Lake Fowler Seismic, Magnetic, Gravity, Seismic Refraction Survey (P196944), 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 Lake Fowler Seismic, Magnetic, Gravity, Seismic Refraction Survey (P196944) contains a total of 1255 point data values acquired at a spacing between 200 and 800 metres. The data is located in SA and were acquired in 1969, under project No. 196944 for Beach Energy Ltd.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。所采集的原始数据将通过标准流程开展处理，以确保记录得到的响应仅源自地下岩石。经处理得到的数据集可通过地质解译，揭示地下地质构造特征。处理完成的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据符合使用需求。本次福勒湖（Lake Fowler）地震、磁法、重力及地震折射调查（项目编号：P196944）共包含1255个测点数据，测点间距介于200米至800米之间。本次调查数据采集于南澳大利亚州（SA），该调查于1969年受Beach Energy Ltd.委托，以项目编号196944实施完成。
