Pathways and modification of warm water flowing beneath Thwaites Ice Shelf, West Antarctica
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
Ocean-induced ice-shelf melt is one of the largest uncertainty factors in the Antarctic
contribution to future sea-level rise. Several parameterisations exist, linking oceanic …

Crevasse refreezing and signatures of retreat observed at Kamb Ice Stream grounding zone
Ice streams flowing into Ross Ice Shelf are presently responsible for around 10% of the
mass flux from West Antarctica, with the noteworthy exception of Kamb Ice Stream, which …

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
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 …

Towards the systematic reconnaissance of seismic signals from glaciers and ice sheets–Part 2: Unsupervised learning for source process characterization
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
Cryoseismology is a powerful toolset for progressing the understanding of the structure and
dynamics of glaciers and ice sheets. It can enable the detection of hidden processes such as …

Observing glacier dynamics with low-cost, multi-GNSS positioning in Victoria Land, Antarctica
This study examines the performance of low-cost, low-power GNSS positioning systems for
glacier monitoring in high-latitude environments. We compare the positioning performance …

Observed tidal currents in Prydz Bay and their contribution to the Amery Ice Shelf basal melting
Tides play a key role in regulating the circulation and water properties around Antarctica, yet
tidal currents and the corresponding influences in Prydz Bay have not been quantified with …
