Book Description
In 2008 an initial benthic habitat map was completed by the contractor Avineon, Inc. The National Park Service South Florida / Caribbean Network (SFCN) conducted an accuracy assessment of the map and found the overall habitat identification to be acceptable. However, upon further inspection, the soft-bottom habitat classifications displayed a relatively high level of accuracy, while the hard-bottom habitats were below an acceptable level. With the acquisition of new higher resolution side scan sonar data and 2054 field data points from multiple sources, the 2008 map was revised and improved by utilizing these new data sets to produce the 2010 Dry Tortugas benthic habitat map. The 2010 Dry Tortugas benthic habitat map was developed using 13 mapping classes and 1709 polygons totaling an area of 26,229 hectares. All "Unknown" areas (10,444 hectares) in the 2008 map were identified, the line work for the hard-bottom areas was fine-tuned and a mapping layer was developed showing those areas which have a higher potential for fish and benthic biodiversity. In addition, a final bathymetry layer for the park was developed by merging the existing light detection and ranging (LiDAR) and newly acquired side scan sonar/bathymetry data. The current management plan for the Dry Tortugas National Park (DRTO) marine areas focuses much of its effort on the Research Natural Area (RNA). The intensive amount of research effort placed on the RNA has also accomplished the research needed for the rest of DRTO because current research and monitoring efforts are split equally between areas of the DRTO that fall within and outside the RNA to make for a balanced comparative study design. In February of 2007, National Park Service (NPS) and Florida Fish and Wildlife Conservation Commission (FWC) developed a science plan to assess conservation effectiveness for the RNA in conjunction with the rest of DRTO and the two nearby existing marine reserves. The implementation of the science plan has been accomplished through collaboration and cooperation of federal and state agencies, academic scientists, and NPS. The new benthic habitat map and corresponding products will help in showing what types of marine habitats are located in the Dry Tortugas National Park and provide the ability to track whether management interventions are effectively protecting the environment and associated resources.

Book Description
The National Park Service Vegetation Mapping Inventory Program (NPS-VMP) funded the NPS South Florida / Caribbean Network (SFCN) to map the seven islands of Dry Tortugas National Park in 2009. The vegetation map of Dry Tortugas National Park was created by in-field polygon delineation instead of the more common photointerpretation of aerial imagery. Using the Trimble GeoXT GPS device in the field allowed the production of a finely detailed vegetation map (vegetation census) for Loggerhead Key, Garden Key, Bush Key, East Key, Long Key, Middle Key, and Hospital Key. The Dry Tortugas vegetation maps were made using the Universal Transverse Mercator (UTM) zone 17 North coordinate system and the North American Datum of 1983 (NAD 83) with a minimum mapping unit of 25 m2. The SFCN developed a vegetation classification in congruence with the vegetation map of Dry Tortugas National Park. The Dry Tortugas vegetation classification conforms to the Rutchey et al. (2006) South Florida Vegetation Classification System coupled with the vegetation communities unique to the Dry Tortugas.

Book Description
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.

Book Description
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.

Book Description
This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.
