CODING THE DETAIL CAEU) INFORMATION 



General instructions for entries on the data form: 



1. Columns 32, 31, and k-2, marked _i, may be used for the 

 following purposes: 



a) For insertion of an additional decimal place, 

 if needed, or 



b) For insertion of a "precision of measurement" 

 indicator. An alphabetic code, applicable to 

 depth, temperature, and salinity, will indicate 

 the estimated limits of accuracy determined by the 

 observer. This code, presently under development, 

 vill be distributed as Table 29. (Columns 32, 37, 

 and ii2 cannot be used simultaneously for any one 

 cruise or station for both additional decimal places 

 and precision of measurement indicator.) 



2. To indicate doubtful depth, temperature, and salinity place 

 a question mark (?) in the indicator columns (i.e.. Columns 32, 

 37, and 42) or in the case of oxygen and optional chemistry after 

 the last numeral of the value in the last column of the field. 

 The last column of each field has been widened on the data form 

 to allow for the possible entry of both a numeral and a question 

 mark.
