Mapping was completed between 1998 and 2014 using a combination of 30-kHz Simrad EM-300 and 200-kHz/400-kHz Reson 7125 multibeam echosounders, as well as 234-kHz and 468-kHz SEA SWATHplus bathymetric sidescan-sonar systems. The mapping missions collected bathymetry data from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters.\nBathymetric contours were generated separately from the modified 2-m and 5-m bathymetric surface then merged to one final contour dataset. 10-m intervals were generated in water depths shallower than 100 m, at 50-m intervals from 100 to 200 m, and at 200-m intervals in water depths deeper than 200 m. The original surface was smoothed using the Focal Mean tool in ArcGIS and a circular neighborhood with a radius of 20 to 30 m (depending on the area). The contours were generated from this smoothed surface using the ArcGIS Spatial Analyst Contour tool. The most continuous contour segments were preserved; smaller segments and isolated island polygons were excluded from the final output.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.556f90c3e4b0d9246a9fd0b8.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://cmgds.marine.usgs.gov/data/csmp/MontereyCanyon/data_catalog_MontereyCanyon.html", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_556f90c3e4b0d9246a9fd0b8", "keyword": ["sea-floor characteristics", "contouring", "computational methods", "imageryBaseMapsEarthCover", "Seafloor Topography", "geospatial datasets", "geospatial analysis", "Moss Landing", "Bathymetry", "maps and atlases", "Coastal and Marine Geology Program", "USGS:556f90c3e4b0d9246a9fd0b8", "Pacific Ocean", "Pacific Coastal and Marine Science Center", "geoscientificInformation", "U.S. Geological Survey", "bathymetry", "Monterey County", "USGS", "CMGP", "PCMSC", "State of California"], "modified": "2022-02-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.06, 36.68, -121.79, 36.84", "theme": ["geospatial"], "title": "Contours--Monterey Canyon and Vicinity, California"}
