Deepwater Horizon oil spill impacted bluefin tuna spawning habitat in Gulf of Mexico

The Deepwater Horizon oil spill was one of the largest environmental disasters in history, releasing roughly 4 million barrels of crude oil into the Gulf of Mexico. For Atlantic bluefin tuna, it occurred at the worst time of year, during peak spawning season, when eggs and larval fish that are particularly vulnerable to environmental stressors exist in mass quantity. In a study (click here)published in Nature: Scientific Reports, scientists from Stanford and NOAA provide the best yet analysis of how the 2010 breeding season might have been impacted by the oil spill. Although the spill encompassed a relatively small proportion of the bluefin tuna spawning grounds, which extend throughout the northern Gulf of Mexico, the authors showed the cumulative oiled tuna habitat was roughly 3.1 million square miles, representing the potential for a significant impact on eggs and larval bluefin tuna in the Gulf of Mexico.
