Coastal/Marine Hazards and Resources
Four video cameras overlook the coast at Isla Verde in San Juan, Puerto Rico. Two of them focus on the shoreline: Camera 1 looks at the nearby beach and eastward along the shore, and Camera 2 looks farther away to the eastern end of the beach. The other two look out across the reefs: Camera 3 to the north-northwest, and Camera 4 to the northeast.
Coastal Environmental Geochemistry research at the Woods Hole Coastal and Marine Science Center spans multiple ecosystems and topics, including coastal wetlands, aquifers, and estuaries, with the goal of providing data and guidance to federal, state, local, and private land owners and managers on these vital ecosystems.
We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.
MarFac is the operational arm of the Pacific Coastal and Marine Science Center. The Marine Facility staff provides mechanical and electronics support for marine field operations.
Here we describe the data collection methods and techniques of the California Seaflor Mapping Program: mapping, video and photography ground-truthing, and seismic profiling data collection.
USGS and the California Ocean Protection Council (COPC) are supporting development of peer-reviewed map sets for California’s mainland State Waters.

The map sheets display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow (to about 100 m) subsurface geology. The total number of sheets varies by area but always includes a core of the same 10 sheets and may include specialty sheets depending on the region. The available sheet sets are listed by study...
California Seafloor Mapping Program data and map publications have and will be used for a large range of applications in coastal zone management and research.
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).
Prediction of the severity of ground failure in Quaternary deposits is a critical component of hazard studies. Model development in our project is focused on design and application of methods for quantitative assessment of ground deformation potential.
