Current rates and mechanisms of subsea permafrost degradation in the East Siberian Arctic Shelf

Current rates and mechanisms of subsea permafrost degradation in the East Siberian Arctic Shelf

The rate of subsea permafrost degradation is a key factor controlling marine methane emissions in the Arctic. Here, using re-drilled boreholes, the authors show that the ice-bonded permafrost table in the near-shore East Siberian Arctic Shelf has deepened by ∼14 cm per year over the past 31–32 years...
