Scripts for null space exploration using gravity data: application to field data from the Western Pyrenees and synthetic example.
Authors/Creators
Description
This repository contains two archives showing examples of usage of the null-space exploration code used in:
Giraud, J., Ford, M., Caumon, G., Ogarko, V., Grose, L., Martin, R., and Cupillard, P.: Geologically constrained geometry inversion and null-space navigation to explore alternative geological scenarios: a case study in the Western Pyrenees, Geophysical Journal International, https://doi.org/10.1093/gji/ggae192, 2024.
The implementation is based on the "nullspace shuttles" algorithm introduced by, and described in:
Fichtner, A. and Zunino, A.: Hamiltonian Nullspace Shuttles, Geophysical Research Letters, 46, 644–651, https://doi.org/10.1029/2018GL080931, 2019.
The archive GeoMos_nullspace-paper_example.zip contains the necessary files to reproduce the work presented in Giraud et al. (2024).
The archive GeoMos_nullspace-3D_synthetic.zip contains a smaller, synthetic example using noisy data where the perturbation consists of a sphere being inserted in a model already containing another sphere.
For assistance in running these scripts or for questions about them, their use, etc. please contact jeremie.giraud@uwa.edu.au
