Abstract

Abstract The rates of subsea permafrost degradation and occurrence of gas-migration pathways are key factors controlling the East Siberian Arctic Shelf (ESAS) methane (CH 4 ) emissions, yet these factors still require assessment. It is thought that after inundation, permafrost-degradation rates woul...
