Here’s some of the latest news regarding development of the Canadian tar sands, and the aftermath of the 2010 Deepwater Horizon (BP) oil spill in the Gulf of Mexico:

From The Globe and MailCanadian academics urge moratorium on oil-sands development:

Canada should impose a moratorium on oil-sands development until Ottawa and the U.S. can fashion a joint plan that would set a carbon price and ensure all resource development is consistent with an aggressive strategy to reduce carbon emissions, a prominent group of academics say in the journal Nature.

From The Times-PicayuneDispersant chemical found in beach oil patties four years after BP Deepwater Horizon oil spill, new study says:

Traces of a chemical contained in dispersants used to break up oil during the 87-day BP Deepwater Horizon oil spill in 2010 were found in material deposited on deepwater corals six months after the spill, and in weathered oil patties on Gulf Coast beaches four years later, according to a scientific letter published online this week in Environmental Science & Technology, the peer-reviewed research journal of the American Chemical Society.

Researchers found tiny amounts of DOSS, an abbreviation of the chemical compound dioctyl sodium sulfosuccinate, in both the oil patties and deepwater sediment.

The research conducted by scientists with Haverford College in Pennsylvania and the Woods Hole Oceanographic Institution in Massachusetts raises new questions about the assumptions on how quickly two COREXIT brand dispersants disappeared after being used to break up oil into tiny droplets, said lead author Helen Kirsty White, an assistant professor of chemistry at Haverford.

From Fuel FixBP seeks return of millions in oil spill damage payments:

HOUSTON – BP asked a federal judge on Friday to recall millions of dollars in “erroneous” payments to Gulf Coast businesses under its multibillion-dollar oil spill settlement, plus interest and attorney fees.

The London oil company said “a vast number of claimants” were paid before the court wrote a new policy in May that reversed accounting rules on how certain cash-based businesses are compensated for losses related to the 2010 Gulf of Mexico oil spill.
