Book Description
This book presents the results from the Japanese Fisheries Research Agency’s 3-year intensive monitoring of radionuclides in a variety of fish, plankton, benthos, and their living environments after the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in March 2011. The book reveals the dynamics of contamination processes in marine and freshwater fish, mediated by the contamination of water, sediments, and food organisms; it also clarifies the mechanisms by which large variations in the level of contamination occurs among individual fish. Most importantly, the book includes a large amount of original measurement data collected in situ and for the first time assesses diffusion of radiocesium across the Pacific using both in situ data and a numerical simulation model. Also introduced are several new approaches to evaluate the impact of the release of radionuclides, including the measurement of radiation emission from an otolith section to identify the main period of contamination in fish. The FNPP accident represents a rare instance where the environmental radioactivity level was elevated steeply through atmospheric fallout and direct discharge of radioactive water into the sea over a short period of time. Replete with precise scientific data, this book will serve as an important resource for research in fields such as fishery science, oceanography, ecology, and environmentology, and also as a solid basis for protecting fisheries from damage resulting from harmful rumors among the general public.

Book Description
Analysis of Seawater deals with the investigation of the micro-constituents in seawater in terms of nutrient content and environmental concerns. The book describes sampling, determination of anions, analysis of dissolved gases, and metal preconcentration techniques. The book also deals with monitoring radioactive elements, the determination of seawater organics, organometallic compounds, and the oxygen-demand parameters in seawater. It describes in detail surface and deep water sampling, the types of devices used, storage, preservation, and prevention of contamination during sample analysis. In examining dissolved gases, the investigator can use the amperometric titrimetric method (with some reservations) on chlorine, the ultraviolet method on ozone, electron capture gas chromatography on nitric oxide, and also the flow injection analysis on hydrogen sulphide. The methods for determining metals in seawater concern either for single element or for groups of elements. The investigator should always initiate various pre-concentration techniques when determining metals due to their low concentration and occurrence in seawater. The investigator uses various methods to determine different radioactive compounds such as uranium, polonium, thorium, radium, barium, radon, plutonium, strontium-90, and cesium-137. The book can be beneficial for meteorologists, environmentalists, marine ecologists, biologists, oceanographers, fisheries experts, for students studying hydrology, meteorology, as well as for river and lake authorities.

Book Description
This volume discusses major areas of primary concern for the understanding of the complexity associated with ecological trace element research. These include sources and fates of trace elements; analytical techniques; and the distribution of trace elements in biota and soil and sediment reservoirs. Case studies, field work and laboratory studies intensively discussed in this volume are useful to enhance our knowledge about processes related to the biological response of trace metal stress under realistic environmental conditions.

Book Description
The Norwich Symposium, 'Radionuclides in the Study of Marine Proces ses', is a sequel to the very successful conference held at Cherbourg, France in June 1987. The international character of the meeting has been maintained with thirty-eight contributions, from seventeen countries, being accepted for oral presentation. For many years, the radioactive properties of the naturally occurring radionuclides have been used to determine their distributions in the marine environment and, more generally, to gain an understanding of the dynamic processes which control their behaviour in attaining these distributions. More recently the inputs from human activities of both natural and artificial (i.e. man-made) radionuclides have provided additional opportunities for the study of marine processes on local, regional and global scales. Because the sources of artificial radionuclides are often reasonably well defined in space and time, and because a wider range of elements is represented, new viewpoints for the study of processes have become available. Although it is outside the scope of this Symposium, it must be acknowledged that the radiological protection requirements for radioactive waste disposal prac tices to be based on a sound scientific understanding of radionuclide behaviour in the sea have also provided a very strong impetus for the studies.

Book Description
This book on Marine Radioactivity sets out to cover most of the aspects of marine radioactivity which have been the focus of scientific study in recent decades. The authors and their reviews divide into topic areas which have defined the field over its history. They cover the suite of natural radioisotopes which have been present in the oceans since their formation and quantitatively dominate the inventory of radioactivity in the oceans. Also addressed are the suite of artificial radionuclides introduced to the oceans as a consequence of the use of the atom for development of nuclear energy, nuclear weapons and various applications of nuclear science. The major source of these continues to derive from the global fallout of atmospheric tests of nuclear weapons in the 1950s and 1960s but also includes both planned and accidental releases of radioactivity from both civilian and military nuclear technology. The other division of the major study direction depends on whether the objective is to use the radionuclides as powerful tools to study oceanic processes, to describe and understand the ocean distribution of the various natural or artificial radionuclides or to assess the different radionuclides' impact on and pathways to man or marine organisms. The oceans cover 70% of the Earth's surface and thus contains a corresponding large share of the Earth's radioactivity. Marine Radioactivity covers topics of recent scientific study in this young field. It examines both natural radioactivity (radioactivity naturally present in oceans since their formation) and artificial radioactivity (radioactivity introduced by man and use of atomic and nuclear energy) with regard to possible effects on the global environment.

Book Description
This book documents the effects of natural hazards on coastal ecosystems in detail. The sea is an indispensable component of the Earth system, and human societies obtain many goods and services from the marine environment. Global warming threatens marine ecosystems through seawater temperature rise, acidification, sea-level rise and the increased frequency of severe storms. The repeated effects of tsunamis also have major impacts on coastal ecosystems. Increases in population and industry activities along the coast cause the degradation of coastal ecosystems through direct and indirect uses of the environment such as reclamation, overexploitation of bioresources, and pollution. Given these facts, we need to improve our understanding of the physical, chemical and biological mechanisms characterizing marine ecosystems, in order to better measure the effects of anthropogenic and natural impacts on the sea and its ecosystems. Equipped with a comprehensive understanding of the sea, including the effects of the main pressures on it, we will have a better idea of the future state of the sea based on several scenarios of global warming. The 16th France-Japan Symposium on Marine Science focused on using advances in oceanography to better understand the current status of the sea from physical, chemical, biological and ecological perspectives, including fishery sciences and integrated approaches.
