Heterogeneous melting near the Thwaites Glacier grounding line [PDF]

Nature, 2023
AbstractThwaites Glacier represents 15% of the ice discharge from the West Antarctic Ice Sheet and influences a wider catchment1–3. Because it is grounded below sea level4,5, Thwaites Glacier is thought to be susceptible to runaway retreat triggered at the grounding line (GL) at which the glacier reaches the ocean6,7.

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.

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.

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

Nat Geosci, 2022
Abstract 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. Of particular concern is how the glacier grounding zone might evolve over coming decades where it is stabilized by sea-floor bathymetric highs. Here we

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.

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

Nature, 2023
AbstractThwaites Glacier is one of the fastest-changing ice–ocean systems in Antarctica1–3. Much of the ice sheet within the catchment of Thwaites Glacier is grounded below sea level on bedrock that deepens inland4, making it susceptible to rapid and irreversible ice loss that could raise the global sea level by more than half a metre2,3,5.

Bedforms of Thwaites Glacier, West Antarctica: Character and Origin [PDF]

Journal of Geophysical Research F: Earth Surface, 2021
AbstractBedforms 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 basins.

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 ...

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.
