Contrasting melt regime in the Ice Grounding Zone of Thwaites Glacier, West Antarctica. [PDF]

Proc Natl Acad Sci U S A
Significance The transition boundary between continental and floating ice, or grounding line, is traditionally represented as a fixed boundary experiencing zero ice melt.

Damage intensity increases ice mass loss from Thwaites Glacier, Antarctica [PDF]

The Cryosphere
Ice damage, which results from the formation and development of crevasses on glaciers, plays a critical role in ice-shelf stability, grounding-line retreat, and subsequent sea-level rise. Yet, few ice-sheet models explicitly account for ice damage or its

Recent benthic foraminifera communities offshore of Thwaites Glacier in the Amundsen Sea, Antarctica: implications for interpretations of fossil assemblages [PDF]

Journal of Micropalaeontology
Benthic foraminiferal assemblages are useful tools for paleoenvironmental studies but rely on the calibration of live populations to modern environmental conditions to allow interpretation of this proxy downcore. In regions such as the region offshore of

Calving Dynamics and the Potential Impact of Mélange Buttressing at the Western Calving Front of Thwaites Glacier, West Antarctica [PDF]

Journal of Geophysical Research - Earth Surface
The western region of the wide Thwaites Glacier terminus is characterized by a near‐vertical calving front. The grounding line at this western calving front (WCF) rests on a relatively high ridge, behind which exists a reverse‐sloping bed; retreat of the

Model insights into bed control on retreat of Thwaites Glacier, West Antarctica

Journal of Glaciology, 2023
Thwaites Glacier (TG) plays an important role in future sea-level rise (SLR) contribution from the West Antarctic Ice Sheet. Recent observations show that TG is losing mass, and its grounding zone is retreating.

Velocity map of the Thwaites Glacier catchment, West Antarctica [PDF]

Journal of Glaciology, 2004
AbstractThe two-dimensional surface velocity of Thwaites Glacier, West Antarctica, was mapped with 23 ascending- and 22 descending-orbit European Remote-sensing Satellite synthetic aperture radar (ERS SAR) interferograms (time range 1995–2000). The velocity map covers 175 500 km2 from the Amundsen Coast to the southern turning point of the satellite ...

Rift-Related Sedimentary Basin and Deeper-Seated Mafic Intrusions Modeled Beneath Thwaites Glacier, West Antarctica: Influence on Glacier Dynamics

Journal of Geophysical Research: Solid Earth
Thwaites Glacier in West Antarctica has been identified as a route to destabilization of the whole West Antarctic Ice Sheet, potentially leading to several meters of sea‐level rise. However, future evolution of Thwaites Glacier remains uncertain due to a

Large-Scale Atmospheric Drivers of Snowfall Over Thwaites Glacier, Antarctica

Geophysical Research Letters, 2021
High snowfall events on Thwaites Glacier (TG, West Antarctica) are a key influencer of its mass balance, and can act to mitigate sea level rise due to ocean warming‐induced ice loss.

Unsteady flow inferred for Thwaites Glacier, and comparison with Pine Island Glacier, West Antarctica [PDF]

Journal of Glaciology, 2002
AbstractWe present a comparison of surface velocities in 1996, derived from interferometric synthetic aperture radar, with an estimate of the long-term, depth-averaged velocity based on the assumption of steady-state flow for both Pine Island Glacier and its neighbour, Thwaites Glacier, West Antarctica.

GHOSTly flute music: drumlins, moats and the bed of Thwaites Glacier

Annals of Glaciology, 2022
Glacier-bed characteristics that are poorly known and modeled are important in projected sea-level rise from ice-sheet changes under strong warming, especially in the Thwaites Glacier drainage of West Antarctica.
