FILE TYPE 005 - AANDERAA CURRENT METER - 04/13/83 VERSION  

    THIS FORMAT IS DESIGNED TO SUPPORT CIRCULATION STUDIES OF THE OCEANS 
USING AN AANDERAA TYPE CURRENT METER.  THESE CURRENT METERS USE THE 
EULERIAN METHOD TO MEASURE SIMULTANEOUSLY THE DIRECTION AND SPEED OF THE 
WATER MOVEMENT AT A FIXED POINT.

    THE FORMAT CONTAINS FOUR DATA RECORD TYPES TO:  1) IDENTIFY THE BUOY  
STATION AND PROVIDE SPACE FOR COMMENTS, 2) TO IDENTIFY THE POSITION AND 
DEPTH OF THE INSTRUMENT, AND 3) TO PROVIDE CURRENT SPEED, DIRECTION AND 
ENVIRONMENTAL DATA. 

    EACH RECORD IS 60 CHARACTERS LONG AND IS SORTED BY STATION NUMBER, 
SEQUENCE NUMBER, AND RECORD TYPE.  

     THE FIRST NINE COLUMNS FOR ALL RECORDS ARE TO BE USED FOR FILE TYPE
(COLUMNS 1-3) AND FILE IDENTIFIER (COLUMNS 4-9). THE FILE IDENTIFIER, TO
BE ASSIGNED BY THE ORIGNATOR, IS A UNIQUE ORIGINATOR ID FOR EACH DATA  
SUBMISSION. AFTER SUBMISSION, THE NODC REASSIGNS TO THIS FIELD A UNIQUE 
NODC IDENTIFIER FOR INTERNAL USE.
