Coastal Processes

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. In order to better constrain controls on coastal vulnerability and evolution, the region’s sediment sources, transport pathways and sediment sinks must be identified. This project defines the geologic framework of the Delmarva coastal system through...

The Sea Floor Mapping Group (SFMG) is a core capability at the Woods Hole Coastal & Marine Science Center (WHCMSC) that provides support for coastal, lacustrine and marine geologic research. The staff has a wide-range of expertise and is responsible for geophysical and sampling data acquisition, processing, interpretation and publication, logistics, design, and research and development. SFMG has...

The Aerial Imaging and Mapping group (AIM), at the U.S. Geological Survey Woods (USGS) Hole Coastal and Marine Science Center provides UAS services to scientists to advance the science mission of the Coastal and Marine Geology Program. Scientists at the Woods Hole Coastal and Marine Science Center have been using UASs to acquire imagery of coastal and wetland environments, which is then used to...

Exchange of flows, sediment, and biological particles between the inner shelf and back-barrier estuaries are significant for determination of extreme water levels, maintenance and formation of inlets, barrier-island evolution, and pollutant and larval transport. These connections are controlled by cross-shore processes including wave-driven inner-shelf and near-shore processes, dune overtopping...

Policy-makers, individuals from government agencies, and natural resource managers are under increasing pressure to manage changing coastal areas to meet social, economic, and natural resource demands, particularly under a regime of sea-level rise. Scientific knowledge of coastal processes and habitat-use can support decision-makers as they balance these often-conflicting human and ecological...

Puerto Rico and the Virgin Islands are located at an active plate boundary between the North American plate and the northeast corner of the Caribbean plate. Plate movements have caused large magnitude earthquakes and devastating tsunamis. The USGS has an ongoing program to identify and map the faults in this region using various geophysical and geological methods in order to estimate the location...

The primary objective of this project is to increase our understanding of the physical processes that cause coastal change, and ultimately improve our capability to predict the processes and their impacts. This will be approached by using geophysical surveys, oceanographic studies, and predictive models to investigate the interactions of shoreline, nearshore, and offshore sediment transport...

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is mapping sea-floor geology and sedimentary environments offshore of Rhode Island. This site provides links to bathymetric, sidescan-sonar, sediment, photographic, seismic-reflection, and interpretive datasets, all presented in Geographic Information System (GIS) formats and...

This project is complete and the website is archived and no longer updated. The U.S. Geological Survey and others are promoting the development of an open-source numerical model for sediment-transport in coastal regions. We are collaborating with other federal agencies, academic institutions, and private industry, with the goal of adopting and/or developing one or more models for use as scientific...

This project is complete and the website is archived and no longer updated. The USGS, the State of North Carolina and university researchers, mapped the regional sedimentary framework of the inner shelf of northern North Carolina to understand coastal processes, including erosion and the impacts of shoreline change. The study area includes communities along the Outer Banks, several national and...
