The Sydney Harbour Degaussing Range is situated opposite Bradley Head. The purpose of the survey was twofold. First, to determine the average normal values of the vertical (Z) and Horizontal (H) force components of the Earth's magnetic field in that part of the harbour which would be occupied by a ship passing over the coils. Secondly, to measure the magnetic elements, i.e. the Declination, Inclination and Horizontal Intensity of the Earth's field at a base station conveniently situated for use by naval personnel for the purpose of calibrating Pot Magnetometers, etc. The particulars of this survey work and given in this report.
