The USGS Southeast Regional Office has funded a cross-center collaboration between the Wetland and Aquatic Research Center and the Texas Water Science Center for the development of the Gulf of Mexico Water Dashboard. The objective of this effort is to expand the Texas Water Dashboard platform to include the coastal regions of the five Gulf states...
Mangroves have decreased worldwide due to human development, climate change and other forces. In southwest Florida, tremendous growth and development pressure has resulted in appreciable losses in mangrove wetlands.
USGS scientists have been involved for a number of years in the development and use of Structural Equation Modeling (SEM). This methodology represents an approach to statistical modeling that focuses on the study of complex cause-effect hypotheses about the mechanisms operating in systems.

SEM is increasingly used in ecological and environmental...
Manatees are tropical to subtropical in distribution and, with few exceptions, Florida is the northern limit of their natural winter range. The availability of warm-water habitat during winter is critical for the future persistence of the population in Florida.
The Gulf sturgeon, Acipenser oxyrinchus desotoi, has been listed as Threatened since 1991. Beginning in 1986, USGS has been investigating sturgeon population abundance and ecology throughout its range, but mostly in the Suwannee River.
Turbid water conditions make the delineation and characterization of benthic habitats difficult by traditional in situ and remote sensing methods. Consequently, only a small fraction of this valuable resource has been mapped or characterized.
Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide a plethora of resources including plant and wildlife habitat, commercial and recreational economic activity, water quality, and natural barriers against storms.
Freshwater wetlands provide critical habitat for a diverse array of organisms, including many amphibians. Yet, under the threat of climate change, these habitats are among the most imperiled ecosystems on Earth.
Using historic maps and contemporary imagery, we will quantify and synthesize existing data on the distribution and abundance of shorebirds in North Carolina and changes in habitats related to storms, such as Hurricane Sandy; coastal development, such as the Intracoastal Waterway; inlet modifications; and shoreline erosion to give us a better...
While the historic focus of vegetation condition is the bulk live and dead compositions, these variables provide no information on the structure of vegetation (density and orientation). Canopy structure information is critical for monitoring status and trends, and essential in climate, weather, and ecological studies.
The interior marshes of the Ten Thousand Islands National Wildlife Refuge (TTINWR) are currently negatively impacted by sea level rise through saltwater intrusion from the south which furthers mangrove encroachment into the freshwater marsh.
Storm surge waves and tides of hurricanes have the propensity to wash up marsh detritus of dead reeds and leaf debris along with plastic trash and lumber, commonly referred to as wrack, from overwashed beaches, marshes, forests, streets, and lawns.
Support tasks performed by the WARC Advanced Applications Team for Hurricane Sandy-related projects include aerial imagery capture and processing, standards-compliant data formatting and transformation, metadata creation, and visualization of data in a spatial context.
