This is a Raster data set. It contains the following raster data types:
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.

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.
Not applicable for raster data.
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.
