West Musgrave Complete Gravity Bouguer Anomaly Grid geodetic

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 West Musgrave Complete Gravity Bouguer Anomaly Grid geodetic is a complete Bouguer anomaly grid for the West Musgrave Gravity 2008 WA (P200860). This gravity survey was acquired under the project No. 200860 for the geological survey of WA. The grid has a cell size of 0.0046 degrees (approximately 485m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 4027 gravity stations were acquired to produce this grid.

重力数据用于测量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，以确保记录的响应仅源自地下岩石的影响。处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用要求。
本次的西马斯格雷夫完整重力布格重力异常（Bouguer Anomaly）大地测量网格，是针对2008年西澳大利亚州西马斯格雷夫重力勘探项目（P200860）的完整布格异常网格。
本次重力勘探是为开展西澳大利亚州地质调查，于编号200860的项目框架下实施的。
该网格的单元格尺寸为0.0046度（约合485米）。
数据以微米每二次方秒（μm/s²）为单位，该单位也被称为重力单位（gravity units，简称gu）。
为生成该网格，共采集了4027个重力测点。
