AN elementary textbook is much concerned with the fundamentals of a subject and these do not change with time. In this respect the second edition of our book •has been little modified. In every other it is much altered for the subject has advanced greatly since we gathered together the material for the original version. The changes have been brought about mainly by developments in …

In conventional utilization of the seismic reflection method, it has traditionally been assumed that seismic signals can be viewed as a band-limited normal incidence reflection coefficient series with appropriate traveltime and amplitude variation due to propagation through an overburden. Ostrander (1982) demon strated that gas sand reflec…
The idea for this book originated in 1987 while I was preparing for lectures on courses in applied geology and environmental geo• physics at Plymouth Polytechnic (now the University of Plymouth), Devon, England. Students who had only very basic mathematical skills and little if any physics background found most of the so• called 'introductory' texts difficult to follow owing to…
The magnetotelluric method is one of many methods based on measuring the electrical resistivity of the subsurface as an indirect means for studying geology, but it is a method that caught the imagination of many explorations when it was first described nearly three decades ago by Cagniard and Tikhonov.
