Wood, F.W. & Everingham, I.B., 1953. A provisional isogonic map of Australia and New Guinea showing predicted values for the epoch 1955.5. Record  1953/033. Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Abstract

A provisional isogonic map of Australia and New Guinea has been prepared showing predicted values of declination for the middle of 1955. Along with this map, and isoporic chart is given showing the expected annual rate of change of declination over the same area for the same epoch. This rate of change (secular variation) can be taken as applying for all practical purposes from the beginning of 1953 to the end of 1957. It is expected that by the time a new map will have been prepared showing predicted values for 1960.5. The main points to note about the present map, in comparison with that for 1950.5 are: i) that the declination over Tasmania is from two-thirds to three-quarters of a degree greater (i.e. more easterly) than would have been expected from the 1950.5 map; ii) the annual rate of change of declination over the south-eastern part of Australia shows an increase in positive (i.e. easterly) value; iii) the annual rate of change of declination over the north-western part of the mainland now shows a small negative (i.e. westerly) value instead of the small positive value shown in previous years.
