Coastal and Marine Geology Video and Photograph Portal

This portal contains U.S. Geological Survey (USGS) video and photography of the seafloor off of coastal California and Massachusetts, and aerial imagery of the coastline along segments of the Gulf of Mexico and mid-Atlantic coasts. These data were collected as part of several USGS Coastal and Marine Geology Program Seafloor Mapping projects and Hurricane and Extreme Storm research. The USGS Coasta

Wave and Orbital Velocity Model Data for the California Continental Shelf

The oceanographic processes that disturb the continental shelf include the actions of surface waves, internal waves, and currents (tidal, density, wave-driven, wind-driven, and geostrophic). Because the North Pacific Ocean can generate extremely large surface waves that yield relatively high near-bed wave orbital velocities, wave-generated near-bed currents are often considered to be the dominant
