The Deepwater Horizon disaster in 2010 saw nearly 800 million liters of oil spilled into the Gulf of Mexico, which satellite tracking suggested covered an estimated 149,000 square kilometers. But analysis suggests that the real extent of the spill may have been 30 percent greater because much of the oil was invisible to satellites. The study also found that the oil extended much deeper than satellites had detected, with toxic concentrations 1.3 kilometers down.
