Contract Helicopter Gravity (P196610), gravity point data  

Authors / CoAuthors

Geophysical Acquisition & Processing Section

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 Contract Helicopter Gravity (P196610) contains a total of 3933 point data values acquired at a spacing between 4000 and 14000 metres. The data is located in QLD and were acquired in 1966, under project No. 196610 for Bureau of Mineral Resources (BMR).

Lineage

This Contract Helicopter Gravity (P196610), gravity point data contains ground gravity point data for the Contract Helicopter Gravity (P196610) survey acquired for Bureau of Mineral Resources (BMR). This dataset contains a total of 3933 point data values. The data is located in QLD and were acquired in 1966. The point located data were collected in irregular grid layout at a station spacing between 4000 and 14000 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.
