Ocean Acidification


Book Description

The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.




Nutritional Needs in Cold and High-Altitude Environments


Book Description

This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.




Cold-Water Corals


Book Description

There are more coral species in deep, cold-waters than in tropical coral reefs. This broad-ranging treatment is the first to synthesise current understanding of all types of cold-water coral, covering their ecology, biology, palaeontology and geology. Beginning with a history of research in the field, the authors describe the approaches needed to study corals in the deep sea. They consider coral habitats created by stony scleractinian as well as octocoral species. The importance of corals as long-lived geological structures and palaeoclimate archives is discussed, in addition to ways in which they can be conserved. Topic boxes explain unfamiliar concepts, and case studies summarize significant studies, coral habitats or particular conservation measures. Written for professionals and students of marine science, this text is enhanced by an extensive glossary, online resources, and a unique collection of color photographs and illustrations of corals and the habitats they form.




Cold Ocean Physiology


Book Description

From a human viewpoint, the cold waters of deep sea and polar marine regions present an inhospitable and harsh environment for life. The study of organisms that have exploited this seemingly hostile ecological niche has revealed intriguing physiological adaptations. This volume summarizes the most recent information on the adaptations exhibited by representatives of the main groups of polar animals, including marine invertebrates, fish, mammals, and birds. The scales of adaptation range from the whole organism to the underlying molecular mechanisms. Unique in its breadth of coverage, this volume will provide an important resource for all those concerned specifically with how animals have adapted to life in extreme conditions.




Exercise Physiology


Book Description

Thoroughly updated with all the most recent findings, this Seventh Edition guides you to the latest understanding of nutrition, energy transfer, and exercise training and their relationship to human performance. This new edition continues to provide excellent coverage of exercise physiology, uniting the topics of energy expenditure and capacity, molecular biology, physical conditioning, sports nutrition, body composition, weight control, and more. The updated full-color art program adds visual appeal and improves understanding of key topics. A companion website includes over 30 animations of key exercise physiology concepts; the full text online; a quiz bank; references; appendices; information about microscope technologies; a timeline of notable events in genetics; a list of Nobel Prizes in research related to cell and molecular biology; the scientific contributions of thirteen outstanding female scientists; an image bank; a Brownstone test generator; PowerPoint(R) lecture outlines; and image-only PowerPoint(R) slides.







Handbook of Offshore Helicopter Transport Safety


Book Description

Handbook of Offshore Helicopter Transport Safety: Essentials of Underwater Egress and Survival provides a comprehensive look at the issues and concerns facing offshore helicopter transport. The book offers guidance for offshore helicopter operators, survival instructors, and the global offshore workforce, including discussions of safety management systems, safety briefings, survival equipment, underwater egress training, water impact/ditching statistics, and search and rescue. Each area of interest details pertinent information spanning approximately 30 years of offshore operations. Early sections discuss helicopter transport safety, safety regulations, and standards, while subsequent chapters cover Helicopter Underwater Escape Training (HUET) programs and their development and training, followed by final chapters on the effects of HUET, Emergency Breathing Systems (EBS), and Helicopter Transportation Suit (HTS). - Presents Helicopter Underwater Escape Training (HUET), requirements for physical fidelity, contextual interference, and retention of skills - Details the current understanding of breath-holding and cardiac response in cold environments - Discusses stress, executive functioning, and performance in extreme situations - Covers current standards of emergency breathing systems and next to skin clothing following egress from a ditched helicopter in cold water - Includes the most up-to-date water impact/ditching statistics with a focus on human tolerances and survivability




Marine Mammal Physiology


Book Description

Suppose you were designing a marine mammal. What would you need to think about to allow it to live in the ocean? How would you keep it warm? What would you design to allow it to dive for very long periods to extreme depths? Where would it find water to drink? How would you minimize the cost of swimming, and how would it find its prey in the deep an




Mediterranean Cold-Water Corals: Past, Present and Future


Book Description

What do we know about Mediterranean Cold (Deep)-Water coral ecosystems? In this book, specialists offer answers and insights with a series of chapters and short papers about the paleoecology, biology, physiology and ecology of the corals and other organisms that comprise these ecosystems. Structured on a temporal axis—Past, Present and Future—the reviews and selected study cases cover the cold and deep coral habitats known to date in the Mediterranean Basin. This book illustrates and explains the deep Mediterranean coral habitats that might have originated similar thriving ecosystems in today’s Atlantic Ocean.




Diving Physiology of Marine Mammals and Seabirds


Book Description

Analysing the physiological adaptations of marine mammals and seabirds, this book provides a comprehensive overview of what allows these species to overcome the challenges of diving to depth on a single breath of air. Through comparative reviews of texts on diving physiology and behaviour from the last seventy-five years, Ponganis combines this research into one succinct volume. Investigating the diving performance of marine mammals and seabirds, this book illustrates how physiological processes to extreme hypoxia and pressure are relevant to the advancement of our understanding of basic cellular processes and human pathologies. This book underscores the biomedical and ecological relevance of the anatomical, physiological and molecular/biophysical adaptations of these animals to enable further research in this area. An important resource for students and researchers, this text not only provides an essential overview of recent research in the field, but will stimulate further research into the behaviour and physiology of diving.
