South Gippsland 2D Seismic Gravity Traverese (P201530), 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 South Gippsland 2D Seismic Gravity Traverese (P201530) contains a total of 529 point data values acquired at a spacing between 90 and 435 metres. The data is located in VIC and were acquired in 2015, under project No. 201530 for Geoscience Australia.

重力数据用于测量地球表层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，以确保记录得到的响应仅源于地下岩石的影响。经处理后得到的数据集可通过解译，用以揭示地下地质构造。经处理后的数据将由澳大利亚地质调查局（Geoscience Australia, GA）的地球物理学家开展质量核查，以确保该局发布的最终数据符合使用要求。本次发布的南吉普斯兰二维地震重力测线（2D Seismic Gravity Traverse, P201530）共包含529个测点数据，测点间距介于90米至435米之间。该数据集采集于维多利亚州（Victoria, VIC），采集时间为2015年，隶属于澳大利亚地质调查局编号为201530的项目。
