Increasing population, expanding industry and commerce, and tourism are placing added pressures on an already highly-utilized coastal zone. This book, through a series of case studies, illustrates the variety of changes already made along the coastlines of the world. The examples used are mainly from China, Japan, The Netherlands, and the United States, all countries with extensively engineered shorelines. Modifications emphasized include those associated with protection against coastal erosion, building of artificial beaches and islands, reclamation for aquaculture and agriculture, and the construction of harbors. The information in this book should be useful for all planners and engineers involved in the construction of coastal engineering works and for students interested in coastal modification.
Annals of natural disasters have always caused common interest. Scientists and specialists of various domains, teachers, students, post-graduates, journalists .. and merely inquisitive can find useful and didactic information in such annals~ Sad experience of the natural disasters endured gives very important material for humanity. It allows us not only to understand better the phenomenon itself, but also to prepare ourselves for future cataclysms, which our "Mother-Nature" is so rich in. The book by Sergey Soloviev and a group of his collaborators represents a detailed description of tsunami waves and accompanying phenomena in the Mediterranean Sea over a period of approximately four thousand years. Sergey Soloviev, the founder and recognised leader of the Russian scientific school of tsunami researchers, was unable to see the publication of this book, passing away on March 9, 1994. However, his ample experience in investigation and systematisation of tsunami waves for the Pacific area [Soloviev and Go, 1974, 1975; Soloviev, Go and Kim, 1986] has been widely used in compiling this book. The Mediterranean coasts are the cradle of civilisation. Written accounts of past disasters in this region of the Earth are rather numerous and highly reliable. Therefore the results of the tsunami study in the Mediterranean Sea are of specific value both for the scientific community and for humanity at large.
This book provides an up-to-date introduction to the theory of
sound propagation in the ocean. The text treats both ray and wave
propagation and pays considerable attention to stochastic problems
such as the scattering of sound at rough surfaces and random
inhomogeneities. An introductory chapter that discusses the basic
experimental data complements the following theoretical chapters.
This unique collaboration of Russian and Norwegian scientists examines the most recent data on the White Sea bathymetry, examines the ecosystem profile, and provides extensive historical marine and riverine data records. The book presents extensive data and numerical modelling simulations of the White Sea to provide a quantitative assessment of vulnerability of the Sea 's marine ecosystems, of future anthropogenic and climate change forcing.
This book fills a gap in knowledge of breaking waves and their influence on the generation of marine fluxes from ocean surfaces. Based on published data as well as on the author's experience, the text explores in detail the relationship chain of breaking waves, whitecaps coverage, rate of wave energy dissipation, amount of aerosol fluxes rising from a given sea basin, and possible seasonal variations.
A coastal sea area usually indicates a sea area between a continental shelf break with a water depth of about 200 m and the land shore. About 70% of global fish resources spend part of their life cycle in the coastal seas, which accounts for 90% of marine biomass yield. Freshwater and nutrients from the land have a great influence on the coastal seas, especially since more than half the human population lives within 100 km of a coast. Chemical reactions occur there rapidly between substances from the land as they encounter substances from the ocean. In terms of physics, a coastal sea acts as a boundary layer and kinetic energy is actively exchanged there. But if coastal oceanography were to be summed up in a single sentence, it would be the study that quantitatively makes clear the material transport in the coastal sea area'. Because the physical, chemical and biological processes relate to the material transport in the sea, it can be said the coastal oceanography is a genuinely interdisciplinary study. This book clarifies the quantitative material transport processes in the coastal sea area, mainly from a physical viewpoint.
We are only now beginning to understand the climatic impact of the remarkable events that are now occurring in subarctic waters. Researchers, however, have yet to agree upon a predictive model that links change in our northern seas to climate. This volume brings together the body of evidence needed to develop climate models that quantify the ocean exchanges through subarctic seas, measure their variability, and gauge their impact on climate.
Recent studies suggest that tropical cyclones are more powerful than in the past with the most dramatic increase in the North Atlantic. The increase is correlated with an increase in ocean temperature. A debate concerns the nature of these increases with some scientists attributing them to a natural climate fluctuation and others suggesting climate change related to anthropogenic increases in forcing from greenhouse gases. A Summit on Hurricanes and Climate Change was held during the spring of 2007 on the island of Crete that brought together leading academics and researchers on both sides of the scientific debate to discuss new research and express opinions about what will happen in the future with regard to hurricane activity. This proceedings volume highlights the state-of-the-science research into various aspects of the hurricane-climate connection. It is likely that the science presented here will lead to new research that will help answer crucial questions about our sustainable future.
An up-to-date summary of our understanding of the dynamics and thermodynamics of moist atmospheric convection, with a strong focus on recent developments in the field. The book also reviews ways in which moist convection may be parameterised in large-scale numerical models - a field in which there is still some controversy - and discusses the implications of convection for large-scale flow. Audience: The book is aimed at the graduate level and research meteorologists as well as scientists in other disciplines who need to know more about moist convection and its representation in numerical models.
Persistent organic contaminants, which are bioaccumulative and toxic are a concern for the ecosystems and human health and are regulated under international law (global and regional conventions, besides other). If semivolatile, they cycle in different environmental compartments and follow complex transport pathways. The ocean is believed to play a key role in the cycling by accumulating and storing the contaminant and providing a transport medium. But substance fate in the marine environment is not fully understood yet. Here, the global multicompartment chemistry-transport model MPI-MCTM is used to study the fate of organic pollutants in the marine and total environment. For the first time historical emission data are used in spatially-resolved long-term simulations of an insecticide, DDT, and an industrial chemical, perfluorooctanoic acid (PFOA). The model results give new insights into the cycling of these substances as different spatial and process resolutions were tested. E.g. for DDT the model results show saturation and reversal of air-sea exchange, which was not indicated by any other study before.
How do you dig up a 13,000 year-old footprint? Why do kelp forests need sea otters? How do you measure a shrinking glacier from an airplane? What is a 'zombie urchin'? Heart of the Coast brings these questions to life in a deep exploration of the beauty, mystery and biodiversity of the Pacific coast. Join Hakai Institute researchers in the field-archaeologists, oceanographers, marine biologists and beyond-as they journey from the ice fields of Klinaklini Glacier to the dazzling undersea reefs of a place called Crazy Town. British Columbia's Central Coast is a rich landscape called "a biologist's dream" and "the Amazon of the north." Since launching its Calvert Island ecological observatory there in 2009, the Hakai Institute has become a renowned centre of science and exploration. Collaborations with the Smithsonian Institution, the Monterey Bay Aquarium, and several First Nations on the BC coast--along with a wide array of scientists hailing from other agencies and universities across North America-have uncovered new species, advanced our knowledge of marine food webs, and helped track the effects of climate change on watersheds and coastal ecosystems. Stunning photography illuminates the institute's journey of discovery over the past decade. This unforgettable book will inspire you with wonder and awe for the natural world, but be careful-you may learn something along the way.
It is only in the past few years that methods of adequate sensitivity have become available for true ultra-trace metal determinations in water. In the case of organics in seawater it has now become possible to resolve the complex mixtures of organics in seawater and achieve the required very low detection limits. Fortunately, the interest in micro-constituents in the seawater both from the environmental and the nutrient balance points of view has coincided with the availability of advanced instrumentation capable of meeting the analytical needs. This complete and up-to-date compilation of the currently employed proven methods for the chemical analysis of seawaters includes 45 tables and 48 figures. The author presents the methods in a logical manner so that the reader can readily learn how to perform them and understand the types of instrumentation available. It helps the practitioner to implement these methods successfully into his laboratory and to apply them quickly and reliably. In addition, the detailed description of each method enables the analyst to set up new analytical methods meeting the needs for the detection of new analytes. The volume covers all aspects of the analysis of seawater using both classical and the most advanced recently introduced physical techniques. It is an invaluable source for the analysts, oceanographers, fisheries experts, politicians and decision maker engaged in seawater environmental protection.

Life on Earth emerged under anaerobic conditions. Many fundamental b- chemical and metabolic pathways evolved before the atmosphere contained oxygen. Today, anaerobic (anoxic) conditions in marine milieus are generally restricted to sediments and to basins isolated from oxygenated deep-sea cir- lation. Oxygen-de?cientorhypoxicconditionsarede?nedinoperationalterms. In speaking of the degree of O -de?ciency, the term hypoxic is usually de?ned 2 as ranging between 22 and 64?MofO , while suboxic refers to a range below 2 10?M, and anoxic is the complete absence of oxygen. Biologists commonly use the term hypoxia to describe the point at which animals suffocate. But the papers presented in this book deal with the whole range of oxygen-de?cient conditions, and the de?nitions some authors have used here may vary. Enhanced oxygen consumption by decomposition of organic matter and slow downward mixing and diffusion of dissolved oxygen from the surface waters can lead to oxygen de?ciency in the water column in highly productive waters, forming the Oxygen Minimum Zone (OMZ). Bottom waters of coastal upwelling regions are frequently exposed to hypoxic (suboxic) or anaerobic conditions owing to extremely high primary productivity. The development of these conditions represents an acute perturbation to ecological dynamics and ?sheries. Inthepast,anoxicconditionsinthewatercolumnmayhavedeveloped morereadily.

Until 1997, few people had heard of the seasonal current that Peruvians nicknamed El Nino. But when meteorologists linked it to devastating floods in California, severe droughts in Indonesia, and strange weather everywhere, its name became entrenched in the common parlance faster than a typhoon making landfall. Bumper stickers appeared bearing the phrase "Don't blame me; blame El Nino." Stockbrokers muttered "El Nino" when the market became erratic. What's behind this fascinating natural phenomenon, and how did our perceptions of it change? In this captivating book, renowned oceanographer George Philander engages readers in lucid and stimulating discussions of the scientific, political, economic and cultural developments that shaped our perceptions of this force of nature. The book begins by outlining the history of El Nino, an innocuous current that appears off the coast of Peru around Christmastime--its name refers to the Child Jesus--and originally was welcomed as a blessing. It goes on to explore how our perceptions of El Nino were transformed, not because the phenomenon changed, but because we did. Philander argues persuasively that familiarity with the different facets of our affair with El Nino--our wealth of experience in dealing with natural hazards such as severe storms and prolonged droughts--can help us cope with an urgent and controversial environmental problem of our own making--global warming. Intellectually invigorating and a joy to read, "Our Affair with El Nino" is an important contribution to the debate about the relationship between scientific knowledge and public affairs."
How do beaches function? Where do the waves come from, and why are
they always parallel to the shore, no matter which way the shore
faces? Where does sand come from, and why are some beaches grey,
some white, some beige? What plants and animals live there, and how
do they deal with this harsh, plastic environment?
Connecting Europe, Asia, and Africa, the Mediterranean Sea has been
for millennia the place where religions, economies, and political
systems met, clashed, influenced and absorbed one another. In this
brilliant and expansive book, David Abulafia offers a fresh
perspective by focusing on the sea itself: its practical importance
for transport and sustenance; its dynamic role in the rise and fall
of empires; and the remarkable cast of characters-sailors,
merchants, migrants, pirates, pilgrims-who have crossed and
re-crossed it.

Estuaries are productive ecosystems of high ecological value. They are important habitats for various species and those of highest value are protected by national and international conventions. This book highlights possible pollution impacts in a protected estuarine ecosystem, Amvrakikos Gulf, considered as one of the most important wetlands in Greece. In addition, the Changjiang (Yangtze) River is known to contribute significantly to the ecosystems of the Changjiang River estuary and adjacent waters. In this book, some long-term data of freshwater discharge, sediment load, nutrient concentrations and compositions in the river and estuary waters are presented, as well as the long-term response of the ecosystem in the estuary. Moreover, the literature on modern estuarine diatoms from Argentina is revised in order to synthesise the available ecological information and to detect possible modern analogues for Quaternary diatom assemblages. The authors also discuss negative or inverse estuaries, those where seawater is concentrated by the removal of fresh water, in the Northern Gulf of California. The challenges facing the sustainable management of temporarily open/closed estuaries (TOCEs) is addressed as well, critical in some cases because their ecological integrity, biodiversity and nursery function have already been compromised. |
