		designator for the data contained on this disk.
		(i.e. at7-15  => Cruise 15 of the 7th Atlantis voyage)

/docs		A directory containing documentation pertaining to the
		file formats in use on this disk.

		Athena.

Copies of Diskinfo.txt, CRUISE_ID, /docs and /scripts are contained on all
cruise disks.  The remaining subdirectories are placed on the cruise disks 
as space permits (i.e. the XBT data subdirectory is likely to be located on 
the last disk of the cruise set).  

If a particular directory is missing, it indicates that no data of that 
type was collected during the cruise.  

Additional directories may be added for storing data from special
instrumentation.
