Gravity Anomaly Map of the Australian Region, 3rd edition, 2008

Gravity anomaly map of the Australian Region 3rd edition. This map is derived from an image which combined onshore Bouguer gravity anomaly and offshore freeair anomaly values. Onshore Bouguer gravity anomalies were calculated from over 1.4 million observations held in the the Australian National Gravity Database. Offshore freeair anomaly data were derived from satellite altimetry data available from Scripps Institution of Oceanography. This data is used to study the tectonic structure of Australia by mapping variations in the earth's gravimetric field. The 'hotter colours' (eg red) show areas of stronger gravity field and the 'cooler colours' (eg dark blue) show areas of weaker gravity field. Gravity data used to produce the Gravity Anomaly Map of the Australian Region are available for free download via the Geophysical Archive Data Delivery System (GADDS).

Australian Gravity Anomalies Image cached map service (Web Mercator)

This image represents gravity anomalies of the Australian region. The grid combines accurate onshore gravity measurements, with satellite data over the offshore region. The cell values represent simple Bouguer anomalies at a density of 2.67 tonnes per cubic metre onshore and free-air anomalies offshore. The grid cell size is 0.5 minutes of arc, which is equivalent to about 800 metres.
