Geophysics is built upon indirect information. We cannot travel deep into the Earth to directly measure rheological properties, nor journey back through geological time to record the planet’s tectonic evolution. Instead, we must draw inferences from whatever observations we can make, constrained as we are to the Earth’s surface and the present day. Inevitably, such datasets are sparse, incomplete, and contaminated with signals from many unknown events and processes. We therefore rely on a…

Bayesian inversion using nested trans-dimensional Gaussian processes
TLDR
In this work, it will be shown that in order to make accurate inferences about earth properties, inferences can first be made about the underlying length scales of these properties in a very general solution basis.
Transdimensional inference in the geosciences
TLDR
Concepts of transdimensional inference are introduced to a general readership and illustrate with particular seismological examples.
Mapping the upper mantle: Three‐dimensional modeling of earth structure by inversion of seismic waveforms
A method is presented for the inversion of waveform data for the three-dimensional distribution of seismic wave velocities. The method is applied to data from the global digital networks
Earth models consistent with geophysical data
Abstract A suite of the most recently available geophysical data are inverted by an improved Monte Carlo procedure. The data are derived from surface waves for oceanic paths, eigenvibrations of the
Probabilistic inversion of seafloor compliance for oceanic crustal shear velocity structure using mixture density neural networks
Measurements of various physical properties of oceanic sediment and crustal structures provide insight into a number of geological and geophysical processes. In particular, knowledge of the shear
The Spectral-Element Method, Beowulf Computing, and Global Seismology
The propagation of seismic waves through Earth can now be modeled accurately with the recently developed spectral-element method. This method takes into account heterogeneity in Earth models, such as
Bayesian trans-dimensional full waveform inversion: synthetic and field data application
Seismic full waveform inversion (FWI) is a state-of-the-art technique for estimating subsurface physical models from recorded seismic waveform, but its application requires care because of high
Upper mantle structure of Mars from InSight seismic data
TLDR
The seismic constraints with geodynamic models predict that, relative to the primitive mantle, the crust of Mars is more enriched in heat-producing elements by a factor of 13 to 20 and has a moderate-to-elevated surface heat flow.
Global seismic tomography using Backus–Gilbert inversion
S U M M A R Y The appraisal of tomographic models, of fundamental importance towards better understanding the Earth’s interior, consists in analysing their resolution and covariance. The discrete
An optimal transport approach to linearized inversion of receiver functions
Receiver function analysis is widely used to make quantitative inferences about the structure below a seismic station. As these observables are mainly sensitive to traveltimes of phases converted and
