Over the past 10 years, Australia has maintained 65-85% self-sufficiency in oil and better than 100% suffiency in gas. This has generated significant societal benefits in terms of employment, balance of payments, and revenue. However the decline of the super-giant Gippsland fields, discovery of smaller oil pools on the Northwest Shelf, and the increasing reliance on condensate to sustain our liquids supply sharpens the focus on Australia's need to increase exporation and discover more oil. Australia is competing in the global market place for exploration funds but as it is relatively under-explored there is a need to simulate interest through access to pre-competitive data and information. Public access to exploration and production data is a key plank in Australian promotion of petroleum exploration acreage. Access results from legislation that initially subsidised exploration in return for lodgement and public availability of exploration and production (E&P) data. Today publicly available E&P data ranges from digital seismic tapes, to core and cuttings samples from wells, and access to relational databases, including organic geochemistry, biostratigraphy, and shows information. Seismic information is being progressively consolidated to high density media. Under the Commonwealth Government?s Spatial Information and Data Access Policy, announced in 2001, company data is publicly available at the cost of transfer, after a relatively brief confidentiality period. In addition, pre-competitive regional studies relating to petroleum prospectivity, undertaken by Government, and databases and spatial information is free over the Internet, further reducing the cost of exploration. In cooperation with the Australian States and the Northern Territory, we are working towards jointly presenting Australian opportunities through the Geoscience Portal (http://www.geoscience.gov.au) and a virtual one stop data repository. The challenge now is to translate data availability to increased exploration uptake, through client information, and through ever-improving on-line access.

PIMS, or the Petroleum Information Management System, is a database that keeps track of 376 000 seismic survey tapes and 2 800 petroleum well logs housed at the National Archives facility, at Chester Hill (formerly Villawood), Sydney - the largest tape archive in the southern hemisphere. PIMS is managed by AGSO's Petroleum Resources Program, which was formerly part of the Bureau of Resource Sciences. The survey tapes and well logs are basic data from petroleum exploration. They are loged under the Petroleum (Submerged Lands) Act, and are publicly available as a stimulus to further exploration.

OZCHEM is AGSO's national whole-rock geochemical database (previously known as ROCKCHEM). This documentation explains the database structure and includes definitions of the database tables and columns (attributes). It is provided with all purchases of OZCHEM data, but can also be purchased separately. The documentation includes summaries and highlights of all the regional data sets that comprise OZCHEM.

The Gravity Survey Index presents a summary of the essential specifications on about 1000 gravity surveys held in the National Gravity Database. Gravity measurements have been made in Australia since about 1900. Organised surveys for geophysical purposes (initially oil and coal exploration) have been conducted from 1939 onwards. The dataset includes surveys carried out by AGSO (BMR), state governments, private companies, universities and other organisations. The digital point data, maps and grids derived from these surveys are available as separate products. Additional to the survey index is the locations of the the Australian fundamental gravity network stations as a separate dataset.

This report provides detailed descriptions (metadata) of 45 Australian marine environmental datasets that have been generated and collated by the Marine Biodiversity Hub as part of Theme 3 - National Ecosystems Knowledge, Project 1 - Shelf and Canyon Ecosystems Functions and Processes. The report also includes a map for each dataset to illustrate coverage and general spatial structure. The datasets contain both marine environmental and biological variables from diverse data sources and include both new and updated information. Among them, the national bathymetry grid and derived products, seabed sediment grids, seabed exposure (GEOMACS) parameters, water quality data, the national canyon dataset and connectivity layers were produced by Geoscience Australia. Other environmental and biological datasets are the outputs of oceanographic models and collections of various governmental and research organisations. These datasets are important for the success of marine biodiversity research in Theme 3 Project 1 in that they describe key aspects of Australian marine physical, geochemical and biological environments. The physical and geochemical datasets not only characterise the static seabed features but also capture the temporal variation and three-dimensional interactions within marine ecosystems. The biological datasets represent a unique collection of fish and megafauna data available at the national scale. Together, these marine environmental datasets enhance our understanding of large-scale ecological processes driving marine biodiversity patterns. However, we should be aware of the uncertainties and potential errors exist in these datasets due to limitations of data collection and processing methods. Data quality issues of individual datasets have been documented in this report where possible.

The role of Geoscience Australia (GA) is to provide first class geoscientific information and knowledge which enables government and community to make informed decisions about: - the exploitation of resources - the management of the environment - the safety of critical infrastructure and - the resultant wellbeing of all Australians. GA has two internal catalogues which hold metadata of significant value to external researchers. The catalogues include national collections of satellite images/datasets; geological and topographical maps of various scales; Maritime, Aboriginal Commission and Postcode boundary datasets, plus other geoscientific thematic maps and collections. Staff from GA and ANDS worked together to analyse the catalogues, map them to the ISO19115 metadata schema and provide a gap analysis to inform further development. The original intention was to cross walk the 19115 profile to RIF-CS and install an OAI-PMH harvest point. ANDS, however, was able to utilise funded work by AuScope by having an instance of GeoNetwork deployed in GA, which provides this capability and can be leveraged to expose this data at the same time. This mapping also allows data of relevance to other disciplines such as that relevant to marine research to be identified and appropriate feeds established. The more significant achievement for GA was that it is now able to dynamically map from two existing independent internal catalogues to a single standards compliant instance, without having to first create a single internal catalogue and then migrate metadata from various catalogues into it. This approach will be used for other data types where GA has several internal databases of the same data type. This poster explores the issues that confronted the team, the solutions developed and the opportunities that have arisen.

The `AGSO Catalog' is a directory or metadatabase* of AGSO's outputs that includes products, publications, datasets and resources. Built using AGSO's corporate Oracle database management system, the Catalog evolved from an earlier `Products Database' that provided a web query and ordering system for all products sold by AGSO's Sales Centre. This function continues, with web interfaces to all products in the Catalog. However, the Catalog also covers external articles, papers and other publications by AGSO staff, datasets that may be either sold or given away, and corporate resources, such as maps, images and GIS datasets, many of which were purchased from outside the organisation. AGSO's web site now includes a Catalog interface for articles and other publications by AGSO staff. The Catalog is designed to capture metadata* at the source ? the author, project manager, research group leader or AGSO Division. Any staff member with an Oracle logon can initiate a new entry in the Catalog via Oracle data entry forms on AGSO?s intranet. The Catalog also facilitates business processes associated with the production of datasets, publications, etc. Various checks and `sign-offs? have been included for quality assurance and to prevent unchecked metadata from appearing on AGSO?s external web site. More business rules will be added as the need arises.

The fruits of geoscientists' labours are consigned increasingy to computer files. Although the capacities of electronic media are expanding rapidly, the means of keeping track of all these files is lagging. Knowledge-based organisations like AGSO need the electronic equivalent of libraries to house this information, the analogue of library catalogues to allow us to find critical bits, and the equivalent of librarians to manage the metadata. Files worth keeping must be kept permanently online, referenced by a metadatabase, visible on the Web, accessible from around the world, and in compliance with changing hardware, software and data standards.
