Adelaide Metropolitan Gravity (P197089), gravity point data

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 Adelaide Metropolitan Gravity (P197089) contains a total of 161 point data values acquired at a spacing between 200 and 1100 metres. The data is located in SA and were acquired in 1970, under project No. 197089 for Southern Alberta Institute of Technology (SAIT).

重力数据用于监测地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准流程处理，以确保记录得到的重力响应仅由地下岩石引起。经处理得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用要求。本次阿德莱德都会区重力数据集（编号P197089）共包含161组测点数据，测点间距介于200米至1100米之间。该数据集采集于南澳（SA），完成于1970年，隶属于阿尔伯塔省南部理工学院（Southern Alberta Institute of Technology, SAIT）编号为197089的项目。
