Alpine glacier algal bloom during a record melt year

Frontiers in Microbiology
Glacier algal blooms dominate the surfaces of glaciers and ice sheets during summer melt seasons, with larger blooms anticipated in years that experience the greatest melt.

Does Polar Warming Asymmetry Exist in Bathy‐Planet Experiments?

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Ocean bathymetry and continental geometry shape ocean circulation, but whether these geographic constraints can sustain polar warming asymmetry in a fully coupled climate system remains unclear. Here we construct a fully coupled “bathy‐planet” configuration (BATHY), in which continental topography is removed and most land surfaces are replaced

Mechanical analysis of pinning points in the Ross Ice Shelf, Antarctica

Annals of Glaciology, 2019
Ice shelves regulate the rate of ice-sheet discharge along much of the Antarctic coastline. Pinning points, sites of localised grounding within floating ice, can in turn, regulate the flow and thickness of an ice shelf.

Permafrost Degradation Drives Shifts in Chemostasis and Stream Geochemistry in the McMurdo Dry Valleys, Antarctica

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract In the McMurdo Dry Valleys, Antarctica's largest ice‐free area, the stream channels consist of rock and sediment that are underlain by permafrost. Substantial permafrost degradation and channel erosion occurred in January 2012 on the west branch of Crescent Stream, while the east branch remained unaffected.

The potential of marine ice cliff instability for Amundsen Sea glaciers revisited

Annals of Glaciology
Marine ice cliff instability (MICI) is the hypothesis that self-sustained retreat of ice sheets can be initiated when sufficiently tall ice cliffs are exposed.

Evaluation of Riming in the P3‐2ice Microphysics Scheme: A Case Study of Cold‐Air Outbreak Snowfall in Eastern China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Using the multi‐frequency radar suite, ground‐based observations, and the Weather Research and Forecasting (WRF) model with the Predicted Particle Properties microphysics scheme with the version of two‐ice category (P3‐2ice), we study the characteristics of a cold‐air outbreak (CAO) snowfall event on 6–7 December 2024.

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 Cryosphere
Ice 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.

Recent trends in melting conditions on the Antarctic Peninsula and their implications for ice-sheet mass balance and sea level [PDF]

, 2006
Long-term records from meteorological stations on the Antarctic Peninsula show strong rising trends in the annual duration of melting conditions. In each case, the trend is statistically significant and represents a major increase in the potential for ...

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.
