Glacial isostatic adjustment and postseismic deformation in Antarctica (2022)
Journal Article
van der Wal, W., Barletta, V., Nield, G., & van Calcar, C. (2023). Glacial isostatic adjustment and postseismic deformation in Antarctica. Memoirs, 56(1), https://doi.org/10.1144/m56-2022-13

This chapter reviews glacial isostatic adjustment (GIA) and post-seismic deformation in Antarctica. It discusses numerical models and their inputs, and observations and inferences that have been made from them. Both processes are controlled by mantle...

A global, spherical finite-element model for post-seismic deformation using Abaqus (2022)
Journal Article
Nield, G. A., King, M. A., Steffen, R., & Blank, B. (2022). A global, spherical finite-element model for post-seismic deformation using Abaqus. Geoscientific Model Development, 15(6), 2489-2503. https://doi.org/10.5194/gmd-15-2489-2022

We present a finite-element model of post-seismic solid Earth deformation built in the software package Abaqus (version 2018). The model is global and spherical, includes self-gravitation and is built for the purpose of calculating post-seismic defor...

GPS-observed elastic deformation due to surface mass balance variability in the Southern Antarctic Peninsula (2022)
Journal Article
Koulali, A., Whitehouse, P., Clarke, P., van den Broeke, M., Nield, G., King, M., Bentley, M., Wouters, B., & Wilson, T. (2022). GPS-observed elastic deformation due to surface mass balance variability in the Southern Antarctic Peninsula. Geophysical Research Letters, 49(4), Article e2021GL097109. https://doi.org/10.1029/2021gl097109

In Antarctica, Global Positioning System (GPS) vertical time series exhibit non-linear signals over a wide range of temporal scales. To explain these non-linearities, a number of hypotheses have been proposed, among them the short-term rapid solid Ea...
