Apsley Region Gravity (P196950), 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 Apsley Region Gravity (P196950) contains a total of 257 point data values acquired at a spacing between 250 and 700 metres. The data is located in TAS and were acquired in 1969, under project No. 196950 for University of Tasmania.

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变化。所采集的数据将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示地下地质构造。GA地球物理学家将对处理后的数据开展质量核查，以确保GA发布的最终数据符合使用要求。
本次发布的阿普利地区重力数据集（编号P196950）共包含257个测点数据，测点间距介于250米至700米之间。该数据集的采集区域位于塔斯马尼亚州（TAS），采集工作于1969年完成，隶属于塔斯马尼亚大学编号为196950的科研项目。
