Cosmogenic ²¹Ne exposure ages on late Pleistocene moraines in Lassen Volcanic National Park, California, USA [PDF]

Geochronology
We report new cosmogenic 21Ne in quartz exposure ages from 18 samples on three distinct moraines deposited in the Lost Creek drainage, approximately 3–7 km down-valley from Lassen Peak in Lassen Volcanic National Park.

Physicochemical Impacts of Dust Storms on Aerosol and Glacier Meltwater on the Northern Margin of the Taklimakan Desert

Frontiers in Earth Science, 2021
To analyze the impacts of dust storms on the atmospheric and meltwater environment, intensive and simultaneous sampling for aerosols and meltwater on the terminal moraine (41°73′ N, 79°88′ E, 3,789 m a.s.l.) of Qingbingtan Glacier No. 72 (Glacier No. 72)

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

Boreas, EarlyView.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

New age constraints reveal moraine stabilization thousands of years after deposition during the last deglaciation of western New York, USA [PDF]

Geochronology
The timing of the last deglaciation of the Laurentide Ice Sheet in western New York is poorly constrained. The lack of direct chronology in the region has led to a hypothesis that the Laurentide Ice Sheet re-advanced to near its Last Glacial Maximum ...

Structure and evolution of the drainage system of a Himalayan debris-covered glacier, and its relationship with patterns of mass loss [PDF]

The Cryosphere, 2017
We provide the first synoptic view of the drainage system of a Himalayan debris-covered glacier and its evolution through time, based on speleological exploration and satellite image analysis of Ngozumpa Glacier, Nepal. The drainage system has several

Rapid mass movements triggered by an atmospheric river in Disko Island, West Greenland

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
In early July 2023, a series of rapid mass movements was triggered by extreme precipitation carried by an atmospheric river in Disko Island, West Greenland. During 18 h total precipitation reached up to 115 mm, causing more than 150 slushflows in different areas of the island and substantial damage to some infrastructure close to the Qeqertarsuaq ...

Ecological and Genetic Insights Into Antarctic Fairy Shrimp, Branchinecta gaini Daday, 1910 (Branchiopoda: Anostraca) Populations on King George Island, Antarctica

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT The Antarctic fairy shrimp (Branchinecta gaini) is the largest inland animal in Antarctica and a key component of its freshwater ecosystems. Despite its broad distribution, little is known about its population structure, habitat tolerance, and potential vulnerability to climate change. This study investigated the occurrence, genetic structure,

Progressive Development of a Paraglacial Rock Slope Failure at Portage Glacier, Alaska

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 11, November 2025.
Abstract Paraglacial landscapes are rapidly transforming as thinning and retreating glaciers expose adjacent slopes to new conditions. In Southcentral Alaska, a large slope instability at Portage Glacier has been deforming progressively up‐glacier over the past six decades.

The effect of weather and landscape conditions on productivity of the spring wheat variety ‘Zlata’

Зерновое хозяйство России, 2023
The current study was carried out in 2010–2022 to determine the effect of weather and landscape conditions on productivity of spring wheat (Triticumaestivum) in a stationary field trial located on a drained soddy-podzolic soil within a terminal moraine ...
