NTGS Pedirka Gravity 202381 Spherical Cap Bouguer Anomaly SCBA267um

Gravity data measure 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 NTGS Pedirka Gravity 202381 Spherical Cap Bouguer Anomaly SCBA267um is a complete Bouguer anomaly grid for the NTGS Pedirka Gravity Survey (P202381) survey. This gravity survey was acquired under the project No. 202381 for the geological survey of NT. The grid has a cell size of 0.00944 degrees (approximately 1000m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 11443 gravity stations were acquired to produce this grid.

重力数据用于测量地球表面下方岩石密度变化引发的微小重力变动。所采集的数据将通过标准流程开展处理，以确保记录的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。处理后的数据会由GA地球物理学家进行质量核查，以保障GA发布的最终数据符合使用需求。本NTGS佩迪卡重力数据集202381号球冠布格异常（Spherical Cap Bouguer Anomaly, SCBA267um）是NTGS佩迪卡重力调查（P202381）项目对应的完整布格异常（Bouguer Anomaly）网格数据。本次重力调查依托编号为202381的项目开展，服务于北领地（NT）地质调查工作。该网格的单元尺寸为0.00944度（约合1000米）。数据单位为um/s²，又称重力单位，简称gu。本次网格数据共依托11443个重力测点采集生成。
