The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and
human/cultural systems that may be irreversible on century time scales and have the …

Carbon is one of the key elements in organisms and non-living compounds on Earth.
Carbon dioxide and methane are important greenhouse gases in the atmosphere, dissolved …

Remobilization to the atmosphere of only a small fraction of the methane held in East
Siberian Arctic Shelf (ESAS) sediments could trigger abrupt climate warming, yet it is …

Sustained release of methane (CH4) to the atmosphere from thawing Arctic permafrost may
be a positive and significant feedback to climate warming. Atmospheric venting of CH4 from …

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 …

Coastal salt marshes are sensitive to global climate change and may play an important role
in mitigating global warming. To evaluate the impacts of Spartina alterniflora invasion on …

A methane surplus relative to the atmospheric equilibrium is a frequently observed feature of
ocean surface water. Despite the common fact that biological processes are responsible for …

The East Siberian Arctic Shelf (ESAS), which includes the Laptev Sea, the East Siberian
Sea, and the Russian part of the Chukchi Sea, has not been considered to be a methane …

Offshore permafrost plays a role in the global climate system, but observations of permafrost
thickness, state, and composition are limited to specific regions. The current global …

This study provides new estimates for the global offshore methane hydrate inventory formed
due to microbial CH4 production under Quaternary and Holocene boundary conditions. A …
