Biophysics of the Surface Microlayer of Aquatic Ecosystems introduces the concept of the surface film, or microlayer, of natural water bodies as a specific biophysical environment. The book investigates the hydrophysics, physical chemistry, hydrochemistry and hydrobiology of the surface microlayer in detail. Biophysics of the Surface Microlayer of Aquatic Ecosystems fills the existing gaps in the literature that exist between studies of the surface film by hydrophysicists, hydrochemists and hydrobiologists, by introducing essential physical surface film phenomena to biologists, and biological surface film phenomena to physicists. This book is thus a valuable and unique reference work for oceanologists and limnologists around the world. Contents Introduction: Surface films and microlayers Thermophysics of the surface film of water Aeration through the surface film Films of surfactants at the water surface Hydrochemistry of the surface microlayer of natural water bodies Neustonology Conclusion
This volume represents a practical survey of current understanding of chemical contamination of the Mediterranean Sea. Beginning with an overview of the general physical and socio-economic context, the author reviews the exploration of processes governing the fate of chemicals, assesses the budget of both inorganic and organic contaminants, and describes new tools for studying the impact of pollution on the Mediterranean.
Inland aquatic habitats occur world-wide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas; from streams and creeks to rolling rivers. Vital for biological diversity, ecosystem function and as resources for human life, commerce and leisure, inland waters are a vital component of life on Earth. The Encyclopedia of Inland Waters describes and explains all the basic features of the subject, from water chemistry and physics, to the biology of aquatic creatures and the complex function and balance of aquatic ecosystems of varying size and complexity. Used and abused as an essential resource, it is vital that we understand and manage them as much as we appreciate and enjoy them. This extraordinary reference brings together the very best research to provide the basic and advanced information necessary for scientists to understand these ecosystems – and for water resource managers and consultants to manage and protect them for future generations.

The agricultural industry is dealing with enormous challenges across the globe, including the limited availability of arable lands and fresh water, as well as the effect of climate change. Machinery plays a crucial role in agriculture and farming systems, in order to feed the world’s growing population. In the last decade, we have witnessed major advances in agricultural machinery and technologies, particularly as manufacturers and researchers develop and apply various novel ways of automation as well as the data and information gathering and analyzing capabilities of their machinery. This book presents the state-of-the-art information on the important innovations in the agricultural and horticultural industry. It reviews and presents different novel technologies and implementation of these technologies to optimize farming processes and food production. There are four sections, each addressing a specific area of development. Section I discusses the recent development of farm machinery and technology. Section II focuses on water and irrigation engineering. Section III covers harvesting and post-harvest technology. Section IV describes computer modelling and simulation. Each section highlights current industry trends and latest research progress. This book is ideal for those working in or are associated with the fields of agriculture, agri-food chain and technology development and promotion.
A groundbreaking, witty, and eloquent exploration of slime that will leave you appreciating the nebulous and neglected sticky stuff that covers our world, inside and out. Slime. The very word seems to ooze oily menace, conjuring up a variety of unpleasant associations: mucous, toxins, reptiles, pollutants, and other unsavory viscous semi-liquid substances. Yet without slime, the natural world would be completely unrecognizable; in fact, life itself as we know it would be impossible In this deft and fascinating book, journalist Susanne Wedlich takes us on a tour of all things slimy, from the most unctuous of science fiction monsters to the biochemical compounds that are the very building blocks of life. Along the way she shows us what slime really means, and why slime is not something to fear, but rather something to ... embrace.
This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!
The rationale for publishing a second edition of this monograph is that this area of research continues to show remarkable advancement. The new generation of synthetic aperture radar satellites has provided unprecedented spatial resolution of sea surface features. In addition, satellites to measure sea surface salinity have been launched. Computational fluid dynamics models open new opportunities in understanding the processes in the near-surface layer of the ocean and their visibility from space. Passive acoustic methods for monitoring short surface waves have significantly progressed. Of importance for climate research, processes in the near-surface layer of the ocean contribute to errors in satellite estimates of sea surface temperature trends. Due to growing applications of near-surface science, it is anticipated that more students will be trained in this area of research. Therefore this second edition of the monograph is closer to a textbook format.
