One of the goals of the USGS Coastal and Marine Geology Program is a national assessment of coastal change hazards. One such hazard is extreme storms and hurricanes as they provide a powerful force that generates dangerous waves and currents capable of moving large amounts of sand, destroying buildings and infrastructure, and reshaping our nation's coastline. Our research focuses on understanding the magnitude and variability of the impacts of hurricanes and extreme storms on the sandy beaches of the United States. The overall objective is to improve the capability to predict coastal change that results from severe storms. Such a capability will facilitate locating buildings, infrastructure, and evacuation routes away from severe coastal change hazards.
A Coastal Classification Map describing local geomorphic features is the first step toward determining the hazard vulnerability of an area. The National Assessment of Coastal Change Project's Coastal Classification Maps present ground conditions such as beach width, dune elevations, overwash potential, and density of development. In order to complete a hazard vulnerability assessment, that information must be integrated with other information, such as prior storm impacts and beach stability. The Coastal Classification Maps provide much of the basic information for such an assessment and represent a critical component of a storm-impact forecasting capability.
The objective of the project is to translate Everglades National Park aerial photo archives into digital format.
This project has created new capabilities for the baseline inventorying and monitoring of natural and cultural resources within National Seashores. Methods for monitoring barrier island change, land cover distributions, benthic ecosystems, and man-made structures have been devised. These algorithms are being combined with standardized data reduction and documentation procedures to create software packages that generate GIS-ready digital information products relevant to Park needs. The LaserMap system has been developed for the processing of NASA ATM surveys and is in use to fulfill the needs of the NPS Vital Signs Program. Also, a separate software module within the Airborne Lidar Processing System (ALPS) supports the interactive browsing of GPS-referenced digital aerial photography data sets that are acquired concurrent with NASA ATM and EAARL lidar surveys. Information on these capabilities is provided through USGS Open File Reports, conference proceedings papers, and scientific journals. A stream of experimental GIS-ready spatial information products is being distributed to resource managers at several NPS coastal Parks

This ecological synthesis project will integrate the numerous autecological floral and faunal studies which have been conducted over the years within the SICS area. Particular attention will be paid to defining and constructing longterm datasets which will have the potential to measure changes and be integrated with the hydrodynamic models currently being developed. These datasets, when fully developed, will be used to assess change within the study area as related to past management practices and to guide the development of future environmental management scenarios as related to the Central and South Florida Project Review.
Mucus samples were collected from healthy corals in the Florida Keys and used to isolate coral-associated bacteria. These bacteria were tested to determine if native bacteria living in coral mucus are capable of providing an anti-bacterial defense against 'outsider' microbes to help protect the coral.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat. It will continue to improve our understanding of processes that control these hazards, and will allow researchers to determine the probability of coastal change locally, regionally, and nationally. The National Assessment will deliver these data and assessment findings about coastal vulnerability to coastal managers, other researchers, and the general public.
Beach erosion is a chronic problem along most open-ocean shores of the United States. As coastal populations continue to grow, and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present shoreline changes. There is also need for a comprehensive analysis of shoreline movement that is regionally consistent. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii. A primary goal of this work is to develop standardized methods for mapping and analyzing shoreline movement so that internally consistent updates can periodically be made to record shoreline erosion and accretion.

Pulley Ridge is a 100+ km-long series of N-S trending, drowned, barrier islands on the southwest Florida Shelf approximately 250 km west of Cape Sable, Florida. The ridge has been mapped using multibeam bathymetry, submarines and remotely operated vehicles, and a variety of geophysical tools. The ridge is a subtle feature about 5 km across with less than 10 m of relief. The shallowest parts of the ridge are about 60 m deep. Surprisingly at this depth, the southern portion of the ridge hosts an unusual variety of zooxanthellate scleractinian corals, green, red and brown macro algae, and typically shallow-water tropical fishes.

A holistic, multi-disciplinary approach is needed to address the research needs in the basin and estuary and to provide supportive data for meeting management objectives of the entire ecosystem. The USGS is well situated to focus on the larger concerns of the basin and estuary by addressing specific research questions linking water supply and quality to ecosystem function and health across county and state boundaries. We are interested in developing a strategic plan in cooperation with Federal, State, and local agencies to identify and implement studies to address the most compelling research issues and management questions, and to conduct fundamental environmental monitoring studies.
This project will synthesize portions of six projects that deal in diverse but complimentary aspects of sediments in Florida Bay.
The USGS Tampa Bay Study responds to the need to use an integrated science approach for studying the interrelations between geological, biological, chemical, and hydrological components of estuarine systems, and the impact of natural and anthropogenic change to all components of estuarine systems. The USGS Geological (GD), Biological Resources (BRD), Water Resources (WRD), and National Mapping Disciplines (NMD) are working together with other federal, state, and local partners to develop and implement an integrated, multidisciplinary science strategy for estuarine research. Results from this research will enable scientists and resource managers to better assess the fate of our estuaries in the future. The integrated science strategy developed through this project will be used as a model for USGS integrated science in other Gulf of Mexico Estuaries.
