Understanding and quantifying the global methane (CH 4) budget is important for assessing
realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of …

Gas hydrate, a frozen, naturally‐occurring, and highly‐concentrated form of methane,
sequesters significant carbon in the global system and is stable only over a range of low …

The global methane (CH 4) budget is becoming an increasingly important component for
managing realistic pathways to mitigate climate change. This relevance, due to a shorter …

The rates of subsea permafrost degradation and occurrence of gas-migration pathways are
key factors controlling the East Siberian Arctic Shelf (ESAS) methane (CH4) emissions, yet …

The East Siberian Arctic Shelf holds large amounts of inundated carbon and methane
(CH4). Holocene warming by overlying seawater, recently fortified by anthropogenic …

This paper summarizes current understanding of the processes that determine the dynamics
of the subsea permafrost–hydrate system existing in the largest, shallowest shelf in the Arctic …

Seafloor methane release due to the thermal dissociation of gas hydrates is pervasive
across the continental margins of the Arctic Ocean. Furthermore, there is increasing …

Permafrost covers a quarter of the northern hemisphere land surface and contains twice the
amount of carbon that is currently present in the atmosphere. Future climate change is …

Methane's contribution to radiative forcing is second only to that of CO 2. Though previously
neglected, methane is now gaining increasing public attention as a GHG. At the recent …

Two areas with cold methane seeps on the outer shelf of the Laptev Sea were studied by
two interdisciplinary expeditions onboard the RV Akademik Mstislav Keldysh in August …
