Riassunto:Title screen
Among Arctic carbon reservoirs, subsea permafrost, hydrates, and associated methane (CH4) deposits are the most worrisome owing to high heat transfer from rapidly warming shallow Arctic seas. The East Siberian Arctic Shelf is a big portion of the Arctic shelf and hosts over 80% of current subsea permafrost and along with it, unique Arctic shallow CH4 hydrates. Degradation of subsea permafrost results in increasing permeability for gaseous CH4 long preserved in seabed deposits within and beneath permafrost. Nevertheless, knowledge about the present thermal state of subsea permafrost is mainly based on modeling results, which are controversial. In that sense, actual values of thermal conductivity are crucially needed. In this report, we represent the first results of in situ measurements of the major sediment core thermodynamically parameters in the ESAS.
