Reversal frequency model and ocean floor structure map.

Caption

The detailed geomagnetic reversal frequency model reconstructed in this study, geomagnetic polarity time scale (drawn using data from Ogg, 2020, Geologic Time Scale 2020, Elsevier), and the Earth's ocean floor structure map with ages of missing reversals (drawn using data from Müller et al., 2019, Tectonics). The colored bands indicate the ocean floor at times when high-resolution surveys are needed to detect missing geomagnetic reversals.
