Woomera Prohibited Area Gravity Survey p201350 Spherical Cap Bouguer

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 Woomera Prohibited Area Gravity Survey p201350 Spherical Cap Bouguer is a complete Bouguer anomaly grid for the Woomera Prohibited Area Gravity Survey, 2013 (P201350) survey. This gravity survey was acquired under the project No. 201350 for the geological survey of SA. The grid has a cell size of 0.00385 degrees (approximately 399m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 34702 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。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发布的最终数据满足使用需求。
本数据集为伍默拉禁区重力测量（P201350）球面帽布格（Spherical Cap Bouguer）数据集，是2013年伍默拉禁区重力测量（P201350）项目的完整布格异常（Bouguer anomaly）网格。本次重力测量为南澳大利亚州（South Australia，简称SA）地质调查工作的201350号项目作业内容。该网格的单元尺寸为0.00385度（约399米）。数据单位为微米每二次方秒（um/s²），亦称为“重力单位”（gravity units，简称gu）。为生成该网格，本次测量共获取了34702个重力测点数据。
