Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

Decadal GPS-derived ice surface velocity along the transect from Zhongshan Station to and around Dome Argus, East Antarctica, 2005–16

Annals of Glaciology, 2018
Using repeat GPS measurements during 2005–16, we calculated and updated two-dimensional high-resolution decadal ice surface velocity estimates along the traverse route from Zhongshan Station to and around Dome Argus, East Antarctica.

Ice‐Sheet–Ocean Interactions and the Reversibility of a Regime Shift Beneath Filchner‐Ronne Ice Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Future atmospheric warming could cause an abrupt increase in ocean temperature beneath the Filchner–Ronne Ice Shelf, Antarctica, from −2.2°C to more than 0°C in a few decades. In simulations, such a transition leads to a twenty‐fold increase in sub‐shelf melt rates, driving a retreat of the ice sheet.

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

On the glaciological, meteorological, and climatological significance of Antarctic blue ice areas [PDF]

Reviews of Geophysics, 1999
This paper presents the current state of our knowledge about Antarctic blue ice areas. Scattered widely over the Antarctic continent yet covering only approximately 1% of its surface area, blue ice areas have some peculiar characteristics that make them of particular interest for planetary geologists, glaciologists, meteorologists, and climatologists ...

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

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.

Amplified Decline in Arctic Atmospheric Stability Under Arctic Warming

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Atmospheric stability quantifies the resistance of the atmosphere to vertical displacement and turbulent mixing. Under Arctic warming, the atmosphere has become more dynamically active, which may influence atmospheric stability. Using ERA5 reanalysis, we show that the decrease in Arctic atmospheric stability has been amplified relative to the ...
