Photograph of the seafloor off the California coast shows coarse sand, shells and a sunflower sea star. This photograph supports the California Seafloor Mapping Program, a cooperative program established in 2007 initiated by state and federal agencies, academia and private industry. Data collected during this project reveal the seafloor offshore of the California coast in unprecedented detail and provide an ecosystem context for the effective management of this precious marine resource.

The USGS has completed the second phase of releasing thousands of photos and videos of the seafloor and coastline through their Coastal and Marine Video and Photography Portal.
Most of these marine and coastal scenes have never been seen before or mapped at this level of detail. A more accurate perspective of these areas helps coastal managers make important decisions that range from protecting habitats to understanding hazards and managing land use.
This USGS portal is unique, due to the sheer quantity and quality of data presented. It is the largest database of its kind, providing detailed and fine-scale representations of the coast and seafloor. The “geospatial context” is also unique, with maps that display imagery in the geographic location where the images were recorded.

Seafloor character map of the San Francisco Region. This is a type of habitat map that classifies the seafloor based on surface hardness and roughness. Such maps are used in various types of ecosystem assessments and seafloor zoning, such as delineation or monitoring of marine protected areas.
