Oil slicks reached marine protected areas worldwide from 2022 to 2025
Oil slicks from ships and offshore oil operations reached protected waters worldwide between 2022 and 2025, according to an analysis by SkyTruth, a nonprofit that tracks oil pollution with satellite images.
The analysis detected dozens of slicks covering hundreds of square kilometres in marine protected areas.
Pollution can drift into protected waters as winds and currents carry it beyond its source, even when the ships or oil platforms are outside the boundaries.
The most affected area was the marine part of Conkouati-Douli National Park on the Republic of Congo’s Atlantic coast, where 27 slicks covered 880 square kilometres.
The contamination threatens habitats for marine life, including whales, dolphins, sharks, rays, manatees and nesting sea turtles.
Oil can harm organisms and contaminants can move up the food chain, but the effects of long-term, low-level exposure are less understood.
The findings raise concerns about whether protected areas are monitored and managed well enough to limit pollution; no specific next steps were stated.
Oil slicks from vessels and offshore oil operations drifted into marine protected areas worldwide between 2022 and 2025, a new analysis found.
Researchers from SkyTruth detected dozens of slicks covering hundreds of square kilometres in protected waters.
The worst recorded pollution was in the Republic of Congo’s Conkouati-Douli National Park, where 27 slicks covered 880 square kilometres of water.
The report warns that pollution can reach protected waters from sources outside their boundaries.
The effects of chronic, low-level exposure to oil pollution are less well understood than acute toxicity.
- Who

- When
- Between 2022 and 2025.
- Where
- Marine protected areas around the world, including sites in the Republic of Congo, the Mediterranean Sea and the Black Sea.
- Why
- Not stated

What people are saying
We’re seeing persistent, repeated, chronic oil pollution in many parts of the ocean from shipping and offshore oil and gas operations
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.
Fundamentally, oil is toxic to marine life
