Diving Deeper Into Scuba Science

You will find in this book some valuable and reliable lessons about safe diving The editors of and authors of this book are a cadre of scientists and physicians with broad experience and knowledge of diving physiology and decompression theory. As is often the case, it requires a group effort to succeed in advancing practical knowledge. The colloquialism "the whole is greater than the sum of its parts" is often true and the PHYPODE Reasearch Group epitomizes this concept. By logically grouping the various elements of diving science and medicine with provocative "food for thought" sections, the text offers valuable lessons to those interested in the current state of diving. Despite nearly 170 years of reasearch, the fundamenal nature of decompression stress remains elusive. As is well outlined in this book, great advances have been made to the practical elements allowing for safe diving. Nonetheless, there are glaring voids of knowledge related to the nature of bubble nucleation, its consequences and methods to ameliorate risk. The synergy exhibited in this text not only provides a foundation for what is known, it offers a glimpse of where research is taking us. - Professor Stephen R. Thom, Dept. of Emergency Medicine, University of Maryland School of Medicine This is a book for all diving fans who want to discover their passion through a scientific approach. EXCERPT Decompression illnesses (DCI), or as they are called more scientifically: dysbaric disorders, represent a complex spectrum of pathophysiological conditions with a wide variety of signs and symptoms related to dissolved gas and its subsequent phase change.1, 2 Any significant organic or functional dysfunction in individuals who have recently been exposed to a reduction in environmental pressure (i.e., decompression) must be considered as possibly being caused by DCI until proven otherwise. However, apart from the more obvious acute manifestations of a single, sudden decompression, individuals who have experienced repetitive exposures (e.g. commercial or professional divers and active recreational divers) may also develop sub-acute or chronic manifestations, even if subtle and almost symptomless. ABOUT THE AUTHORS Dr. Costantino Balestra started to study neurophysiology of fatigue then started studies on environmental physiology issues. He teaches physiology, biostatistics, research methodology, as well as other subjects. He Is the Director of the Integrative Physiology Laboratory and a full time professor at the Haute Ecole Bruxelles-Brabant (Brussels). He is VP of DAN Europe for research and education, Immediate past President of the European Underwater and Baromedical Society. Peter Germonpré is the Medical Director of the Centre for Hyperbaric Oxygen Therapy of the Military Hospital Brussels, Belgium).

Our species is more profoundly connected to the sea than we ever realized, as an intrepid cadre of scientists, athletes, and explorers is now discovering. Deep follows these adventurers into the ocean to report on the latest findings about its wondrous biology -- and unimagined human abilities.

This text blends theoretical and scientific aspects with practical and directly applicable diving physiology and medical information. It is divided into three sections - the underwater environment, physiological responses to the underwater environment, and medical problems associated with the sport.

Diving Science...Revisited is like no other diving text, including its predecessor, Diving Science. Amplified with figures, tables, and photos in color, this book includes four unique and innovative parts amplified by nine contributors. - Medical problems of diving (MPD) are discussed from stimulus-response perspectives in the phase of a dive in which they are likely to occur. - MPD are explained by how they affect the human diver whether physical, physiological, psychological, and/or lack of awareness. - A variety of diving types and situations from breath-hold to rebreather, from children to women to older aged adults, from cold water to cave, and from deep altitude to diving with handicaps are described in individual chapters with their merits, hazards, and necessary precautions for safe diving. - Part IV contains a concise summary of the MPD from seven different perspectives ranging from the significance of the problem to when to return to diving. - Part V consists of a rhetorical question for each of the first four parts with bullet points that recap the subjects covered in each chapter. This book describes the positive as well as undesirable ways divers' interact with the aquatic environment. It is especially recommended for the following: -Diving instructors and supervisors - Those involved with clinical applications of hyperbaric oxygen therapy - Those engaged in diving-associated marine biology and underwater missions - All divers, whether novice or advanced, who want to advance their knowledge about the science and medical challenges of diving.

"The contents of From Snorkelers to Scuba Divers teachers as they respond to the recent attention on American students' performance in science relative to the rest of the world, as well as the many initiatives to improve the performance of students in the learning of science, focusing specifically on the K-5 classroom. The strategies presented throughout the text target specific science skills and concepts presented in the Next Generation Science Standards (NGSS). Skills and concepts vary from chapter to chapter to ensure each grade level and area within science (i.e., Earth and Space, Life, Physical Sciences) are represented. Furthermore, connections are made between the NGSS and Common Core Standards in both mathematics and literacy"--

From the author of the international Bestseller Breath Covering a diving championship in Greece on a hot and sticky assignment for Outside magazine, James Nestor discovered free diving. He had stumbled on one of the most extreme sports in existence: a quest to extend the frontiers of human experience, in which divers descend without breathing equipment, for hundreds of feet below the water, for minutes after they should have died from lack of oxygen. Sometimes they emerge unconscious, or bleeding from the nose and ears, and sometimes they don't come up at all. The free divers were Nestor's way into an exhilarating and dangerous world of deep-sea pioneers, underwater athletes, scientists, spear fishermen, billionaires and ordinary men and women who are poised on the brink of some amazing discoveries about the ocean. Soon he was visiting the scientists who live 60ft underwater (and are permanently high on nitrous dioxide), swimming with the notorious man-eating sharks of Réunion and descending thousands of feet in a homemade submarine. And on the way down, he learnt about the amazing amphibious reflexes activated in the human body under deep-water conditions, why dolphins were injected with LSD in an attempt to teach them to talk, and why sharks like AC/DC. The sea covers seventy per cent of Earth's surface, and still contains answers to questions about the world we are only beginning to ask: Deep blends science and adventure to uncover its amazing secrets.

This is the first book to span the depth between traditional sport diving editions and the complex medical/commercial texts. It provides a balanced view of the fascinations and hazards of deep diving through extensive factual development of its technical chapters.
