Eyre Peninsula South Seismic Traverses, Gravity (P197561), 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 Eyre Peninsula South Seismic Traverses, Gravity (P197561) contains a total of 116 point data values acquired at a spacing of 125 metres. The data is located in SA and were acquired in 1975, under project No. 197561 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引发的微小重力场变化。所采集的数据将通过标准流程开展处理，以确保记录得到的响应仅源于地下岩石的影响。经处理后生成的数据集可通过解译，揭示地下地质构造特征。GA地球物理学家将对处理后的数据进行质量核查，以确保GA发布的最终数据符合使用要求。本次发布的艾尔半岛南部地震测线与重力数据集（P197561）共包含116个测点数据，测点采集间距为125米。该数据集采集于南澳大利亚州（South Australia, SA），采集工作于1975年实施，隶属于南澳大利亚矿产与能源部（Department of Mines and Energy South Australia, SADME）编号为197561的项目。
