Thermokarst

  1. Microbial methane release identified in inner Laptev Sea subsea permafrost
    Triple-isotopic analysis reveals old microbial methane from subsea permafrost drives methane release in the inner Laptev Sea, contrasting with thermogenic sources elsewhere on the Arctic shelf.
  2. Old dissolved carbon from permafrost thaw accumulates in Siberian lakes
    Study reveals that up to 75% of dissolved organic carbon in Siberian thermokarst lakes originates from permafrost thaw, yet this ancient carbon accumulates rather than rapidly converting to.
