The sensitivity of the Antarctic ice sheet to a changing climate: Past, present, and future

TL Noble, EJ Rohling, ARA Aitken… - Reviews of …, 2020 - Wiley Online Library
Abstract The Antarctic Ice Sheet (AIS) is out of equilibrium with the current anthropogenic‐
enhanced climate forcing. Paleoenvironmental records and ice sheet models reveal that the …

The crust and upper mantle structure of central and West Antarctica from Bayesian inversion of Rayleigh wave and receiver functions

W Shen, DA Wiens, S Anandakrishnan… - Journal of …, 2018 - Wiley Online Library
We construct a new seismic model for central and West Antarctica by jointly inverting
Rayleigh wave phase and group velocities along with P wave receiver functions. Ambient …

Upper mantle structure of central and West Antarctica from array analysis of Rayleigh wave phase velocities

DS Heeszel, DA Wiens… - Journal of …, 2016 - Wiley Online Library
The seismic velocity structure of Antarctica is important, both as a constraint on the tectonic
history of the continent and for understanding solid Earth interactions with the ice sheet. We …

Influence of a West Antarctic mantle plume on ice sheet basal conditions

H Seroussi, ER Ivins, DA Wiens… - Journal of Geophysical …, 2017 - Wiley Online Library
The possibility that a deep mantle plume manifests Pliocene and Quaternary volcanism and
potential elevated heat flux in West Antarctica has been studied for more than 30 years …

Feedback mechanisms controlling Antarctic glacial-cycle dynamics simulated with a coupled ice sheet–solid Earth model

T Albrecht, M Bagge, V Klemann - The Cryosphere, 2024 - tc.copernicus.org
The dynamics of the ice sheets on glacial timescales are highly controlled by interactions
with the solid Earth, ie, the glacial isostatic adjustment (GIA). Particularly at marine ice …

The seismic noise environment of Antarctica

RE Anthony, RC Aster, D Wiens… - Seismological …, 2015 - pubs.geoscienceworld.org
Seismographic coverage of Antarctica prior to 2007 consisted overwhelmingly of a handful
of long running and sporadically deployed transient stations, many of which were principally …

Potential of the solid-Earth response for limiting long-term West Antarctic Ice Sheet retreat in a warming climate

H Konrad, I Sasgen, D Pollard, V Klemann - Earth and Planetary Science …, 2015 - Elsevier
We employ a coupled model for ice-sheet dynamics and Maxwell viscoelastic solid-Earth
dynamics, including a gravitationally consistent description of sea level. With this model, we …

Axial‐type olivine crystallographic preferred orientations: The effect of strain geometry on mantle texture

V Chatzaras, SC Kruckenberg… - Journal of …, 2016 - Wiley Online Library
The effect of finite strain geometry on crystallographic preferred orientation (CPO) is poorly
constrained in the upper mantle. Specifically, the relationship between shape preferred …

The seismic structure of the Antarctic upper mantle

DA Wiens, W Shen, AJ Lloyd - 2023 - pubs.geoscienceworld.org
The deployment of seismic stations and the development of ambient noise tomography as
well as new analysis methods provide an opportunity for higher-resolution imaging of …

FastIsostasy v1. 0–a regional, accelerated 2D glacial isostatic adjustment (GIA) model accounting for the lateral variability of the solid Earth

J Swierczek-Jereczek, M Montoya… - Geoscientific Model …, 2024 - gmd.copernicus.org
The vast majority of ice-sheet modelling studies rely on simplified representations of the
glacial isostatic adjustment (GIA), which, among other limitations, do not account for lateral …
