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.

重力数据用于量化地球表层下方岩石密度变化所引发的微小重力场变化。所采集的重力数据将通过标准化流程开展处理，以确保记录的响应仅源于地下岩石的密度效应。经处理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审核，以确保GA发布的最终数据符合应用要求。本次的北领地地质调查局（Northern Territory Geological Survey, NTGS）Pedirka重力202381球冠布格异常（Spherical Cap Bouguer Anomaly, SCBA267um）数据集，是NTGS开展的Pedirka重力调查（P202381）的完整布格异常（Bouguer Anomaly）网格数据。本次重力调查是为北领地（NT）地质调查项目编号202381所实施的。该网格的单元尺寸为0.00944度（约合1000米）。数据单位为um/s²，亦称为重力单位（gravity units），缩写为gu。本次网格数据的采集共覆盖11443个重力测点。
