Sander Geophysics Limited (SGL) conducted a fixed-wing high resolution airborne gravimetric survey over two survey blocks, Pilbara Northwest and Pilbara Southeast in Northwestern Australia for Geoscience Australia and its partner the Geological Survey of Western Australia (GSWA). The traverse lines were oriented east-west in the Pilbara Northwest block and north-south in the Pilbara Southeast block and spaced at 2500 m. A limited number of control lines flown exclusively in the Pilbara Northwest block were oriented north-south and spaced at 50,000 m. A drape surface was created taking into account the terrain and the performance of the aircraft at the expected altitudes and estimated temperatures. The survey was flown with a target clearance of survey 160m above ground level.   Survey details Survey Name: Pilbara WA airborne gravity surveys 2019 State/Territory: Western Australia (WA) Datasets Acquired: Airborne gravity Geoscience Australia Project Number: P1314 Acquisition Start Date: April 23, 2019 Acquisition End Date: June 16, 2019 Flight line spacing: 2500m Flight line direction: 270deg / EW (Pilbara NW); 180deg / NS (Pilbara SE) Control line spacing: 50,000m – Pilbara NW only Control line direction: 180 deg / NS – Pilbara NW only Total line kilometers: 69,943 Nominal terrain clearance (above ground level): 160m Aircraft type: Cessna Grand Caravan 208B Data Acquisition: Sander Geophysics Limited Project Management: Geoscience Australia Quality Control: Geoscience Australia Dataset Ownership: GSWA and Geoscience Australia   This data package release contains the final survey deliverables received from the contractor SGL, and peer reviewed by Dr Mark Dransfield.   1.
