Stuart Shelf (P198077), 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 Stuart Shelf (P198077) contains a total of 200 point data values acquired at a spacing between 500 and 6000 metres. The data is located in SA and were acquired in 1980, under project No. 198077 for Department of Minerals and Energy (Victoria).

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由地下岩石产生。经处理所得的数据集可通过解译，用以揭示地下地质构造。GA地球物理学家会对经处理的数据开展质量校验，以确保GA发布的最终数据符合使用要求。本次斯特尔特陆架（Stuart Shelf，P198077）数据集总计包含200个测点数据，测点间距介于500米至6000米之间。该数据采集区域位于南澳大利亚州（SA），采集工作于1980年完成，隶属于维多利亚州矿产与能源部198077号项目。
