The seismic stacking-velocity data in the Great Australian Bight are a useful dataset for calculating depths and sediment thicknesses on a regional scale. This work compares these data with P-wave velocities from sonobuoys and sonic logs from wells, and on this basis, a depth over-estimate of at least 15% can be expected from the depths derived from stacking velocities. Megasequence boundary depths are calculated for the Ceduna Terrace to further illustrate data quality. The database makes available the unfiltered stacking velocities using conventional and horizon-consistent formats.
