Atley Traverse (P200287), 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 Atley Traverse (P200287) contains a total of 90 point data values acquired at a spacing between 500 and 1000 metres. The data is located in WA and were acquired in 2002, under project No. 200287 for Geological Survey of Western Australia (GSWA).

重力数据用于监测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处理流程进行加工，以确保记录得到的重力响应仅由地下岩石引起。经处理得到的数据集可通过专业解译，用以揭示地下地质构造。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使用要求。
