That Sheen in the Gulf of Mexico Is Oil from Two Years Ago

Coast Guard's tests have concluded that a "sheen" (not of the Charlie variety) spotted on September 16 on the Gulf of Mexico in the area of BP's massive spill matches from the 2010 disaster. "The exact source of the sheen is uncertain at this time but could be residual oil associated with wreckage and/or debris left on the seabed from the Deepwater Horizon incident in 2010," reads the statement released Wednesday night by the Coast Guard's Capt. Duke Walker.  The sheen, according to CNN, is about four miles long and was first spotted on a satellite. Walker says that BP and Transocean were informed that they may have to pay for the new-old oil that's showing up today. The sheen doesn't seem to be harmful, which is good since we can't get rid of it. "The sheen is not feasible to recover and does not pose a risk to the shoreline," said Walker.
