The grid was generated from bathymetric contours (cowbathy.shp, also in this data set) mapped by Chase and others (1992a, b) and by Grim and others (1992) from various sources of bottom topography of the continental margin off the states of Washington, Oregon, and California. Purpose: These data are provided to complete a compilation of legacy data, but any users seeking bathymetric data for analysis or display is referred to more recently compiled data such as ETOPO1 (Amante and Eakins, 2009). > These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information. Supplemental_Information: Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcGIS format, this metadata file may include some ArcGIS-specific terminology. > > >References cited > Amante, C. and Eakins, B.W., 2009, ETOPO1 1 Arc-Minute Global Relief Model: Procedures, Data Sources and Analysis: NOAA National Geophysical Data Center, Boulder CO, NOAA Technical Memorandum NESDIS NGDC-24. doi:10.7289/V5C8276M, accessed 6 Feb 2009. > Chase, T.E., Wilde, P., Normark, W.R., Evenden, G.I., Miller, C.P., Seekins, B.A., Young, J.O., Grim, M.S., and Lief, C.J., 1992a, Map Showing Bottom Topography of the Pacific Continental Margin, Cape Mendocino to Point Conception: U.S. Geological Survey Miscellaneous Investigations Series Map I-2090-C, scale 1:1,000,000, http://pubs.usgs.gov/imap/2090/c/ > Chase, T.E., Wilde, P., Normark, W.R., Evenden, G.I., Miller, C.P., Seekins, B.A., Young, J.O., Grim, M.S., and Lief, C.J., 1992b, Map Showing Bottom Topography of the Pacific Continental Margin, Point Conception to Point Loma: U.S. Geological Survey Miscellaneous Investigations Series Map I-2089-C, scale 1:1,000,000, http://pubs.usgs.gov/imap/2089/c/ > Grim, M.S., Chase, T.E., Evenden, G.I., Holmes, M.L., Normark, W.R., Wilde, P., Fox, C.G., Lief, C.J., and Seekins, B.A., 1992, Map Showing Bottom Topography of the Pacific Continental Margin, Strait of Juan de Fuca to Cape Mendocino: U.S. Geological Survey Miscellaneous Investigations Series Map I-2091-C, scale 1:1,000,000, http://pubs.usgs.gov/imap/2091/c/ > NOAA, 2011, GSHHS - A Global Self-consistent, Hierarchical, High-resolution Shoreline Database, version 2.1.1 (March 2011) http://www.ngdc.noaa.gov/mgg/shorelines/data/gshhs/oldversions/version2.1.1/GSHHS_shp_2.1.1.zip Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1955 Ending_Date: 1978 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -133.4954 East_Bounding_Coordinate: -113.4849 North_Bounding_Coordinate: 48.9621 South_Bounding_Coordinate: 29.7446 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: bottom topography Theme_Keyword: bathymetry Theme_Keyword: bathymetric contour Theme_Keyword: Exclusive Economic Zone Theme_Keyword: isobath Theme_Keyword: continental margin Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: environment Theme_Keyword: geoscientificInformation Theme_Keyword: oceans Theme: Theme_Keyword_Thesaurus: Global Change Master Directory (GCMD) Science Keywords Theme_Keyword: Oceans > Bathymetry/Seafloor Topography > Bathymetry Place: Place_Keyword_Thesaurus: Geographic Names Information System Place_Keyword: Washington Place_Keyword: Oregon Place_Keyword: California Place_Keyword: USA Place_Keyword: Point Conception Place_Keyword: Point Loma Place_Keyword: Cape Mendocino Place_Keyword: Strait of Juan de Fuca Place_Keyword: Pacific Ocean Place: Place_Keyword_Thesaurus: none Place_Keyword: north Pacific Ocean Place_Keyword: northeastern Pacific Access_Constraints: None.

Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: A surface interpolated from the contours in this data set was compared to ETOPO1 bathymetric data (Amante and Eakins, 2009). A depth difference calculation determined that COWBATG underestimates heights and elevations with a standard deviation of 130, partly attibutable to horizontally displaced features. > > MIN MAX MEAN STDV > -1983.217 2848.723 -4.279 129.323 (meters) Lineage: Process_Step: Process_Description: Contour data (100-m interval from 200 to 5300 m) from the accompanying shapefile COWBATHY.SHP included in this report and a coastline (for zero depth) from NOAA (NOAA, 2011; Wessel and Smith, 1996) were used to generate a continuous raster with the ArcGIS tool TopoToRaster with the following parameters.
