Seafloor Reveals a Period of Rapid Retreat for Thwaites Glacier

Eos, 2022
New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid ...

Knickpoint Morphology in Homogenous Substrates Controlled by Sediment Cover and Base‐Level Fall Rate

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Knickpoints can form spontaneously under constant forcing, without external perturbations. Flume experiments reveal three distinct morphologies, controlled by the balance between base‐level fall rate and sediment cover. A new conceptual model shows how erosion, sediment armouring and plunge pool dynamics govern knickpoint morphology, challenging ...

Teleseismic S‐Wave Coda Autocorrelation and vp/vs ${v}_{p}/{v}_{s}$ Distribution Over the Antarctic Ice Sheet

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

The Overprint of Transient Rheology on Laterally Heterogeneous Viscosity: Influences on Sea‐Level Change Driven by Antarctic Ice Sheet Loss

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Through bedrock deformation, solid Earth dynamics (specifically, glacial isostatic adjustment or GIA) influences ice sheet mass balance, especially for marine‐based ice sheets like the West Antarctic ice sheet (WAIS). As ice sheets retreat, crustal uplift can help stabilize a marine based ice sheet by reducing the ice exposed at the grounding ...

SWOT High‐Rate Raster Data Reveals Antarctic Ice Shelf Motion and Change in Response to Ocean and Ice Dynamics

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The NASA/CNES Surface Water and Ocean Topography (SWOT) swath‐mapping radar altimetry satellite mission, launched in December 2022, provides repeat‐track coverage to about ±78.2° latitude every 21 days, sampling many of Antarctica's most dynamic ice shelves that play key roles in constraining mass loss from the grounded ice sheet ...

Adaptively constraining radar attenuation and temperature across the Thwaites Glacier catchment using bed echoes

Journal of Glaciology, 2016
Englacial temperature is a major control on ice rheology and flow. However, it is difficult to measure at the glacier to ice-sheet scale. As a result, ice-sheet models must make assumptions about englacial temperature and rheology, which affect sea level

Retreat of Thwaites Glacier, West Antarctica, over the next 100 years using various ice flow models, ice shelf melt scenarios and basal friction laws [PDF]

The Cryosphere, 2018
Thwaites Glacier (TG), West Antarctica, has experienced rapid, potentially irreversible grounding line retreat and mass loss in response to enhanced ice shelf melting.
