Geoscience Australia houses one of the world's largest collections of petroleum data. Much of this data is non-confidential and available to the petroleum industry, research organisations and the public. The collection includes seismic survey data submitted by industry under legislative requirements as well as data collected by research projects and marine surveys undertaken by Geoscience Australia or other government agencies or institutions. The collection comprises digital 2D and 3D seismic survey field data, navigation data, processed data, velocity data, observer's logs, operational reports, processing reports, bathymetry data, potential field data (gravity and magnetic) and also hard-copy data submitted during the pre-digital era including seismic sections and other analogue formats <b>Value: </b> Data used for interpreting the geologic structure of the subsurface. This work can be used for the assessment of resource potential. <b>This data can be discovered through the National Offshore Petroleum Information Management System (NOPIMS) - https://www.ga.gov.au/nopims</b>

Collection of Geoscience Australia's high-resolution elevation surveys collected using Light Detection and Ranging (LiDAR) and other instrument systems. <b>Value: </b>Describes Australia's landforms and seabed is crucial for addressing issues relating to the impacts of climate change, disaster management, water security, environmental management, urban planning and infrastructure design. <b>Scope: </b>Selected areas of interest around Australia.

The Australian National Exposure Information System (NEXIS) collates the best publicly-available information, statistics, spatial and survey data into comprehensive and nationally-consistent exposure information datasets. Where data is limited, models are used to apply statistics based on similar areas. Exposure Information products are created at the national, state or local level to understand the elements at risk during an event or as a key input for analysis in risk assessments. <b>Value: </b>NEXIS products are not intended for operational purposes at the building or individual feature level. Its strength is to provide consistent aggregated exposure information for individual event footprints or at standard community, local, state and national geographies such as the Australian Bureau of Statistics (ABS) Statistical Areas (SA) or Local Government Areas (LGA). <b>Scope: </b>National detailed exposure information of the number of people, dwellings, other buildings and structures, businesses, agricultural and environmental assets. Further information can be found at the following URL: https://www.ga.gov.au/scientific-topics/community-safety/risk-and-impact/nexis

Descriptions of and measurements from field sites and samples from geological (including regolith) surveys. <b>Value: </b>Used to constrained surface geology, important in resource exploration and understanding physical environment. <b>Scope: </b>Mapping surveys mainly in Australia, but also in Antarctica, Oceania and south-east Asia.

Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Department of Environment and Natural Resources within the Northern Territory Government (DENR) undertook collaborative seabed mapping surveys (GA0351/SOL6187, GA4452/SOL6432 and combined GA0361 & GA0362) in the Darwin-Bynoe Harbour region between 2015 and 2018. This seabed mapping project forms a core component of a four-year collaborative research program between DENR, GA and AIMS, which was funded by the INPEX-operated Ichthys LNG Project to DENR, with co-investment by GA and AIMS. The purpose of the program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions through the collation and acquisition of baseline data that enable the creation of habitat maps to better inform marine resource management decisions. Mapping and sampling in the survey area utilised multibeam echosounders, sub-bottom profilers, underwater cameras and grab samplers. In total, this data package extends over an area of 1978 km2, including 1754 km2 mapped using multibeam echosounders, during four marine surveys over 247 days. The baseline environmental data acquired in this program provides new insights into the marine environments of the Greater Darwin and Bynoe Harbour region, will inform future environmental assessments in the region and help build our knowledge of seabed features and processes in tropical northern Australia.

The SDE Best Available Geographic Database (SBAGD) is a historic database comprising the GEODATA TOPO 250K Series 3 data and any updates that were made from 2008-2013. This vector data represents major topographic features and has been sourced through many programs such as the National Topographic Information Coordination Initiative (NTICI). The topographic data complies with the Topographic Data and Map Specifications for the National Topographic Database & NTMS Series 1:250 000 & 1:100 000 scale topographic map products version 6.0.

Geoscience Australia houses one of the world's largest collections of petroleum data. Much of this data is non-confidential and available to the petroleum industry, research organisations and the public. The collection includes well data submitted by industry under legislative requirements as well as data collected by research projects and marine surveys undertaken by Geoscience Australia or other government agencies or institutions. The collections comprise of digital data such as well completion reports, well logs, destructive analysis reports, vertical seismic profiles, core photography, special studies and also hard-copy well log data and graphs submitted during the pre-digital era. <b>Value: </b> information related to the subsurface that have the potential to support geological investigations and assessment of a variety of resources. <b>This data can be discovered through the National Offshore Petroleum Information Management System (NOPIMS) - https://www.ga.gov.au/nopims</b>

Digital Elevation Model data record the terrain height variations from the processed point-located data recorded on an airborne geophysical survey. The aircraft altimeter data records the height of the aircraft above the ground and the aircraft GPS records the height of the aircraft above the ellipsoid. Subtracting the two values enables the height of the terrain beneath the aircraft relative to the ellipsoid to be calculated. This ellipsoidal terrain height is corrected for the variation between the ellipsoid and the geoid (the n-value correction) to produce terrain heights relative to sea level.

The BMR Yearbooks followed on from and retained the format of the final BMR Annual Report. The 1977 yearbook did not use that word in its title, which was simply BMR77. Later volumes followed this pattern, but added the subtitle: Yearbook of the Bureau of Mineral Resources, Geology and Geophysics, and in common usage they became known as the BMR (later AGSO) Yearbooks.
