The airborne geophysics data set contains approximately 34 million line kilometres of data, which, at current prices, would cost approximately $197 million to acquire. The gravity data set contains more than 1.57 million reliable onshore stations gathered during more than 1800 surveys. The collection also includes a large number of seismic surveys from Australia's offshore basins. The onshore component of this data set was previously approved for RDSI for 8 TB. This proposal extends the collection to 150TB. The data types and access methods for the Offshore and Onshore data are identical Certain holdings are additionally hosted at the NCI (see downloads) {"type": "Polygon", "coordinates": [[[112.717, -43.76], [153.67, -43.76], [153.67, -9.0], [112.717, -9.0], [112.717, -43.76]]]} 112.717 153.67 -43.76 -9.0 Airborne Electromagnetics DC2020 Earth Sciences Geophysics Gravity Magnetics Magnetotellurics NCI Published_External Radiometrics Seismic neii.gov.au Link to Geophysical Archive Data Delivery System (GADDS) Portal documentDigital Link to Geophysical Archive Data Delivery System (GADDS) Portal HTML Link to NCI Holdings documentDigital Link to NCI Holdings HTML
