Bedforms of Thwaites Glacier, West Antarctica: Character and Origin [PDF]
Journal of Geophysical Research F: Earth Surface, 2021 Bedforms of Thwaites Glacier, West Antarctica both record and affect ice flow, as shown by geophysical data and simple models. Thwaites Glacier flows across the tectonic fabric of the West Antarctic rift system with its bedrock highs and sedimentary ...

Brief communication: Thwaites Glacier cavity evolution [PDF]
The Cryosphere, 2021 Between 2014 and 2017, ocean melt eroded a large cavity beneath and along the western margin of the fast-flowing core of Thwaites Glacier. Here we show that from 2017 to the end of 2020 the cavity persisted but did not expand.

Heterogeneous retreat and ice melt of Thwaites Glacier, West Antarctica. [PDF]
Sci Adv, 2019 The heterogeneous retreat of Thwaites glacier indicates complexities of ice melt processes taking place at the grounding zone. The glaciers flowing into the Amundsen Sea Embayment, West Antarctica, have undergone acceleration and grounding line retreat ...

Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, Antarctica [PDF]
Frontiers in Earth Science, 2022 Subglacial meltwater drainage can enhance localized melting along grounding zones and beneath the ice shelves of marine-terminating glaciers. Efforts to constrain the evolution of subglacial hydrology and the resulting influence on ice stability in space

Weakening of the pinning point buttressing Thwaites Glacier, West Antarctica [PDF]
The Cryosphere, 2022 The Thwaites Eastern Ice Shelf buttresses a significant portion of Thwaites Glacier through contact with a pinning point 40 km offshore of the present grounding line. Predicting future rates of Thwaites Glacier’s contribution to sea-level rise depends on

Mass Loss From Thwaites Glacier Continues Even Without Ocean Melting
Geophysical Research LettersPine Island and Thwaites glaciers dominate Antarctica's sea‐level contribution. However, it remains unclear whether their ice loss is driven by anomalously warm present‐day ocean conditions, perhaps linked to anthropogenic climate change, or are an ...

Derivation of bedrock topography measurement requirements for the reduction of uncertainty in ice-sheet model projections of Thwaites Glacier [PDF]
The Cryosphere, 2022 Determining the future evolution of the Antarctic Ice Sheet is critical for understanding and narrowing the large existing uncertainties in century-scale global mean sea-level-rise (SLR) projections.

Widespread seawater intrusions beneath the grounded ice of Thwaites Glacier, West Antarctica. [PDF]
Proc Natl Acad Sci U S ASignificance We present evidence for seawater intrusions occurring at tidal frequencies over many kilometers beneath the grounded ice of Thwaites Glacier, West Antarctica, a major contributor to sea level rise.
