Vibroseismic measurements on Thwaites Glacier, Antarctica from 2022/23

This vibroseismic survey was conducted on Thwaites Glacier in West Antarctica in 2022/23, as part of the International Thwaites Glacier Collaboration's project GHOST (Geophysical Habitat of Subglacial Thwaites).

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]

, 2012
Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

High Fraction of Glacial Meltwater Along Two Separate Isopycnals Observed in Summer 2020 Near and Off the Pine Island and Thwaites Ice Shelves, West Antarctica

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The spatial distribution and dynamics of glacial meltwater (MW) influence ocean circulation off and basal melt rate below Antarctic ice shelves. While previous studies described the MW distribution in Pine Island Bay off Pine Island Ice Shelf (PIIS), quantitative constraints on the spatial heterogeneity of the spread of MW associated with ...

Grounding‐Zone Wedge Formation and Effects on Ice‐Stream Retreat and Stability

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Ice streams deposit sediment at their grounding lines, where ice reaches flotation. Grounding Zone Wedge (GZW) deposits indicate stillstands in past grounding‐line retreat, and are thought to stabilize grounding lines by reducing local water depth, restricting ice flow. However, the mechanisms of GZW growth are uncertain, as are the effects of

Seashells and Penguin Bones Reveal Thwaites Glacier’s Quiet Past

Eos, 2022
Antarctica’s Thwaites and Pine Island Glaciers are melting faster than they have in the past 5,500 years, new evidence shows. Against expectations, their pasts have been remarkably stable.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, Volume 55, Issue 2, Page 476-502, April 2026.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Lateral Fluxes Drive Basal Melting Beneath Thwaites Eastern Ice Shelf, West Antarctica

Geophysical Research Letters
Thwaites Glacier is one of the fastest‐changing ice‐ocean systems in Antarctica. Basal melting beneath Thwaites' floating ice shelf, especially around pinning points and at the grounding line, sets the rate of ice loss and Thwaites' contribution to ...

Direct Geologic Constraints on the Timing of Late Holocene Ice Thickening in the Amundsen Sea Embayment, Antarctica

Geophysical Research Letters
Constraining past West Antarctic Ice Sheet (WAIS) change helps validate numerical models simulating future ice sheet dynamics. Following rapid deglaciation during the mid‐Holocene, ice near Thwaites Glacier was ∼35 m thinner than present; however, the ...

Model Setup of Thwaites Glacier

, 2018
We set up our Thwaites model to study its evolution in the next 100 years. We use BEDMAP-2 data for ice surface elevation and ice shelf draft elevation (Fretwell et al., 2013).
