Since the first edition of this book, there have been rapid and significant advances made in the instruments and systems of offshore surveying with automated data handling now generally the rule. In addition, the surveyor's area of work has changed. With the rapid development of oil field exploration, the surveyor is becoming increasingly concerned with pipelaying, production platform installation and seismic aspects. This new edition contains considerable revisions and new material which reflect recent advances in the instrument and systems of offshore surveying and the rapid development of oil field exploration.

This textbook provides a thorough introduction to the subject of sea surveying. The third edition has been revised to provide a unified approach to geodesy and the physical attributes of water, earth and air, explaining their effects on sensors and signals, and the methods of presenting variable data in a common relationship. Positioning systems occupy a major part of the book and new text has been added on these as well as on laser and swathe sounding units. Further information has also been added on offshore operations and on survey work for coastal management
