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:

Bathymetry Data
09/26/2002 clint f-1-01-nc.305_060
Removed all records that automerge interpolated nav
beyond a span of 0.5 second.
0.5 second limit determined by sorting based on time
span, then examining results for "break" in data values.
Used NAVED to compare "retained" vs "removed" records
and determined division was appropriate. -- Clint
