Polda Basin Seismic Traverses, Gravity (P198360), 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 Polda Basin Seismic Traverses, Gravity (P198360) contains a total of 220 point data values acquired at a spacing of 100 metres. The data is located in SA and were acquired in 1983, under project No. 198360 for Department of Mines and Energy South Australia (SADME).

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力扰动。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于地下岩石。经处理得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用要求。本次波达盆地重力地震测线数据集（Polda Basin Seismic Traverses, Gravity，P198360）共包含220个测点数据，测点间距为100米。该数据集采集于南澳大利亚（SA），采集时间为1983年，由南澳矿产与能源部（SADME）以项目编号198360立项实施。
