Title:
Geophysical data of field activity L-3-80-NP in North Pacific from 05/22/1980 to 06/04/1980
Abstract:
Chief Scientist: Andy Stevenson. Geophysical data (airgun, uniboom, 3dot5khz, 12khz, gravity, chaindredge) of field activity L-3-80-NP in North Pacific from 05/22/1980 to 06/04/1980, <http://walrus.wr.usgs.gov/infobank/l/l380np/html/l-3-80-np.meta.html>.
Supplemental_Information:

Equipment Used -
airgun single-channel airgun
uniboom
3dot5khz 3.5 khz bathymetry
12khz 12 khz bathymetry
gravity
chaindredge
Notes -
Magnetics files were removed from this activity on 2012Oct29
because values were bad and no evidence of magnetic data collection
was present in analog records of this field activity.

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>
Primary access to the USGS/CMG Information Bank's digital data, analog data, and metadata is provided through... <http://walrus.wr.usgs.gov/infobank/>
This page accomodates a variety of search approaches (e.g., by platform, by region, by scientist, by equipment type, etc.).

      Indirect_Spatial_Reference: North Pacific
      This is a Point data set. It contains the following vector data types (SDTS terminology):
      • Point

    2. 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.
