SA Detailed Gravity Survey 81S9 (P198155), 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 SA Detailed Gravity Survey 81S9 (P198155) contains a total of 305 point data values acquired at a spacing of 800 metres. The data is located in SA and were acquired in 1981, under project No. 198155 for None.

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动。所采集的数据将通过标准化流程进行处理，以确保记录得到的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对外发布的最终数据符合使用要求。本次南澳大利亚州（South Australia，简称SA）详细重力测量项目81S9（编号P198155）共包含305个测点数据，测点间距为800米。该数据采集于1981年，采集区域位于南澳大利亚州，隶属于编号198155项目，服务对象为无（None）。
