The Impact of Basal Roughness on Inland Thwaites Glacier Sliding [PDF]

Geophysical Research Letters, 2022
Swath radar technology enables three‐dimensional mapping of modern glacier beds over large areas at resolutions that are higher than those typically used in ice‐flow models.

Heterogeneous melting near the Thwaites Glacier grounding line. [PDF]

Nature, 2023
Thwaites Eastern Ice Shelf observations from a new underwater vehicle show that high melt rates occur where ice is sharply sloped at the ocean interface, with lower melt where the ice is comparatively flat.

Rapid retreat of Thwaites Glacier in the pre-satellite era. [PDF]

Nat Geosci, 2022
Understanding the recent history of Thwaites Glacier, and the processes controlling its ongoing retreat, is key to projecting Antarctic contributions to future sea-level rise.

Suppressed basal melting in the eastern Thwaites Glacier grounding zone. [PDF]

Nature, 2023
Despite observations from a hot-water-drilled access hole showing warm ocean waters beneath Thwaites Glacier Eastern Ice Shelf, the basal melt rate is strongly suppressed due to the low current speeds and strong density stratification.

Strong Ocean Melting Feedback During the Recent Retreat of Thwaites Glacier [PDF]

Geophysical Research Letters, 2023
Accelerating ice loss from Thwaites Glacier is contributing approximately 5% of global sea‐level rise, and could add tens of centimeters to sea level over the coming centuries.

Hard rocks and deep wetlands beneath Thwaites Glacier in Antarctica [PDF]

Communications Earth & Environment
Thwaites Glacier in West Antarctica is losing ice rapidly and is considered especially vulnerable to retreat, but predictions of its future remain limited by uncertainties about its subglacial properties.

Drivers of Change of Thwaites Glacier, West Antarctica, Between 1995 and 2015 [PDF]

Geophysical Research Letters, 2021
Using three independent ice‐flow models and several satellite‐based datasets, we assess the importance of correctly capturing ice‐shelf breakup, shelf thinning, and reduction in basal traction from ungrounding in reproducing observed speed‐up and ...

The influence of subglacial lake discharge on Thwaites Glacier ice-shelf melting and grounding-line retreat [PDF]

Nature Communications
The retreat of the Antarctic Ice Sheet is conventionally attributed to increased ocean melting of ice shelves, potentially enhanced by internal instability from grounding lines near retrograde bed slopes.

Sea-level contribution from Thwaites Glacier doubles in an observation-constrained ice-sheet model [PDF]

Nature Communications
Thwaites Glacier is a major contributor to Antarctic mass loss and a key source of uncertainty in future sea-level rise. Ocean-driven melting at its grounding line drives rapid retreat, yet most models treat the transition between grounded and floating ...

Analysis of continuous calving front retreat and the associated influencing factors of the Thwaites Glacier using high-resolution remote sensing data from 2015 to 2023

International Journal of Digital Earth
The Thwaites Glacier (TG), accounting for four percent of present-day sea-level rise, has been confirmed with the irreversible retreat and thinning. Consequently, understanding the continuous calving front retreat within the TG is pivotal for accurately ...
