The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

A number of trends and forces are converging to require change in the National Oceanic and Atmospheric Administration's (NOAA) nautical charting mission. The most salient among these are changes in customer requirements, with a growing demand for customized and digital nautical information products; a changing customer base that encompasses uses of nautical charts in conjunction with coastal management, regulation, and development activities; and advances in technologies both for acquiring survey data and for structuring, displaying, analyzing, and disseminating nautical information. This volume assesses the needs of users of nautical information; reviews existing and emerging technologies; and examines major issues associated with information acquisition, chart preparation, and dissemination. The book addresses user requirements for improved nautical chart products, as well as technical and programmatic issues relating to the need for and provision of nautical information.
