While the separate results from the ambient noise and teleseismic tomography of WOMBAT array data has yielded important information in their own right, further valuable insight into lithospheric structure may be possible via a detailed comparison of contiguous crust and upper mantle structure from the two sets of tomography results. While a joint inversion of ambient noise and teleseismic data may in some circumstances be beneficial, the lack of spatial overlap between the WOMBAT teleseismic and ambient noise datasets means that there is unlikely to be any gain in this case. The teleseismic dataset is capable of resolving structure to a minimum depth of about 50 km, while the maximum depth of resolution of the ambient noise dataset is around 30–35 km. Thus, a small gap still needs to be filled by the AuSREM Moho and mantle model.
