Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O

Boreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

A novel experimental platform to monitor solid/water interfaces under freeze–thaw cycles

Journal of Microscopy, EarlyView.
Abstract We design and implement an original experimental platform resting on Atomic Force Microscopy (AFM) to capture nanoscale insights into key characteristics of solid/water interfaces subject to freeze–thaw conditions. The work is motivated by the observation that freezing and thawing underpin a variety of processes in the context of, e.g ...

Tracing recent large herbivore influence on soil carbon in permafrost and seasonally frozen Arctic ground using lipid biomarkers: a pilot study

Arctic Science
This study investigates the impact of large herbivores on soil organic matter (OM) stability in Arctic permafrost and seasonally frozen ground ecosystems, focusing on the potential preservation effect of grazing. Soil samples were collected from Siberian

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra

New Phytologist, EarlyView.
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Forecasting Climate Change Using a Multivariate Cointegrated System

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.

The Arctic Boreal Burned Area (ABBA) Product

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
The Arctic Boreal Burned Area (ABBA) dataset improves wildfire mapping in high northern latitudes, capturing over 2 million km2 of burned area between 2002 and 2022 with 87.2% accuracy. Its enhanced detection of late‐season fires and reduced errors surpass global products, enabling better climate modelling and ecological impact assessments.

Velocity estimation in GPR data based on diffraction analysis: Methodology and application to Antarctic firn

Near Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.
Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...
