Abstract

Arctic lakes and ponds can be hot spots for greenhouse gas (GHG) emissions, yet studies are scarce, particularly outside the peak summer season. Here we present GHG diffusive and ebullition flux data collected over a decade from a range of water bodies formed on an organic-rich, polygonal landscape originating from syngenetic permafrost. The GHG concentrations and flux data are supplemented with radiocarbon and stable isotope signatures of the emitted gases, together with limnological properties of the studied lakes and ponds.
