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 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.

The ANZLIC Metadata tool uses the ISO 19139 (2005) metadata standard which is the current supported metadata standard used in Australia in its ArcGIS Desktop version 10.5 software package. This metadata tool is intended to be used through the ArcGIS Desktop version 10.5 software accessed via the description tab in ArcCatalog. The tool was previously developed and supported by Esri Australia but this was formally handed over to ANZLIC in 2017. Geoscience Australia in support of ANZLIC has developed this new metadata tool based on the previous work of Esri Australia and the new Esri Inc ArcGIS Desktop 10.5 Metadata toolkit. The tool is intended for users of Esri Inc ArcGIS Desktop version 10.5 software to create ANZLIC compliant ISO 19139 metadata associated with datasets.

This software supports GeoSCiML and was developed by GA and is called Fullmoon. This software will hosted on CSIRO's SEEGRID Site.

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.

We have completed a new Web interface that makes it easier for AGSO's clients to find and order products sold by the AGSO Sales Centre. The new system is on AGSO's Web site at http://www.agso.gov.au/databases/catalog /html. Alternatively, from AGSO's home page at http://www.agso.gov.au, click on the `Products' button and select `AGSO Products' from the pull-down menu of online databases. The new interface is similar to the `Products Database' it replaces, but is based on the `AGSO Catalog', a new metadata system designed to keep track of all of AGSO outputs - including products, publications, datasets and resources. The new interface will be followed shortly by a Web interface for finding publications, papers and articles by AGSO staff members.

This report provides detailed metadata for the 37 marine physical environmental variables that were collated or specifically generated by the Marine Biodiversity Hub, which is part of the Commonwealth Environment Research Facilities Program. The work was done at Geoscience Australia and the Marine and Atmospheric Division of CSIRO. The data are required for use in the Hub's surrogacy and predictive modelling research. Bathymetry, geomorphology, seabed sediment and seabed exposure data were produced by Geoscience Australia. Bottom-water and surface-water parameters were produced by CSIRO. For each variable there is a general description, comprehensive metadata and a distribution map. All data were transformed to a common datum, WGS84, and converted to a grid with a cell size of 0.01 degrees. The metadata reports conform to ANZLIC standards. The data fall into five categories: 1. Bathymetry and geomorphology, derived from the 250 m resolution National Bathymetry Grid at Geoscience Australia; 2. Seabed sediments, derived from the MARS database at Geoscience Australia; 3. Seabed exposure, produced from the output of a seabed shear stress model, GEOMACS, at Geoscience Australia; 4. Bottom-water nutrients and temperature, extracted from the CARS database at CSIRO; 5. Surface-water parameters, derived from satellite images at CSIRO.

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.
