The Collaborative Seismic Earth Model: Generation 1

Fichtner, Andreas, et al. (2018), The Collaborative Seismic Earth Model: Generation 1, Geophysical Research Letters, 45, doi:https://doi.org/10.1029/2018GL077338.

We present a general concept for evolutionary, collaborative, multiscale inversion of geophysical data, specifically applied to the construction of a first-generation Collaborative Seismic Earth Model. This is intended to address the limited resources of individual researchers and the often limited use of previously accumulated knowledge. Model evolution rests on a Bayesian updating scheme, simplified into a deterministic method that honors todays computational restrictions. The scheme is able to harness distributed human and computing power. It furthermore handles contradicting updates, as well as variable parameterizations of different model refinements or different inversion techniques. The first-generation Collaborative Seismic Earth Model comprises 12 refinements from full seismic waveform inversion, ranging from regional crustal- to continental-scale models. A global full-waveform inversion ensures that regional refinements translate into whole-Earth structure.
