This book is about marine seismic sources, their history, their
physical principles and their deconvolution. It is particularly
accented towards the physical aspects rather than the mathematical
principles of signature generation in water as it is these aspects
which the authors have found to be somewhat neglected. A huge
amount of research has been carried out by both commercial and
academic institutions over the years and the resulting literature
is a little daunting, to say the least. In spite of this, the
subject is intrinsically very simple and relies on a very few
fundamental physical principles, a somewhat larger number of
heuristic principles and a refreshingly small amount of blunderbuss
mathematics. As such it is still one of those subjects in which the
gifted practical engineer reigns supreme and from which many of the
important advances have originated. In Chapter 1 of the book, the
underlying physics and concepts are discussed, including pressure
and wave propagation, bubble motion, virtual images and the factors
determining choice of source. In marine reflection seismology,
almost all of the seismic data acquired currently is done with
either the airgun or the watergun, which rely on the expulsion of
air and water respectively to generate acoustic energy. As a
consequence, the discussion in this chapter is geared towards these
two sources, as is much of the rest of the book.
