Diskinfo.txt	This file.

CRUISE_ID	A text file containing the ship, voyage and cruise
		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.

/scripts	Utilities useful for manipulating the various data files.

/dive#/athena	General data files constructed by Alvin's Athena data logger.

/dive#/CTD      Alvin CTD data.

/dive#/CTFM     Alvin CTFM sonar data.

/dive#/DataCollectors        Data files generated by special purpose data
		collectors.  Frequently these files result from the use of a 
		unique science tool or instrument (i.e. heat flow probe), 
		which is not deployed continuously.  The name of the file 
		indicates the type of data that it contains.


/dive#/DVLNav   Alvin in-hull navigation files.

/dive#/ACNAV    Alvin surface navigation files.

/dive#/HeatFlow Heat flow measurement data.

/dive#/IDAQ/cruise#     Alvin Framegrabber images and data are here in 'web browsable' form.

/dive#/Imagenex Imagenex sonar data.

/dive#/Magnetometer    Alvin magnetometer data.



/dive#/Science  Data files located in the "Science" directory of the
		Alsci0 computer.  These normally contain data collected by 
		applications provided by the science party.

/Pictures Directory containing image files from hand held cameras.

An Alvin dive data disk will contain as many dives as will fit completely.
In the event that a disk will not hold all the data associated with a single 
dive, continuation disks will be used. 

Copies of Diskinfo.txt, CRUISE_ID, /docs and /scripts are contained on all
dive disks, including "continuation" disks if needed for a single dive.

If a particular directory is missing, it indicates that no data of that type 
was collected during the dive.  
 
Additional directories may be added for storing data from special
instrumentation.
