Oil Leak Update: 1000x Worse Than Rig Owner Claimed, Still Going After 14 Years
The federal government is looking into the details from the longest running oil spill in U.S. history, and it's looking far worse than the oil rig owner let on, as The New York Times reported.
The oil spill in the Gulf of Mexico received little public attention when it happened in September 2004, but it has been steadily leaking as much as 4,500 gallons a day, not three or four gallons per day as Taylor Energy Company, the rig owner, claimed, according to a new study by the National Oceanic and Atmospheric Administration (NOAA). And that's a conservative estimate, the report said.
Oil and gas have been seeping out of the leak that started 12 miles off the Louisiana coast when an underwater mudslide caused pipes to rupture and a production platform to sink during Hurricane Ivan. Taylor successfully capped nine wells, but said it couldn't cap 16.
Taylor Energy Company, which sold its assets in 2008, estimated that the leak has been minimal based on oil sheen on the surface of the water. The company argued that between 2.4 to four gallons of oil dribble out per day when it asked a federal court to release it from a cleanup order. The company's executives asserted that oil plumes from the sea floor are from oil-soaked sediment around the sunken platform and that any rising gas is from living organisms, according to The New York Times.
"The results of this study contradict these conclusions," the report, issued on Monday by NOAA and Florida State University, concluded.
In fact, the researchers directly refuted the sediment claim, stating that since the oil is only mildly biodegraded it cannot be from built-up sediment, as the AP reported.
"While it is feasible that the heavily oiled sediments in and around the erosional pit could be contributing to oil in the water column, the chemical nature and volume of oil and gas measured precludes sediments from currently being the major source of oil to the marine environment," the report says.
Using sonar technology and a newly developed "bubblometer" — a tool for analyzing oil and gas bubbles rising through the water — the researchers determined that the plumes stem from oil and gas from several wells. They also estimated that as many as 108 barrels of oil, or just over 4,500 gallons, have spilled into the Gulf daily since the underwater mudslide, as The New York Times reported.
Taylor Energy issued a statement that it wants "verifiable scientific data about the leak and a scientifically and environmentally sound solution," according to the AP. The company has also said that since the uncapped pipes are buried under so much oily and treacherous silt, stopping any leaks would do more environmental damage than letting them be.
The NOAA report comes out just as the Trump administration wants to open the entire U.S. coastline to drilling and plans to rollback safety regulations put in place after the 2010 Deepwater Horizon explosion in the Gulf of Mexico.
"This is an unresolved, ongoing leak 14 years later," said Daniel Jacobs, author of BP Blowout: Inside the Gulf Oil Disaster, as The New York Times reported. "This is yet another indication that we are not ready to expand offshore drilling."

Farms with just one or a handful of different crops encourage fewer species of pollinating and pest-controlling insects to linger, ultimately winnowing away crop yields, according to a new study.
Up to half of the detrimental impacts of the "landscape simplification" that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects, a team of scientists reported Oct. 16 in the journal Science Advances.

"Our study shows that biodiversity is essential to ensure the provision of ecosystem services and to maintain a high and stable agricultural production," Matteo Dainese, the study's lead author and a biologist at Eurac Research in Bolzano, Italy, said in a statement.
It stands to reason that, with declines in the sheer numbers of insects that ferry pollen from plant to plant and keep crop-eating pests under control, these services will wane as well. But until now, it hasn't been clear how monocultures affect the number and mix of these species or how crop yields might change as a result.
Aiming to solve these questions, Dainese and his colleagues pulled together data from 89 studies cutting across a variety of landscapes, from the tropics of Asia and Africa to the higher latitudes of northern Europe. They tabulated the number of pollinating and pest-controlling insects at these sites — both the absolute number of individuals and the number of species — along with an assessment of the ecosystem services the insects provided.
In almost all of the studies they looked at, the team found that a more diverse pool of these species translated into more pollination and greater pest control. They also showed that simplified landscapes supported fewer species of service-providing insects, which ultimately led to lower crop yields.
The researchers also looked at a third measure of the makeup of insect populations — what they called "evenness." In natural ecosystems, a handful of dominant species with many more individuals typically live alongside a higher number of rarer species. The team found as landscapes became less diverse, dominant species numbers dwindled and rare species gained ground. This resulting, more equitable mix led to less pollination (though it didn't end up affecting pest control).
"Our study provides strong empirical support for the potential benefits of new pathways to sustainable agriculture that aim to reconcile the protection of biodiversity and the production of food for increasing human populations," Ingolf Steffan-Dewenter, one of the study's authors and an animal ecologist at the University of Würzburg in Germany, said in the statement.
The scientists figure that the richness of pollinator species explains around a third of the harmful impacts of less diverse landscapes, while the richness of pest-controlling species accounts for about half of the same measure. In their view, the results of their research point to the need to protect biodiversity on and around crops in an uncertain future.
"Under future conditions with ongoing global change and more frequent extreme climate events, the value of farmland biodiversity ensuring resilience against environmental disturbances will become even more important," Steffan-Dewenter said.

Greenland had quite the summer. It rose from peaceful obscurity to global headliner as ice melted so swiftly and massively that many were left grasping for adjectives. Then, Greenland's profile was further boosted, albeit not to its delight, when President Trump expressed interest in buying it, only to be summarily dismissed by the Danish prime minister.
During that time I happened to be in East Greenland, both as an observer of the stark effects of climate change and as a witness to local dialogue about presidential real estate aspirations, polar bear migrations and Greenland's sudden emergence as a trending topic.

Heavy metals that may damage a developing brain are present in 95 percent of baby foods on the market, according to new research from the advocacy organization Healthy Babies Bright Futures (HBBF), which bills itself as an alliance of scientists, nonprofit organizations and donors trying to reduce exposures to neurotoxic chemicals during the first three years of development.

Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.
But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.
