Life hung by a thread: endurance of Antarctic fauna in glacial periods [PDF]

, 2008
Today, Antarctica exhibits some of the harshest environmental conditions for life on Earth. During the last glacial period, Antarctic terrestrial and marine life was challenged by even more extreme environmental conditions.

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.

The Overprint of Transient Rheology on Laterally Heterogeneous Viscosity: Influences on Sea‐Level Change Driven by Antarctic Ice Sheet Loss

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Through bedrock deformation, solid Earth dynamics (specifically, glacial isostatic adjustment or GIA) influences ice sheet mass balance, especially for marine‐based ice sheets like the West Antarctic ice sheet (WAIS). As ice sheets retreat, crustal uplift can help stabilize a marine based ice sheet by reducing the ice exposed at the grounding ...

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.

Glacial Imprints and Marine Overprints: Sediment Architecture and Fjord Evolution in Fiordland, New Zealand

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Fjords are globally significant sedimentary archives that record the relationship between glacial, tectonic, and marine processes. Fiordland, on the southwest coast of New Zealand, hosts one of the most extensive temperate fjord provinces in the Southern Hemisphere, yet its postglacial evolution has remained poorly constrained.

Synchronous terminus change of East Antarctic outlet glaciers linked to climatic forcing [PDF]

, 2013
In recent years there has been a growing trend of acceleration, thinning and retreat of ocean-terminating outlet glaciers in both the Greenland and West Antarctic Ice Sheets, resulting in an increasing contribution to sea level rise.

Increased Frequency, Duration, and Area of Winter Polynyas North of Greenland in a Warming Climate

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Polynyas play a crucial role in the polar marine ecosystems and climate system. Four winter polynya events north of Greenland have been observed, but the response of winter polynyas to climate warming remains unknown. This study investigates projected changes in winter polynyas in the Wandel Sea north of Greenland using the AWI‐CM3 climate ...

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

Increasing Winter Storminess in the Southern Ross Sea, Antarctica, and Its Impact on Land‐Fast Sea‐Ice

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In the Ross Sea, sea‐ice processes such as coastal polynya formation and fast‐ice breakouts are often driven by strong winds associated with storms. In this study, a storm index derived from air pressure and air temperature anomalies observed at 13 weather stations in the Ross Sea region was used to investigate storm behavior between 1964 and ...
