"In May, scientists in the Gulf of Mexico began tracking plumes of methane and oil droplets drifting up to 30 miles from the broken [BP oil] well, at depths of 3,000 to 4,000 feet. One of those scientists was University of Georgia biogeochemist Mandy Joye, who has spent years studying hydrocarbon vents and brine seeps in the deep Gulf. She found a plume the size of Manhattan, and its methane levels were highest she had ever measured in the Gulf. As bacteria feast on spilled oil and methane, they deplete the water of oxygen; at one point Joy found oxygen levels dangerously low for life a water layer 600 feet thick, at depths where fish usually live. Since waters in the deep Gulf mix very slowly, she said, such depleted zones could persist for decades."

Student version: The 2010 oil spill in the Gulf of Mexico from one of the BP Oil Company's wells was one of the most environmentally damaging spills in the history of oil drilling. Bourne says that, according to one University of Georgia scientist, huge columns of oil and methane in the Gulf have already led to depleted oxygen supplies in the water. As a result, vast areas once home to fish may be unable to support life for years to come. (110-111) .
