Seismic line 1 - Birksgate Gravity (P199303), 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 Seismic line 1 - Birksgate Gravity (P199303) contains a total of 414 point data values acquired at a spacing of 235 metres. The data is located in SA and were acquired in 1993, under project No. 199303 for Australian Geological Survey Organisation (AGSO).

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开展处理，以确保记录的响应仅源自地下岩石的影响。经处理得到的数据集可通过解译，揭示地下地质构造特征。经处理的数据将由AGSO地球物理学家开展质量核查，以确保AGSO发布的最终数据符合使用要求。本数据集为地震测线1——伯克斯盖特重力（P199303），共包含414个测点数据，测点间距为235米。该数据采集于南澳大利亚州（SA），于1993年为澳大利亚地质调查局（Australian Geological Survey Organisation，AGSO）编号为199303的项目采集所得。
