TL;DR: In this article, the vulnerability of the North American high-latitude soil organic carbon (SOC) pool to climate change has been discussed, where the authors divide the current northern highlatitude organic carbon pools into near-surface soils where SOC is affected by seasonal freeze-thaw processes and changes in moisture status, and deeper permafrost and peatland strata down to several tens of meters depth where organic carbon is usually not affected by short-term changes.

TL;DR: It is suggested that water table and temperature are dominant controls on methane flux in pristine bogs and swamps, while other processes, such as vascular transport in pristine fens, have the potential to partially override the effect of these controls in other wetland types.

TL;DR: In this article, the effects of permafrost thaw on lakes and streams in the Arctic were explored, where the authors explored the effect of both thermokarst (thawing and collapse of ice-rich permaculture) and deepening of the active layer (the surface soil layer that thaws and refreezes each year).

TL;DR: In the 831,400 km2 Yukon River basin, water discharge (Q) corrected DOC export significantly decreased during the growing season from 1978-80 to 2001-03, indicating a major shift in terrestrial to aquatic C transfer as mentioned in this paper.

TL;DR: In this article, the authors examined DOC chemical characteristics and biodegradability collected from soil pore waters and dominant vegetation species in four boreal black spruce forest sites in Alaska spanning a range of hydrologic regimes and permafrost extents.
