Fast response of fungal and prokaryotic communities to climate change manipulation in two contrasting tundra soils

open access: yesEnvironmental Microbiome, 2019
Background Climate models predict substantial changes in temperature and precipitation patterns across Arctic regions, including increased winter precipitation as snow in the near future.

Surface displacement revealed by L-band InSAR analysis in the Mayya area, Central Yakutia, underlain by continuous permafrost

open access: yesEarth, Planets and Space, 2020
Recent increases in global temperature have stimulated permafrost degradation associated with landform deformation caused by the melting of excess ground ice (thermokarst).

Evaluating permafrost definitions for global permafrost area estimates in CMIP6 climate models

open access: yesEnvironmental 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.

Spatial and Temporal Variations in Active Layer Thawing and Their Implication on Runoff Generation in Peat-Covered Permafrost Terrain [PDF]

open access: yes, 2009
The distribution of frost table depths on a peat-covered permafrost slope was examined in a discontinuous permafrost region in northern Canada over 4 consecutive years at a variety of spatial scales, to elucidate the role of active layer development on ...

Linking Relationship of Ecosystem Service Supply and Demand Into Sustainable Development Goals (SDGs)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Ecosystem services (ES) play a crucial role in sustainable development. We systematically assessed the spatial and temporal dynamics of ecosystem service supply (ES‐s) and demand (ES‐d) in China from 1990 to 2020 by using a supply–demand matrix integrated with land use/cover data. The findings indicate that in 2020, grasslands accounted for 28.

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Brief communication: Testing a portable Bullard-type temperature lance confirms highly spatially heterogeneous sediment temperatures under shallow bodies of water in the Arctic [PDF]

open access: yesThe Cryosphere
The thermal regime in the sediment column below shallow bodies of water in Arctic permafrost controls benthic habitats and permafrost stability. We present a robust, portable device that measures detailed temperature–depth profiles of the near-surface ...

Distinguishing ice-rich and ice-poor permafrost to map ground temperatures and ground ice occurrence in the Swiss Alps [PDF]

open access: yesThe Cryosphere, 2019
Mountain permafrost is invisible, and mapping it is still a challenge. Available permafrost distribution maps often overestimate the permafrost extent and include large permafrost-free areas in their permafrost zonation.

Respiration of aged soil carbon during fall in permafrost peatlands enhanced by active layer deepening following wildfire but limited following thermokarst [PDF]

open access: yes, 2018
Permafrost peatlands store globally significant amounts of soil organic carbon (SOC) that may be vulnerable to climate change. Permafrost thaw exposes deeper, older SOC to microbial activity, but SOC vulnerability to mineralization and release as carbon ...
