Seismo‐Acoustic Detection and Localization of Iceberg Collapse in Atka Bay, Antarctica

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract On 12 January 2022, an iceberg collapsed at the edge of frozen Atka Bay, Antarctica. The event generated seismic, hydroacoustic, and atmospheric infrasound waves recorded by a local network comprising land‐ and iceshelf‐based seismometers, an underwater hydrophone, and an on‐ice infrasound array.

Rapid submarine ice melting in the grounding zones of ice shelves in West Antarctica. [PDF]

, 2016
Enhanced submarine ice-shelf melting strongly controls ice loss in the Amundsen Sea embayment (ASE) of West Antarctica, but its magnitude is not well known in the critical grounding zones of the ASE's major glaciers.

Vulnerability assessment and analysis of cryosphere changes in the Western Sichuan Plateau

Arctic, Antarctic, and Alpine Research
A vulnerability assessment model and indicator system for the changes in the cryosphere in the Western Sichuan Plateau are constructed based on the “exposure–sensitivity–adaptive capacity” framework. The model aims to capture the multiple characteristics

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 ...

Influence of Cloud Microphysical Properties on Airborne Lidar Measurements: Results From the IMPACTS Field Campaign

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract Ice‐ and mixed‐phase clouds play an important role in the global radiative budget and hydrological cycle, yet the complexity of ice crystal shapes and the presence of supercooled liquid water (SCLW) present challenges for retrieving cloud properties from airborne and spaceborne remote sensing instruments.

Representing moisture fluxes and phase changes in glacier debris cover using a reservoir approach [PDF]

, 2014
Due to the complexity of treating moisture in supraglacial debris, surface energy balance models to date have neglected moisture infiltration and phase changes in the debris layer.

GROWTH OF GAS HYDRATES IN THE WATER/OIL EMULSIONS ACCORDING TO METHOD DIFFERENTIAL THERMAL ANALYSIS

Известия высших учебных заведений: Нефть и газ, 2014
Some experimental aspects of the DTA method for determination of a degree of hydrate formation of water/oil emulsion samples are considered. The growth of hydrate in micron-size droplets of water depending on a number of cycles of freezing – thawing is ...

The Hickory Run Boulder Field, Carbon County, Pennsylvania, USA: Morphology, sedimentology and development

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Relative weathering indices and three‐dimensional fabric analyses demonstrate allochthonous emplacement of the Hickory Run Boulder Field via periglacial mass movement. Spatially coherent trends confirm a time‐transgressive surface formed under Pleistocene permafrost conditions, with tributary‐like integration of clasts from a secondary boulder field ...

Savor the Cryosphere

GSA Today, 2017
This article provides concise documentation of the ongoing retreat of glaciers, along with the implications that the ice loss presents, as well as suggestions for geoscience educators to better convey this story to both students and citizens. We present the retreat of glaciers—the loss of ice—as emblematic of the recent, rapid contraction of the ...

Hydro‐Climatic Modelling for Water Resources: From Processes to Adaptive Management and Governance

Hydrological Processes, Volume 39, Issue 12, December 2025.
This study explores hydro‐climatic modelling through theoretical analysis, experimental investigations and advanced simulations (DNS, LES, CFD). By examining multi‐scale dynamics, microphysical processes and biogeochemical cycles (water, carbon, nitrogen), it analyses feedback complexities and cross‐scale interactions.
