EarthContemplating an Arctic oil spill
The waters off northern Alaska may be “the largest oil province in the United States” after the Gulf, notes Edward Itta, a native of Barrow, Alaska. He is also mayor of the North Slope Borough, an 88,000-square-mile jurisdiction that runs across the upper part of the state. And in a September 27 videoconference with the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, he tried to impress upon the commissioners just how remote his neck of the tundra is.

ChemistryBP oil: Gulf sediment at risk, oceanographer claims
Most of BP’s spilled oil remains in the Gulf — with little sign of degrading, according to Ian MacDonald of Florida State University. And much of this surviving oil could be in sediment or on its way there, the scientist reported at a September 27 meeting in Washington, D.C.

TechPoor initial Gulf spill numbers did ‘not impact’ response
In the early weeks after the catastrophic blowout of the deep-water well in the Gulf of Mexico this spring, BP — the well’s owner — provided the government dramatically low estimates of the flow rate of oil and gas into the sea. Did telling Uncle Sam and the public that the flow rate was 1,000 barrels per day and later 5,000 barrels per day — when the actual rate was closer to 50,000 to 65,000 barrels per day — affect the spill’s management?

EarthClean out your medicine cabinet: Today!
For years, people have been chastised for pitching unused drugs into the trash, turning them into potentially toxic pollutants that can leach into the environment. On Saturday, September 25, the Drug Enforcement Administration is offering to take those drugs off our hands. For free. No questions asked.

EnvironmentGases dominate Gulf’s subsea plumes
Shipboard experiments in June show that natural gas dominates the Gulf oil plumes and that its components are the favorite choice of microbes.
