Solute sources and geochemical processes in Subglacial Lake Whillans, West Antarctica [PDF]
Geology, 2016 Subglacial Lake Whillans (SLW), West Antarctica, located beneath 800 m of ice is an active component of the subglacial hydrological network. The fill and drain behavior of SLW leads to long (years - decades) water residence times. Here, we present the aqueous geochemistry of the SLW water column and porewaters from a 36 cm sediment core.

Recognition of micro-scale deformation structures in glacial sediments - pattern perception, observer bias and the influence of experience [PDF]
, 2013 It is a scientist's mission to try to remain unbiased. However, certain factors play a role in scientific analyses that are not controlled by conscious thought.

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 ...

Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Geological and glacial-hydrologic controls on chemical weathering in the subglacial environment
Annals of Glaciology, 2022 A comparison of major ion chemistry of subglacial boreholes and discharging subglacial waters reveals three fundamentally different glacier hydrochemical regimes.

Reassessment of mid-Carboniferous glacial extent in southwestern Gondwana (Rio Blanco Basin, Argentina) inferred from paleo-mass transport of diamictites [PDF]
, 2013 Late Paleozoic glacial diamictites occur in many localities in western Argentina, indicating that the region was strongly affected by glaciation during the mid-Carboniferous (late Serpukhovian–early Bashkirian).

Antarctic Meltwater‐Stratification Feedback Is Less Pronounced Under High Climate Forcing
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Several studies have shown sub‐surface warming in the Southern Ocean via an increase in meltwater flux from the Antarctic Ice Sheet (AIS), which can lead to a positive feedback through enhanced basal melting. In this study, we investigate how the feedback strength is related to the prevailing climate in a coupled climate–ice‐sheet model.

Journal of Glaciology, 2018 Over recent decades, Greenland ice sheet surface melt has shown an increase both in intensity and spatial extent. Part of this water probably reaches the bed and can enhance glacier speed, advecting a larger volume of ice into the ablation area.

The sedimentary legacy of a palaeo-ice stream on the shelf of the southern Bellingshausen Sea: Clues to West Antarctic glacial history during the Late Quaternary [PDF]
, 2010 A major trough ("Belgica Trough") eroded by a palaeo-ice stream crosses the continental shelf of the southern Bellingshausen Sea (West Antarctica) and is associated with a trough mouth fan ("Belgica TMF") on the adjacent continental slope.
