This animation shows how Reflection Seismic Surveys Work. It is part of a series of Field Activity Technique Engagement Animations. The target audience are the communities that are impacted by our data acquisition activities. There is no sound or voice over. The 2D animation includes a simplified view of what reflection seismic survey equipment looks like, what the equipment measures and how the survey works.

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>

To improve understanding of basins and basement structures, and of the energy, mineral and groundwater resource potential of northern Australia, deep crustal seismic surveys were conducted, totalling 2787 line-km, between June 2017 and November 2019 as a part of Exploring for the Future program. Reflection seismic profiles provide the highest fidelity imaging of crustal-scale subsurface architecture and therefore have become the industry standard for energy exploration, and their use in mineral and groundwater applications is growing. Here, we document the acquisition of composite deep reflection seismic profiles (20 sec, ~60 km depth). The focus is on imaging new terranes, and resolving frontier basin and crustal architecture. Seismic data were acquired stretching from the Beetaloo Sub-basin to the Mt Isa western succession in the Northern Territory and Queensland, as well as in the Kidson Sub-basin in Western Australia. Raw data for these surveys are available on request from clientservices@ga.gov.au, and processed data are publicly available from the Geoscience Australia website at https://www.ga.gov.au/about/projects/resources/seismic. <b>Citation:</b> Fomin, T., Holzschuh, J., Costelloe, R.D., and Henson, P., 2020.
