Impacts of Temperature‐ and Stress‐Dependent Rheology on Ice‐Shelf‐Front Bending

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Classical treatments of ice‐shelf bending suggest that shelf fronts should bend downwards, due to the distribution of hydrostatic water pressure at the front. However, LiDAR data show several instances of upward‐bending ice‐shelf fronts. While this phenomenon has often been attributed to a buoyant force from a submerged ice bench, recent work ...

Ice loss processes in the Seal Nunataks ice shelf region from satellite altimetry and imagery

Annals of Glaciology, 2016
The Seal Nunataks ice shelf (SNIS, ~743 km2 in 2013) is an unofficial name for a remnant area between the former Larsen A and Larsen B ice shelves off the northeastern Antarctic Peninsula. Analyses using Landsat 7 ETM+ and Terra ASTER images from 2001 to

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.

Characteristics of Cherenkov Radiation in Naturally Occuring Ice

, 2016
We revisit the theory of Cherenkov radiation in uniaxial crystals. Historically, a number of flawed attempts have been made at explaining this radiation phenomenon and a consistent error-free description is nowhere available.

Palaeoglacier reconstruction and dynamics of Cordillera Vilcanota in the tropical high Peruvian Andes

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

Silicate and Carbonate Weathering Perturbation at the Eocene‐Oligocene Transition Recorded by Mg Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...

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.

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...
