NODC STATION 

 NUMBER 



Description of Field 



NODC reference identity number. 



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



A reference number assigned by NODC for storage-retrieval purposes. NODC 



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



bibliographic and other pertinent information for each cruise. 



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



Degree, 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) 



GMT to nearest tenth of an hour. 



Year. 



Alphabetic or alpha-numeric designator as assigned by the originator. If the year 



of the cruise forms part of the cruise numbering system, the year digits are found 



in preceding field. 



Originator's station number or designator. 



Corrected or uncorrected sounding depth in meters. 



Depth of deepest sample in hundreds of meters to nearest hundred-meter interval. 



Direction from which the dominant waves are coming, in tens of degrees, according 

 to WMO Code 0885. 



Height of dominant waves according to WMO Code 1555. 

 Period of dominant waves according to WMO Code 3155. 



Sea amount (sea state) according to WMO Code 3700 (preceded by the letter A). 

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

 two-digit entry indicates weather according to WMO Code 4677. 



This field is used either for recording instrument code when electronically obtained 

 data are being reported, or for reporting cloud type and cloud amount when con- 

 ventional Nansen cast data are being reported. 

 A two character code representing instrument package of system. 

 Cloud type according to WMO Code 0500. 

 Cloud amount according to WMO Code 2700. 



Assigned by NODC for data storage and retrieval purposes. The NODC Reference 

 Identity and Station numbers combined, uniquely define each station in the NODC 

 archives.
