Notes -
The R/V Tommy Munro is owned and operated by the Univ. of Southern
Mississippi Institute of Marine Sciences. The ship operates out of Biloxi,
Mississippi. The cruise was a cooperative venture between the USGS and the
Univ. of Mississippi (McGee), USGS-MMRI cruise.

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:
