Ten years after BP\u0026#039;s Deepwater Horizon disaster sent hundreds of millions of gallons of oil across the Gulf of Mexico, researchers say the reach of the damage was far more significant than previously thought.In a study published Wednesday in Science, Claire Paris-Limouzy and Igal Berenshtein of the University of Miami revealed that a significant amount of oil was never picked up in satellite images or captured by barriers that were meant to stop the spread.\u0022Our results change established perceptions about the consequences of oil spills by showing that toxic and invisible oil can extend beyond the satellite footprint at potentially lethal and sub-lethal concentrations to a wide range of wildlife in the Gulf of Mexico,\u0022 said Paris-Limouzy.The \u0022invisible oil\u0022 spread across an area roughly 30% larger than the 92,500 square miles experts previously believed it had reached, the study says.\u0022Researchers dubbed it \u0026#039;invisible oil,\u0026#039; concentrated below the water’s surface and toxic enough to destroy 50 percent of the marine life it encountered.\u0022 https://t.co/NlXYNsDiq2— Wallace McKelvey (@wjmckelvey) February 12, 2020\u0022I think it kind of changes the way you think about oil spills,\u0022 Berenshtein told the Washington Post. \u0022People have to change the way they see this so that they know there\u0026#039;s this invisible and toxic component of oil that changes marine life.\u0022The ocean protection group Blue Frontier Campaign expressed \u0022disgust\u0022 at the revelation—but not surprise.Are we surprised, no. disgusted, yes. Time to get off fossil fuel and on to renewables. Sea Party 2020!https://t.co/mdjYVchv6t— Blue Frontier Campaign (@Blue_Frontier) February 12, 2020Since the 2010 blowout and platform explosion, which killed 11 people, scientists have estimated that the disaster spewed 210 million gallons of oil over the course of five months, with oil reaching Florida and Texas.Much of the spilled oil that Berenshtein and Paris-Limouzy detected in their research, using a model that allowed them to trace oil in the Gulf from its source, spread below the water\u0026#039;s surface and became toxic enough over time to destroy 50% of the marine life it came across.\u0026nbsp;\u0022When you have oil combined with ultraviolent sunlight it becomes two times more toxic than oil alone,\u0022 Paris-Limouzy told the Post. \u0022Oil becomes toxic at very low concentrations.\u0022Experts vastly underestimated the extent to which marine life was harmed, the researchers said.The research was released as the Trump administration prepares to open up the Arctic, Atlantic, and Pacific Oceans to oil and gas leases and to expand leasing in the Gulf.\u0022Time to get off fossil fuel and on to renewables,\u0022 wrote the Blue Frontier Campaign.
