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.
During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.
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.
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.
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. Oceanography and Marine Biology: An Annual Review has answered this demand since its founding by the late Harold Barnes more than forty years ago. Its objective is an annual consideration of basic areas of marine research, dealing with subjects of special or immediate importance, adding new subjects as they arise. The volumes maintain a unified perspective on the marine sciences. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. This essential reference text for researchers and students in all fields of marine science finds a place in libraries of marine stations and institutes, as well as universities. It consistently ranks among the highest in impact factors for the marine biology category of the citation indices compiled by the Institute for Scientific Information. Volume 43 contains analysis on cold seep sediments, unburnt coal in the marine environment, biofiltration and biofouling on artificial structures in Europe, ecology of rafting in marine ecosystems, effects of globalisation in marine environments, and much more.
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.
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."

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.
Highlighting twenty years of U.S. scientific research conducted since the International Geophysical Year (IGY) of 1957-58, this volume marks a turning point in the history of polar investigations and provides a lucid summary of the contributions of many distinguished scientists. The authors provide an overview of major polar research programs, past and present; explore concepts derived, from highly interrelated aspects of physical and life sciences; and seek to offer a glimpse of future polar science and polar development. The introduction briefly describes major physical, biological, and interdisciplinary research programs, as well as the magnitude, extent, and international character of contemporary polar science. Twenty years of polar biological investigations are then reviewed, and subsequent chapters address principles and advances in meteorology, physical oceanography, glaciology, and the geological evidence that hears on the origin of Antarctica. These physical sciences delineate a matrix for the polar biospheres and provide a background for understanding the major categories of structure and dynamic functioning of the marine ecosystem, polar marine mammals, adaptational physiology, and terrestrial biotic adaptations.

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 sea has been the site of radical changes in human lives and national histories. It has been an agent of colonial oppression but also of indigenous resistance, a site of loss, dispersal and enforced migration but also of new forms of solidarity and affective kinship. "Sea Changes "re-evaluates the view that history happens mainly on dry land and makes the case for a creative reinterpretation of the role of the sea: not merely as a passage from one country to the next, but a historical site deserving close study.
Did you know that the Grand Bank earthquake of 1929 triggered a huge submarine mass movement which broke submarine cables over a distance of up to 1000 km from its source and generated a tsunami which devastated a small village in Newfoundland killing 27 people? The same happened in Papua New Guinea in 1998 with more than 2000 casualties. Submarine mass movements of various sizes and styles are shaping the sea floor and are of concern for many facets of human activities both onshore and offshore. These include the development of natural resources, energy and communication transport, coastal infrastructures and communities. This book provides a world-wide perspective of submarine mass movements and their consequences. This has been made possible by assembling excellent contributions from active researchers, groups, or institutions, thus providing full coverage of the many scientific and engineering aspects of this type of marine and coastal geo-hazard. It covers fundamental as well as site specific studies from many areas including the Atlantic and Pacific oceans, inner seas like the Mediterranean Sea, and fjords using the most recent technologies from multibeam sonar imaging techniques, 3D seismic analysis, slope stability analysis, to debris flow and tsunami modeling. Audience: This book is of interest to any researcher in the field of marine and coastal geo-hazards. It will be useful for planners, scientists and engineers involved in the development of offshore and near-shore resources and also to those in charge of the management and mitigation of coastal hazards. For graduate students, this book provides an up-to-date vision of the process of submarine mass movements and theirconsequences from both a scientific and an engineering standpoint, and it includes a unique collection of the existing literature on marine geo-hazards. CD-Rom included
This is more than the story of a voyage. It is the story of Bernard and Francoise MoitessierAs honeymoon voyage from Europe to the islands of the Pacific and back by way of Cape Horn. Setting out from Tahiti, they took the alogical routeA back because it was the fastest, taking them through the Roaring Forties, through the high attitudes of relentless gale-force winds, and through iceberg territory. Their survival was due to great seamanship, careful preparation, and perhaps also their sense of harmony with JOSHUA and the sea. It is the story of JOSHUA (named for their sailing hero, Joshua Slocum), the dreamboat that became a reality, of how Moitessier recovered from the disaster of losing his previous boat u which he built himself u to pursue his great love, sailing the worldAs oceans. It is also a marinerAs guide to the pleasures and perils of sailing the Trade Winds, the archipelagos of the Pacific, and the Cape Horn route including preparation suggestions and the sailing survival knowledge that made the MoitessierAs voyage successful and joyous. Bernard Moitessier was one of the worldAs great small-boat sailors, and he displays his skills and knowledge in this book. He writes
The Whale in the Living Room follows the thrilling adventures of film-maker, John Ruthven, as he travels the globe, dives into our oceans and passionately recounts his life-affirming experiences. What creatures could remain undiscovered in the 95 per cent of the seas that have not been thoroughly explored? How vast, really, are our oceans? The surface of Mars and Venus are better known to us than Earth's seabed. Yet to map the world's ocean to even 100-metre blocks of accuracy, something that environmentalists say is essential for its protection, could take another 300 years. Even creatures that are known to us, like the giant squid, have proved too difficult to accurately capture on film. Quite literally immersed in his subject, John can help readers understand the magnitude of our planet's oceans and why it is so important for us to protect our seas and the creatures that inhabit them. He is the only producer to have worked full-time on both series of Blue Planet, as well as nearly fifty other films about the sea. Through his first-hand experience, John shows us the loneliness of whale calves in the deep blue, the fear of seals as they dodge great white sharks near the coast, or the curiosity of octopus staring back at us through the camera. His book takes us through the blue rings of South Pacific coral atolls, on submarine rides into the abyss with ancient life forms, and up close and personal encounters with singing humpback whales that make you feel the water around you. The Whale in the Living Room, like the proverbial 'elephant in the room', is also about how, until recently, we have been largely blind to our polluting of the seas. John, for example, explores how plastic 'went wild' in the ocean; tries to understand how we got into this mess; and see if we can ever untangle the oceans from its grip.
Written by Chris Maser, one of the architects of the sustainability movement, Interactions of Land, Ocean and Humans: A Global Perspective explores a critical number of the myriad aspects that comprise the great, reciprocal feedback loops between the mountain peaks, the deep sea, and everywhere in between. Maser's exploration of these connections gives us the tools required to open our imaginations and our scientific literacy, offering insights into the relationships between the land, sea, and people that could influence us toward better decisions. The author examines the hydrological cycle, hydrological continuum, and anthropogenic pollution of various kinds from the atmosphere to deep belowground. He also highlights connections by detailing how human behavior changes the atmosphere, which changes the oceans, which alters the climate, which alters the atmosphere and thus the ocean, and so on. The book then explores the biophysical commonalities between landscapes and seascapes, as well as the habitats, in each realm. It covers marine fisheries; marine protected areas; oceans as a commodity, as part of the global commons, as a biophysical living trust for which we are the trustees and the children of today and beyond are the beneficiaries; and more. Can we arrest this deleterious process? Yes, but it will take a dramatic shift in human behavior worldwide. Why? Because, just as the collective human behavior and lack of awareness caused the problems in the first place, the level of consciousness that caused the problem is not the level of consciousness that can fix it. We must shift our thinking from that which is symptomatic to that which is systemic if we are to have a sustainably productive environment through time. Maser gives us the understanding of the biophysical interactions among the lands, oceans, and peoples of the world needed to create sustainable solutions to environmental problems.
