Columns 19-20 YEAR 



Enter last two digits of year as determined by Greenwich Mean Time (GMT). 



Columns gl-g2 MONTH 



Enter month as determined by GMT, using numerals 01 through 12. 



Columns 23-24 DAY 



Enter day of month as determined by GMT, using numerals 01-31. If one 

 or more oceanographic casts were made on the day prior to the day reported 

 in this field, subtract one day from the station date and enter this date 

 in Columns 23-24. Additionally, 2k hours must be added to the actual station 

 time. 



Columns 2^-27 TIME 



Enter hour and tenths of hour of time of station in GMT. Time normally 

 should represent the time when the surface environmental information was 

 taken, except as mentioned above. Table k converts zone time to GMT and 

 Table 2 converts minutes to tenths of an hour. Caution should be exercised 

 when using Table h, however, as non-standard time zone boundaries are not 

 apparent from this table. 



Columns 28-30 ORIGINATOR'S CRUISE NUMBER 



Enter the number, alphabetic or alpha-numeric designator or its closest 

 equivalent, assigned to the cruise by the originator. If year is part of 

 cruise number, do not enter year in this field; year precedes cruise number 

 when listed. (See Appendix III. ) 



EXAMPLE: MRL 59O6 = OO6 



Columns 31-33 ORIGINATOR'S STATION NUMBER 



Enter ship's station number as assigned by the originator. When com- 

 plex station numbering systems are employed (such as station numbers contain- 

 ing positional codes) which require more than three columns to record, 

 continue the remaining numerals or letters in Columns 68-72 of the Special 

 Observations field. However, in these cases. Column 72 may contain a 

 numeral only.
