Kurzbeschreibung
An essential companion to the acclaimed volume, Biofouling, Biofouling Methods provides the single most comprehensive collection available of tried and trusted methods and practical how-to-do-it information. Edited by the foremost international experts in biofouling, this "cook book" full of practical recipes encompasses the full diversity of the field, providing aquatic biologists, ecologists, environmental scientists, chemists, and medical researchers guidance in how to measure microbial fouling, to the data requirements for biocide registration, and everything in between.
Biofouling Methods provides a "cook book" for both established workers and those new to the field. The methods included in this important new book range from tried and tested techniques to those at the cutting edge, encompassing the full diversity of this multidisciplinary field.
The book covers methods for microbial and macrofouling, coatings and biocides, and ranges from methods for fundamental studies to methods relevant for industrial applications. There is an emphasis on answering questions and each chapter provides technical methods and problem-solving hints and tips.
Bringing together a wealth of international contributions and edited by three internationally known and respected experts in the subject Biofouling Methods is the essential methodology reference in the field for all those working in the antifouling industry including those involved in formulation of antifouling products such as paints and other coatings. Aquatic biologists, ecologists, environmental scientists and lawyers, marine engineers, aquaculture personnel, chemists, and medical researchers will all find much of interest within this book. All universities and research establishments where these subjects are studied and taught should have copies of this important work on their shelves.
