Contract Helicopter Gravity (P196612), 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 Contract Helicopter Gravity (P196612) contains a total of 818 point data values acquired at a spacing between 4000 and 10000 metres. The data is located in QLD and were acquired in 1966, under project No. 196612 for None.重力数据用于表征地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准流程进行处理，以确保记录得到的响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，揭示地下地质构造特征。处理后的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合使用要求。本合同航空重力数据集（Contract Helicopter Gravity，编号P196612）共包含818个测点数据，测点间距介于4000米至10000米之间。该数据集采集于昆士兰州（QLD），于1966年依托编号为196612的项目完成采集，委托方信息未注明。
