Data from 50 sonobuoys were recorded over the Capel and Faust Basins, 800 km to the east of Australia in water depths 1500-2000 m, during a 2006/07 seismic survey (GA302) for Geoscience Australia's New Oil initiative. These data were interpreted and forward modelled by ray-tracing to provide an estimate of P-wave velocities in the upper sedimentary section, and hence constrain estimates of sediment thickness. Also recorded were gravity and magnetic anomaly data which, in conjunction with the very high quality seismic reflection data, provided additional constraints upon the velocity models. The preliminary seismic reflection records studied are typified by four sets of reflection patterns: I) a ~500m thick sequence just below sea floor, II) a highly reflective flat-lying set of reflectors of variable thickness lying unconformably over III) a discontinuous, dipping, deformed sequence penetrated by high-amplitude events, and IV) deepest sequence generally marked by onset of high amplitude events. Typical ranges in four model layers below water were: 1.9, 2.3-3.0, 3.6-4.7, 5-5.3 km/s. Gravity models based on these results were compared to features identified on depth converted seismic reflection lines and indicate that sediment thickness at densities approximating 2.3 t/m3 (typically including sequences I-III) may reach 5 km in several localities.

This is a post-cruise report for the collaborative Australia/France searfloor mapping survey east of Norfolk Island. Regional settings, survey design and preliminary results are discussed.

This map was produced as part of a 2006 series depicting Australian commonwealth fisheries and shows the area of the Norfolk Island Offshore Demersal Finfish Fishery. The series of pdf's are for public download from AFMA's website and the shapefiles for public download from GA's website.

This dataset contains polygon cadastral data and non-spatial attribute data for the Norfolk Island. The dataset contains portion numbers and can be used to identify land ownership and in particular, information about Commonwealth owned land.
