Codes Utilized 



A complete description of the codes utilized in the tabulation of oceano- 

 graphic station data can be found in National Oceanoo^raphic Data Center 

 publication M-2, Processing Physical and Chemical Data from Oceano- 

 graphic Stations. (Rev. August 1964, supplement issued May 1966.) 



To facilitate use of the oceanographic station data listing, entry head- 

 ings which are not self-explanatory are described below. 



REFID NODC reference identity number. 



CONSEC Consecutive station number. 



BOTDP (B) Uncorrected sounding depth in meters. 



SHIP (B) - NODC assigned platform identity code. 



DATA USE Entry 1 identifies DNP data. 



AREA -■ NODC ocean area code. 



CLOUD T/A (B) Cloud type according to WMO code 0500 and cloud 



amount according to WMO code 2700. 



Wave observations 



DIR Direction from which dominant waves are coming 



in tens of degrees according to WMO code 0885. 



HGT Height of dominant waves according to WIVIO code 



1555. 



PER Period of dominant waves according to WMO code 



3155. 



SEA (B) Sea state according to WMO code 3700. 



CL/TR (B) Water color according to Forel-Ule code. Trans- 

 parency in meters as determined by Secchi disc. 



WIND DIR (B) Direction from which wind is blowing in tens of 



degrees according to WMO code 0877. 



WIND SPD (B) Wind speed in knots. 



WIND FOR (B) Wind force in beaufort code. 



WEATHER (B) Weather code — If preceded by letter X is according 



to WMO code 4501. A numeric two digit entry 

 indicates weather according to WMO code 4677. 



INST Instrument used for observation — "Nansen Cast" 



indicates station consists of Nansen cast data — 

 "STD Recorder" indicates station consists of 

 STD data or a mixture of STD and Nansen cast 

 data. 



TRACE DIR (B) "Trace" indicator U (UP), D (DOWN), and A 



(AVERAGED)— used with STD casts, and 

 specify that data were taken while hoisting or 

 lowering respectively or that the two traces were 

 averaged. 



DURATION (B) Time elapsed during raising or lowering of the 



STD recorder to tenths of hours.
