Covering 71 percent of the planet, these saline bodies of water provided the unique conditions necessary for the building blocks of life to form billions of years ago. This book explains how our oceans continue to support and influence life in important ways: by providing the largest global source of protein in the form of fish populations, by creating and influencing weather systems, and by absorbing waste streams such as airborne carbon. It is shown how oceans have an almost magnetic draw-almost half of the world's population lives within a few hours of an ocean. Although oceans are vast in size, exceeding 328 million cubic miles (1.37 billion cubic kilometers), they have been influenced by and have influenced humans in numerous ways. The book includes three detailed case studies. The first focuses on the most remote locations along the Mid-Atlantic Ridge, where new ocean floor is being formed twenty-thousand feet underwater. The second considers the Maldives, a string of islands in the Indian Ocean, where increasing sea levels may force residents to abandon some communities by 2020. The third describes the North Sea at the edge of the Arctic Ocean, where fishing stocks have been dangerously depleted as a result of multiple nations' unrelenting removal of the smallest and largest species.
The ever-increasing interest in oceanography and marine biology and its relevance to global environmental issues creates a demand for authoritative reviews summarizing the results of recent research. This annual reference has catered to this demand for more than 40 years. It considers basic areas of marine research, covers subjects of special and topical importance, and addresses new areas as they arise. This volume features papers on ecosystem-based management of marine macroalgae; the ecology and management of temperate mangroves; the biology of vestimentiferan tubeworms; precious coral exploitation; and the historical reconstruction of human-induced changes in U.S. estuaries.
An Introduction to Marine Biogeochemistry focuses on the ocean's
role in the biogeochemical cycling of selected elements and the
impact of humans on the cycling of these elements. Among the topics
covered are the chemical composition of seawater from the
perspectives of elemental speciation and the impacts of solutes on
water's physical behavior; biogeochemical phenomena which control
accumulation and preservation of marine sediments; marine chemistry
of radioactive and stable isotopes; and seawater pollution. The
book contains many examples as well as steady-state models to aid
readers in understanding this growing and complex science..
Provides a thought-provoking and original approach to the science of climate. Emphasizes that there are many factors contributing to the causation of climate change. Clarifies that while anthropogenic generation of carbon dioxide is important it is only one of several human activities contributing to climate change. Considers climate change responses needed to be undertaken by politicians and society at national and global levels. Totally revised and updated with state of the art satellite data and climate models currently in operation around the globe.
Britain's maritime tradition is well documented. The management of
its marine and coastal environment is therefore of tantamount
importance, and offers lessons for other nations across the world.
The beginning of the new millennium marks a major, long-term
turning point in the historical development of Britain's maritime
interest discernible by continued diversification and
intensification in the uses of the sea; unprecedented and often
adverse environmental impacts engendered by these uses; and the
beginning of a major effort to establish a comprehensive management
system which can deal with both multiple uses and environmental
impacts.
Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere.This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.
Although it is generally accepted that the Arctic Ocean is a very
sensitive and important region for changes in the global climate,
this region is the last major physiographic province of the earth
whose short-and long-term geological history is much less known in
comparison to other ocean regions. This lack of knowledge is mainly
caused by the major technological/logistic problems in reaching
this harsh, ice-covered region with normal research vessels and in
retrieving long and undisturbed sediment cores. During the the last
about 20 years, however, several international and
multidisciplinary ship expeditions, including the first scientific
drilling on Lomonosov Ridge in 2004, a break-through in Arctic
research, were carried out into the central Artic and its
surrounding shelf seas. Results from these expeditions have greatly
advanced our knowledge on Arctic Ocean paleoenvironments.
This book explores the factors at work in determining the past, present, and future use of the sea as an important source of protein. It serves as an adjunct text for courses in the economics of natural resources, and as a text for courses in fishery economics.
This book is an overview of the state-of-the art developments in
sedimentology of tsunami-induced and tsunami-affected deposits,
namely tsunamiites. It also points out any problems that need
additional investigation, as well as providing insight into the
direction of future tsunamiite researches. Important
characteristics of tsunami wave and tsunami currents are explained.
There are reports on the sediments generated by recent tsunami
including the 2004 Indian Ocean tsunami presented. Tsunamiites
induced by other seismic activities, a submarine slump and a
volcanic eruption are investigated as well.
Recent decades have seen a degradation of the environmental quality in semi-enclosed seas, which are particularly sensitive to population pressures due to their naturally low flushing rates related to their geometry. The North Sea, Baltic Sea and the Black Sea are amongst the most seriously threatened seas in the Euro-Asian region. Each semi-enclosed sea has a distinct pattern of circulation, transport, mixing, associated with the particular geometry, topography, boundary processes, interior stratification, atmospheric forcing, ice fonnation, straits / sill controls, and the specific inputs of freshwater, nutrients and pollutants. The workshop investigated the distinctive physical and ecological characteristics of the three seas in a comparative manner, in order to identify the types of driving forces and dynamic controls operating on productivity, nutrient cycling, physical transport and mixing mechanisms. A comparative study of these controlling mechanisms would allow us to better understand ecosystem sensitivity in these different environments. The workshop presentations highlighted the complexity of the semi-enclosed seas related to the interaction amongst the physical, chemical and biological fields, and differences in time and space scales in each of the systems. Further, a strong climate signal exists in these systems, manifest in the interannual, interdecadal and longer term variability. Part of the variability appears connected with background climatic variability.
The problems of making inferences about the natural world from noisy observations and imperfect theories occur in almost all scientific disciplines. This 2006 book addresses these problems using examples taken from geophysical fluid dynamics. It focuses on discrete formulations, both static and time-varying, known variously as inverse, state estimation or data assimilation problems. Starting with fundamental algebraic and statistical ideas, the book guides the reader through a range of inference tools including the singular value decomposition, Gauss-Markov and minimum variance estimates, Kalman filters and related smoothers, and adjoint (Lagrange multiplier) methods. The final chapters discuss a variety of practical applications to geophysical flow problems. Discrete Inverse and State Estimation Problems is an ideal introduction to the topic for graduate students and researchers in oceanography, meteorology, climate dynamics, and geophysical fluid dynamics. It is also accessible to a wider scientific audience; the only prerequisite is an understanding of linear algebra.
This book presents a new perspective on the sedimentation processes in the White Sea, based on a multidisciplinary research study conducted between 2001 and 2016. It provides a comprehensive review and discusses the latest research findings on the ecosystem of this sub-arctic zone. The topics addressed include suspended particulate matter as a main source and proxy of the sedimentation processes in the White Sea; vertical fluxes of dispersed sedimentary matter and absolute masses in the White Sea; and the development history and quaternary deposits of the modern White Sea basin. The authors closely examine the abundance and species composition of microalgae associations and the environmental conditions in the bottom sediments of the White Sea, namely, heavy metal accumulation and aliphatic and polycyclic aromatic hydrocarbons. The book ends contain a summary of the key conclusions and recommendations. Together with the companion volume Biogeochemistry of the Atmosphere, Ice and Water of the White Sea: The White Sea Environment Part I, it offers an essential source of information for postgraduate students, researchers, and stakeholders alike.
Tsunamis are long water waves generated by impulsive geophysical motions of the seafloor. They inflict significant damage and casualties both near-field and after evolving over long propagation distances and impacting distant coastlines. They can also affect geomorphologic changes along the coast. Tsunamis can be triggered by sea floor deformation, landslides, slumps, subsidence, volcanic eruptions and bolide impacts. Understanding tsunami generation is of paramount importance for protecting coastal populations at risk, coastal structures and the natural environment. generation, so that adequate discrimination of their sources from coastal inundation data is difficult. The accurate and reliable prediction of the initial waveform and the associated coastal effects of tsunamis remains one of the most vexing problems in geophysics, and - with few exceptions - has resisted routine numerical computation or off-the-shelf solutions. with contributions ranging from basic and applied science to coastal zone management. It is aimed at tsunami scientists, coastal and ocean engineers, marine geologists and geophysicists, planners and policy makers, and coastal zone managers seeking to better understand and mitigate the coastal impact of tsunamis.
Marine biogeography, the study of the spatial distribution of organisms in the world's oceans, is one of the most fascinating branches of oceanography. This book continues the pioneering research into the distributions of molluscan faunas, first studied by biologists over 160 years ago. It illustrates 1778 species of gastropods in full color, many of which are extremely rare and poorly known endemic species that are illustrated for the first time outside of their original descriptions. The spatial arrangements of malacofaunas shown in this book can be considered proxies for worldwide oceanic conditions and used as tools for determining patterns of global climate change. The book's documentation of evolutionary "hot spots" and geographically restricted endemic faunas can also be used as a base line for future studies on patterns of environmental deterioration and extinction in the marine biosphere. Documenting the evolution of the amazingly rich worldwide gastropod fauna, this book will appeal to physical and chemical oceanographers, systematic and evolutionary biologists, historical geologists, paleontologists, climatologists, geomorphologists, and physical geographers. The authors incorporate aspects of all of these disciplines into a new classification system for the nomenclature of biogeographical spatial units found in tropical, subtropical, and warm temperate seas.
This book aims to present the overall existing tsunami hazard in the Caribbean Sea region, a region which is typically only associated with hurricanes. It initially presents an overview of all of the existing tsunami-causing factors found in the region: earthquakes, sub-aerial and submarine landslides, and submarine explosions. This is followed by field evidence of recent and pre-historic tsunami events, which gives credibility to all of this effort. The next section is a description of the tsunami hazard mitigation efforts being carried out locally and in collaboration with national and international programs. The final part is dedicated to the presentation of related recent research results.
Australia and Canada have been at the forefront of efforts to operationalize integrated oceans and coastal management. Throughout the 1990s both countries devoted considerable effort to developing strategies to give effect to international ocean management obligations. This key book focuses on principles of marine environmental conservation and management, maritime regulation and enforcement, and regional maritime planning and implementation. With contributions from respected scholars, this informative book collectively assesses the obligations, compliance, implementation and trends in international ocean law, particularly in giving effect to an Oceans Policy, regional maritime planning, international oceans governance, and maritime security. This book will be of interest to all academics involved with maritime studies and international law.
Finally, someone has written a comprehensive, easily readable explanation of the tides on earth that is both simple enough for students and solid enough for their professors. Step by step, by analogy and illustration, Beyond the Moon describes how the cyclical motion of the near solar system is impressed upon the earth's oceans, and how the hydraulics over the continental shelf and the geography of the coastline orchestrate this rhythm into the bewildering variety of tide patterns seen around the globe. This volume demystifies the complexity of the tides by systematically examining its many constituents and demonstrates that: "Nature is, at once, awesome in complexity and beautiful in simplicity."
This textbook introduces research on dinosaurs by describing the science behind how we know what we know about dinosaurs. A wide range of topics is covered, from fossils and taphonomy to dinosaur physiology, evolution, and extinction. In addition, sedimentology, paleo-tectonics, and non-dinosaurian Mesozoic life are discussed. There is a special opportunity to capitalize on the enthusiasm for dinosaurs that students bring to classrooms to foster a deeper engagement in all sciences. Students are encouraged to synthesize information, employ critical thinking, construct hypotheses, devise methods to test these hypotheses, and come to new defensible conclusions, just as paleontologists do.

Mass Transport, Gravity Flows, and Bottom Currents: Downslope and Alongslope Processes and Deposits focuses solely on important downslope and alongslope processes. The book provides clear definitions and characteristics based on soil mechanics, fluid mechanics and sediment concentration by volume. It addresses Slides, Slumps, and Debris Flows, Grain Flows, Liquefied/Fluidized Flows, and Turbidity Currents, Density plumes, Hyperpycnal Flows, the Triggering Mechanisms of Downslope Processes, Bottom Currents, and Soft-Sediment Deformation Structures. The mechanics of each process are described in detail and used to provide empirically-driven categories to help recognize these deposits it the rock record. Case studies clearly illustrate of the problems inherent in recognizing these processes in the rock record, and potential solutions are provided alongside future avenues of research. An appendix also provides step-by-step guidance in describing and interpreting sediments.
The theory of waves is generalized on cases of strongly nonlinear waves, multivalued waves, and particle-waves. The appearance of these waves in various continuous media and physical fields is explained by resonances and nonlinearity effects. Extreme waves emerging in different artificial and natural systems from atom scale to the Universe are explored. Vast amounts of experimental data and comparisons of them with the results of the developed theory are presented. The book was written for graduate students as well as for researchers and engineers in the fields of geophysics, nonlinear wave studies, cosmology, physical oceanography, and ocean and coastal engineering. It is designed as a professional reference for those working in the wave analysis and modeling fields.
Modeling of Extreme Waves in Technology and Nature is a two-volume set, comprising Evolution of Extreme Waves and Resonances (Volume I) and Extreme Waves and Shock-Excited Processes in Structures and Space Objects (Volume II). The theory of waves is generalized on cases of extreme waves. The formation and propagation of extreme waves of various physical and mechanical nature (surface, elastoplastic, fracture, thermal, evaporation) in liquid and solid media, and in structural elements contacting with bubbly and cryogenic liquids are considered analytically and numerically. The occurrence of tsunamis, giant ocean waves, turbulence, and different particle-waves is described as resonant natural phenomena. Nonstationary and periodic waves are considered using models of continuum. The change in the state of matter is taken into account using wide-range determining equations. The desire for the simplest and at the same time general description of extreme wave phenomena that takes the reader to the latest achievements of science is the main thing that characterizes this book and is revolutionary for wave theory. A description of a huge number of observations, experimental data, and calculations is also given. |
