EXPLANATION OF OCEANOGRAPHIC STATION DATA 



A. General 



Each of the items appearing on the data pages is explained below. The 

 vertical arrows shown in some of the column headings indicate the location of 

 decimal points. The presence of asterisks to the right of data indicates those 

 data are doubtful; hence, they were not used in the construction of the curve 

 from which interpolated values (standard depth values) were derived. Observed 

 values obviously invalid were omitted. 



B. Surface Observations 



1 . Consec . Sta . No . The stations are numbered in the chronological 

 order in which they were occupied and are arranged consecutively in this report* 



2. NODC Ref . No. This number is assigned by the National Oceano- 

 graphic Data Center . It identifies the cruise and provides a means of sorting 

 from the IBM files all cards pertaining to a particular cruise. 



3. Station. Stations are numbered to designate a certain station location. 

 This number is assigned prior to the beginning of the cruise and is the identifying 

 station number appearing on the station location chart. 



4. Date. Month, day, and year are given in Arabic numerals. The hour 

 is Greenwich Mean Time and is that hour nearest to the messenger time of the 

 first Nansen bottle cast. 



5. Position. Latitude and longitude of the station are given In degrees 

 and minutes; minutes rounded-off to the nearest whole number. 



6. Sonic Depth Uncorrected. Sonic Depth is the uncorrected sounding for 

 the station, recorded in meters. 



7. Max . Sample Depth . The maximum depth from which a water sample 

 was obtained at the station is given to the nearest 100 meters. 



8. Wind. Wind speed is given in meters per second. Direction from which 

 the wind blows is coded in degrees true to the nearest ten degrees. The last zero 

 is omitted. North is 36 on the scale and calm is 0. See Table 1, Compass 

 Direction Conversion Table for Wind, Sea, and Swell Directions. 



9. Anemo. Hgt. The height of the anemometer above the waterline is 

 given in meters. 



10. Air Pressure. Barometric pressure of the air is coded in millibars, 

 neglecting the 900 or 1000. Thus, 996 millibars is coded as 96 and 1008 

 millibars is coded as 08.
