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 file is hand-digetized bathymetry in meters.  The
    letters and plus signs associated with the depths for Fingershoals are
    meaningful to the Karluk scientists.
    The following information was taken from a file called k183ar.bat.
    
    k183fs = 1983 Fingershoals Survey. This year the survey was run on two days,
    July 25, and 27. Good coverage was made as the passes were about 100 meters
    apart. The record was corrected for tidal affects throughout during the
    digitizing process. In the file below, short comments were added in the
    depth column indicating the occurrance of either ridge crest or trough (+ =
    symmetrical ridge crest, B = crest offset to left of center, A = crest
    offset to the right of center).
