Book Description
Well–travelled divers all acknowledge that the best diving in the world is found in the warm waters of tropical Bali. Bali is located in the famous "coral triangle," the center of the world's tropical marine diversity, and the island is blessed with a stunning variety of dive sites—shipwrecks, quiet black sand bays, crystalline hard coral reefs over bright white sand, lava ridges draped in gorgonians and soft coral, and current–swept pinnacles, swirling with fish. Diving Bali is a comprehensive diving guide covering all of Bali and it's surrounding reefs. It presents in great detail some of the best dive sites in the tropical western Pacific. Our seasoned diver–authors have an aggregate half–century of experience exploring these waters, and each site receives thorough coverage, including detailed maps, color photos, and a full description of access, conditions, and facilities. This Bali diving guide features: Practicalities: Detailed travel information for every budget, including accommodations, transportation, prices, seasons, and dive operators. Information: Local history, diving lore, site conditions, and more than 50 maps. Photography: More than 100 color photographs by top photographers.

Book Description
Breath-hold diving marine mammals are able to remain submerged for prolonged periods of time and dive to phenomenal depths while foraging. A number of physiological, biochemical and behavioral traits have been suggested that enable this life style, including the diving response, lung collapse, increased O2 stores, diving induced hypometabolism, and stroke-and-glide behavior to reduce dive metabolic cost. Since the initial studies by Scholander in the 1940‘s, when most of the physiological and biochemical traits were suggested, few have received as much study as the diving response and O2 management. The calculated aerobic dive limit (cADL) was an important concept which allowed calculation of the aerobic dive duration, and was defined as the total O2 stores divided by the rate of O2 consumption (metabolic rate). The total O2 stores have been defined for several species, and studies in both forced and freely diving animals have refined the metabolic cost of diving. Currently there appears to be little consensus about whether marine mammals perform a significant proportion of dives exceeding the cADL or not and there may be large differences between species. The diving response is a conserved physiological trait believed to arise from natural selection. The response includes diving-induced bradycardia, peripheral vasoconstriction, and altered blood flow distribution. While the response results in reduced cardiac work, it is not clear whether this is required to reduce the overall metabolic rate. An alternate hypothesis is that the primary role of the diving bradycardia is to regulate the degree of hypoxia in skeletal muscle so that blood and muscle O2 stores can be used more efficiently. Scholander suggested that the respiratory anatomy of marine mammals resulted in alveolar collapse at shallow depths (lung collapse), thereby limiting gas exchange. This trait would limit uptake of N2 and thereby reduce the risk of inert gas bubble formation and decompression sickness. In his initial treatise, Scholander suggested that alveolar collapse probably made inert gas bubble formation unlikely during a single dive, but that repeated dives could result in significant accumulation that could be risky. Despite this, lung collapse has been quoted as the main adaptation by which marine mammals reduce N2 levels and inert gas bubble formation. It was surprising, therefore, when recent necropsy reports from mass stranded whales indicated DCS like symptoms. More recent studies have shown that live marine mammals appear to experience bubbles under certain circumstances. These results raise some interesting questions. For example, are marine mammals ever at risk of DCS, and if so could N2 accumulation limit dive performance? While an impressive number of studies have provided a theoretical framework that explains the mechanistic basis of the diving response, and O2 management, many questions remain, some widely-accepted ideas actually lack sufficient experimental confirmation, and a variety of marine mammal species, potentially novel models for elucidating new diving adaptations, are understudied. The aim of this Frontiers Topic is to provide a synthesis of the current knowledge about the physiological responses of marine mammals that underlie their varied dive behavior. We also include novel contributions that challenge current ideas and that probe new hypotheses, utilize new experimental approaches, and explore new model species. We show that the field has recently entered a phase of renewed discovery that is not only unraveling more secrets of the natural diving response but will drive new applications to aid human exploration of the ocean depths. We also welcome comparative analyses, especially contributions that compare marine mammals with human divers.

Book Description
SCUBA in Cuba? Find seashells in the Seychelles? Discover the must-dive destinations recommended by the experts—includes beautiful underwater photos. The earth’s oceans hold many wondrous surprises—be they the small, colorful critters off the coast of Papua New Guinea, opportunistic red demon squids in the Sea of Cortes, or naval wrecks in the lagoon of Bikini Atoll. In Fifty Places to Dive Before You Die, Chris Santella has invited diving experts from around the world to share some of their favorite destinations, so ardent divers can experience these underwater wonders for themselves—either on location in their SCUBA gear, or at home in their armchair. Part of the bestselling Fifty Places series, the book takes divers from hot-spot destinations like Raja Ampat (off the coast of West Guinea) to old Caribbean favorites like Grand Cayman. Swim among whale sharks off Myanmar, befriend wolf eels off the coast of Maine, and marvel at the giant mola mola of Lembognan, Indonesia. These wonderful creatures—plus the brilliant coral reefs that often provide their backdrop—are captured in forty gorgeous color photos from the world’s greatest underwater photographers. And for those who want to travel to these breathtaking locales, Santella provides complete “If You Go” suggestions to help you plan your trip.

Book Description
Discover the pioneering days of spearfishing and scuba diving, read about the sports early spearmen and women and the founding fathers of scuba diving in Australia. This book takes you month by month from 1917 to 1997, through the good and bad times, the discoveries, the tragedies, the undersea explorations, as well as instructor organizations, diving achievers, and a number of important events which together comprise the history of underwater diving in Australia. Within the pages of this book is a large section dealing with the Chronicle of Sport Diving, events reported as though they had recently happened, recapturing all the important occurrences that took place during 80 years since Alex Wickham first speared fish in Sydney Harbour. Special features include newspaper reports of early spearfishing, the establishment of the first spearfishing association in 1948 and the appearance of the first home-made scuba regulator. There are thrilling and sometimes tragic stories of shark attacks. A woman skin diver was lost at sea for nearly three days and nights, and survived. There is the story of Australias first and so far only world champion spearfisherman and that of two scuba divers who swam with a white pointer shark for half an hour in open water, yet were not attacked by the beast, the devastating deaths of four scuba divers in a sinkhole at Mt. Gambier, the rapid advance of underwater technology in Australia and much more. This is the only book of its kind dealing with the history of spearfishing and scuba diving in this country. For some, it will bring back old memories, for others a readable and authoritative history of spearfishing and scuba diving in Australia. For every diver, man or woman, it cannot fail to stir emotions as it recaptures exciting and historical events. At the end of the Second World War, a Frenchman, Michel Calluaud brought plans of the Gagnan-Cousteau regulator to Australia and he built one of the first in the world here. Australians could then use this equipment for work and pleasure and it has furthered their knowledge of life in the sea. As we push beyond the boundary of seashores and venture further under water we begin to discover many things that were once beyond our grasp and it is the aqualung that has enabled us to journey beyond the confinements of land. THE HISTORY OF SPEARFISHING AND SCUBA DIVING IN AUSTRALIA not only deals with the scuba diving, but also, as the title suggests, with a wealth of information concerning spearfishing and related underwater activities.
