Abstract:
This part of DS 781 presents data for the bathymetry and shaded-relief maps of the Offshore of Bodega Head map area, California. Raster data file is included in "Bathymetry_OffshoreBodegaHead.zip," which is accessible from
http://pubs.usgs.gov/ds/781/OffshoreBodegaHead/data_catalog_OffshoreBodegaHead.html.
The bathymetry and shaded-relief maps of the Offshore of Bodega Head Map Area, California, were generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), and by Fugro Pelagos. Mapping was completed between 2007 and 2010, using a combination of 200-kHz and 400-kHz Reson 7125, and 244-kHz Reson 8101 multibeam echosounders, as well as 468-kHz SEA SWATHPlus interferometric system. These mapping missions combined to collect bathymetry (sheets 1, 2) from about the 10-m isobath to beyond the 3-nautical-mile limit of California State Waters.
NOTE: the horizontal datum of the bathymetry data (NAD83) differs from the horizontal datum of other layers in this data series (WGS84). Some bathymetry grids within this map were projected horizontally from WGS84 to NAD83 using ESRI tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88). These data are not intended for navigational purposes.
Purpose:
To expand geologic mapping to the seafloor within the California's State
Waters, to update coastal geologic mapping, and to contribute to a
uniform regional geologic database, which can be used geographic information systems.
Additionally, to provide a geologic map for the public and geoscience community to aid in assessments and mitigation of geologic hazards in the Bodega Bay coastal region and to provide sufficient geologic information for land-use and
land-management decisions both onshore and offshore.
This information is not intended for navigational purposes.
