Climate and Hydrogeological Controls on Water Tracks in Permafrost Landscapes

open access: yesReviews of Geophysics
AbstractClimate change drives disturbance in hydrology and geomorphology in terrestrial polar landscapes underlain by permafrost, yet measurements of, and theories to understand, these changes are limited. Water flowing from permafrost hillslopes to channels is often modulated by water tracks, zones of enhanced soil moisture in unchannelized ...

Two orders of wall‐to‐wall geographic data

open access: yesArea, Volume 58, Issue 1, March 2026.
Short Abstract The use of the term ‘wall‐to‐wall’ to describe geographically extensive data without any singular definition in the remote sensing and geographically related analysis. This work presents an assessment of the application of the term in the scientific literature. Abstract From personal observations of recent published works, the term “wall‐

Permafrost extent sets drainage density in the Arctic

open access: yesProceedings of the National Academy of Sciences of the United States of America
Significance In permafrost landscapes, the competition between channel and hillslope processes directly impacts the amount of stored soil organic carbon.

Forest Reorganisation After Natural Disturbance: A Synthesis

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Natural disturbances are intensifying under global change, yet a global synthesis of their effects on forest structure and composition remains lacking. We aimed to assess the prevalence of structural versus compositional changes and to identify common post‐disturbance reorganisation pathways across forest biomes.

Governance of Climate‐Induced Relocation in the US: An Exploration of Institutional Complexity

open access: yesReview of Policy Research, Volume 43, Issue 2, March 2026.
ABSTRACT Climate change has and will continue to have a profound effect on both individuals and the communities in which they reside. A pressing question is how communities forced to confront climate‐induced catastrophe—including both rapid and slow‐onset hazards—undertake the decision of how and when to relocate, particularly given the multiple scales

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, Volume 37, Issue 4, Page 1330-1352, 28 February 2026.
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 ...

Airborne measurements of methane fluxes in permafrost landscapes (AirMeth)

open access: yes, 2014
One of the most pressing questions with regard to climate feedback processes in a warming Arctic is the regional-scale greenhouse gas release from Arctic permafrost areas. The Airborne Measurements of Methane Fluxes (AIRMETH) campaigns are designed to quantitatively and spatially explicitly address this question.

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...

A Landsat based monitoring framework for permafrost landscape dynamics

open access: yes, 2016
Recent and projected future climate warming strongly affects permafrost stability over large parts of the terrestrial Arctic with local, regional and global scale consequences. The monitoring and quantification of permafrost and associated land surface changes in these areas is crucial for the analysis of hydrological and biogeochemical cycles as well ...
