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.

The Grounding of an Ice Shelf in the Central Arctic Ocean: A Modeling Experiment [PDF]

, 2003
A numerical ice sheet model was used in a first test towards evaluating the hypothesis that, during a period of large-scale glaciation, an ice shelf emanating from the Barents/Kara Seas grounded across parts of the Lomonosov Ridge to a depth of around ...

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 ...

Drivers of the 2018 Winter Temperature Anomaly Over East Antarctica: Dominant Role of Air‐Sea‐Ice Dynamical‐Thermodynamic Coupling

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract During the 2018 Southern Hemisphere winter, a pronounced surface air temperature positive anomaly occurred over East Antarctica, with Zhongshan Station recording its highest winter‐mean air temperature since 2007. Combining in situ observations, satellite remote sensing, and reanalysis data sets, this study diagnoses the temperature anomalies ...

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Influence of Glaciological Structures on the Spatial Distribution of Cryoconite Holes, Northern Victoria Land, East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Three blue‐ice areas in the upper reaches of Rennick Glacier, East Antarctica, are investigated using satellite remote sensing to assess the influence of meso‐ to large‐scale glaciological structures on cryoconite hole distributions. In total, 15,299 cryoconite holes and 1 600 structures were geospatially analyzed, which indicate that ...

A comparison of automated approaches to extracting englacial-layer geometry from radar data across ice sheets

Annals of Glaciology, 2020
Radar surveys across ice sheets typically measure numerous englacial layers that can often be regarded as isochrones. Such layers are valuable for extrapolating age–depth relationships away from ice-core locations, reconstructing palaeoaccumulation ...

Subglacial Conditions From Converted‐Wave Seismic Reflection Amplitudes: Synthetic Experiments and Case Study Reveal a Frozen Bed at an Antarctic Ice Rise

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Estimating the seismic reflectivity of the glacial ice‐bed interface is a powerful means to quantify subglacial properties, which is important for parameterizing sliding laws in ice sheet models and understanding ice sheet history. Amplitude‐versus‐angle (AVA) analysis measures reflectivity with incidence angle and is sensitive to the ...

Surface velocity fluctuations for Glaciar Universidad, central Chile, between 1967 and 2015

Journal of Glaciology, 2016
For the Andes Cordillera, where observed mass-balance records are sparse, long-term glacier velocity measurements potentially represent a useful tool for assessing glacier health.
