Download the Residual Gravity Data
Download the entire open-file Tasmanian gravity database as residual anomaly data.

The residual anomaly is produced by correcting the Bouguer anomaly data for the effects of Moho topography and the bathymetry of the waters surrounding Tasmania at each observation point. (see MRVGP8, UR1988/08 and GPCR2009_01 for details).
 

Gravity Base Station Data

Gravity base stations may be searched textually and/or spatially to locate specific base stations.

Mineral Resources Tasmania maintains an index of gravity base stations that can be used as reference values for future surveys. The primary network was established by Geoscience Australia with subsidiary stations being established to facilitate later regional or detailed surveys.
