This full seismic waveform inversion of the african plate was constructed using the combination of spectral element wavefield simulations, adjoint techniques and stochastic mini batch optimisation. Here, we show how global full waveform inversion is less sensitive to source receiver geometry and reveals numerous previously undetected positive wave speed anomalies in the lower mantle.

Full waveform inversion (fwi) estimates a spatially variable model of subsurface parameters; most commonly a model of the interval velocity, using an iterative data fitting workflow. Seismic interferometry and seismic data interpolation methodologies enable the acquisition of high fidelity seismic datasets, which facilitate full waveform inversion (fwi) to resolve high resolution subsurface velocity structures. In this paper, we explore the application of the measure of misfit that is provided by adaptive waveform inversion (awi), introduced by warner and guasch (2014, 2016), to a 3d anisotropic field data set, and we show that this can have significant advantages over more established measures. The full waveform inversion (fwi) utilizes full wavefield data to invert subsurface parameters and is considered one of the most promising data driven tools for obtaining high precision velocity models.
