Geophysical Data Collection - ground gravity

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The gravity data collection contains both onshore and offshore data acquired on geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

重力数据（Gravity data）用于监测地球地下岩石密度变化所诱发的微小重力变动。本数据集收录了陆上与海上重力数据，其均由联邦、各州及北领地（NT）政府与私营机构开展的地球物理勘探采集获取。
