Geology and Sediment Availability - Coastal System Change at Fire Island, New York
Sediment supply is a critical control on barrier island vulnerability and resilience over a variety of time scales (e.g., storms to sea level rise). Past work at Fire Island and elsewhere has demonstrated a link between inner shelf sediment availability and barrier island evolution over geologic and historical time scales. However, there have been few opportunities to explore nearshore sediment...
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).
Barrier Island Evolution - Applied Research
Assessments include depiction of trends (the past points to the future), updated observations (topography/bathymetry), and predicted sensitivity of barrier island evolution to possible climatologies and restoration plans.
Barrier Island Evolution - Geologic Analysis
Quantifying changes in morphology and sediment distribution over short time scales will demonstrate how geologic variability influences medium-term barrier island response and near-term barrier island trajectories and help to refine sedimentological boundary conditions for morphologic evolution models.
Barrier Island Evolution - Numerical Modeling and Oceanography
Numerical models compliment the collection of geophysical data by hindcasting and forecasting sediment transport pathways, natural island trajectories, and berm/island interactions over larger and higher resolution domains and time periods.
Using Video Imagery to Study Coastal Change: Sand Key, Florida
Video observations of Sand Key, Florida, are used to monitor a range of coastal processes, for example changes in the shoreline position, both seasonally and due to long-term effects such as sea-level rise, and instances of beach and dune erosion during extreme storm events.
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.
Hurricane Irma - Forecast and Documentation of Coastal Change
Hurricane Irma coastal change forecast and pre- and post-storm photos documenting coastal change.
Hurricane Nate - Forecast and Documentation of Coastal Change
Hurricane Nate coastal change forecast and pre- and post-storm photos documenting coastal change.
Operational Total Water Level and Coastal Change Forecasts
The viewer shows predictions of the timing and magnitude of water levels at the shoreline and potential impacts to coastal dunes.
