Several excellent text books exist which cover the subject of Applied Geophysics but the degree of specialisation and sophistication of present geophysical techniques inevitably means that they have insufficient detail to be used other than as a general introduction. GA intends to provide a series of monographs with sufficient detail to be of use to the practising geophysicist and with sufficient discussion of the scientific fundamentals to be suitable for the student and the research worker.

Essentially, the monographs will be critical reviews of the aims, methods and status of the various techniques covering the whole range of instrumentation, operation and interpretation. They will each be written by a practising geophysicist of considerable experience. The monographs will appeal to advanced students in geoexploration at Universities and Technological Universities as well as to geophysicists and others engaged in geophysical exploration.

The author of this monograph is to be included among the most eminent geophysicists of our age. He merits this consideration as much for his inventive genius as for his energy and tenaceous will to carry the development of his ideas to the point of efficient application. He combines insight and mathematical reason to the end that he has an exceptionally clear understanding of the nature of the geophysical measurements upon which we operate. Moreover, unlike so many respectable theoreticians, he is never satisfied to present the solution of a problem on page after page of formulas spiced with mathematical symbols; he always explains it in terms of practical application including numerical examples and computer programs which he writes himself. This book is dedicated essentially to the functional transformations of gravity and magnetic anomalies. The first chapters present a general elementary view of potentials and the fields which are derived from potentials. We also discuss the principal properties of harmonic functions useful in geophysics. In the following two chapters, these principles are specialized for use in applied geophysics.
