AUSTIN, Texas - Nearly four years after the Deepwater Horizon oil spill in the Gulf of Mexico, a new study says the disaster is far from over.
Much research remains to be done, said Dr. Doug Inkley, senior scientist for the National Wildlife Federation, but the science shows that wildlife still are feeling the impacts and the oil is not gone.
"There is oil on the bottom of the gulf, oil is washing up on the beaches and oil's still in the marshes," Inkley said. "I'm really not surprised by this, to tell you the truth. In Prince William Sound in Alaska, 25 years after the wreck of the Exxon Valdez, there are still some species that have not fully recovered - two-and-a-half decades later."
The April 20, 2010, explosion on BP's Deepwater rig killed 11 people and sent more than 4 million barrels of oil into the gulf, in the largest environmental disaster in U.S. history.
The report examined how the spill has affected more than a dozen species in the gulf. Inkley said that includes issues with oysters and tuna, loons and pelicans, sperm whales and dolphins.
"Dolphins in the heavily oiled area of Barataria Bay are still sick and dying," he said. "The evidence is stronger than ever, according to NOAA, that these deaths are connected to the oil spill - 900 dolphins since the oil spill began. If you line up those 900 dolphins from head to toe, that's one-and-a-half miles of dead dolphins."
The spill also affected five sea turtle species found in the Gulf of Mexico, all of them listed as either threatened or endangered. Pamela Plotkin, director of Texas Sea Grant, said that includes the Kemp's ridley sea turtle, which had seen its population rebound year after year until Deepwater. Now, she said, they're also being threatened by last month's spill in Galveston Bay.
"The biggest concern is the oil that has left the bay and has moved south down towards Matagorda Ilsand and the Aransas Wildlife Refuge," she said. "So, that oil that has moved offshore is going right through the migratory corridor of the Kemp's ridley sea turtle."
Up to 168,000 gallons of oil spilled in late March when a barge and a ship collided in Galveston Bay, which averages close to 300 oil spills of various sizes each year.

Recreational fishermen in New England say commercial trawlers are threatening the survival of smaller businesses relying on a healthy stock of Atlantic herring.
The small forage fish is vital to both the marine food chain and the region's economy.
Rich Hittinger, first vice president of the Rhode Island Saltwater Anglers Association, said years of overfishing depleted the population and continue to have negative effects on the ocean ecosystem.
"The predator fish, like the striped bass, they're scrounging for anything that they can eat," Hittinger observed. "And we often see fish that are long and thin because they're really not getting sufficient nutrition."
Hittinger noted anglers want the New England Fishery Management Council to reestablish a 12-mile offshore buffer zone to force large commercial trawlers out to sea and reduce conflicts with businesses closer to shore. The council is accepting public comments through April.
For more than a decade, New England anglers worked to amend the Atlantic Herring Fishery Management Plan to protect inshore areas from the effects of industrial trawling, which can ensnare massive amounts of marine life in football field-size nets. But a previous buffer zone was vacated in 2022 after a court determined the depletion of Atlantic herring could not be scientifically proven.
Jaclyn Higgins, forage fish program manager for the Theodore Roosevelt Conservation Partnership, said just 20% of a healthy Atlantic herring stock remains.
"We're hoping that we can really pinpoint what kind of spatial and temporal restrictions need to be put in place," Higgins explained. "So that we can come to a better compromise with managing the fishery."
Higgins pointed out charter businesses, bait and tackle shops, marinas, even whale-watching operators are all dependent on Atlantic herring. She added it is important their voices be heard as regulators consider new ways to manage the population and ensure all entities have access to this small but significant fish.

Colorado may soon welcome back wolverines, an animal with a reputation for its ferocity and strength nearly wiped out by trapping, poisoning and habitat loss in the early 20th century.
Last week, lawmakers introduced Senate Bill 24-171, which if passed would kickstart the process of reintroducing the carnivore as soon as 2026.
Michael Saul, Rockies and Plains program director with Defenders of Wildlife, said wolverines are native to Colorado, but just 300 or so remain in the entire lower 48, and that the Rocky Mountains may offer the best chance for their long-term survival.
"Because of the height and climate of the high Colorado mountains, Colorado is one of the best places for holding onto deep snow through the 21st century," Saul explained.
Wolverines rely on hard-packed snow at high elevations throughout the winter to store food and dig dens to raise their young, and Saul noted that stress from shrinking snowfall has led to a decline in mating numbers. Not to be confused with the similarly named wolves, wolverines are a member of the weasel family and weigh between 18 and 40 pounds.
The animal was listed as threatened under the Endangered Species Act in 2023 largely due to loss of habitat to climate change. The bill includes compensation to ranchers for any loss of livestock, but Saul said there have only been two known attacks in the past century worldwide.
"A wolverine would much rather find a deer, elk or moose that had been killed by an avalanche, and scavenge the frozen corpse, than try and hunt a sheep," he said.
Wolverines are tenacious scavengers. Their back molar teeth are turned sideways, an adaptation that allows them to tear into and crush frozen meat and bones. They can smell prey beneath 20 feet of snow, and the ferocious critter has been known to fight off animals many times their size.
"There are stories from the 19th century trappers and mountain men of wolverines picking a fight with a grizzly bear over an elk carcass, " Saul said.

A Connecticut bill would have restricted toxic pesticides called neonicotinoids - or so it seemed. The bill's newest iteration, some experts feel, is a shell of the original, without the same protections.
Joyce Leiz, executive director of the Connecticut Audubon Society, noted the new version won't ban agricultural uses, but still mentions them in the bill. She said the new version also removes a ban on using these chemicals on golf courses or for landscaping.
"Those two areas would still be able to use neonicotinoids," she said. "Golf courses in the state of Connecticut represent between 8,000 to 12,000 acres of land and are the heaviest users of neonicotinoids for grub control."
Leiz said these chemicals don't impact the grubs as much as it seems. She feels the agriculture industry and golf courses are driving the bill's changes since they've used neonicotinoids for so long. Farmers rely on seeds coated with the chemical to repel insects.
The bill is under review by the Joint Committee on Environment.
The Connecticut Audubon Society will hold a conference on neonicotinoids on Monday. Anyone interested in attending can visit ctaudobon.org for more details.
Neonicotinoids have been banned or heavily restricted in numerous areas for the harmful effects they have on wildlife. Leiz says the coated seeds, while important for farmers, are problematic for birds.
"One coated seed can kill a songbird if that bird happens to pick it up in a field," she said. "It has enough neonicotinoids to kill a songbird. And then, the spraying on lawns kills our pollinators. So, we're losing our bees. We're losing our butterflies. "
Research shows beekeepers lost more than 45% of their honeybee colonies from 2020 and 2021. In humans, these pesticides have been linked to muscle tremors, lower testosterone and birth defects such as heart or brain deformities.
