Download or read book Coral Reefs of the USA written by Bernhard M. Riegl and published by Springer Science & Business Media. This book was released on 2008-03-21 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral Reefs of the USA provides a complete overview of the present status of knowledge regarding all coral reef areas within the USA and its territories. It is written by the most experienced authorities in their fields and geographic areas. Stretching from the Caribbean to the western Pacific, the coral reefs of the USA span extensive geographic and biotic diversity, occur in a wide variety of geomorphological settings, and provide a representative cross-section of Holocene reef-building. This book will therefore be of broad general interest. For the first time, complete scholarly reviews are given for the geology, geomorphology and the biology of reefs encompassing a vast area stretching from the Mariana Islands in the west, Samoa in the south, Hawaii in the north and the Virgin Islands in the east. This book is not a status report, but will provide up-to-date information about stressors and the biotic responses of the reefs, as well as the geological explanations why these reefs exist in the first place. It will be an invaluable baseline-reference for all those who are engaged in research or management of these coral reefs or to those who simply enjoy being well-informed about one of the most iconic ecosystems of the USA.

This book was released on 2017 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the US Virgin Islands (USVI), land-based (terrigenous) sedimentation has been identified as a major cause of coral stress. Development, such as the building of unpaved roads in steep coastal watersheds, has increased sediment yields and marine terrigenous sedimentation by up to an order of magnitude above background levels. When activated during storm events, ephemeral streams transport sediment from the watershed to coastal waters. Once deposited on the seafloor, resuspension of benthic sediments can further increase turbidity and deposition. However, isolating the relative contributions of runoff and resuspension to turbidity and deposition using conventional sediment trap monitoring has been challenging. Here we describe the spatial and temporal variability of marine sediment dynamics in response to runoff and resuspension events in St. John, USVI. Between late July 2013 and January 2014, nephelometers were deployed at three reef and five shoreline sites next to ephemeral stream outfalls equipped with a water level sensor (10-min resolution) and peak crest gauges (~13-day resolution). At each instrument site, benthic sediment samples were collected every ~26 days. While runoff events resulted in high-magnitude spikes in turbidity and deposition, which were up to 900 and 17,000 times background, respectively, they were short-lived (hours). Resuspension-induced spikes in turbidity and deposition were lower in magnitude but of longer duration (days-weeks), particularly at sites with finer-grained benthic sediments, and were associated with increased wave height during low tides. While the relative contribution of runoff and resuspension to turbidity and deposition were spatially variable between our study sites, resuspension contributed at least 7 times more to turbidity and 3 times more to deposition than runoff during the 2013 rainy season at one of our coastal marine monitoring sites. Though previous studies have measured marine sedimentation over months-centuries in St. John, no studies have monitored turbidity or the relative contributions to turbidity and deposition from runoff and resuspension at the time scale of minutes-days. Understanding the relative contribution of runoff vs. resuspension to marine turbidity and deposition is important to effectively manage land-based sedimentation, marine development, as well as evaluate the effectiveness of watershed restoration programs which aim to reduce marine terrigenous sedimentation.

This book was released on 2015 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Caribbean, sedimentation has been identified as a serious threat to coral reef communities. Although land-based sediment delivery to coastal waters harboring coral reefs occurs under natural conditions, human activities in the watersheds above reefs increases the erosion and delivery of terrigenous sediment to the reefs. Delivery of terrigenous sediment into marine areas below developed watersheds affects sedimentation rates, alters the composition and texture of sediments that are suspended in the water column, and/or sediments that are deposited on the sea floor and on corals. St. John, U.S. Virgin Islands is an ideal location to study the effects of rainfall and human development on sedimentation on coral reefs. From a management perspective, there is a need on St. John for studies that examine how watershed development and watershed restoration activities affect marine sedimentation. The outcomes of this study have shown that sediment traps are an effective way to monitor general temporal and spatial patterns in terrigenous sedimentation. This study is the first marine sediment trap study to capture the natural variability in storms, rainfall, and wave activity over a study period longer than two years that also monitored distinct near shore and offshore areas below both developed and minimally developed watersheds simultaneously. Monitoring simultaneously across distinct areas over a long, 5-year study period made it possible to examine the relationship between terrigenous sedimentation, rainfall and wave activity statistically, and identify areas most likely to be subjected to the greatest sediment-related coral stress. The results of this study have generated potentially useful data related to watershed land management in tropical, coastal areas and will help inform future studies that will assess the effect of watershed restoration efforts on terrigenous sediment delivery to marine areas harboring coral reefs.
