Informing Management of the Nearshore and Continental Shelf
Gulf Coast Wetland Shoreline Change
Land and seafloor slopes are generally low along the coasts in the Mid-Atlantic and Gulf Coast states, making wetlands and estuaries vulnerable to sea level change, subsidence, and extreme events (e.g., hurricanes and tropical storms). Land-use change and land loss have been mapped extensively and with increasing frequency, but the link between land loss and the processes responsible for landscape...
Use of Lidar in Coastal Studies
Since 1998, airborne light detection and ranging, or lidar, capabilities have been developed and utilized to support CMHRP research projects and hazard assessments. Lidar is a remote-sensing technique that measures distance to a target by sending out light energy and detecting how long it takes the reflected pulses to return to the sensor. Lidar data provide information about the elevation, shape...
Identification of Hydrologic Controls on Coastal Spartina patens Marshes and Optimal Hydrological Conditions for Sustainable Mottled Duck Habitat
Mottled ducks rely on the coastal marshes of the Texas Chenier Plain, which are considered among the most critically endangered habitats in the United States. USGS scientists are evaluating what might be contributing to the degradation of high-quality mottled duck habitat to better understand the causes of habitat loss and subsequently mitigate those losses.
Mississippi Coastal Improvements Program (MsCIP)
In 2009, the Mississippi Coastal Improvements Program (MsCIP) was developed by the U.S. Army Corps of Engineers (USACE), Mobile District in conjunction with other Federal and State agencies, to help reduce future storm damage along the Mississippi Gulf Coast. The Comprehensive Plan for MsCIP includes restoring the Mississippi barrier islands and over 3,000 acres of wetland and coastal forest...
Alabama Barrier Island Restoration Assessment
This project is a collaborative effort between the USGS, U.S. Army Corps of Engineers (USACE), and the State of Alabama funded by National Fish and Wildlife Foundation (NFWF) to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama. The project is focused on restoration options that protect and restore habitat and living...
SPARROW modeling: Estimating nutrient, sediment, and dissolved solids transport
SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources. Interactive, online SPARROW mapping tools allow for easy access to explore relations between human activities, natural processes, and...
Barrier Island Comprehensive Monitoring Program (BICM)
The goal of the State of Louisiana Barrier Island Comprehensive Monitoring (BICM) program is to provide long-term data on the barrier islands of Louisiana that could be used to plan, design, evaluate, and maintain current and future barrier-island restoration projects.
Integrating Mapping and Modeling to Support the Restoration of Bird Nesting Habitat at Breton Island National Wildlife Refuge
Breton Island, located at the southern end of the Chandeleur Islands, Louisiana, is part of the Breton National Wildlife Refuge (NWR) established in 1904 by Theodore Roosevelt. Breton NWR is recognized as a globally important bird habitat because of the resources it provides, and hosts one of Louisiana's largest historical brown pelican nesting colonies. Without actions to restore sand to the...
Coastwide Reference Monitoring System (CRMS)
CRMS uses a multiple reference approach to biological monitoring and uses aspects of hydrogeomorphic functional assessments and probabilistic sampling that address the limited effectiveness of the traditional paired-reference monitoring approach in Louisiana. This approach includes a suite of sites that encompass the range of ecological conditions for each stratum, with projects placed on a...
Urban Waters Federal Partnership - Suspended Sediment and Nutrient Delivery to the Gulf of America
Suspended sediment and nutrients from greater San Antonio can affect instream ecological health of the San Antonio River and ultimately impact Gulf of America bays and estuaries. Real-time monitoring in urban and rural parts of the river basin may provide a glimpse into the importance of urban sediment and nutrient sources. Real-time sensors provide a tool to better understand and manage water...
DISCOVRE - Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems Project
This project uses amplicon sequencing, and functional microarrays to examine the microbiomes of several deep-sea coral species, with priority given to species that are also of interest to the population genetics group: Desmophyllum dianthus, Lophelia pertusa, Enallopsammia sp., and Acanthogorgia sp. The project also uses metagenomics to survey benthic habitats including coral mounds, cold seeps...
