Available in PDF, EPUB and Kindle. Book excerpt: Many different aspects of the determination of dissolved oxygen by controlled potential coulometry were investigated to find a means of measuring the oxygen content of natural waters. Rapid sampling techniques, simplicity of operation, and rugged structural features were stressed. Cells were designed to operate by either internal electrolysis or external potential control. A type of steel flow cell of optimum geometry was designed, and measured oxygen in flow streams with 3% accuracy. Periodic sampling was found to be superior to flow analysis, and the flow cell operated by a method of periodic entrapment of sample yielded the most promising results. 0.2% reproducibility was obtained for samples which contained one to five ppm dissolved oxygen, and 1% reproducibility for samples below one ppm. The error in the analysis could not be distinguished from the two percent error in the Winkler titration which was used to determine the standards. Other sample entrapment cells of a different design and with different cathode materials were studied. Two vibrating electrode cells were investigated and found to give no better results than those cells which permit oxygen reduction in quiet solutions. Mercury, gold, platinum, nichrome, stainless steel, and brass were tested as cathode materials. The polarographic and coulometric behavior of dissolved oxygen reduced in cathodes of these materials is described. The investigation of mercury as a cathode material led to the development of an empirical method that relies on the rapid reduction of oxygen on a mercury-electrolyte interface. In one case, 0.5% reproducibility was obtained for individual samples determined at the rate of one every 15 seconds. The utility of these devices, although the current efficiency is low, is pointed out as their potential use as flow stream monitors. The entire work yielded information based on new approaches for the development of ocean-going devices which will measure dissolved oxygen concentrations by controlled potential coulometry to a better degree of accuracy than the existing methods. Design theory and cell construction is presented for devices that operate where rapidity of successive determinations is more important than absolute accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: In this thoroughly updated third edition, the authors provide a series of carefully designed and tested field and laboratory exercises that represent the full scope of limnology. In using the text, students will gain a solid foundation in this complex, multidisciplinary field of ecology as they explore the physical, chemical, and biological characteristics of standing and running waters. The book illustrates accepted standard methods as well as modern metabolic and experimental approaches and their research applications. Each exercise is preceded by an introductory section and concludes with questions for students as well as suggestions for further reading. As a textbook, this is a highly structured, concise presentation with a research-oriented approach that openly invites active participation by students.

Download or read book Respiration in Aquatic Ecosystems written by Paul del Giorgio and published by OUP Oxford. This book was released on 2005-01-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Respiration represents the major area of ignorance in our understanding of the global carbon cycle. In spite of its obvious ecological and biogeochemical importance, most oceanographic and limnological textbooks invariably deal with respiration only superficially and as an extension of production and other processes. The objective of this book is to fill this gap and to provide the first comprehensive review of respiration in the major aquatic systems of the biosphere. The introductory chapters review the general importance of respiration in aquatic systems, and deal with respiration within four key biological components of aquatic systems: bacteria, algae, heterotrophic protists, and zooplankton. The aim of this first part is to provide the backbone for the analysis and interpretation of ecosystem-level respiration in a variety of aquatic environments. The central chapters of the book review respiration in major aquatic ecosystems including freshwater wetlands, lakes and rivers, estuaries, coastal and open ocean and pelagic ecosystems, as well as respiration in suboxic environments. For each major ecosystem, the corresponding chapter provides a synthesis of methods used to assess respiration, outlines the existing information and data on respiration, discusses its regulation and link to biotic and abiotic factors, and finally provides regional and global estimates of the magnitude of respiration. The final chapter provides a general synthesis of the information and data provided in the different sections, and further attempts to place aquatic respiration within the context of the global carbon budget.

Available in PDF, EPUB and Kindle. Book excerpt: Extensively revised and updated, Handbook of Water Analysis, Third Edition provides current analytical techniques for detecting various compounds in water samples. Maintaining the detailed and accessible style of the previous editions, this third edition demonstrates water sampling and preservation methods by enumerating different ways to measure chemical and radiological characteristics. It gives step-by-step descriptions of separation, residue determination, and clean-up techniques. See What’s New in the Second Edition: Includes five new chapters covering ammonia, nitrates, nitrites, and petroleum hydrocarbons, as well as organoleptical and algal analysis methodology Compares older methods still frequently used with recently developed protocols, and examines future trends Features a new section regarding organoleptical analysis of water acknowledging that ultimately the consumers of drinking water have the final vote over its quality with respect to odor, flavor, and color The book covers the physical, chemical, and other relevant properties of various substances found in water. It then describes the sampling, cleanup, extraction, and derivatization procedures, and concludes with detection methods. Illustrated with procedure flow charts and schematics, the text includes numerous tables categorizing methods according to type of component, origin of the water sample, parameters and procedures used, and application range. With contributions from international experts, the book guides you through the entire scientific investigation starting with a sampling strategy designed to capture the real-world situation as closely as possible, and ending with an adequate chemometrical and statistical treatment of the acquired data. By organizing data into more than 300 tables, graphs, and charts, and supplementing the text with equations and illustrations, the editors distill a wealth of knowledge into a single accessible reference.
