Report: Gulf Wildlife Three Years Into the Oil Disaster
Dolphins and Sea Turtles Still Dying in High Numbers
As the three-year mark of the Gulf oil disaster approaches, a new National Wildlife Federation report gives a snapshot view of six important species in the Gulf of Mexico and makes recommendations as to how we can restore their habitats and the Gulf as a whole.
"Three years after the initial explosion, the impacts of the disaster continue to unfold,” said Doug Inkley, senior scientist for the National Wildlife Federation and lead report author. "Dolphins are still dying in high numbers in the areas affected by oil. These ongoing deaths—particularly in an apex predator like the dolphin—are a strong indication that there is something amiss with the Gulf ecosystem."
Restoring a Degraded Gulf of Mexico: Wildlife and Wetlands Three Years into the Gulf Oil Disaster looks at how different species of wildlife across the northern Gulf are faring in the wake of the oil disaster:
Dolphin deaths have remained above average in the area affected by oil every month since just before the spill began. Infant dolphins were found dead at six times average rates in January and February of 2013. The National Oceanic and Atmospheric Administration (NOAA) called the dolphin die-off "unprecedented"—a year ago. While NOAA is keeping many elements of its dolphin research confidential pending the conclusion of the ongoing trial, the agency has ruled out the most common causes of previous dolphin die-offs.
More than 1,700 sea turtles were found stranded between May 2010 and November 2012—the last date for which information is available. For comparison, on average about 240 sea turtles are stranded annually.
A coral colony seven miles from the wellhead was badly damaged by oil. A recent laboratory study found that the mixture of oil and dispersant affected the ability of some coral species to build new parts of a reef.
Scientists found that the oil disaster affected the cellular function of the killifish, a common baitfish at the base of the food web. A recent laboratory study found that oil exposure can also harm the development of larger fish such as mahi mahi.
"The oil disaster highlighted the gaps in our understanding of the Gulf of Mexico," said Ian MacDonald, professor of Oceanography at Florida State University. "What frustrates me is how little has changed over the past three years. In many cases, funding for critical research has even been even been cut, limiting our understanding of the disaster’s impacts. For example, we know that some important coral communities were damaged, but funding for the necessary follow up has not been there."
The report’s release comes as BP and the other companies responsible for the disaster are on trial in federal court for violations of multiple environmental laws. The report describes different sources of restoration funding resulting from the disaster and provides initial suggestions for how this money can be used to improve the outlook for the species discussed in the report.
"Despite the public relations blitz by BP, this spill is not over," said David Muth, director of National Wildlife Federation’s Mississippi River Delta Restoration Program. "In 2012 six million pounds of tar mat and contaminated material from the BP spill were cleaned up from Louisiana’s coast. Justice will only be served when BP and its co-defendants pay to restore the wildlife and habitats of the Mississippi River Delta and the Gulf of Mexico."
Other oil disasters have taken years to reveal their full effects, and often recovery remains incomplete after decades. To date, the disaster response has focused on removing the visible oil, but little has been done to tackle the region’s long-standing habitat degradation and water quality problems—issues that were exacerbated by the oil disaster.
"I’ve always considered myself truly fortunate to make a living fishing these waters," said Ryan Lambert, owner of Cajun Fishing Adventures, a lodge and charter boat operation in Buras, Louisiana. “Right now, we have a once-in-a-lifetime opportunity to get this ecosystem back on its feet, but we need to make sure we use the money from BP’s penalties on projects that will improve the health of the Gulf in the long run. That’s the best way to restore our economy, and it is the best way to make sure our children have the opportunity to enjoy this region as we have for decades."
