L'immensa distesa di petrolio

A High Volume Open Sea Skimming System (HOSS) is used to skim oil in the Gulf of Mexico 28 April 2010. A total of 849,954 gallons of oil-water mix have been collected during the clean up and recovery operations after an explosion aboard a British Petroleum oil drilling rig resulted in a major leak. Staging areas are being set up along the Gulf Coast to actively identify, target and protect environmentally and economically sensitive areas.
