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

The Cryosphere, 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.

Reduced West Antarctic Ice Sheet Size During Prominent Quaternary Interglacials Constrained by Iceberg‐Rafted Debris Provenance in the Amundsen Sea

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The stability of the West Antarctic Ice Sheet (WAIS) remains a major uncertainty in sea‐level projections, and geologic records provide important constraints on its past behavior. We present 40Ar/39Ar ages of biotite and hornblende grains from iceberg‐rafted debris (IRD) in two Amundsen Sea sediment cores (PC493 and PS58/254), located south ...

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

Mapping Debris-Covered Glaciers Using High-Resolution Imagery (GF-2) and Deep Learning Algorithms

Remote Sensing
Glacier inventories are fundamental in understanding glacier dynamics and glacier-related environmental processes. High-resolution mapping of glacier outlines is lacking, although high-resolution satellite images have become available in recent decades ...

Alaska‐Yukon Glacier Depths From a Decade of Airborne Radar Sounding

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract NASA's Operation IceBridge employed airborne radar sounders in Alaska and adjacent northwestern Canada between 2012 and 2021 to measure the thickness of the region's glaciers. Here we present the first comprehensive analysis of these data, analyzing ∼31,700 linear‐km of radar profile data to provide over 5,500 linear‐km of ice thickness and ...

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).

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Pond Dynamics and Supraglacial-Englacial Connectivity on Debris-Covered Lirung Glacier, Nepal

Frontiers in Earth Science, 2017
The hydrological systems of heavily-downwasted debris-covered glaciers differ from those of clean-ice glaciers due to the hummocky surface and debris mantle of such glaciers, leading to a relatively limited understanding of drainage pathways ...

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, Volume 62, Issue 3, Page 818-845, June 2026.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

Boreas
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is
