Alsk Detailed Gravity Survey, NT. (P199226), 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 Alsk Detailed Gravity Survey, NT. (P199226) contains a total of 1575 point data values acquired at a spacing between 25 and 100 metres. The data is located in NT and were acquired in 1992, under project No. 199226 for None.

重力数据用于量化地球表层下方岩石密度变化所引发的微小重力场扰动。所采集的重力数据将通过标准化流程进行预处理，以确保记录得到的响应仅源自地下岩石的重力贡献。经处理后得到的数据集可通过地质解译揭示地下地质构造。预处理完成的数据将由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实际应用需求。
