Structure in the Sea: The Science, Technology and Effects of Purpose-Built Reefs and Related Surfaces

Description

Structure in the Sea: The Science, Technology and Effects of Purpose-Built Reefs and Related Surfaces provides a review of the history, development, status and emerging trends in research, technology and applications of artificial reef habitats and sea floor structures. The book helps readers understand, utilize and add to the research of modern reef deployment efforts, presenting a guide to equip stakeholders requiring technical foundations and best practices. Topics include materials, designs and construction methods, along with the ecology of these structures, including key aspects of the life history of plants and animals associated with artificial reefs. Rigorous research addressing ecological, economic and engineering questions, coupled with the innovative deployment of structures worldwide by diverse stakeholders, have created a synergy that makes the book a valuable synthesis and analysis for this growing subject. Thus, its broad audience includes marine (coastal and ocean) environmental sciences, including aquatic ecologists, those working in ocean sustainability and conservation, benthic habitat and coral reef restoration practitioners, and more.
