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 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.

A contoured (interval 20m) general reference map of the island showing settlement, mining areas, railways, roads and tracks of Norfolk Islands.

At 1:15,000 scale, this map is larger than previous editions. It is printed on both sides, with the reverse portraying colourful photographs and text describing Norfolk Islands flora and fauna, history, things to do and see etc. This map is sold as a flat or folded product through Geoscience Australia`s Sales Centre or our map retailers, located throughout Australia.

This CD-ROM contains a rudimentary Norfolk Island GIS created by AGSO in 2001 for the Department of Transport and Regional Services to aid in the divestment of Commonwealth lands. This disk contains relevant cadastre, ArcExplorer projects, National Capital Authority planning documentation and data, and suggestions for further work.

In June 1980 the Department of Housing and Construction (DHC) completed a report on the proposed water supply iand swerage project for Norfolk Island (Goldfinch & Cross, 1980). This report requested that the Bureau of Mineral Resources (BMR) implement the following recommendations: 1. Undertake hydrogeological investigations on Norfolk Island as recommended in a Groundwater reprot on Norfolk Island (Abell, 1976). 2. Undertake investigations, drilling and testing as appropriate to provide observation and production bores in either or both of the Broken Bridge/Mission Creek valleys. A sufficient number of bores are to be drilled so that a production rate of not less than 10.4 L/sec is achieved with at least one bore in exess of minimum requirements to provide standby capacity. Each production bore is to be cased and fitted with screens. The main objective of the survey was a hydrogeological/geophysical investigation in the Broken Bridge - Mission Creek valleys leading to the selection of drill sites and recommendations on drilling to ascertain whether a groundwater supply at deeper levels on the island can be developed free of pollution from human or other agencies.
