Pathways and modification of warm water flowing beneath Thwaites Ice Shelf, West Antarctica

AK Wåhlin, AGC Graham, KA Hogan, BY Queste… - Science …, 2021 - science.org
Thwaites Glacier is the most rapidly changing outlet of the West Antarctic Ice Sheet and adds
large uncertainty to 21st century sea-level rise predictions. Here, we present the first direct …

An assessment of basal melt parameterisations for Antarctic ice shelves

C Burgard, NC Jourdain, R Reese, A Jenkins… - The …, 2022 - tc.copernicus.org

Repeated tidally induced hydrofracture of a supraglacial lake at the Amery Ice Shelf grounding zone

LD Trusel, Z Pan, M Moussavi - Geophysical Research Letters, 2022 - Wiley Online Library
Surface melting and lakes are common to Antarctic ice shelves, and their existence and
drainages have been invoked as a precursor for ice shelf collapse. Here, we present …

Ice shelf basal melt sensitivity to tide‐induced mixing based on the theory of subglacial plumes

J Anselin, BC Reed, A Jenkins… - Journal of Geophysical …, 2023 - Wiley Online Library
Tidal currents are known to influence basal melting of Antarctic ice shelves through two
types of mechanisms: local processes taking place within the boundary current adjacent to …

RB Latto, RJ Turner, AM Reading, S Cook… - The …, 2024 - tc.copernicus.org
Given the high number and diversity of events in a typical cryoseismic dataset, in particular
those recorded on ice sheet margins, it is desirable to use a semi-automated method of …

Towards the systematic reconnaissance of seismic signals from glaciers and ice sheets–Part 1: Event detection for cryoseismology

RB Latto, RJ Turner, AM Reading, JP Winberry - The Cryosphere, 2024 - tc.copernicus.org
Cryoseismology is a powerful toolset for progressing the understanding of the structure and
