Book Description
This book is the comprehensive volume of the TAIGA (“a great river ” in Japanese) project. Supported by the Japanese government, the project examined the hypothesis that the subseafloor fluid advection system (subseafloor TAIGA) can be categorized into four types, TAIGAs of sulfur, hydrogen, carbon (methane), and iron, according to the most dominant reducing substance, and the chemolithoautotrophic bacteria/archaea that are inextricably associated with respective types of TAIGAs which are strongly affected by their geological background such as surrounding host rocks and tectonic settings. Sub-seafloor ecosystems are sustained by hydrothermal circulation or TAIGA that carry chemical energy to the chemosynthetic microbes living in an extreme environment. The results of the project have been summarized comprehensively in 50 chapters, and this book provides an overall introduction and relevant topics on the mid-ocean ridge system of the Indian Ocean and on the arc-backarc systems of the Southern Mariana Trough and Okinawa Trough.

Book Description
Systems Biogeochemistry of Major Marine Biomes A comprehensive system-level discussion of the geomicrobiology of the Earth’s oceans In Systems Biogeochemistry of Major Marine Biomes, a team of distinguished researchers delivers a systemic overview of biogeochemistry across a number of major physiographies of the global ocean: the waters and sediments overlying continental margins; the deep sub-surfaces; the Arctic and Antarctic oceans; and the physicochemical extremes such as the hypersaline and sulfidic marine zones, cold methane seeps and hydrothermal ecosystems. The book explores state-of-the-art advances in marine geomicrobiology and investigates the drivers of biogeochemical processes. It highlights the imperatives of the unique, fringe, and cryptic processes while studying the geological manifestations and ecological feedbacks of in situ microbial metabolisms. Taking a holistic approach toward the understanding of marine biogeochemical provinces, this book emphasizes the centrality of culture-dependent and culture-independent (meta-omics-based) microbiological information within a systems biogeochemistry framework. Perfect for researchers and scientists in the fields of geochemistry, geophysics, geomicrobiology, oceanography, and marine science, Systems Biogeochemistry of Major Marine Biomes will also earn a place in the libraries of policymakers and advanced graduate students seeking a one-stop reference on marine biogeochemistry.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 144. Awareness has grown over the past several years that the subseafloor may harbor a substantial biosphere sustained by volcanic heat and chemical fluxes from the Earth's interior. This realization has profound scientific implications for questions concerning the origins of life, the true extent of Earth's biosphere, and the search for life on other planets. At mid-ocean spreading centers, the fluxes that sustain life are the highest, and the hydrothermal fluids in which micro-organisms grow are readily accessible on the seafloor. In addition, periodic volcanic eruptions flush fluids and microbes from the subsurface, and volcanic gases are believed to drive spectacular microbial blooms. Although ridges are challenging locations in which to work, they are unique in the oceans because of the diversity and dynamic nature of their subsurface environments.

Book Description
In the last decade, the concept of a Blue Economy has ignited a deep theoretical debate. Ranging from the integration of the triple bottom line of sustainability to the optimization of profit from ocean exploitation, the meaning of the term blue economy differs considerably between epistemic communities and even more so among national and regional policies. There is a general sense of the opportunity to realise enhanced social and economic benefits from the sustainable utilisation of their ocean and coastal resources under the umbrella framework of blue economy. Blue economy is gaining traction already as a significant component of national policies, even in spite of a clear conceptualization of the term. Many countries are now preparing national policies towards realising their blue economy ambitions, utilizing the concept as they see fit. Likewise, multilateral and regional organisations are developing guidelines, and providing investment in new research, technologies, and financing tools that promote blue economy. Critical challenges abound, in particular in less privileged countries. These include the gap in research capabilities, governments prioritizing social wellbeing and economic profit in contrast to environmental protection, the identification of new and emerging areas of ocean economic activity that are both socially and ecologically sustainable and holds viable business models that can attract private investment.

Book Description
This book is the third volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. It is devoted to the remaining Sedentaria and the first branches of Errantia. These sedentary polychaetes are Terebellida and Arenicolida, all of which are tube-dwelling and deposit feeders. The tubes may be simple burrows stabilized by mucus or the tubes are highly sophisticated often really aesthetic structures build-up of sediment grains glued together by their secretion. Although the former possess anterior appendages used for collecting food particles, these are likely not modified palps rather than a new acquisition. Many of these species are adapted to occur within environments characterized by low oxygen supply and so many members of these taxa possess elaborated branchiae, usually positioned on a number of anterior body segments except for Maldanidae which look like bamboo sticks and thus earned their common name bamboo worms. Members of Arenicolida and Maldanida may occur in high abundance and as such they create biogenically graded sediment beds. The Errantia part starts with Myzostomida, a group of symbiotic animals associated with echinoderms which have been variously placed within the tree of life. As such they show numerous adaptations to this specific mode of life. The next group discussed within Errantia is Protodrilida, a taxon comprising four families of the former archiannelids which belong to the interstitial fauna. Most likely they evolved by miniaturization from larger ancestors. In contrast to typical errants they do not possess well-developed parapodia and antennae. This taxon is followed by Eunicida characterized by possession of a specific jaw apparatus situated ventrally in the foregut and associated with specific musculature. Also being a species rich group showing various feeding modes some of the smallest and the largest members belong to this taxon.
