Fig. 3: Observed and synthetic seismic waveform data from OBS 57.
From: Lower oceanic crust formed by in situ melt crystallization revealed by seismic layering
a, The field data (black) and the synthetic waveform (red) using the tomographic model (Extended Data Fig. 1). b, The field data (black) and the synthetic waveform (red) using the true-amplitude FWI model (Fig. 2). Seismic waveforms from more OBSs can be found in Extended Data Figs. 3 and 4. A reduced travel time of 7 km s−1 velocity was applied to both the field and synthetic data.
