Abstract
Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Western Port Sunkland Victoria, Gravity (P197430) contains a total of 741 point data values acquired at a spacing of 805 metres. The data is located in VIC and were acquired in 1974, under project No. 197430 for University of Melbourne.

This Western Port Sunkland Victoria, Gravity (P197430), gravity point data contains ground gravity point data for the Western Port Sunkland Victoria, Gravity (P197430) survey acquired for University of Melbourne. This dataset contains a total of 741 point data values. The data is located in VIC and were acquired in 1974. The point located data were collected in traverses layout at an average station spacing of 805 metres. Terrain corrections were calculated using the INTREPID Geophysics software package. The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose. All data are provided in EPSG:4283 coordinates, Australian Height Datum (AHD) and gravity datum of AAGD07. The units are degrees, meters, and micrometres per second squared, respectively.
