- Abstract:
-
Chief Scientist: Sam Clarke. Data (seismic) of field
activity J-1-93-NC in Off Crescent City, Mendocino, and
Humboldt Bay, Northern California from 09/16/1993 to
09/30/1993,
<http://walrus.wr.usgs.gov/infobank/j/j193nc/html/j-1-93-nc.meta.html>.
- Supplemental_Information:
-
Equipment Used -
seismic EPC high resolution seismic system, Elics digital system
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.
