Glaciological and Chemical Characteristics of an Antarctic Inland Plateau (Abstract) [PDF]

Annals of Glaciology, 1988
A glaciological research project in east Queen Maud Land, Antarctica, has been carried out by the Japanese Antarctic Research Expeditions between 1982 and 1986 (JARE-23 – JARE-27).In this paper, we deal with the area traversed by JARE-25 and JARE-26, a representative inland plateau in Antarctica.

Increased Glacier Melt Across Millennia to Hours Enhances Erosion and Sediment Export Processes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract Glacial erosion and sediment evacuation are key in shaping polar and mountain landscapes and influencing downstream ecological and social systems. The glacier dynamics and hydrology responsible for these processes are closely linked to hydrological and climatic (hydro‐climatic) conditions.

A 700 year record of Southern Hemisphere extratropical climate variability [PDF]

, 2004
Annually dated ice cores from West and East Antarctica provide proxies for past changes in atmospheric circulation over Antarctica and portions of the Southern Ocean, temperature in coastal West and East Antarctica, and the frequency of South Polar ...

Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

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,

Unexpectedly High Accumulation Rates in the 2022 Mt. Logan Ice Core Reveal Warm‐Season Drivers of Precipitation Variability

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Ice cores from Mt. Logan, the second highest peak in North America located in the St. Elias mountains in southwest Yukon, Canada, have provided conflicting accumulation records, thus the hydroclimate response to changing atmospheric conditions in the highest elevation regions is not well constrained.

A Hierarchical Spatio-Temporal Statistical Model Motivated by Glaciology [PDF]

, 2019
In this paper, we extend and analyze a Bayesian hierarchical spatio-temporal model for physical systems. A novelty is to model the discrepancy between the output of a computer simulator for a physical process and the actual process values with a ...

Future Atmospheric Rivers in Antarctica: Characteristics and Impacts With the IPSL Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Atmospheric rivers (ARs) are narrow corridors of intense water vapor transport that have significant impacts on the Antarctic surface mass balance (SMB) through both snow accumulation and surface melt due to rain and heat. To estimate their impacts on future SMB, we study Antarctic ARs in an ensemble of 21st‐century simulations of the IPSL‐CM6

The Antarctic Subglacial Lake Vostok: Glaciology, Biology and Planetology [PDF]

Eos, Transactions American Geophysical Union, 2006
Igor Zotikov has been involved in Antarctic glaciological research since the 1957–1958 third International Polar Year (IPY). His theoretical analyses of ice flow and heat transfer were important early contributions to our present understanding of the Antarctic Ice Sheet.

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]

, 2017
A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by
