Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Englacial drainage structures in an East Antarctic outlet glacier
Journal of Glaciology, 2020 Ground-penetrating radar data acquired in the 2016/17 austral summer on Sørsdal Glacier, East Antarctica, provide evidence for meltwater lenses within porous surface ice that are conceptually similar to firn aquifers observed on the Greenland Ice Sheet ...

Radio-echo soundings on Icelandic temperate glaciers: history of techniques and findings
Annals of Glaciology, 2020 Since the mid-1970s radio-echo soundings have been conducted on Iceland's temperate glaciers. Since then, low-frequency radar technology has furthered the study of most of the island's ice caps.

Analysis of ice-sheet temperature profiles from low-frequency airborne remote sensing
Journal of Glaciology, 2022 Ice internal temperature and basal geothermal heat flux (GHF) are analyzed along a study line in northwestern Greenland. The temperatures were obtained from a previously reported inversion of airborne microwave brightness-temperature spectra.

Soils of western Wright Valley, Antarctica [PDF]
, 2009 Western Wright Valley, from Wright Upper Glacier to the western end of the Dais, can be divided into three broad geomorphic regions: the elevated Labyrinth, the narrow Dais which is connected to the Labyrinth, and the North and South forks which are ...

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]
, 2008 Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Using active geophysical methods to characterise a temperate glacier’s hydrological system
, 2021 Worldwide, glaciers are receding as a consequence of climate change. Due to the global glacier recession, glaciers are experiencing enhanced melting, which results in an increase in meltwater availability. This increased meltwater has the ability to alter the glacier's hydraulic conditions and ultimately affects the dynamics of glaciers.
