NTGS Brunette Downs Gravity Survey, 2021, P202180

The NTGS Brunette Downs Gravity Survey, 2021, is a survey funded by the Northern Territory (NTGS) and managed by Geoscience Australia (GA). Atlas Geophysics was commissioned by GA to conduct the survey. The survey was conducted as part of NTGS’s Resourcing the Territory initiative and was given a survey ID of 202180. The survey is a roughly east-west rectangular shape covering approximately 57,000 square kilometres. It consists of a 2km by 2km grid across the entire survey area, in some areas omitting existing 4km by 4km gravity stations, and several areas of infill at 1km by 1km and 500m by 500m. The survey covers approximately 57,000 square kilometres, to the north and east of Tennant Creek to the border with Queensland. This survey acts as infill for other surveys: 200980 “Barkly”, 201580 “Northern Wiso Basin” and 201701 “Southern Nicholson”, which were acquired in regional 4km x 4km grid configurations.The data package consist of 17,312 gravity stations as a point located dataset, a series of grids in GDA94 Geodetic at 500m equivalent cells size, and the Operations Report.
