Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

Download or read book Coral Reef Remote Sensing written by James A. Goodman and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing stands as the defining technology in our ability to monitor coral reefs, as well as their biophysical properties and associated processes, at regional to global scales. With overwhelming evidence that much of Earth’s reefs are in decline, our need for large-scale, repeatable assessments of reefs has never been so great. Fortunately, the last two decades have seen a rapid expansion in the ability for remote sensing to map and monitor the coral reef ecosystem, its overlying water column, and surrounding environment. Remote sensing is now a fundamental tool for the mapping, monitoring and management of coral reef ecosystems. Remote sensing offers repeatable, quantitative assessments of habitat and environmental characteristics over spatially extensive areas. As the multi-disciplinary field of coral reef remote sensing continues to mature, results demonstrate that the techniques and capabilities continue to improve. New developments allow reef assessments and mapping to be performed with higher accuracy, across greater spatial areas, and with greater temporal frequency. The increased level of information that remote sensing now makes available also allows more complex scientific questions to be addressed. As defined for this book, remote sensing includes the vast array of geospatial data collected from land, water, ship, airborne and satellite platforms. The book is organized by technology, including: visible and infrared sensing using photographic, multispectral and hyperspectral instruments; active sensing using light detection and ranging (LiDAR); acoustic sensing using ship, autonomous underwater vehicle (AUV) and in-water platforms; and thermal and radar instruments. Emphasis and Audience This book serves multiple roles. It offers an overview of the current state-of-the-art technologies for reef mapping, provides detailed technical information for coral reef remote sensing specialists, imparts insight on the scientific questions that can be tackled using this technology, and also includes a foundation for those new to reef remote sensing. The individual sections of the book include introductory overviews of four main types of remotely sensed data used to study coral reefs, followed by specific examples demonstrating practical applications of the different technologies being discussed. Guidelines for selecting the most appropriate sensor for particular applications are provided, including an overview of how to utilize remote sensing data as an effective tool in science and management. The text is richly illustrated with examples of each sensing technology applied to a range of scientific, monitoring and management questions in reefs around the world. As such, the book is broadly accessible to a general audience, as well as students, managers, remote sensing specialists and anyone else working with coral reef ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: "Coral reefs throughout the world are subjected to a number of anthropogenic stressors. Some of the most pervasive of these are a result of climate change. Increasing sea surface temperature of the world's oceans is resulting in unprecedented, mass coral bleaching events wherein coral polyps expel their symbiotic zooxanthellae. Research also suggests these disturbances make coral reefs more susceptible to disease. Occurrences of mass bleaching and disease outbreaks prompted the U.S. National Oceanic and Atmospheric Administration (NOAA) to create Coral Reef Watch, a program that monitors many of the indicators of these events using satellites. Coral Reef Watch provides coral reef managers with near-realtime alerts of bleaching conditions as they develop. For Coral Reef Watch to adequately monitor the environmental conditions of coral reefs throughout the world, it is imperative that collaborations exist between coral reef ecosystem biologists, managers and remote sensing scientists. This technical report documents a workshop held in 2010 in which experts from around the world convened to share information and brainstorm about threats to coral reef ecosystems as a result of climate change. In addition, these experts discussed additional risks to coral reefs and potential remote sensing tools that could be developed in order to monitor the threats. This technical report provides substantive information on experts' current understandings of coral reef biology, best management practices for coral reef ecosystem management, and technical considerations for using environmental remote sensing to aid in these research and managerial pursuits"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are on track to become the first ecosystem actually eliminated from the planet. So says leading ecologist Peter F. Sale in this crash course on the state of the planet. Sale draws from his own extensive work on coral reefs, and from recent research by other ecologists, to explore the many ways we are changing the earth and to explain why it matters. Weaving into the narrative his own firsthand field experiences around the world, Sale brings ecology alive while giving a solid understanding of the science at work behind today’s pressing environmental issues. He delves into topics including overfishing, deforestation, biodiversity loss, use of fossil fuels, population growth, and climate change while discussing the real consequences of our growing ecological footprint. Most important, this passionately written book emphasizes that a gloom-and-doom scenario is not inevitable, and as Sale explores alternative paths, he considers the ways in which science can help us realize a better future.

Download or read book Encyclopedia of Modern Coral Reefs written by David Hopley and published by Springer Science & Business Media. This book was released on 2010-11-26 with total page 1226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.
