While the effects of pressure change are readily quantified in physics, chemistry, and engineering applications, the physiology, medicine, and biology of pressure changes in living systems are much more complicated. This complex science translated to technical diving is discussed in a five-part series, with each topic self-contained and strategically developed in relationship to diving, spanning many disciplines and focusing on a number of technical areas. A suite of application exercises is provided at strategic points in the text. Additional material focusing on diving data, statistical correlations, underwater tests, and risk is included.

The biophysics of diving and decompression in the human body are complex. The average individual experiences atmospheric pressure swings of 3% at sea level and over 20% at altitudes greater than a mile. Divers and their equipment can experience compressions and decompressions in orders of greater magnitude than pressures outside water, all within considerably shorter time spans. The understanding of the mechanics behind diving is based on absolute pressure and pressure changes. While these mechanics are readily quantified in physics, chemistry, and engineering applications, the physiological and medical aspects of pressure changes in living systems need to be understood clearly to assess the safety of routine divers. This monograph is a compilation of a body of knowledge on biophysics, gas transport, bubble studies and physiological models used for diving and hyperbaric applications. Information in the monograph is divided into three parts that cover biophysics and models, data correlation and validation approaches and practical applications, respectively. The book is a useful resource for researchers and maritime professionals who wish to understand the biophysics behind underwater diving and decompression for the purpose of maritime operations as well as diving simulation applications.

As we move into the 1980s, there is an increasing awareness that our civilization is going through a profound cultural transformation. At the heart of this transformation lies what is often called a "paradigm shift"-a dramatic change in the thoughts, perceptions, and values which form a particular vision of reality. The paradigm that is now shifting comprises a large number of ideas and values that have dominated our society for several hundred years; values that have been associated with various streams of Western culture, among them the Scientific Revolution of the seventeenth century, The Enlightenment, and the Industrial Revolution. They include the belief in the scientific method as the only valid approach to knowledge, the split between mind and matter, the view of nature as a mechanical system, the view of life in society as a competitive struggle for survival, and the belief in unlimited material progress to be achieved through economic and technological growth. All these ideas and values are now found to be severely limited and in need of radical revision.

This book began life as a series of lectures given to second andthird year undergraduates at Oxford University. Theselectures were designed to give students insights as to how marineecosystems functioned, how they were being affected by natural andhuman interventions, and how we might be able to conserve them andmanage them sustainably for the good of people, both recreationallyand economically. This book presents 10 chapters, beginningwith principles of oceanography important to ecology, throughdiscussions of the magnitude of marine biodiversity and the factorsinfluencing it, the functioning of marine ecosystems at withintrophic levels such as primary production, competition anddispersal, to different trophic level interactions such asherbivory, predation and parasitism. The final three chapterslook at the more applied aspects of marine ecology, discussionfisheries, human impacts, and management and conservation. Other textbooks covering similar topics tend to treat the topicsfrom the point of view of separate ecosystems, with chapters onreefs, rocks and deep sea. This book however is topic drivenas described above, and each chapter makes full use of examplesfrom all appropriate marine ecosystems. The book is illustratedthroughout with many full colour diagrams and high qualityphotographs. The book is aimed at undergraduate and graduate students atcolleges and universities, and it is hoped that the many examplesfrom all over the world will provide global relevance andinterest. Both authors have long experience of research and teaching inmarine ecology. Martin Speight’s first degree was inmarine zoology at UCNW Bangor, and he has taught marine ecology andconservation at Oxford for 25 years. His research studentsstudy tropical marine ecology from the Caribbean through EastAfrica to the Far East. Peter Henderson is a Senior ResearchAssociate at the University of Oxford, and is Director of PiscesConservation in the UK. He has worked on marine andfreshwater fisheries, as well as ecological and economic impactsand exploitation of the sea in North and South America as well asEurope.

The evidence discovered at underwater crime scenes must be handled with the same attention to proper chain of custody procedures as with any other type of investigation. Improper handling of these scenes can lead to evidence being lost, unrecognizable, destroyed, contaminated, or rendered inadmissible at the time of trial. Updated and expanded, Underwater Forensic Investigation, Second Edition presents a comprehensive approach to the processing of an underwater crime scene and the steps necessary to conduct the operation. The book summarizes the history, physics, and laws applicable to underwater investigations and includes topics such as team formation, roles, deployment, and accountability. Explaining procedures that can make a true difference in the final outcome of water-related incidents, the author also debunks myths associated with submerged evidence. This second edition contains several new chapters on photography, contaminated sites, preservation of evidence, and release of the crime scene, and includes expanded information on death investigation and organizing the dive team. Nearly 100 color illustrations supplement the text. The science of water-related investigations is still in its infancy, and hence, the field needs accurate and useful sources of education. This text will assist law enforcement professionals and those in other areas of public safety in gaining the knowledge that has historically been lacking. The incorporation of the procedures presented will enable those tasked with working these scenes to develop a greater degree of professionalism, objectivity, thoroughness, and accuracy relating to the investigation of water-related incidents—increasing the chance for successful resolution of these difficult cases.
