NODC CODES USED IN THE OCEAN CLIMATE LABORATORY DATA SYSTEM.
 CODES ARE THE SAME AS THOSE USED BY NODC EXCEPT WHERE A VALUE IS
 FOLLOWED BY A VALUE IN PARENTHESES.  THE VALUE IN PARENTHESES IS
 THE VALUE NODC USES.  NA MEANS NOT AVAILABLE (AS AN OPTION).
 [*] MEANS DEFAULT VALUE.  THE DEFAULT VALUE IS ASSUMED IF THE
 CODE IS NOT INCLUDED IN AN OCL PROFILE.
