Codes Utilized 



A complete description of the codes utilized in the tabulation of oceanographic station data can be 

 found in National Oceanographic Data Center publication M-2, Processing Physical and Chemical 

 Data from Oceanographic Stations. (Rev. August 1964, supplement issued May 1966.) 



To facilitate use of the oceanographic station data listing, entry headings which are not self- 

 explanatory are described below. 



REFID NODC reference indentity number. 



CONSEC Consecutive station number. 



BOTDP iB) 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 WMO 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. Transparency 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 bv 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. 



ORIG (B) Originator's reference number in two parts — cruise number or 3 characters (if year of cruise forms part of cruise 



number years digits may sometimes only be found in "Year" field), and station number. 



TEN SQ Ten-degree square — modified Canadian square number. 



5 SQUARE Five-degree squares — modified Canadian system. 



2 SQUARE Two-degree squares — modified Canadian system. 



1 SQUARE One-degree squares — modified Canadian system. 



CASTNUM (B) Number of cast on multicast stations (blank when messenger time is given). 



TIME (B) Time of release of messenger in hour and tenths for applicable observed levels. If multicast series extends past 



midnight. 24 hours are added to cast time of next dav. Beginning time for STD is given at first obs depth. 



LVLTYP Type of record at depth indicated. "OBS" — observed values. For STD recorder = level of data read-out. 



"STD" — NODC standard interpolated values. "ORG" — Standard or other depths earning non-NODC inter- 

 polated values. "LIT" — Interpolated standard depth values used as obs for computational purposes. Note — 

 When an observed level coincides with a STD depth level, both "STD" and "OBS" lines will appear. 



DEPTH Depth of sample (or standard level) in whole meters. Prefix 'T" indicates thermometrically determined depth (depth 



of unprotected thermometers). Subscript "Q" indicates that the value is marked doubtful by the originator. A 

 value designated as implausible by NODC is marked with a "P". Postscript "Z" indicates uncorrected and 

 inaccurate 'Wire-out' depths (high wire angle present). 



TEMP (B) Temperature in degrees celsius. For 'Q' and 'P' notation see depth field. 



SAL (B) Salinity in parts per thousand. For "Q* and 'P' notation see depth field. 



SIGMA-T (B) Seawater density anomaly to 2 decimal places. When depth, temp, or salinity is doubtful. a'Q" is suffixed. An asterisk 



indicates a decrease of 0.02 or more from the previous level. 



DYNDPTH Dynamic depth anomaly in dynamic meters to millimeters. 



SND VEL (B) Sound velocity in meters per second to decimeters according to Wilson's formula. (A standard depth-pressure term is 



used for stations not beginning at the surface). 



OXYG (B) Oxygen in ML/L to hundredths.
