The influence of climate and hydrological variables on opposite anomaly in active-layer thickness between Eurasian and North American watersheds [PDF]

, 2013
This study not only examined the spatiotemporal variations of active-layer thickness (ALT) in permafrost regions during 1948-2006 over the terrestrial Arctic regions experiencing climate changes, but also identified the associated drivers based on ...

Hotspots, trends, and regional focus on oil or gas exploration: A bibliometric comparative study

Deep Underground Science and Engineering, EarlyView.
This paper explores the research trends in global oil and gas exploration through the bibliometric analysis of 3460 articles collected from the Web of Science database on oil and gas exploration published from 2013 to 2023. The research hotspots, objects, regional distribution, methods, and evaluation methods of oil and gas exploration are analyzed and

Analysis of the Main Factors Controlling the Formation of Subaerial Taliks, Using a One-Dimensional Mathematical Model. A Case Study for the Shestakovka River Basin (Central Yakutia)

Лëд и снег
This study presents a mathematical model of heat transfer in a subaerial talik. The model is based on the concepts presented in classical works on permafrost, as well as on the results of geological and geophysical research carried out in the Shestakovka

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

The 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.

Reconstruction and palaeoclimatic implications of Loch Lomond Readvance glaciers in the Southeast Grampians, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT The glaciation of Scotland during the Loch Lomond Stadial (LLS; 12.9–11.7 ka BP) left a distinct and well‐preserved geomorphological signature, permitting detailed reconstructions of former glaciers and palaeoclimatic conditions. However, the extent and style of glaciation in the Southeast Grampians remains poorly constrained.

Global Estimates of L-band Vegetation Optical Depth and Soil Permittivity over Snow-covered Boreal Forests and Permafrost using SMAP Satellite Data [PDF]

arXiv, 2023
This article expands the tau-omega model to properly simulate L-band microwave emission of the soil-snow-vegetation continuum through a closed-form solution of Maxwell's equations, considering the intervening dry snow layer as a loss-less medium. The feasibility and uncertainty of retrieving vegetation optical depth (VOD) and ground permittivity, given

Time-lapse capacitive resistivity imaging: a new technology concept for the monitoring of permafrost [PDF]

, 2012
The British Geological Survey, in partnership with the Universities of Sussex and Bonn, is investigating and seeking to prove a new technology concept for the non-invasive volumetric imaging and routine temporal monitoring of the thermal state of ...

Eastern Beringia and beyond: Late Wisconsinan and Holocene landscape dynamics along the Yukon Coastal Plain, Canada [PDF]

, 2012
Terrestrial permafrost archives along the Yukon Coastal Plain (northwest Canada) have recorded landscape development and environmental change since the Late Wisconsinan at the interface of unglaciated Beringia (i.e.

Permafrost thawing puts the frozen carbon at risk over the Tibetan Plateau

Science Advances, 2020
A large quantity of soil organic carbon frozen in permafrost on the Tibetan Plateau will be at risk under future climate warming. Soil organic carbon (SOC) stored in permafrost across the high-latitude/altitude Northern Hemisphere represents an important

Summer temperatures, autumn winds, and thermal structure under the ice in arctic lakes of varying morphometry

Limnology and Oceanography, EarlyView.
Abstract Ice‐covered lakes differ strongly from their ice‐free counterparts in their temperatures, heat budgets, and hydrodynamics. Nevertheless, due to a lack of detailed measurements, processes under the ice and their drivers are still understudied.
