Well done Anew guide file with a straightforward descriptionto the GA geophysics team!Geoscience Australias James Goodwin has assembled the advice of 40 years of publications and AGSO turned GAs surveying experience into an Airborne Magnetic and Radiometric Technical Standards guide. This 57-page tome is a welcome source of tried-and-true data collection practices and processing methods. While aimed at those tendering with GA and the state surveys, we hope explorers will adopt relevant recommendations.This publication helps to address several issues that the ASEG Technical Standards Committee is facing regarding formats, methods and survey types, and as such the ASEG will direct explorers and surveyors to this reference for clarity.CalibrationAcceptable calibration and test runs for the various instruments described set out what constitutes a well prepared, reliable survey instrument, and the compensations required for using it in an aircraft. Encouraging the inclusion of calibration and test runs records with the final data will instil greater confidence in geophysicists stitching surveys.Magnetic gradiometryA recent issue for the ASEG Technical Standards Committee has been the lack of local magnetic gradiometry surveys, which are apparently common overseas.
