Aeromagnetic Surveys e-Book

Cover of e-BookA comprehensive introduction to the principles, practice and interpretation of aeromagnetic surveys was released in July 2009 as a service to the earth science community by Geosoft Inc. The work is a 150-page distillation of the many years' teaching experience of Earthworks' principal, Colin Reeves. The book has raised considerable interest and praise from reviewers and is downloadable as a PDF file, gratis.

Elsevier Geophysics Encyclopedia

Those seeking an introduction to the principles of aeromagnetic surveying may wish to refer to one of two geophysical encyclopedias that have been published in recent years with contributions from Earthworks.

In the eleven-volume Treatise on Geophysics (Gerald Schubert, ed) published by Elsevier (, Volume 5: Geomagnetism (Massaru Kono, ed) Chapter 5 contains 55 pages on Observation and Measurement Techniques by Turner, Rasson and Reeves. This, amongst other items, explains the principles of aeromagnetic surveying and the origins of magnetic anomalies in rocks.

Magnetic Anomaly Map of the World

The first compilation of magnetic anomalies worldwide was published in 2007. The efforts of decades by IAGA working groups were supported by Unesco and the Commission for the Geological Map of the World (CGMW) leading to the release of the first edition printed map, scale 1:50 000 000, at the XXIVth IUGG General Assembly in Perugia, Italy in July. The paper map may be ordered from the website below and the digital data is also available on request and may be viewed in Dapple or Google Earth. An account of the publication is given on the BBC website ( and a summary of the project is given in the January 2008 edition of The Leading Edge, p 32-33. A new edition of the map is scheduled for release at the Melbourne IUGG in 2011.
