Great Barrier Reef, Adjacent Coast, North Qld, 1954-1960 (P195401), 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 Great Barrier Reef, Adjacent Coast, North Qld, 1954-1960 (P195401) contains a total of 38 point data values acquired at a spacing of 5000 metres. The data is located in NSW, QLD and were acquired in 1954, under project No. 195401 for Great Barrier Reef Committee.

重力数据用于探测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化流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理后得到的数据集可通过解译，揭示地下地质构造特征。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发布的最终数据符合使用要求。本数据集为1954年至1960年昆士兰州北部大堡礁及邻近海岸的重力数据（项目编号P195401），共包含38个测点数据，测点间距为5000米。该数据采集于1954年，由大堡礁委员会牵头的编号为195401的项目所获取，采集区域涵盖新南威尔士州（NSW）与昆士兰州（QLD）。
