Biodiversity of cryopegs in permafrost [PDF]
This study describes the biodiversity of the indigenous microbial community in the sodium-chloride water brines (cryopegs) derived from ancient marine sediments and sandwiched within permafrost 100-120,000 years ago after the Arctic Ocean regression. Cryopegs remain liquid at the in situ temperature of -9 to -11 degrees C and make up the only habitat ...

How do the environmental extremes of Siberian permafrost soils shape the composition of the bacterial soil community? [PDF]
Microbial communities in permafrost soils of the Siberian Arctic are exposed to extreme environmental conditions. The soils are frozen throughout the entire year except for the short summer period, when thawing of the uppermost 20 to 50 cm of the ...

ABSTRACT Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land‐to‐ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery.

Permafrost hydrology in changing climatic conditions: seasonal variability of stable isotope composition in rivers in discontinuous permafrost [PDF]
Role of changing climatic conditions on permafrost degradation and hydrology was investigated in the transition zone between the tundra and forest ecotones at the boundary of continuous and discontinuous permafrost of the lower Yenisei River.

ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The

A new map of permafrost distribution on the Tibetan Plateau
. The Tibetan Plateau (TP) has the largest areas of permafrost terrain in the mid- and low-latitude regions of the world. Some permafrost distribution maps have been compiled but, due to limited data sources, ambiguous criteria, inadequate validation ...
