In order to enhance habitat for nesting Brown Pelicans, terns, Black Skimmers, and gulls, the USFWS has contracted with USGS to conduct project monitoring on North Breton Island from FY23 to FY31. Monitoring conducted by USGS will facilitate evaluation of habitat characteristics and determine restoration success or need for adaptive management.

Coastal environments are dynamic systems that provide high ecological, economical, recreational, and cultural value. Managing coastal systems requires a comprehensive understanding of the complex interactions between geological and ecological processes, as well as the ability to predict both the near-term and long-term impacts of storms and sea-level rise. The Coastal Resource Evaluation for...

Using an iterative qualitative coding process, WARC researchers are identifying objectives, stressors, and management priorities to support the implementation of adaptive management in restoration programs across the Gulf of Mexico.

The goal of the Estuarine and MaRsh Geology (EMRG) Research Project is to study how and where short- and long-term marsh and estuarine coastal processes interact, how they influence coastal accretion or erosion, and how they pre-condition a marsh’s resiliency to storms, sea-level change, and human alterations along the northern Gulf of Mexico (Grand Bay and Point aux Chenes, Mississippi and St...

USGS is collaborating with Mississippi State University to investigate the effects of fire on Gulf of Mexico marshes. The project will include mapping high marsh and monitoring black rail, yellow rail, and mottled duck responses to prescribed fire application.

Researchers are developing acceleration data logger pop-off packages that can be affixed to sea turtles to collect behavioral patterns of diving, surfacing, and general activity levels.

The National Oceanic and Atmospheric Administration (NOAA) and USGS will jointly lead the development of foundational components for Gulf region-wide monitoring.

The Louisiana Coastal Protection and Restoration Authority’s Coastal Master Plan is a blueprint for responding to environmental changes. As part of the agency’s continued engagement, USGS supports model developments and improvements for the 2023 Coastal Master Plan.

Informing Management of the Nearshore and Continental Shelf

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...

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...

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.
