Locations of samples collected from 1995 through 1999 are recorded in M195MBSP, P295MBSP, N197MBSP, P197MBSP, O499MBSP, and S199MBSP.
These files are part of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program "Monterey Bay National Marine Sanctuary Project" <http://walrus.wr.usgs.gov/mbms>. The data were collected and analyzed between 1994 and 2000.

This is a Point data set. It contains the following vector data types (SDTS terminology):
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 14.232525
Ordinates (y-coordinates) are specified to the nearest 14.232525
Planar coordinates are specified in Meters
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is GRS1980.
The semi-major axis of the ellipsoid used is 6378137.0.
The flattening of the ellipsoid used is 1/298.257.

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 about the shallower areas of the Monterey Bay National Marine Sanctuary.
Except for a few points, point files include only those points for which a 'RECOVERY' was recorded. 'NO RECOVERY' points were added if sample analyses referred to that point. This occurred when small amounts of sample were scraped off the sampling device which had otherwise failed to retain a sample.
Point features present.
