Book Description
Measurements of variable chlorophyll fluorescence have revolutionised global research of photosynthetic bacteria, algae and plants and in turn assessment of the status of aquatic ecosystems, a success that has partly been facilitated by the widespread commercialisation of a suite of chlorophyll fluorometers designed for almost every application in lakes, rivers and oceans. Numerous publications have been produced as researchers and assessors have simultaneously sought to optimise protocols and practices for key organisms or water bodies; however, such parallel efforts have led to difficulties in reconciling processes and patterns across the aquatic sciences. This book follows on from the first international conference on “chlorophyll fluorescence in the aquatic sciences” (AQUAFLUO 2007): to bridge the gaps between the concept, measurement and application of chlorophyll fluorescence through the synthesis and integration of current knowledge from leading researchers and assessors as well as instrument manufacturers.

Book Description
Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

Book Description
Chemical Deicers and the Environment provides a complete discussion of chemical deicer technology and history in the United States and Canada. The book describes engineering applications, maintenance procedures, economic evaluations, in addition to environmental problems and concerns relative to the use of chemical deicing. It also provides a technical appraisal of the latest technology to stimulate further research and discussion directed toward achieving a more integrated approach for the application of new deicers that will protect motor vehicles, highways and infrastructures, and the environment. Chemical Deicers and the Environment will be a useful reference volume for scientists, legislators, transportation engineers, environmentalists, consultants, and concerned individuals interested in learning about the economic and environmental advantages and disadvantages of today's chemical deicers.

Book Description
​This book examines the impacts of radionuclides released from the 2011 Fukushima Daiichi Nuclear Power Plant (FDNPP) accident on inland aquatic environments. The focus is on the dynamics of radiocesium in inland aquatic environments. The book comprises three parts: migration behavior of radiocesium in river and lake environment, accumulation of radiocesium into organisms in freshwater, and integrated environmental analysis in a lake system and a forest-freshwater system. Many studies on the dynamics of radionuclides have been published after the FDNPP accident, especially of radiocesium (134Cs 137Cs) in land and marine environment. The key features of this book are the new data of freshwater environment including transport of radionuclides in river and lake watershed, and accumulation of radiocesium in freshwater fishes and insects. Another feature of this book is that it summarizes the dataset of a model lake, Lake Akagi-Onuma, from geochemical and biological approaches. Readers will learn the actual dispersion behavior of radionuclides released from the Fukushima accident and their impacts on freshwater environments since the accident in 2011. The book presents valuable information for assessing the impacts of the FDNPP accident on ecosystem and human health, which are also useful in developing countermeasures for similar accidents and environmental contaminations.

Book Description
Epoch-making progress in meteorology and atmospheric science has always been hastened by the development of advanced observational technologies, in particular, radar technology. This technology depends on a wide range of sciences involving diverse disciplines, from electrical engineering and electronics to computer sciences and atmospheric physics. Meteorological radar and atmospheric radar each has a different history and has been developed independently. Particular radar activities have been conducted within their own communities. Although the technology of these radars draws upon many common fields, until now the interrelatedness and interdisciplinary nature of the research fields have not been consistently discussed in one volume containing fundamental theories, observational methods, and results. This book is by two authors who, with long careers in the two fields, one in academia and the other in industry, are ideal partners for writing on the comprehensive science and technology of radars for meteorological and atmospheric observations.

Book Description
The ROV Manual: A User Guide for Observation-Class Remotely Operated Vehicles is the first manual to provide a basic ""How To"" for using small observation-class ROVs for surveying, inspection and research procedures. It serves as a user guide that offers complete training and information about ROV operations for technicians, underwater activities enthusiasts, and engineers working offshore. The book focuses on the observation-class ROV and underwater uses for industrial, recreational, commercial, and scientific studies. It provides information about marine robotics and navigation tools used to obtain mission results and data faster and more efficiently. This manual also covers two common denominators: the technology and its application. It introduces the basic technologies needed and their relationship to specific requirements; and it helps identify the equipment essential for a cost-effective and efficient operation. This user guide can be invaluable in marine research and surveying, crime investigations, harbor security, military and coast guarding, commercial boating, diving and fishing, nuclear energy and hydroelectric inspection, and ROV courses in marine and petroleum engineering. * The first book to focus on observation class ROV (Remotely Operated Vehicle) underwater deployment in real conditions for industrial, commercial, scientific and recreational tasks * A complete user guide to ROV operation with basic information on underwater robotics and navigation equipment to obtain mission results quickly and efficiently * Ideal for anyone involved with ROVs complete with self-learning questions and answers

Book Description
Written by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.
