Article Synopsis
- * New research indicates that the ice-bonded permafrost in the ESAS has been moving downward by approximately 14 cm each year over the last 31-32 years, contradicting earlier beliefs about long-term stability post-inundation.
- * The presence of thermokarst patterns and gas migration suggests ongoing changes in the subsea environment, highlighting the need to understand permafrost degradation to predict future methane release accurately.
Sustained release of methane (CH(4)) to the atmosphere from thawing Arctic permafrost may be a positive and significant feedback to climate warming. Atmospheric venting of CH(4) from the East Siberian Arctic Shelf (ESAS) was recently reported to be on par with flux from the Arctic tundra; however, the future scale of these releases remains unclear. Here, based on results of our latest observations, we show that CH(4) emissions from this shelf are likely to be determined by the state of subsea permafrost degradation.
