Sunlight Reduces Effectiveness of Dispersants Used in Oil Spills

A airplane sprays chemical dispersants on an oil slick during the 2010 Deepwater Horizon oil spill. Two new studies have shown that sunlight transforms oil spills on the ocean surface more significantly and quickly than previously thought. The phenomenon considerably limits the effectiveness of chemical dispersants, which are designed to break up floating oil and reduce the amount of oil that reaches coastlines.

Radioactivity Lingers from 1946-1958 Nuclear Bomb Tests

Scientists have found lingering radioactivity in the lagoons of remote Marshall Island atolls in the Pacific Ocean where the United States conducted 66 nuclear weapons tests in the 1940s and 1950s.

Researchers Assess Radioactivity Released to the Ocean from the Fukushima Dai-Ichi Nuclear Power Facility

The impact on the ocean of releases of radioactivity from the Fukushima nuclear power plants remains unclear. But a new study by U.S. and Japanese researchers analyzes the levels of radioactivity discharged from the facility in the first four months after the accident and draws some basic conclusions about the history of contaminant releases to the ocean.
