  • These data represent whole rock geochemical analyses from the OZCHEM Database. Each analysis includes a geographic location and a geological description, which includes the host stratigraphic unit, where known, and the lithology. Most samples have been collected by Geoscience Australia field parties. These data are a snapshot at the "Ending Date" of the current database entries and are also a subset of the full database managed by GA which includes data from Papua NewGuinea, Antarctica, Solomon Islands and New Zealand.

  • The Australian Tsunami Database (ATDB) was commissioned by the Australian Geological Survey Organisation as part of a national database of natural hazards in Australia. Its scope, however, is broader with data for the Southwest Pacific, Southeast Asia and Australia. The ATDB aims to furher understanding of the tsunami hazard in these regions by presenting the data from myriad source in a single comprehensive resource that is both accessible and useful. The ATDB is constructed in Borland Paradox for Windows, a relational database that facilitates easy data entry and data extraction. The ATDB contains information regarding tsunami dates, time, locations, effects and comments, and is designed so that it can be linked to the earthquake database run by teh Australian Seismological Centre.

  • These data are the time series seismograph, hydroacoustic and infrasound data recorded from Australian National Seismograph Network (ANSN) observatories in Australia, islands in the Pacific, Southern and Indian Ocean's and the Australian Antarctic Territory. ANSN observatories include facilities operated by Geoscience Australia in collaboration with other international agencies. These data are acquired for the purpose of the detection and location of earthquakes and tsunamigenic events within the Australian continent and its surrounds. The dataset is also used to meet a subset of Australia's obligations to the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) to fulfil Australia's commitment to nuclear explosion monitoring. The seismic waveform data records seismic events to allow for the detection, location estimation (position and depth) and magnitude of earthquakes of magnitude of 3.0 or greater anywhere in Australia. Seismic (Digital). Seismograms (Physical plots (paper & film) and Digital Scans).

  • The collection includes 17,247 measurements of temperature and temperature gradients collected down 5513 individual wells. This information formed the basis for the 'OZTemp Interpreted Temperature at 5km Depth' image of Australia <b>Value: </b>These observations are used to assess heat flow which can be used to infer deep geologic structure, which is valuable for exploration and reconstructions of Australia's evolution <b>Scope: </b>Nationwide collection corresponding to accessible boreholes and published measurements

  • This is an extract from the OZTemp database, an updated and improved version of the AUSTHERM05 borehole temperature database previously described by Chopra and Holgate (2005). OZTemp currently contains 5513 individual wells and 17 247 temperature and/or temperature gradient data records.

  • Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The gravity data collection contains both onshore and offshore data acquired on geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

  • This Dataset has been collected over many decades for datum development and local monitoring purposes. It consists of measured angles, distances and height differences between monumented survey marks.

  • The geomorphic features of the seafloor in the Australian Marine Jurisdiction were identified using the Australian Bathymetry and Topography dataset (Webster & Petkovic 2005). Twenty one feature types were identified and mapped for an area including the seafloor surrounding the Australian mainland and island territories of Christmas, Cocos (Keeling), Macquarie, and Norfolk Islands (Heap & Harris 2008). Some examples of these geomorphic features include: abyssal plains, trenches, canyons, and seamounts.
