Measurements were taken at 15 to 60-minute intervals in real-time by the USGS and archived by NASA's GHRC DAAC.
Geoscience Australia released the 2014 version of its Marine Seismic Surveys Shape and KML files. The collection includes 3D exploration, 2D exploration, and 2D investigative seismic files, created from a cleansed and updated set of P190 navigation files following the UKOOA standard. The data is available for download in both KML and Shapefile formats.
Approximately 1.8 million gravity observations, including nearly 1.4 million ground stations and 451,000 line km of airborne surveys, were used to generate this grid. The data, compiled by Geoscience Australia and sourced from government, industry, and research organizations from the 1940s onward, reveals sub-surface geological structure. The final 2019 grid has a cell size of 0.00417 degrees (approximately 435m) and applies a tilt filter to de-trended global isostatic residual anomalies.
A gravity anomaly grid derived from approximately 1.8 million ground and offshore gravity observations.
