Where the network is sparse — much of the southern hemisphere, the oceans, and anywhere a monitoring problem is hardest — you may have one station and a few minutes. This work asks how well a single three-component record can constrain scalar moment, and more importantly how honestly the uncertainty on that estimate can be reported. A deep ensemble produces a predictive distribution rather than a point value, and the estimates are pooled across whatever stations happen to have returned data.https://bmoyer.net/work/gravity-magnetics/Mon, 17 Aug 2026 00:00:00 +0000https://bmoyer.net/work/gravity-magnetics/This page is a stub. Fuller writeup, figures, and code links to follow. Potential-field inversion is badly non-unique: many subsurface density and susceptibility distributions produce the same measurements at the surface. The usual response is to fix a parameterisation in advance and regularise toward it, which produces a tidy answer and hides the question of how much of that answer the data actually supports. Trans-dimensional Bayesian inversion treats the number of parameters as unknown and infers it alongside everything else, so the resolution of the result is a posterior quantity rather than a modelling choice.
