As we discover more about the role of the ocean in global changes and identify the effects of global change on the ocean, understanding its chemical composition and processes becomes increasingly paramount. However, understanding these processes requires a wide range of measurements in the vast ocean, from the sea surface to deep-ocean trenches, from the tropics to the poles. Practical Guidelines for the Analysis of Seawater provides a common analytical basis for generating quality-assured and reliable data on chemical parameters in the ocean. A source of practical know-how, the book covers sampling and storage, analytical methodology, and guidelines and procedures for quality assurance. It presents analytical methods with the step-by-step procedures that help practitioners implement these methods successfully into the laboratory, making them instantly applicable without consulting further literature. The book also contains essential information for developing or improving quality control and quality assurance programs in the laboratory. It includes the availability and measurement of standard reference materials, blank estimation and correction, control of recoveries, and statistical evaluation of quality assurance data. Analytical chemistry is a very active and fast moving area. Despite the development of innovative new analytical techniques for chemical trace element research, obtaining reliable data at ultra-trace levels remains a formidable challenge. A complete and practical guide, this book delineates proven methods that consistently yield reproducible data in routine work.

Applications of radioactive and stable isotopes have revolutionized our understanding of the Earth and near-earth surface processes. The utility of the isotopes are ever-increasing and our sole focus is to bring out the applications of these isotopes as tracers and chronometers to a wider audience so that they can be used as powerful tools to solve environmental problems. New developments in this field remain mostly in peer-reviewed journal articles and hence our goal is to synthesize these findings for easy reference for students, faculty, regulators in governmental and non-governmental agencies, and environmental companies. While this volume maintains its rigor in terms of its depth of knowledge and quantitative information, it contains the breadth needed for wide variety problems and applications in the environmental sciences. This volume presents all of the newer and older applications of isotopes pertaining to the environmental problems in one place that is readily accessible to readers. This book not only has the depth and rigor that is needed for academia, but it has the breadth and case studies to illustrate the utility of the isotopes in a wide variety of environments (atmosphere, oceans, lakes, rivers and streams, terrestrial environments, and sub-surface environments) and serves a large audience, from students and researchers, regulators in federal, state and local governments, and environmental companies.

A substantial increase in the number of studies using the optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical properties in estuaries and the coastal and open ocean has occurred during the last decade. We are making progress on finding the actual chemical compounds or phenomena responsible for DOM’s optical properties. Ultrahigh resolution mass spectrometry, in particular, has made important progress in making the key connections between optics and chemistry. But serious questions remain and the last major special issue on DOM optics and chemistry occurred nearly 10 years ago. Controversies remain from the non-specific optical properties of DOM that are not linked to discrete sources, and sometimes provide conflicting information. The use of optics, which is relatively easier to employ in synoptic and high resolution sampling to determine chemistry, is a critical connection to make and can lead to major advances in our understanding of organic matter cycling in all aquatic ecosystems. The contentions and controversies raised by our poor understanding of the linkages between optics and chemistry of DOM are bottlenecks that need to be addressed and overcome.

Wide- scale chemical monitoring programmes are required by international conventions and European Union policies such as the Water Framework Directive (2000/60/EC) and the new EU Marine Strategy Framework Directive (MSFD). This entails all waters, including transitional and coastal waters, sediments and biota. The final volume in the Water Quality Measurement Serieshighlights policy frameworks and analytical trends with an emphasis on laboratory methods and quality control. Within this comprehensive text, the following sections are included: Setting the Scene; monitoring of pollutants Policy Settings; international conventions and EU marine strategy Marine monitored parameters; trace elements, chemical species, organic micropollutants, and nutrients Types of monitoring; classical chemical monitoring, biomonitoring and in-situ methods Quality assurance; certified reference materials for marine monitoring Research and developments; the role of sediments in coastal monitoring, and passive sampling technologies Chemical Marine Monitoring: Policy Framework and Analytical Trends is intended for postgraduates and researchers working in analytical chemistry and its application to environmental and health analyses. Those interested in developing new methods and materials in relation to drinking water regulations with also find this book beneficial.

Microorganisms (bacteria, archaea, microeukaryotes) in marine environments secrete a diverse array of exopolymeric substances that facilitate attachment to surfaces, the formation of organic colloids and larger aggregations of cells (marine snow), and that can influence many ocean, as well as global, processes. The aim of this Research Topic is to highlight recent advances in the sources, chemistry and function of these microbial-produced macromolecules. We encouraged original research and reviews on exopolymeric substances, from their sources, chemico-physiological properties, functions and ecosystem effects, and including their role in the Gulf of Mexico following the Deepwater Horizon oil spill disaster.

This comprehensive work stems from the activities of SCOR Working Group 78 (Determination of Photosynthetic Pigments in Seawater) established in 1985. It brings together in one volume all the oceanographer needs to measure and identify pigments as well as to select the most appropriate methods and ensure the best analytical quality control.
