Codes Utilized 



A complete description of the codes utilized in the tahulation 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 referente indenlilv number. 



CONSEC Ctinsfculive statmn nuniher. 



BOTDP (B) L'ncurTfcted sounding dt-pth in meters. 



SHIP (B) NODC assigned platform idenlilv code. 



DATA USE Enlr> 1 identifies D\P data. 



AREA NODC ocean area code. 



CLOUD T/A (B) Cloud type according to U'MO code 0500 and cloud amount according to ^ MO code 2700. 



\l a%e observations 



DIR Direction from which dominant waves are coining in tens of degrees according to ^X MO code 0885. 



HGT Height of dominant waves according to \^ MO <ode 1 555. 



PER Period of dominant waves according Ig tt MO code 3155. 



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



CL/TR (B) Water color according to forel-Ule code. Transparency in meters as determined by Secchi disc. 



Vt'IND DIR (B) Direction from which wind is blowing in tens of degrees according to U MO code 0877. 



U IND SPD (B) \*'ind speed in knots. 



U'lND FOR (B) Wind force in beauforl code. 



Vt FATHER (B) \l'eather code — If preceded by letter X is according to \^ MO code 4501 . A numeric two digit entr) indicates weather 



according to \^'M0 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 S(JUARE Two-degree squares — modified Canadian system. 



1 S(^UARE 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 day. 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 carrying 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. 



SIGM A-T (B) Seawaler density anomaly Io2 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. 



D^ NDPTH 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 deplh-pressure term is 



u»^ for stations rtol beginning at the surface). 



OXYG (B) Oiygen in ML/L lo hundredths.
