Georgina Basin Seismic Traverses, 1989, NT PR1991-0009 (P199189), 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 Georgina Basin Seismic Traverses, 1989, NT PR1991-0009 (P199189) contains a total of 1052 point data values acquired at a spacing between 190 and 5000 metres. The data is located in NT and were acquired in 1989, under project No. 199189 for Pacific Oil and Gas Pty Ltd.

重力数据用于测量地球表层下方岩石密度变化引发的微小重力场变化。所采集的数据将通过标准化方法进行处理，以确保记录得到的响应仅由地下岩石的密度变化所导致。经处理得到的数据集可通过解译，用以揭示地下地质构造。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发布的最终数据符合使用要求。本数据集为1989年北领地（Northern Territory，简称NT）乔治娜盆地地震测线数据（编号NT PR1991-0009 (P199189)），共包含1052个测点数据，测点间距介于190米至5000米之间。该数据采集点位位于北领地，采集时间为1989年，所属项目编号为199189，服务于太平洋石油天然气私人有限公司（Pacific Oil and Gas Pty Ltd）。
