Coastal Change Hazards

Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative...

Estuarine and MaRsh Geology Research Project

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...

Coastal Sediment Availability and Flux (CSAF) Project

Sediments are the foundation of coastal systems, including barrier islands. Their behavior is driven by not only sediment availability, but also sediment exchanges between barrier island environments. We collect geophysical, remote sensing, and sediment data to estimate these parameters, which are integrated with models to improve prediction of coastal response to extreme storms and sea-level...

Coastal System Change at Fire Island, New York

Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm...

Sea-level and Storm Impacts on Estuarine Environments and Shorelines (SSIEES)

This project assesses the physical controls of sediment and material exchange between wetlands and estuarine environments along the northern Gulf of Mexico (Grand Bay Alabama/Mississippi and Vermilion Bay, Louisiana) and the Atlantic coast (Chincoteague Bay, Virginia/Maryland).

Hurricane Sandy Response - Storm Impacts and Vulnerability of Coastal Beaches

Scientists evaluated and improved the accuracy of pre-landfall forecasts of storm-induced coastal erosion hazards for Northeast beaches using data from post-Sandy lidar sruveys, beach morphology, and storm hydrodamics.

Hurricane Sandy Response - Barrier Island and Estuarine Wetland Physical Change Assessment

This project integrated a wetland assessment with existing coastal-change hazard assessments for the adjacent dunes and beaches of Assateague Island, Maryland, to create a more comprehensive coastal vulnerability assessment.

Climate and Environmental Change in the Gulf of Mexico and Caribbean

This project documents paleoceanographic, climatic, and environmental changes in the Gulf of Mexico and adjacent land areas over the last 10,000 years. The paleoenvironmental data is used to determine rates of change in the past, and to better understand both the natural and anthropogenic factors that contribute to climate variability on inter-annual to millennial timescales.

Geologic and Morphologic Evolution of Coastal Margins

A combination of geophysics, sediment sampling, and chronology techniques are used to characterize the regional geomorphologic response of coastal systems to environmental changes.

Alabama Barrier Island Restoration Study

Scientists are collecting geologic data and developing a numerical model framework to understand the evolution of Dauphin Island over the last 15-20 years and assess the future evolution of the island over the next 15-50 years, including the impacts of potential restoration scenarios.

Barrier Island Evolution

The Barrier Island Evolution Project addresses a research gap between the short time scale of individual storms (hours to days) and the longer time scales associated with the historic and geologic evolution of the coastal system (decades to millennia).
