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. Aug. 1964, supplement issued May 1966). 



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

 self-explanatory are described below. 



Depth to bottom Corrected or uncorrected sounding in meter. 



Max. depth of samples Depth of deepest sample to nearest multiple of 100 meters. 



Wave observations: 



Dir Rounded to nearest multiple of 10 degrees. 



Hgt In increments of V2 m. Sum of 5 meters plus increments of V2 m if 50 is added to 



direction. 



Per If numerals 2 through 9 are entered, period in seconds is twice the numeric entry or 



2x (numeric entry) +1. For other entries see WMO Code 3155. 



Sea Sea state according to WMO Code 3700. 



Weather code If preceded by X, weather according to WMO Code 4501. If a two-digit entry, weather 



according to WMO Code 4677. 

 Cloud code: 



Type Cloud type according to WMO Code 0500. 



Amount Cloud amount in eights. Entry of the numeral 9 indicates cloud amount could not be 



estimated. 

 Water: 



Color code Color according to Forel-Ule scale. 



Trans Transparency in whole meters as determined by Secchi disc. 



Wind: 



Dir Rounded to nearest multiple of 10 degrees. 



Speed or force If preceded by letter S, wind spead in knots; if preceded by letter F, wind force 



according to Beaufort scale. 



Barometer Barometric pressure given in 10, units and tenths of millibars. 



Air temp. °C Air temperature to tenths of a degree centigrade. 



Vis. code Visibility according to WMO Code 4300. 



No obs. depths Number of observed levels associated with the station. 



Messenger time Entered in hours and tenths of an hour GMT. For Nansen casts, indicates time of 



release of messenger applicable to the observational level. For STD casts, indicates 

 the starting time of lowering the sensor. 



Card type OBS designates observed levels. STD indicates the values at this standard level were 



interpolated by a modified 3-point LaGrange formula. 



Depth (m) Depth to nearest meter. A postscript T indicates depth was obtained thermometrically ; 



Z indicates uncorrected "wire out" depth. Postscript Q indicates value was marked 

 doubtful by originator; P indicates value was considered doubtful by NODC. Post- 

 scripts P and Q retain this meaning throughout the following entries. 



T°C Temperature to hundredths of a degree Celsius. 



S °/„„ Salinity in parts per thousand. 



Sigma-T Entered to hundredths. 



Specific-volume Multiply entry by 10 ' to obtain specific-volume anomaly in cubic centimeters per gram. 



2aD Dyn. M. XlO^ Multiply entry by lO' to obtain anomaly of dynamic height in dynamic meters refer- 

 enced to the sea surface.
