The influence of realistic 3D mantle viscosity on Antarctica's contribution to future global sea levels

N Gomez, M Yousefi, D Pollard, RM DeConto… - Science …, 2024 - science.org
The response of the Antarctic Ice Sheet (AIS) to climate change is the largest uncertainty in
projecting future sea level. The impact of three-dimensional (3D) Earth structure on the AIS …

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 …

Seismic structure of the Antarctic upper mantle imaged with adjoint tomography

AJ Lloyd, DA Wiens, H Zhu, J Tromp… - Journal of …, 2020 - Wiley Online Library
The upper mantle and transition zone beneath Antarctica and the surrounding oceans are
among the poorest‐imaged regions of the Earth's interior. Over the last 15 years, several …

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
