bulletin.
The scientists found the majority of the oiling in Louisiana, with significant oiling in Mississippi, Alabama, Florida, and, to a lesser extent, Texas.
National Geographic also reported that approximately “30 percent of the oil thought to have been spilled is still unaccounted for,” adding that some scientists think “it must have sunk to the ocean bottom, where it may be harming communities there.”
