A marine seismic study and a resistivity study of marine sands in Broken Bay, Australia, showed that bedrock levels vary considerably, reaching ~ −90 m AHD in some areas and that surficial resistivity values ranged from 1.3 to 0.6 Ω m (20°C) with an average formation factor of 4.2.

A technique by which properties can be connected between 2D seismic lines is introduced in this paper. This interpretation workflow is then tested on a pilot area in a portion of the onshore Gippsland Basin, Australia. Calculated attributes and inverted seismic sections were fed into a 3D model in an attempt to track the sand filled channels and seals. The sealing sequence is characterised by distinctive log/seismic properties, which were modelled in 3D, and attempts are made to discuss seal potential in terms of geometry and integrity.

In many cultural heritage projects, it is often more important to ensure that burials are not disturbed rather than to specifically locate them. Under these circumstances, ground penetrating radar (GPR) can be used to locate modern anthropogenic fill. This may show which areas of the site are younger than the targeted graves and therefore of no archaeological interest. This approach is successfully trialled on a site in Albany, Western Australia. This approach, applied to suitable sites, could contribute to culturally sensitive non-invasive investigation of burial sites in other locations.

A mesoscale petrophysics and lithological logging study has been carried out on 413 core samples of the 623 m thick Narrabeen Group succession penetrated by the Eveleigh No. 1 diamond drillhole. Mass properties, magnetic susceptibilities, and electrical estimates of mobile salt (EC 1 : 5 tests) were measured. A physical properties analysis posits a 3-fold subdivision of the succession: basal fluvio-deltaic and alluvial, upper lacustrine, and topmost fluvio-deltaic. Each division has cyclic sedimentation but from different provenances. The analysis has proved useful in the correlation of the Narrabeen Group present in a series of drillholes in the eastern part of the exposed Sydney Basin.

Fuzzy Gustafson–Kessel cluster analysis is employed to integrate suites of disparate data sets. The fuzzy c-means algorithm is used as a reference to discuss the advantages of the Gustafson–Kessel algorithm and revise a database comprising airborne and ground-based geophysical data sets while minimising preparatory data processing required for fuzzy c-means cluster analysis.
