Bathymetry and bed conditions of Lago Subglacial CECs, West Antarctica

Journal of Glaciology, 2023
Although over 600 Antarctic subglacial lakes have been identified using radar and satellite observations, the bathymetry and bed properties, which are key to understanding conditions within the lake, have been determined in very few localities.

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 725-752, October/December 2026.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Spatial–temporal dynamics of chemical composition of surface snow in East Antarctica along the Progress station–Vostok station transect [PDF]

The Cryosphere, 2014
In January of 2008, during the 53rd Russian Antarctic Expedition, surface snow samples were taken from 13 shallow (0.7 to 1.5 m depth) snow pits along the first tractor traverse from Progress to Vostok stations, East Antarctica.

Returning Climate to Present Day May not Reduce Antarctic Mass Loss

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Using the BISICLES ice sheet model, we explore the Antarctic Ice Sheet's response over the 22nd century under two climate scenarios. In the return scenario, climate forcing is returned to present‐day levels (2015) in either 2050 or 2100 and then held constant until 2200.

Alaskan Glaciers in a Warming Climate

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Glaciers across Alaska are undergoing rapid mass loss, with implications for sea‐level rise, natural hazards, water resources, and more. Here, we utilize new snowline and melt extent observations of Alaskan glaciers at high spatiotemporal resolutions to improve projections to 2100.

Scalable Phase‐Field Implementation of Crack Evolution (SPICE) for Modeling Surface Crevasse Growth and Interaction in Glaciers

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Iceberg calving driven by crevasse propagation is an important source of ice loss from the Greenland and Antarctic ice sheets. However, simulating crevasse growth and interaction in 3D, spanning meters to kilometers length scales, remains computationally challenging for high‐fidelity models based on nonlocal continuum damage mechanics and ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, Volume 55, Issue 4, Page 1073-1101, October 2026.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Five decades of strong temporal variability in the flow of Brunt Ice Shelf, Antarctica

Journal of Glaciology, 2017
Data showing velocity changes on the Brunt Ice Shelf (BIS), Antarctica, over the last 55 years are presented and analysed. During this period no large-scale calving events took place and the ice shelf gradually grew in size. Ice flow velocities, however,

Thermodynamic Control of Global Seasonal Snow Decline

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Seasonal snowfall is declining globally, yet the relative roles of precipitation variability versus warming‐induced phase transitions remain poorly quantified. We develop a physically based attribution framework that decomposes snowfall trends (1983–2023) into hydrological (precipitation‐driven) and thermodynamic (phase‐driven) components ...

Glacier‐Climate Feedbacks Modulate Last Glacial Maximum Dust Cycle Over the Third Pole

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Geological records indicate only a modest Last Glacial Maximum (LGM) increase in dust deposition over the Third Pole (TP), in contrast to the order‐of‐magnitude rise at high latitudes. Existing climate simulations, which generally prescribe present‐day or no TP glaciers, have struggled to reproduce this muted response.
