First Study of Dispersants in Gulf Spill Suggests a Prolonged Deepwater Fate

To combat last year’s Deepwater Horizon oil spill, nearly 800,000 gallons of chemical dispersant were injected directly into the oil and gas flow coming out of the wellhead nearly one mile deep in the Gulf of Mexico. Now, as scientists begin to assess how well the strategy worked at breaking up oil droplets, Woods Hole Oceanographic Institution (WHOI) chemist Elizabeth B. Kujawinski and her colleagues report that a major component of the dispersant itself was contained within an oil-gas-laden plume in the deep ocean and had still not degraded some three months after it was applied.

While the results suggest the dispersant did mingle with the oil and gas flowing from the mile-deep wellhead, they also raise questions about what impact the deep-water residue of oil and dispersant—which some say has its own toxic effects—might have had on environment and marine life in the Gulf.

Gainesville, Fla.— A team of U.S. Geological Survey (USGS) and academic scientists are analyzing samples of coral and surrounding sediments from an area damaged near the Deepwater Horizon site in the Gulf of Mexico. (more…)

BP Returns to Profit, Estimates Oil Spill at $40 Billion

Energy giant BP announced a return to profit on Tuesday but revealed new shock estimates for the cost of its Gulf of Mexico oil spill, putting the expected bill at close to $40 billion.

The new figure is far higher than expected. BP said it had taken an additional charge of $7.7 billion during the third quarter, bringing the company’s own total estimated clean-up and legal costs to $39.9 billion. (more…)

BP to Pay $4,300 for Every Barrel of Spilled Oil

The scandal around the oil spilt into the Gulf of Mexico does not subside. On Thursday, the information was released that U.S. authorities are preparing a lawsuit against the owner of the exploded BP platform, demanding compensation for damage caused by the leakage. Fines can reach $4,300 for each barrel of oil spilt in the waters of the Gulf, i.e., a total of approximately $17.6 billion. (more…)

Study Shows Deepwater Oil Plume in Gulf Degraded by Microbes

In the aftermath of the explosion of BP’s Deepwater Horizon drilling rig in the Gulf of Mexico, a dispersed oil plume was formed at a depth between 3,600 and 4,000 feet and extending some 10 miles out from the wellhead. An intensive study by scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) found that microbial activity, spearheaded by a new and unclassified species, degrades oil much faster than anticipated. This degradation appears to take place without a significant level of oxygen depletion.

Deep Plumes of Oil Could Cause Dead Zones in the Gulf

WASHINGTON — A new simulation of oil and methane leaked into the Gulf of Mexico suggests that deep hypoxic zones or “dead zones” could form near the source of the pollution.

The research investigates five scenarios of oil and methane plumes at different depths and incorporates an estimated rate of flow from the Deepwater Horizon spill, which released oil and methane gas into the Gulf from April to mid July of this year.

Scientists at the Woods Hole Oceanographic Institution (WHOI) have detected a plume of hydrocarbons that is at least 22 miles long and more than 3,000 feet below the surface of the Gulf of Mexico, a residue of the BP Deepwater Horizon oil spill.
