This is a Vector data set. It contains the following vector data types (SDTS terminology):
Planar coordinates are encoded using row and column
Abscissae (x-coordinates) are specified to the nearest 50.000000
Ordinates (y-coordinates) are specified to the nearest 50.000000
Planar coordinates are specified in meters
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.
sequential feature numbers
depth to transgressive surface
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.

Data points are approximately 1 m apart along tracklines and 1,000-2,000 m apart between tracks. 50-m cell size for interpolation is better supported along track than between.
The chirp sonar instrument is deployed under the research vessel with about 10 m of variation in position. The sparker position may vary as much as 20 m from the navigation reference on the vessel.
Sediment thickness data points exported from Seisworks profiling software were processed within the California 3-nmi limit, omitting values over Hueneme Canyon.
All vector geometry and attributes are present.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None.
- Not to be used at scales greater than 1:24,000. Not to be used for navigation.
