East Arunta Gravity Bouguer Anomaly

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 East Arunta Gravity Bouguer Anomaly is a complete Bouguer anomaly grid for the East Arunta (P200680). This gravity survey was acquired under the project No. 200680 for the geological survey of NT. The grid has a cell size of 0.00376 degrees (approximately 400m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 5231 gravity stations were acquired to produce this grid.

重力数据用于测量因地球表面以下岩石密度变化而产生的重力微小变化。收集的数据通过标准方法处理，以确保记录的响应仅来源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以确保GA发布的最终数据符合预期用途。

东阿伦塔重力布格异常（East Arunta Gravity Bouguer Anomaly）是针对东阿伦塔（P200680）的完整布格异常（Bouguer anomaly）网格。该重力测量是在NT地质调查项目（编号200680）下开展的。网格的单元格大小为0.00376度（约400米）。数据单位为微米每二次方秒（um/s²），也称为“重力单位”（gravity units）或gu。共采集5231个重力测点以生成该网格。
