Stuart Shelf (P197858), 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 (P197858) contains a total of 135 point data values acquired at a spacing between 200 and 1000 metres. The data is located in SA and were acquired in 1978, under project No. 197858 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场变化。所采集的数据需通过标准流程进行处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，揭露地下的地质构造。经处理的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合预期使用要求。本次数据集所属的斯图尔特陆架（Stuart Shelf，编号P197858）共包含135组测点数据，测点间距介于200米至1000米之间。该数据集的采集区域位于南澳（SA），于1978年通过维多利亚州矿产与能源部（Department of Minerals and Energy (Victoria)）编号为197858的项目完成采集。
