Datasets used to condition inversions of shear stress at the ice-bed interface on Thwaites Glacier

, 2022
Included in this handle are input data used in the inversions described in the paper "The impact of basal roughness on Thwaites Glacier sliding." These include surface elevation, and basal topographies used to construct the meshes that define the ...

Polarimetric multi-offset radio-echo sounding with a radio frequency-over-fiber ApRES system

Journal of Glaciology
Polarimetric multi-offset radio-echo sounding offers improved constraints on englacial thermal conditions, basal properties and ice crystal orientation compared to standard monostatic observations.

Inferring Glaciological Attributes of Thwaites Glacier Using GPS-Interferometric Reflectometry and Precise Point Positioning [PDF]

, 2019
We use two continuous GPS stations located on Thwaites glacier to estimate the rate of snow accumulation through GPS interferometric reflectometry and separately examine details of the motions of the glacier.

Thwaites Glacier bedrock topography measurement requirement characterization code

, 2021
This code assists in setting up the first three experiments ran in Castleman et al. (2021) using ISSM (Larour et al., 2012b). This includes the minimum and maximum tests (Sec. 3), spatial resolution tests (Sec. 4.1), and vertical resolution tests (Sec. 4.2). Furthermore, code for producing some of the figures included in the paper is also provided.

A new, fast and unified subglacial hydrological model applied to Thwaites Glacier, Antarctica

Subglacial hydrology is a crucial element for understanding the dynamics of marine ice sheets. Indeed, the presence of subglacial water modulates the ice basal motion, resulting in a modified ice flow across the entire ice sheet. Nonetheless, the subglacial environment is difficult to reach, which makes it necessary to develop models. Many efforts have
