The National Oceanic and Atmospheric Administration (NOAA) Diving Program, which is recognized as one of the leading authorities on scientific diving and undersea technology has released the Fourth Edition of the NOAA Diving Manual. This manual was last published in 1991, with over 25,000 books sold within six years. The newly revised manual is published in full color, with 668 coated pages. it contains basic through advanced applied diving technologies and is written in a non-technical style so it will be informative to all who are interested in safe diving. This completely revised Fourth Edition is one of the most detailed diving reference books available and is a valuable resource to all who are interested in a complete encyclopedia of diving technology, equipment, techniques, and procedures. More than 100 authors and reviewers, selected from a diverse spectrum of experts in recreational, commercial, military, scientific, and research diving, combined their expertise to address the complex issues involved in today's diving. This new edition contains twenty-one chapters on all aspects of diving: techniques to improve the methodology of underwater scientific research, new gear, operational techniques, and details to help the diver dive safely. In addition, there are ten appendices, including a glossary, references, and a detailed index. The technologies of rebreathers and mixed gas diving, including nitrox and oxygen are included; diving physics, physiology, decompression, and diving medicine have also been updated to reflect recent developments in the diving industry. The NOAA Nitrox Tables and the Nitrox Diving Procedures allow deeper and/or longer bottom times to increase diver efficiency when using nitrox, without affecting safety or increasing decompression time.
