Book Description
Humankind's use of zinc stretches back to antiquity, and it was a component in some of the earliest known alloy systems. Even though metallic zinc was not "discovered" in Europe until 1746 (by Marggral), zinc ores were used for making brass in biblical times, and an 87% zinc alloy was found in prehistoric ruins in Transylvania. Also, zinc (the metal) was produced in quantity in India as far back as the thirteenth century, well before it was recognized as being a separate element. The uses of zinc are manifold, ranging from galvanizing to die castings to electronics. It is a preferred anode material in high-energy-density batteries (e.g., Ni/Zn, Ag/Zn, ZnJair), so that its electrochemistry, particularly in alkaline media, has been extensively explored. In the passive state, zinc is photoelectrochemically active, with the passive film displaying n-type characteristics. For the same reason that zinc is considered to be an excellent battery anode, it has found extensive use as a sacrificial anode for the protection of ships and pipelines from corrosion. Indeed, aside from zinc's well-known attributes as an alloying element, its widespread use is principally due to its electrochemical properties, which include a well-placed position in the galvanic series for protecting iron and steel in natural aqueous environments and its reversible dissolution behavior in alkaline solutions.

Book Description
Marine ecosystems offer several benefits to human communities. To make sustainable use of these benefits, it is necessary to elucidate and conserve marine ecology, and strive to maintain a sustainable natural resource management program. For this reason, understanding the diversity and behavior of both macro-ecosystems and micro-ecosystems are crucial. Monitoring Artificial Materials and Microbes in Marine Ecosystems explores microbial roles and their interaction with artificial materials in marine environments. After starting with simple topics for beginners, chapters explore methods to detect microorganisms in marine ecosystems and interactions of marine organisms with artificial materials. The sequential progression into advanced topics makes it easier to understand how to solve the reduction in marine-ecosystem viability caused by adverse events. Readers are provided with useful information for rehabilitating marine environments to make them sustainable for communities. Topics are covered in 3 parts: Part 1 is an introductory guide to marine ecosystems and environmental monitoring assessment. Readers are introduced to coral reef ecosystems, algal blooms and the role of environmental monitoring services in maintaining and restoring the quality of marine environments. This is followed by examples of sustainable marine environment assessment.Part 2 provides information about methods to detect microorganisms (viruses and bacteria) and evaluate marine environments. This includes sample enrichment methods, electrochemical analysis, and single cell imaging techniques. The highly sensitive and specific techniques presented in the book, are applicable in a wide variety of situations.Part 3 is dedicated to interactions between artificial metallic materials and microorganisms in marine environments. Chapters in this section share results from several experiments conducted to separate microorganisms and biofilms from such environments. This book is intended primarily for marine ecologists, microbiologists, environmental engineers, and engineers associated with industrial projects. This book is also useful as a text for undergraduate and graduate level courses in marine biology, ecology, and microbiology.

Book Description
This manual describes the wide range of electromechanical, electrochemical and electro-optical transducers at the heart of current field-deployable ocean observing instruments. Their modes of operation, precision and accuracy are discussed in detail. Observing platforms ranging from the traditional to the most recently developed are described, as are the challenges of integrating instrument suits to individual platforms. Technical approaches are discussed to address environmental constraints on instrument and platform operation such as power sources, corrosion, biofouling and mechanical abrasion. Particular attention is also given to data generated by the networks of observing platforms that are typically integrated into value-added data visualization products, including numerical simulations or models. Readers will learn about acceptable data formats and representative model products. The last section of the book is devoted to the challenges of planning, deploying and maintaining coastal ocean observing systems. Readers will discover practical applications of ocean observations in diverse fields including natural resource conservation, commerce and recreation, safety and security, and climate change resiliency and adaptation. This volume will appeal to ocean engineers, oceanographers, commercial and recreational ocean data users, observing systems operators, and advanced undergraduate and graduate students in the field of ocean observing.
