United States Geological Survey, Menlo Park, California.
Chief Scientist: Roberto Anima. Data (sidescansonar,
bathymetry) of field activity J-4-92-MB in Santa Cruz,
Monterey Bay from 04/20/1992 to 04/23/1992,

Similar information is available for thousands
of other USGS/CMG-related Activities.
If known, available are Activity-specific
navigation, gravity, magnetics, bathymetry,
seismic, and sampling data; track maps; and
equipment information; as well as summary
overviews, crew lists, and information
about analog materials.
If available, access to physical samples is
described in the "WR CMG Sample Distribution
Policy" at:
<http://walrus.wr.usgs.gov/infobank/programs/html/main/sample-dist-policy.html>

This is a Point data set.
It contains the following vector data types (SDTS terminology):
- What coordinate system is used to represent geographic features?
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude.
Latitudes are given to the nearest 0.00001.
Longitudes are given to the nearest 0.00001.
Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.
The flattening of the ellipsoid used is 1/298.257.

Integrated navigation (SINS) data
Anima picked times of line SOLs, inflection points, and EOLs.
When GOOD.NAV or HAND.NAV exists, fixes for those times were interpolated.
When no digital nav exists, Anima figured fixes and Degnan keypunched.
