INSTRUCTIONS FOR PUNCHING NODC OCEANOGRAPHIC STATION CARDS 

 FROM THE PHYSICAL AND CHEMICAL DATA CODING FORM 



(See Appendix I, page 105, for sample Oceanograpkic Station Card.) 



In general the physical and chemical data form for oceanographic 

 station data is arranged in such a manner that most of the numeric and 

 alphabetic entries can be punched directly Into the corresponding 

 colimns of the punch card. The alphabetic punch code used at NODC is 

 the standard IBM code. The correct entry columns for certain over- 

 punches, however, cannot readily be determined from the data form. 

 The correct entry for these overpunches is given in the punching 

 instructions below.
