This book was released on 2014 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Baseline mapping and quantitative assessment data are required prior to future permitted or un-permitted impacts in order to determine the pre-existing state of the benthic resources; therefore, it is imperative that these data be collected on the ecologically sensitive and economically valuable shallow-water coral reef habitats in southeast Florida. In southeast Florida, the nearshore reef habitats are most vulnerable to coastal construction activities and other anthropogenic impacts, therefore these habitats were the focus for this study. The study goals were to provide a spatially appropriate map of increased resolution and a regional quantitative characterization of nearshore benthic resources to evaluate differences in benthic communities between habitats and with latitude for the southeast Florida region of the Florida Reef Tract. This study is a snapshot habitat characterization providing the current status of shallow-water coral reef community composition. Additionally, these data can be used to reduce un-permitted impacts by informing marine zoning efforts and aid in the creation of new no-anchor zones"--Executive summary.

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.
Download or read book Mesophotic Coral Ecosystems written by Yossi Loya and published by Springer. This book was released on 2019-06-21 with total page 1003 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes what is known about mesophotic coral ecosystems (MCEs) geographically and by major taxa. MCEs are characterized by light-dependent corals and associated communities typically found at depths ranging from 30-40 m. and extending to over 150 m. in tropical and subtropical ecosystems. They are populated with organisms typically associated with shallow coral reefs, such as macroalgae, corals, sponges, and fishes, as well as specialist species unique to mesophotic depths. During the past decade, there has been an increasing scientific and management interest in MCEs expressed by the exponential increase in the number of publications studying this unique environment. Despite their close proximity to well-studied shallow reefs, and the growing evidence of their importance, our scientific knowledge of MCEs is still in its early stages. The topics covered in the book include: regional variation in MCEs; similarities and differences between mesophotic and shallow reef taxa, biotic and abiotic conditions, biodiversity, ecology, geomorphology, and geology; potential connectivity between MCEs and shallow reefs; MCE disturbances, conservation, and management challenges; and new technologies, key research questions/knowledge gaps, priorities, and future directions in MCE research.

Available in PDF, EPUB and Kindle. Book excerpt: "This Southern Florida Shallow-water Coral Ecosystem Mapping Implementation Plan (MIP) presents a framework for the development of shallow-water ( -0-40 m; 0-22 fm) benthic habitat and bathymetric maps of critical areas in southern Florida. It also discusses the need to develop moderate-depth ( -40-200 m; 22 -109 fm) bathymetric maps for all of Florida. The plan has been developed with extensive input from universities, state regulatory and management agencies, federal agencies, and non-governmental organizations involved in the conservation and management of Florida's coral ecosystems. A list of organizations that provided input to the development of this MIP is provided in Appendix 1. Appendix 3 briefly presents the outcomes of two meetings where the development of this MIP was discussed. This MIP has been developed to complement the Coral Reef Mapping Implementation Plan (2nd Draft) released in 1999 by the U.S. Coral Reef Task Force's Mapping and Information Synthesis Working Group. That plan focused on mapping the U.S.'s shallow-water (then defined as
Download or read book Final Report to the National Oceanic and Atmospheric Administration Coral Reef Conservation Program written by Felicia C. Coleman and published by . This book was released on 2004 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intent of this study was to assess the current status of the biotic communities of the Florida Middle Grounds, an area off the West Florida Shelf in the northeastern Gulf of Mexico. We compared our data with that of other similar studies done 25 to 30 years ago in the 1970s to determine whether the area has experienced significant change in benthic cover and associated fish fauna. The Middle Grounds is unique because it represents the northernmost extent of midshelf octocoral communities in North America. and is the confluence of at least two faunal components, Caribbean and Carolinian. This study was not intended as a description of community dynamics, but only as a 'snapshot' of present conditions. We found no indications of coral die-off nor of other diseases in the benthic community, but there was an obvious paucity of economically important fish species which we attribute to fishing. The Florida Middle Grounds should be monitored at least decadally to assess the potential impacts of global warming, coastal development, offshore oil and gas exploration, and ocean dumping--all of which can have profound influences even in remote areas and affect the quality of the associated communities.

Download or read book Characterization of Fish Assemblages on an Upper Mesophotic Reef in South Florida Using a Commercial Grade Mini ROV written by Sydney L. Panzarino and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesophotic coral ecosystems, or MCEs, are coral ecosystems at approximately 30-150m depths and represent the transitional zone where benthic organisms rely less on photosynthesis and more on filter-feeding or other feeding habits in order to sustain themselves. Fish assemblages in MCEs have been poorly studied and may possibly provide a connection to shallow water reefs (SWRs). Mesophotic reef fish communities from 32-37 m depths were assessed using video footage recorded by a remotely operated vehicle (ROV). Video transects were performed at three locations: unburied areas north and south of Port Everglades, as well as an area which experienced burial from dredging material produced during the creation of Port Everglades at the turn of the 20th century.The results of this research are significant as they have added to a large data gap which existed concerning local MCE fish communities. Results showed evidence of shallow water reef overlap to the upper mesohphotic zone as well as novelties regarding ROV sampling. Additionally, baited versus un-baited ROV transects showed no significant difference in fish assemblages. Particularly, this information provides insight into the connectivity of MCEs to SWRs, as well as long term differences of fish assemblages in areas buried by dredge materials. Local MCE administrators may now utilize this data to more efficiently manage these deeper environments which have previously relied only on SWR data.
Download or read book Classification Scheme for Mapping the Shallow water Coral Ecosystems of Southern Florida written by and published by . This book was released on 2007 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A hierarchical classification scheme is being developed to define and delineate the benthic habitats associated with southern Florida's shallow-water (generally, less than 30 m depth) coral ecosystems. The hierarchical scheme allows users to expand or collapse the thematic detail of the resulting map to suit their needs. This is an important aspect of the scheme as it provides a 'common language' to compare and contrast digital maps derived from various remote sensing platforms. The ability to apply any component of this scheme is dependent on being able to identify and delineate a given feature in remotely sensed imagery and assess the accuracy of the resulting benthic habitat map. Furthermore, the hierarchical structure of the scheme enables users to add habitat categories to the resulting GIS-based maps"--Introduction.

Download or read book Survey of Coral and Fish Assemblages on Pulley Ridge SW Florida written by Stacey Lyn Harter and published by . This book was released on 2008 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The coral reef community covering Pulley Ridge is the deepest known light-dependent coral reef on the US continental shelf. Located off the southwest coast of Florida, the ridge is a drowned barrier island colonized by several species of hermatypic coral and a fish community comprised of both deep and shallow water species. Pulley Ridge has been designated a habitat area of particular concern (HAPC) due to the presence of these coral formations. The Gulf of Mexico Fishery Management Council (GMFMC) has expressed concerns over ongoing damage to the habitat by fishing operations and is considering additional protective measures. The primary goals of this project were to determine the extent of scleractinian corals, especially Agaricia spp. as it is the most abundant hermatypic coral on the ridge, and examine fish diversity on the Pulley Ridge formation. The principle gear used to examine habitat and the fish community was a remotely operated vehicle (ROV), while the secondary gear used was a stationary camera array. Cruises in August 2007 and April 2008 resulted in 19 ROV dives and 12 camera array drops. There was a distinct difference in habitat between northern and southern Pulley Ridge, which resulted in distinct fish community compositions between the areas as well. Habitat to the north of the HAPC was characterized as one of three habitats: sand, pavement, and low relief outcrops, the latter two displaying varying degrees of live bottom coverage including several species of sessile and encrusting invertebrates and algae. The habitat in the southern area of Pulley Ridge was characterized as rock rubble with varying coverage of algae, coralline algae, hermatypic corals, solitary and encrusting sponges, octocorals, and antipatharians. Fish diversity was highest in southern Pulley Ridge on the rock rubble habitat. Sand tilefish (Malacanthus plumieri) mounds and red grouper (Epinephelus morio) pits were common in southern Pulley Ridge. Agaricia spp. was only observed in the southern portion of Pulley Ridge both inside and outside the HAPC in depths between 61.3 and 89.0 m. Results from this study will be valuable to the GMFMC in making future effective management decisions"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Nearshore hardbottom reefs of Florida’s east coast are used by over 1100 species of fishes, invertebrates, algae, and sea turtles. These rocky reefs support reproduction, settlement, and habitat use, and are energy sources and sinks. They are also buried by beach renourishment projects in which artificial reefs are used for mitigation. This comprehensive book is for research scientists and agency personnel, yet accessible to interested laypersons including beachfront residents and water-users. An unprecedented collection of research information and often stunning color photographs are assembled including over 1250 technical citations and 127 figures. These shallow reefs are part of a mosaic of coastal shelf habitats including estuarine seagrasses and mangroves, and offshore coral reefs. These hardbottom habitats are federally designated as Essential Fish Habitats - Habitats of Particular Concern and are important feeding areas for federally-protected sea turtles. Organismal and assemblage responses to natural and man-made disturbances, including climate change, are examined in the context of new research and management opportunities for east Florida’s islands in the sand.
