Stuart Shelf (P197978), 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 (P197978) contains a total of 789 point data values acquired at a spacing between 100 and 500 metres. The data is located in SA and were acquired in 1979, under project No. 197978 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，以确保记录得到的响应仅由地下岩石的密度变化产生。经处理后的数据集可通过地质解译揭示地下地质构造。经处理的数据会由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需求。本数据集为斯图尔特陆架（Stuart Shelf，编号P197978）相关数据，共包含789个测点数据，测点间距介于100米至500米之间。该数据采集区域位于南澳大利亚（South Australia，简称SA），采集工作于1979年完成，隶属于维多利亚州矿产与能源部（Department of Minerals and Energy, Victoria）编号为197978的项目。
