Ecosystems of the Deep Oceans by P.A. Tyler Pdf

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.

Brazilian Deep-Sea Biodiversity by Paulo Yukio Gomes Sumida,Angelo Fraga Bernardino,Fabio Cabrera De Léo Pdf

This book presents the biodiversity of the Brazilian deep-sea and its many unique geological and biological features, as well as a review of its ecology, conservation, and future research needs. The deep-sea Brazilian margin has an incredible geological heterogeneity with numerous characteristic seafloor features, and latitudinal changes in marine productivity, oceanographic conditions and biological communities have resulted in very distinct biological assemblages at regional and bathymetric scales. It is a tremendously rich ecosystem in terms of living species, from which many well-known historical tales have originated, and with unique importance for the global climate and humanity. Nevertheless, vast areas of the Brazilian margin have been explored for fishing, oil and gas, and other commodities, likely impacting a variety of deep-sea habitats at scales and intensities yet undetermined. This book is intended for students, scholars, professionals and a wide audience interested in the deep-sea in general and, more specifically, in the South Atlantic deep-sea.

The Law of the Seabed by Catherine Banet Pdf

The Law of the Seabed reviews the most pressing legal questions raised by the use and protection of natural resources on and underneath the world’s seabeds. While barely accessible, the seabed plays a major role in the Earth’s ecological balance. It is both a medium and a resource, and is central to the blue economy. New uses and new knowledge about seabed ecosystems, and the risks of disputes due to competing interests, urge reflection on which regulatory approaches to pursue. The regulation of ocean activities is essentially sector-based, and the book puts in parallel the international and national regimes for seabed mining, oil and gas, energy generation, bottom fisheries, marine genetic resources, carbon sequestration and maritime security operations, both within and beyond the national jurisdiction. The book contains seven parts respectively addressing the definition of the seabed from a multidisciplinary perspective, the principles of jurisdiction delimitation under the United Nations Convention on the Law of the Sea (UNCLOS), the regimes for use of non-living, living and marine biodiversity resources, the role of state and non-state actors, the laying and removal of installations, the principles for sustainable and equitable use (common heritage of mankind, precaution, benefit sharing), and management tools to ensure coexistence between activities as well as the protection of the marine environment.

Methods for the Study of Deep-Sea Sediments, Their Functioning and Biodiversity by Roberto Danovaro Pdf

For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine species existing in an ecologically stable and uniform environment. Recent discoveries have completely transformed that understanding and the deep sea is recognized as a complicated and dynamic environment with a rich diversity of marine species. Carefully designed to provide practical information in an easily accessible format, Methods for the Study of Deep-Sea Sediments, Their Functioning, and Biodiversity covers how to investigate the biological components through analysis of their biodiversity. It also provides the protocols and methodological details needed to investigate some aspects of the functional biodiversity of variables commonly utilized to describe and understand the drivers of deep-sea ecosystem functioning. This volume contains detailed protocols for analyzing all benthic components from benthic viruses, prokaryotes, protozoa, foraminifera, to meio-, macro-, and megafauna. It includes step-by-step procedures, with additional notes on the crucial steps or possible difficulties arising from the analysis. Each chapter provides a brief introduction, a description of the sampling procedures and/or the sample treatment, and then the laboratory protocols, providing information on instrument setting and/or the solutions utilized. Each chapter also contains a visual scheme of the protocol for use during laboratory activities and for tracking each laboratory step. Linking information on biodiversity with the functioning of the marine ecosystems, the book covers all living components of the benthos. It provides practical information for anyone studying deep-sea habitats, their characteristics, functioning, and biodiversity.

Biological Sampling in the Deep Sea by Malcolm R. Clark,Mireille Consalvey,Ashley A. Rowden Pdf

The deep sea covers over 60% of the surface of the earth, yet less than 1% has been scientifically investigated. There is growing pressure on deep-sea resources and on researchers to deliver information on biodiversity and the effects of human impacts on deep-sea ecosystems. Although scientific knowledge has increased rapidly in recent decades, there exist large gaps in global sampling coverage of the deep sea, and major efforts continue to be directed into offshore research. Biological Sampling in the Deep Sea represents the first comprehensive compilation of deep-sea sampling methodologies for a range of habitats. It reviews the real life applications of current, and in some instances developing, deep-sea sampling tools and techniques. In creating this book the authors have been able to draw upon the experiences of those at the coal face of deep-sea sampling, expanding on the existing methodological texts whilst encompassing a level of technical detail often omitted from journal publications. Ultimately the book will promote international consistency in sampling approaches and data collection, advance the integration of information into global databases, and facilitate improved data analyses and consequently uptake of science results for the management and conservation of the deep-sea environment. The book will appeal to a range of readers, including students, early-career through to seasoned researchers, as well as environmental managers and policy makers wishing to understand how the deep-sea is sampled, the challenges associated with deep survey work, and the type of information that can be obtained.

Economic value of ecosystem services from the deep seas and the areas beyond national jurisdiction by Food and Agriculture Organization of the United Nations,Ottaviani, D. Pdf

This circular stems from a study carried out for FAO projects “Sustainable Fisheries Management and Biodiversity Conservation of Deep-Sea Living Marine Resources and Ecosystems in the Areas Beyond National Jurisdiction” (GCP/GLO/366/GFF) and “Deep-Sea Sponge Grounds Ecosystems of the North Atlantic: An Integrated Approach Towards their Preservation and Sustainable Exploitation” (GCP/GLO/679/EC). These projects included outputs related to the economic valuation of goods and services provided by the deep seas in areas beyond national jurisdiction. This study compiled an estimate of the total economic value (TEV) of the deep seas, which considered the provision of deep-water fish, the harvest of precious corals, the use of substances of marine origin as pharmaceuticals, the extraction of deep and ultra-deep oil and the potential mining of mineral resources from the seafloor, carbon sequestration carried out by the deep seas, the importance of scientific research in the deep seas, and touristic activities with submersibles to visit sites such as the Titanic shipwreck. Comprehensively, the TEV assessed for the deep-sea ecosystem as a whole is estimated at USD 267 billion per year. Ninety two percent of the economic value originates from abiotic resources (oil and minerals), 5 percent from biotic resources (fish, corals and pharmaceuticals of marine origin), 2 percent from cultural services (scientific research and tourism/recreation), and 1 percent from carbon sequestration.
