Spatiotemporal variability of surface-based temperature inversions in high-latitude northcentral Yukon valleys utilizing a dense network of elevation transects
Surface-based temperature inversions (SBIs) strongly influence air temperature variability in high-latitude mountains, yet their spatial structure remains poorly resolved. To address this gap, a dense network of air temperature sensors was deployed and elevational transect analysis (ETA) was…

Validation of the SNOWPACK model and reconstruction of multidecade snow climatology at Ram Mountain (Alberta, Canada) forced with NARR data
In remote Canada, sparse meteorological stations hinder reliable snow data collection, especially for assessing historical records. Yet, these data are crucial to evaluate the effect of climate change on ecosystems and species. Changes in snow cover influence wildlife ecology and can impact body…

The Mammoth fauna as a paleontological characteristic of the Yedoma Ice Complex of Bol’shoy Lyakhovsky Island (New Siberian Islands, Eastern Arctic Siberia)
This article focuses on paleozoological characteristics of Yedoma Ice Complex deposits. It provides a comprehensive and detailed description of the mammoth fauna collection assembled by the Russian–German expedition for the “Laptev Sea System” project from the famous Western Beringia locality…

The geoecological development of soil microbial communities following glacier retreat
The retreat of glaciers and ice sheets since the end of the Little Ice Age has exposed proglacial margins that rapidly develop new ecosystems. These areas are quickly colonized by soil microbes (Bacteria, Archaea), which are less constrained by nutrient scarcity and disturbance than higher…

Geochronology of the Upper Ice Complex (Yedoma) exposed in the Batagay Megaslump, East Siberia
The Batagay Megaslump in eastern Siberia exposes one of the oldest permafrost archives and provides insights into Beringian paleoenvironments. However, its geochronology calls for improvement given known difficulties with permafrost dating and current developments in dating techniques. Here, we…

Rock glaciers in the Hindu Kush Himalaya: A regional synthesis
Rock glaciers are cryospheric landforms in high-mountain regions and indicators of permafrost occurrence and change under accelerating climate warming. This review synthesizes 67 peer-reviewed studies on rock glaciers across the Hindu Kush Himalaya (HKH) published between 1970 and 2024 to assess…

Chronology, cryostratigraphy, and palaeoenvironmental evidence from the CRREL Permafrost Tunnel, Alaska
The Cold Regions Research and Engineering Laboratory Permafrost Tunnel (CRREL Tunnel) in Alaska is one of the best studied Yedoma sequences in North America and is an exceptional site for understanding ice-rich, syngenetic permafrost. Here, we present cryostratigraphy, chronology, and stable…

Interpreting summit elevations on Mount Rainier: Contextualizing ice-surface change, bedrock elevation, and geodetic frameworks
Recent work has documented measurable changes in the elevation of ice-capped summits across the western United States, including Mount Rainier. At Mount Rainier, comparisons between mid-20th century survey data and modern GNSS measurements indicate a decrease in the elevation of the highest point…

Active and transitional rock glaciers above the 0°C mean annual air temperature isotherm in the La Sal Mountains, Utah, USA
Rock glaciers are common features in alpine environments that play an important role in hydrology and landscape evolution. We use satellite-based radar interferometry, topographic data, and optical imagery to identify and characterize rock glacier motion in the La Sal Mountains, Utah, USA, from…

Climate predicts disjunct arctic-alpine plant species richness and abundance along Lake Superior shorelines better than local habitat
Climate refugia can serve as remnant habitat or stepping stones for species dispersal under climate warming. Lake Superior serves as a model system for understanding lake-mediated cooling, as its cool water temperatures and wave action have maintained shoreline habitats suitable for disjunct…

Sediment connectivity evolution in three deglaciating Alpine catchments since the Little Ice Age: A graph-based reconstruction
Climate-driven glacier retreat is reorganizing sediment cascades across Alpine catchments. However, what remains poorly quantified is how their structural connectivity—the spatial configuration of landforms and pathways along which sediment can be transferred—evolves over deglaciation timescales…

Association of thermally-labile organic carbon with iron-bearing minerals in deep sediments of a small, Arctic clearwater lake
The stabilization and persistence of organic carbon (OC) in soils and sediments is thought to be governed in large part by association with mineral matrices, especially reactive iron (Fe) phases. However, the role of these organo-mineral interactions has not been fully evaluated in lake sediments…

Spatiotemporal landscape dynamics drive organic matter mobilization and degradation in thermokarst terrain of the southern continuous permafrost zone
The permafrost carbon cycle in Arctic coastal plains is strongly affected by abrupt thaw processes such as lake and hillslope thermokarst, which are expected to intensify under continued climate warming. Organic matter (OM) degradation may increase if taliks beneath drained lake basins (DLBs) fail…

The peculiar case of glacier-transported glass bottles at Piz Murtèl, Swiss Alps
Glacier ice flow not only transports eroded rock material, but can also mobilize remnants of previous touristic activities, linking physical environment with human exploitation of mountains. Here, we investigate the transport and deposition of bottles and cans on a small, rapidly shrinking glacier…

Investigating the potential for redox-active organic matter reduction in high elevation wetlands of the Colorado Rocky Mountains, USA
High elevation wetlands can support accelerated rates of biogeochemical cycling by storing and releasing large amounts of carbon (C). However, little is known about the controls on C cycling in these remote ecosystems. We investigated redox-active organic matter (RAOM) reduction, methane and carbon…

High Arctic vegetation lowers soil temperatures on sunny days despite low stature
The impact of vegetation on soil temperatures in low Arctic and boreal regions is well documented, where dense vegetation reduces soil temperatures. However, equivalent empirical evidence for influence of sparse, low-stature high Arctic vegetation and its interaction with cloud cover is limited…

Unraveling hydrologic and hydrochemical processes based on long-term concentration–discharge analysis in the Green Lake 4 catchment, Colorado Front Range, USA
Concentration–discharge (C-Q) relationships were analyzed over decadal, annual, and seasonal timescales from water years 1982 to 2020 to understand hydrologic and hydrochemical processes in the Green Lake 4 catchment, Green Lakes Valley, Colorado Front Range. Geogenic solutes, along with the…

Study on wind dynamics characteristics and sand transport laws in the Qinghai–Tibet Engineering Corridor
As the most important transportation corridor in the heart of the Qinghai–Tibet Plateau, the Qinghai–Tibet Engineering Corridor experiences varying degrees and forms of wind–sand hazards, posing serious threats to the construction and maintenance of infrastructure. To reveal the spatial…
