Abstract

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).
