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. 



Depth to Bottom Uncorrected sounding in meters. 



MAX. DEPTH OF SAMPLES Depth of deepest sample in hundreds of meters to nearest hundred-meter interval. 



(if 2 digit code) 

 or 

 DNP (if 1 digit code) For internal use only. 



Wave observations 



DIR Rounded to nearest multiple of 10 degrees. 



HGT Increments of '/2m. Sum of 5 meters plus increments of Vi 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) -1-1. 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 eighths. 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 Letter S, indicates wind speed in knots. 



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



Air Temp. C Air temperature to tenths of a degree Celsius. 



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.
