Dalhousie Gravity 1963D9 (P196340), 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 Dalhousie Gravity 1963D9 (P196340) contains a total of 2207 point data values acquired at a spacing of 6436 metres. The data is located in SA and were acquired in 1963, under project No. 196340 for French Petroleum Co.

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场扰动。所采集的原始数据将通过标准化处理流程进行校正，以确保记录得到的重力响应仅源于地下岩石的影响。经处理后的数据集可通过地质解译，用以揭示地下地质构造。该处理后的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合应用要求。本达尔豪西1963D9重力数据集（编号P196340）共计包含2207个测点数据，测点间距为6436米。该数据集的采集点位位于SA区域，采集工作于1963年完成，所属项目编号为196340，服务于法国石油公司（French Petroleum Co.）。
