How sensitive is Thwaites glacier to ocean conditions?
In its present geometric configuration, the Thwaites Ice Shelf exerts only a limited influence on the upstream dynamics of Thwaites Glacier. Previous studies have demonstrated that ice flux across the grounding line is largely insensitive to the presence or absence of the ice shelf.G. Hilmar Gudmundsson +4 more

Seismic reflection surveys at GHOST Ridge, Thwaites Glacier
Subglacial topography and the character of a glacier’s basal material have a controlling effect on ice flow and are therefore important to parameterise in ice sheet models. Seismic surveys provide a means to characterise basal materials through the estimation of the elastic parameters of the bed (for example, acoustic impedance and Poisson ...Ronan Agnew +6 more

The melting underneath the Thwaites Glacier is complicated
Physics Today, 2023openaire +1 more source
The Thwaites Eastern Ice Shelf stands as the last remaining floating extent of the consequential Thwaites Glacier in West Antarctica. In the past, it has provided buttressing of the grounded glacier ice, but in the last decade the ice shelf has undergone significant weakening that has reduced its ability to buttress the glacier.

New insights into Hydrology and Lake Dynamics Upstream of Thwaites Glacier
Understanding Antarctic subglacial hydrology is crucial for assessing ice sheet dynamics and their contributions to global sea-level rise. Subglacial water modulates basal friction, influencing ice flow and glacier stability, as shown in studies of Thwaites Glacier and other West Antarctic systems.Felipe Napoleoni +6 more

Seismicity Insights Near the Eastern Shear Margin of Thwaites Glacier
Accelerated ice loss from Thwaites Glacier poses a potential threat to the stability of the West Antarctic Ice Sheet, making it a key contributor to future sea-level rise and a priority in Antarctic research. Seismic investigations have proven invaluable in glaciological research, enabling the examination of basal ice conditions, ice-bedrock ...Lucia Gonzalez +8 more
