Dataset includes information on all A- and B-ranked earthquakes (see Hansen et al., 2020) recorded by the Antarctic TAMNNET seismic array that were examined for ULVZ evidence. Information on their attenuation (t*) parameter, signal-to-noise ratio, core-mantle boundary bouncepoint location, and average remainder trace standard deviation are also provided. The provided figure indicates where ULVZ evidence has been found and where possible ULVZ evidence may be indicated.
