Ein Besuch der Apnoe-Weltmeisterschaft wird für James Nestor zum Beginn eines persönlichen Abenteuers: Fasziniert von der Kompromisslosigkeit dieses Sports, erlernt er selbst das Freitauchen. Und fortan zieht es ihn immer tiefer in die verborgene Welt der Ozeane hinab: Er besucht eine Forschungsstation 20 Meter unter der Meeresoberfläche, trifft renommierten Meeresbiologen bei ihrer Arbeit, schwimmt mit Walen und geht im U-Boot auf Tauchstation. Dabei entdeckt er einen unfassbar reichen Lebensraum, mit telepathischen Korallen, leuchtenden Fischen und rätselhaften Riesenkraken. Bis er schließlich den tiefsten Punkt der Erde erreicht – die absolute Grenze für Mensch und Technik. Eine grandiose Entdeckungsreise, die zugleich unseren Wurzeln nachspürt.

Erratum: Table 11.1 on page 241 has been mis-set. The entries for the phyla Annelida, Bryozoa, Cnidaria, Echiura, Mollusca, Placozoa, Porifera and Rotifera should all be moved one column to the right. The deep sea environment is the most extensive on our planet. Its denizens are normally unseen but whenever they are exposed to view they are regarded as bizarre aliens from a different world. The Biology of the Deep Ocean takes a close look at this apparently hostile world and explains how its inhabitants are exquisitely adapted to survive and flourish within it.

Deep-Sea Biology

A Natural History of Organisms at the Deep-Sea Floor

This timely volume provides a comprehensive account of the natural history of the organisms associated with the deep-sea floor and examines their relationship with this inhospitable environment--perhaps the most remote and least accessible location on the planet. The authors begin by describing the physical and chemical nature of the deep-sea floor and the methods used to collect and study its fauna. Then they discuss the ecology of the deep sea by exploring spatial patterns, diversity, biomass, vertical zonation, and large-scale distribution of organisms. Subsequent chapters review current knowledge of feeding, respiration, reproduction, and growth processes in these communities. The unique fauna of hypothermal vents and seeps are considered separately. Finally, there is a pertinent discussion of human exploitation of deep-sea resources and potential use of this environment for waste disposal.

This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment. Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

The objective of this report is to provide an overview of the key socio-economic, management and governance issues relating to the conservation and sustainable use of deep-sea ecosystems and biodiversity. The report highlights our current understanding of these issues and identifies topics and areas that need further investigation to close gaps in knowledge. It also explores the needs and means for interfacing research with policy with a view to contributing to the political processes regarding deep-sea and high-seas governance, which are currently ongoing in various international flora within and outside the UN system. In addition, the report provides guidance on the future direction and focus of research on environmental, socio-economic and governance aspects in relation to the deep-sea.

The Ecology of Deep-sea Hydrothermal Vents

Teeming with weird and wonderful life--giant clams and mussels, tubeworms, "eyeless" shrimp, and bacteria that survive on sulfur--deep-sea hot-water springs are found along rifts where sea-floor spreading occurs. The theory of plate tectonics predicted the existence of these hydrothermal vents, but they were discovered only in 1977. Since then the sites have attracted teams of scientists seeking to understand how life can thrive in what would seem to be intolerable or extreme conditions of temperature and fluid chemistry. Some suspect that these vents even hold the key to understanding the very origins of life. Here a leading expert provides the first authoritative and comprehensive account of this research in a book intended for students, professionals, and general readers. Cindy Lee Van Dover, an ecologist, brings nearly two decades of experience and a lively writing style to the text, which is further enhanced by two hundred illustrations, including photographs of vent communities taken in situ. The book begins by explaining what is known about hydrothermal systems in terms of their deep-sea environment and their geological and chemical makeup. The coverage of microbial ecology includes a chapter on symbiosis. Symbiotic relationships are further developed in a section on physiological ecology, which includes discussions of adaptations to sulfide, thermal tolerances, and sensory adaptations. Separate chapters are devoted to trophic relationships and reproductive ecology. A chapter on community dynamics reveals what has been learned about the ways in which vent communities become established and why they persist, while a chapter on evolution and biogeography examines patterns of species diversity and evolutionary relationships within chemosynthetic ecosystems. Cognate communities such as seeps and whale skeletons come under scrutiny for their ability to support microbial and invertebrate communities that are ecologically and evolutionarily related to hydrothermal faunas. The book concludes by exploring the possibility that life originated at hydrothermal vents, a hypothesis that has had tremendous impact on our ideas about the potential for life on other planets or planetary bodies in our solar system.

The deep ocean is home to some of the most unusual of all fishes. This book is the first Fish Physiology volume devoted to these bizarre undersea creatures. Practically every organ system is affected by the constraints imposed by benthic pressure, the absence of light, and the relatively scarce supply of both food and mates. Deep Sea Fishes demonstrates how these fishes living in extremely harsh conditions metabolize, behave, and evolve.

Many organisms in deep-sea environments are extremophiles thriving in extreme conditions: high pressure, high or low temperature, or high concentrations of inorganic compounds. This book presents the microbiology of extremophiles living in the deep sea and describes the isolation, cultivation, and taxonomic identification of microorganisms retrieved from the Mariana Trench, the world's deepest point. Also explained are techniques for recovering pressure-loving bacteria, the barophiles (piezophiles), and for whole genome analysis of Bacillus halodurans C-125. Physiological analysis of the pressure effect in Saccharomyces cerevisiae and Escherichia coli is used to answer the question of how deep-sea organisms survive under high hydrostatic pressure. These research results are useful in both basic science and industrial applications. Readers discover a new microbial world in the ocean depths, with state-of-the-science information on extremophiles.

This book deals with the bottom-living fishes of the world's largest ecosystem, the deep-sea. After a brief review of the oceanographic setting, the diversity and ecology of this unique ichthyofauna are considered in detail. The book goes on to deal explicitly with slope fisheries, both developed and developing. The interaction of the ecology of the species involved (examples include orange roughy, grenadier, Greenland halibut and black scabbardfish) with fishing practices and management regimes is then discussed. An ecological framework for management is necessary for the resources to be sustainable it is argued, rather than simply extending approaches used on the Continental Shelf to the deep-sea.
