Codes Utilized — Cont. 



ORTG (B) Orijxiiiiitors reference number in two parts — cruise 



niunber or .3 characters (if year of cruise forms 

 part of cruise number years digits may some- 

 times 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 SQUARIO 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 day. Beginning time for STD is 

 given at fir.st obs depth. 



LVLTYP Type of record at depth indicated. "OBS"— ob- 

 served values for STD recorder = level of data 

 read-out. "STD"— NODC standard interpolated 

 values. "ORG" — Standard or other depths carry- 

 ing non-NODC interpolated values. "LIT"— 

 Interpolated standard depth values used as obs 

 for computational purposes. Note — Wlien 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 ther- 

 mometers). 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 be- 

 ginning at the surface.) 



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