Oil pollution is drifting into marine protected areas, report finds

Oil slicks from vessels and offshore oil operations repeatedly drifted into marine protected areas around the world between 2022 and 2025, a new analysis has found. The report raises concerns for important habitats for a variety of marine life, including whales, dolphins, and sea turtles. Researchers from SkyTruth, a U.S.-based nonprofit that tracks oil pollution using satellite imagery, detected dozens of slicks covering hundreds of square kilometers in protected waters globally. “We’re seeing persistent, repeated, chronic oil pollution in many parts of the ocean from shipping and offshore oil and gas operations,” SkyTruth CEO John Amos told Mongabay by phone. “Wind and current blow them around out in the ocean, so even if the pollution event that occurs is outside a marine protected area, that pollution could drift into the protected area.” Map by Emilie Languedoc/Mongabay. The worst oil pollution in an MPA was recorded along the Atlantic coast of the Republic of Congo’s Conkouati-Douli National Park. SkyTruth recorded 27 oil slicks covering 880 square kilometers (340 square miles) of the park’s waters. The slicks likely came from three offshore oil platforms located outside the marine park, according to the report. The area is home to sharks, rays, dolphins, whales, and manatees. Leatherback (Dermochelys coriacea) and olive ridley (Lepidochelys olivacea) sea turtles also nest there. In the Mediterranean Sea, roughly 417 km2 (161 mi2) of oil slicks covered sections of two important marine protected areas. Spain’s Mediterranean Cetacean Migration Corridor registered 45 slicks, all from vessels, the report notes. The…This article was originally published on Mongabay
