Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Projections of Antarctica's sea‐level contribution depend on future changes in surface mass balance (SMB), yet it remains uncertain whether climate change has already impacted SMB on the East Antarctic Plateau, given diverging trends in prior studies.

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,

Quantifying Under‐Ice Phytoplankton Blooms in the Changing Arctic and Southern Oceans
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Historically, polar marine phytoplankton were thought to primarily grow after the seasonal breakup of sea ice, when there is plentiful light available in the surface ocean. However, observations of substantial productivity under sea ice has called this assumption into question.

The potential of marine ice cliff instability for Amundsen Sea glaciers revisited
Annals of GlaciologyMarine ice cliff instability (MICI) is the hypothesis that self-sustained retreat of ice sheets can be initiated when sufficiently tall ice cliffs are exposed.

Near Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...

Professor F. Alton Wade’s Antarctic Glaciological Researches [PDF]
Journal of Glaciology, 1947 On 7 May 1939 Professor F. Alton Wade, Chief Geologist of Admiral Byrd’s Third Antarctic Expedition, which came to be known as the U.S. Antarctic Service Expedition 1939–41, wrote a letter in the course of which he expressed the view that the efforts of the various expeditions to the polar regions should be more closely coordinated than they had been ...

The spatial glaciological data infrastructure
Лëд и снег, 2015 Substantial and rapid environmental changes require developing methods which could be able to manage huge information flows, to optimize processes of the data acquisition, storage, analysis, and exchange.

Reproductive success in Antarctic marine invertebrates [PDF]
, 2005 The nearshore Antarctic marine environment is unique, characterised by low but constant temperatures that contrast with an intense peak in productivity. As a result of this stenothermal environment, energy input has a profound ecological effect.

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.

Brief communication: Reduced bandwidth improves the depth limit of the radar coherence method for detecting ice crystal fabric asymmetry [PDF]
The CryosphereIce crystal orientation fabric strongly affects the viscous deformation of glacier ice. A popular technique to investigate ice fabric is radar polarimetry, often analysed using the coherence method.
