Esperance Gravity Survey 2013 (P201361), gravity point data

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 Esperance Gravity Survey 2013 (P201361) contains a total of 7892 point data values acquired at a spacing between 1000 and 2500 metres. The data is located in WA and were acquired in 2013, under project No. 201361 for Geological Survey of Western Australia (GSWA).

重力数据可测量因地球表层下方岩石密度变化引发的微小重力变化。所采集的数据均通过标准方法处理，以确保记录得到的重力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，揭示地下地质构造特征。经处理的数据需由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用需求。本2013年埃斯佩兰斯重力测量项目（编号P201361）共包含7892个测点数据，测点间距介于1000米至2500米之间。该数据集的测点分布于西澳大利亚州（WA），采集工作于2013年开展，隶属于西澳大利亚地质调查局（Geological Survey of Western Australia, GSWA）编号为201361的项目。
