Evaluating permafrost definitions for global permafrost area estimates in CMIP6 climate models [PDF]
Environmental Research Letters, 2023 Global permafrost regions are undergoing significant changes due to global warming, whose assessments often rely on permafrost extent estimates derived from climate model simulations.

Are permafrost microorganisms as old as permafrost?
FEMS Microbiology Ecology, 2021 ABSTRACT Permafrost describes the condition of earth material (sand, ground, organic matter, etc.) cemented by ice when its temperature remains at or below 0°C continuously for longer than 2 years. Evidently, permafrost is as old as the time passed from freezing of the earth material.

Bioinformation, 2022 Thawing permafrost is a serious and worrisome threat to the environment, because it releases trapped heavy metals and greenhouse gasses. Thawing permafrost is also a health threat because, in addition to releasing these noxious gasses, thawing permafrost may free novel and undiscovered antibiotic-resistant bacteria, viruses, fungi and parasites among a

Challenges of Hydrological Engineering Design in Degrading Permafrost Environment of Russia
Energies, 2022 The study shows that the current network of hydrometeorological observation in the permafrost zone of Russia is insufficient to provide data for the statistical approaches adopted at the state level for engineering surveys and calculations.

Long-Term Variability in Ground Thermal State in Central Yakutia’s Tuymaada Valley
Land, 2021 This paper presents the results of long-term temperature monitoring at the Yakutsk and Zeleny Lug stations, which are experimental sites, for the thermal state of valley permafrost landscapes under the conditions of modern climate warming. An analysis of

Lake water and talik groundwater interaction in continuous permafrost, Central Yakutia [PDF]
E3S Web of Conferences, 2019 Structural features of a lake talik associated with eolian relief are discussed. Analysis of hydrochemical and hydrological data for 2010-2017 showed that talik groundwater feeds lake and maintains perennial outflow from the lake.
