Data were analyzed to study the role of an winter ice cover for methane cycles of three different stages in the lake-lagoon-shelf transition in a region of rapidly thawing permafrost in northeast Siberia. Dissolved methane concentrations and stable carbon isotopic signature of methane as well as hyd...
