Assess California offshore depths. This dataset is not suitable for navigation.
Bathymetric contour lines for California that generally cover the Exclusive Economic Zone (EEZ), an area extending 200 nautical miles from all United States possessions and trust territories. Isobath resolution 100 meters, beginning at the 200 meter contour. This dataset was updated in September 2005 to include all of the EEZ for the California vicinity. This dataset was extracted from a larger bathymetric dataset called "caorwa" that covers the EEZ for Calfornia, Oregon, and Washington.
