Satellites detect methane plume in Nord Stream leak

Paris (ESA) Oct 11, 2022

Following unusual seismic disturbances in the Baltic Sea, several leaks were discovered last week in the underwater Nord Stream 1 and 2 gas pipelines, near Denmark and Sweden. Neither pipeline was transporting gas at the time of the blasts, but they still contained pressurised methane - the main component of natural gas - which spewed out producing a wide stream of bubbles on the sea surface.
