The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

These data represent the OZCHRON database of physical age determinations of Australian rocks, and the radiogenic isotope ratios used in determining the ages. OZCHRON datasets comprise bibliographic references, analytical data and pooled results for samples derived using the Rb-Sr, SHRIMP, U-Pb, and Sm-Nd age determination methods.

"This dataset shows locations of seismic recording stations. It is generated from a database containing coordinates of all Geoscience Australia's seismic traverses. (related to GeoCat records 32386 and 32407)"

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.

The collection is derived from the submission of data under the Offshore Petroleum and Greenhouse Gas Storage Act (OPGGSA) and previous legislation. The Petroleum (Submerged Lands) Act (and the Offshore Petroleum Act & OPGGSA) requires petroleum data to be submitted to the State Designated Authority (DA). These Acts also require the DA's to make copies of the data/samples available to the Commonwealth Minister through the Joint Authority. The collection also contains cores, cuttings, paper reports, logs and stratigraphic cores drilled by BMR and a limited collection of water bores and engineering cores from around Canberra.

The offshore seismic data consists of field, processed, and seismic navigation data. Reports of the acquisition, processing and interpretation reports plus reprocessed seismic data and reports are also held. The collection is derived from the submission of seismic data under the Offshore Petroleum and Greenhouse Gas Storage Act and previous legislation. The Petroleum (Submerged Lands), the Offshore Petroleum, and the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA) requires petroleum data to be submitted to the State Designated Authority (DA). The Act(s) also require the DAs to make copies of the data available to the Commonwealth Minister through the Joint Authority.

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 Landsat series of satellites commenced acquiring remotely sensed data with the launch of Landsat 1 in 1972. The Landsat satellites travel at an altitude of 705 kilometres and provide coverage of the entire globe every 16 days. Landsat 5, launched in 1984, carries the Thematic Mapper (TM) sensor in addition to the Multispectral Scanner (MSS). The Thematic Mapper is a higher resolution sensor. It provides imagery in seven spectral bands (called Bands 1-7), covering the visible and near, middle and thermal infrared parts of the electromagnetic spectrum. TM has a 30-metre pixel resolution for all bands except Band 6 which has a 120-metre resolution. Its ground swath is 185 kilometres. A full scene is 185 kilometres by 172 kilometres. The archive of ACRES products includes TM data from September 1987 to December 1999 and July 2003 onwards.

MODIS (Moderate Resolution Imaging Spectroradiometer) is the key instrument aboard the satellites Terra (EOS AM-1), launched on 18 December 1999 and Aqua (EOS PM-1), launched on 4 May 2002. MODIS views almost the entire surface of the Earth every day, acquiring data in 36 spectral bands over a 2330 km swath. MODIS data will improve the understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. ACRES has been acquiring MODIS data since April 2000 and December 2002 from TERRA and ACQUA satellites respectively. Registered users can download this data free of cost from ACRES web site.

The National Spectral Database (NSD) houses data taken by Australian remote sensing scientists. The database includes spectra covering targets as diverse as mineralogy, soils, plants, water bodies and various land surfaces.<br /> Currently the database holds spectral information from multiple locations across the country and as the collection grows in spatial / temporal coverage, the NSD will service continental scale validation requirements of the Earth observation community for satellite-based measurements of surface reflectance. The NSD is accessed with information provided at the NSD Geoscience Australia Content Management Interface (CMI) web page: https://cmi.ga.gov.au/data-products/dea/643/australian-national-spectral-database <b>Value:</b> Curated spectral data provides a wealth of knowledge to remote sensing scientists. For other parties interested in calibration and validation (Cal/Val) of surface reflectance products, the Geoscience Australia (GA) Cal/Val dataset provides a useful resource of ground-truth data to compare to reflectance captured by Landsat 8 and Sentinel 2 satellites. The Aquatic Library is a robust collection of Australian datasets from 1994 to present time, primarily of end-member and substratum measurements. The University of Wollongong collection represents immense value in end-member studies, both terrestrial and aquatic. <b>Scope:</b> The NSD covers Australian data including historical datasets as old as 1994. Physical study sites encompass locations around Australia, with spectra captured in every state. <b>Data types:</b> - Spectral data: raw digital numbers (DN), radiance and reflectance. - From spectral bands VIS-NIR, SWIR1 & SWIR2: wavelengths 350nm - 2500nm collected with instruments in the field or lab setting.
