A study using source-diagnostic signatures of three different isotopic forms of dissolved methane in the waters of the East Siberian Arctic Shelf suggests that the origin of the elevated methane, which warms the climate, is likely from an old, deep reservoir; uncovering the sources of subsea methane release could help forecast future emissions, according to the authors.
