AbstractA three-component airborne magnetic survey of the Canadian Arctic was carried out in late 1970, at an average altitude of 3. 7 km, The survey data are in the form of averages over 30 seconds of tirne, or approximately 3.5 km of flight track. The international Geomagnetic Reference Field (IGRF) was removed from these data, and the resulting residuals plotted as profiles. A 3rd-degree polynomial was fitted to the survey data by least-squares to determine how well the IGRF represents the average regional field over the area. The polynomial was also used to obtain vector residuals.
