Revised classification of glaciofluvial landforms in the Finnish sector of the Fennoscandian Ice Sheet

Boreas, Volume 55, Issue 3, Page 702-716, July 2026.
Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

From Snowferner to no ferner: The deglaciation of Zugspitzplatt

Annals of Glaciology
The Zugspitzplatt represents a key high-alpine reference landscape in German geography. Located below the Zugspitze, Germany’s highest peak, it still hosts some of the country’s small remaining glacier ice reserves.

Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

Boreas, Volume 55, Issue 3, Page 670-701, July 2026.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

Post-glacial melt generation in Southern Chile and the development of the Carrán-Los Venados Volcanic Field (40°20'S)

Volcanica
The Carrán-Los Venados volcanic field in southern Chile comprises small basaltic eruption centres of Holocene to historical ages. These centres are atop extensive, basaltic flows that erupted during late glacial or early postglacial times (< 14ka ...

An overview of Mass Accumulation Rates in key Polish loess–palaeosol sequences derived from luminescence chronologies

Boreas, Volume 55, Issue 3, Page 835-845, July 2026.
Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

Insect Conservation and Diversity, Volume 19, Issue 4, Page 918-932, July 2026.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide

Genomic Structure and Demographic History of the Brown Fur Seal: From the Ice Age to Current Isolation

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Arctocephalus pusillus (the brown fur seal) has historically experienced population fluctuations associated with glacial cycles and anthropogenic exploitation. Previous mitochondrial DNA (mtDNA) and microsatellite analyses suggested a post‐glacial population expansion in A.

Geology of the central uplift of the Kamestastin Lake impact structure, Labrador, Canada

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1417-1433, July 2026.
Abstract The ~28 km Kamestastin (Mistastin) Lake impact structure is a relatively well‐preserved and well‐exposed complex impact structure. The central uplift of this structure is accessible as two islands in the middle of Kamestastin Lake. We present an updated, detailed geological map and description of Horseshoe and Bullseye islands that provides ...

A Mountain Glacier Perspective on the Bipolar Seesaw

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract A global record of mountain glacier terminations during the last deglaciation (∼19–11 ka) dated by a large, uncurated data set of cosmogenic‐nuclide exposure ages highlights a statistically significant asynchrony in termination ages between the Northern and Southern Hemispheres.

Global Glacial Rock Weathering Signature Depends on Competing Contributions From Ice Sheets and Alpine Glaciers

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Rock weathering influences Earth's atmosphere and climate. The dissolution of silicate minerals draws down atmospheric CO2 while sulfide oxidation coupled with carbonate dissolution releases CO2. Alpine glacier rock weathering causes high sulfide oxidation and carbonate dissolution.
