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.

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.

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.

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.

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.

Norfolk Island in the southwest Pacific Ocean has an area of 35 k m2 and rises to an altitude of just over 300 m. It is an erosional remnant of a volcanic complex consisting of subaerial basaltic lava flows and pyroclastics built on a submarine pile of hyaloclastite deposits and pillow lavas. A deep weathering profile has developed in the volcanic succession since eruptive activity ceased during the late Pliocene 2.3 Ma ago. Throughout the island there is an upper water table aquifer in porous alluvium and weathered basaltic rock. At the base of the weathered profile groundwater moves towards sea level through a complex network of fractures and other interconnected openings in volcanic bedrock. Semi-confined aquifers occur in fractured basalt flows and interbedded basaltic pyroclastics (tuffs and agglomerates). However, the extent and quality of deep groundwater below sea level needs more evaluation. The groundwater storage on Norfolk Island is tapped by more than 450 wells and bores.

This map has been created to update the old Crimes at Sea maps produced in 2000. These maps have been checked & approved by the Attorney Generals Office April 2013. There are 13 maps in the series plus the main map showing all of the Australian Territory. The AAT maps have not been released to the public as yet.

The data obtained from the NCA were prepared for planning recomendations made in 1996. The data contains 1996 spatial information of cadastre, land tenure, roads, reserves, 5m contours, terrain features, slope classes, the sewer catchment area, tourist accomadation, development areas, planning subdivison codes, portion areas, proposed plans for 1996, 1985 and 1972, and the KAVHA viewshed. The data covers the entire island and does well to decribe the physical features of the island.
