USGS and the California Ocean Protection Council (COPC) are supporting development of peer-reviewed map sets for California’s mainland State Waters.
USGS and the California Ocean Protection Council (COPC) are supporting development of peer-reviewed map sets for California’s mainland State Waters. Each map set contains 10 downloadable pdf map sheets (most at 1:24,000) for a selected coastal “block.” Map sheets show bathymetry, backscatter, perspective views, seafloor “character” (video-supervised automated classification of bathymetry and backscatter), groundtruthing imagery, potential habitats, seismic-reflection profiles, sediment distribution and thickness, and onshore-offshore geology. Some map sets include additional thematic sheets that highlight detailed geomorphology, predicted distribution of benthic macro-invertebrates, and natural offshore hydrocarbon seepage. These map publications also include an explanatory pamphlet and a set of digital data layers (about 20 to 25 per mapping block) that are compiled in a USGS CSMP Data Catalog (Golden, 2014).
Consult the Progress page for the latest news on publications. As of April 2018, 25 complete map sets have been published. Each map set represents a large collaborative effort (42 co-authors have been involved) representing federal, state, academic, and private-sector partners. The examples shown below are from the “Hueneme Canyon and Vicinity” map set.
