Sandringham Seismic, Gravity (P196536), 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 Sandringham Seismic, Gravity (P196536) contains a total of 318 point data values acquired at a spacing of 600 metres. The data is located in QLD and were acquired in 1965, under project No. 196536 for French Petroleum Co.

重力数据用于测量因地球表层下方岩石密度变化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，以确保记录的响应仅源自地下岩石。经处理得到的数据集可通过解译揭示地下地质构造。经处理后的数据集将由GA地球物理学家开展质量核验，以确保GA对外发布的最终数据符合使用要求。本桑德林汉姆地震-重力数据集（P196536）共计包含318组测点数据，测点间距为600米。该数据集采集于昆士兰州（QLD），采集时间为1965年，隶属于法国石油公司（French Petroleum Co.）编号为196536的项目。
