Hazards

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 waves...

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.

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.

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.

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.

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.

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.

Synchronized field work focused on geochemistry, geology, and metabolic processes overlaid on a habitat map of an entire reef to produce a synoptic overview of reef processes that contribute to carbonate precipitation and dissolution.

This project documents paleoceanographic, climatic, and environmental changes in the Gulf of America 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.
