Description of Field 



NODC reference identity number. 



Indicates nationality of the institute or agency conducting the survey or expedition.

 lication C-1, Reference Sources of Oceanographic Station Data, gives complete bibli- 

 ographic and other pertinent information for each cruise. 



Alphabetic representation of ship's name (or ICES numeric ship code). 



Degrees, minutes, and tenths of minutes, N or S. 



Degrees, minutes, and tenths of minutes, E or W. 



The letter D appears in this column if extensive drift occurred while on station. 



Marsden square number according to the Marsden square system. 



The one-degree square number according to the Marsden square system. 



Date and time given by the originator (GMT). 



Month (GMT). 



Day (GMT).

If preceded by the letter X, weather according to WMO Code 4501. A numeric two- 

 digit entry indicates weather according to WMO Code 4677.
