Nulla Nulla Gravity (P196554), 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 Nulla Nulla Gravity (P196554) contains a total of 21 point data values acquired at a spacing of 362 metres. The data is located in NSW, SA and were acquired in 1965, under project No. 196554 for Department of Mines and Energy South Australia (SADME).

重力数据用于测量因地球表面下岩石密度变化而产生的重力微小变化。采集的数据通过标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。GA地球物理学家会对处理后的数据进行质量检查，确保GA发布的最终数据符合预期用途。
这个Nulla Nulla重力数据集（P196554）包含21个点数据值，点间距为362米。数据位于新南威尔士州（NSW）和南澳大利亚州（SA），于1965年采集，属于南澳大利亚矿产与能源部（SADME）的196554号项目。
