Gravity Survey along Seismic Traverses (P197758), 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 Gravity Survey along Seismic Traverses (P197758) contains a total of 281 point data values acquired at a spacing of 200 metres. The data is located in SA and were acquired in 1977, under project No. 197758 for None.

重力数据用于观测地球表层下方岩石密度变化所引发的微小重力变化。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源自地下岩石的影响。经处理后可生成数据集，对该数据集进行解译能够揭示地下地质构造。GA的地球物理学家将对处理后的数据开展质量核查，以保障GA发布的最终数据符合使用要求。本次沿地震测线实施的重力测量项目（编号P197758）共计包含281个测点数据，测点间距为200米。数据采集区域位于南澳大利亚（SA），采集工作于1977年完成，隶属于编号197758的项目，无明确委托方。
