EXPLANATION OF DATA SHEETS AND TABLES 

 Oceanographic and Chemical 



Each of the items appearing on the 

 station data pages is explained below. All 

 doubtful data are indicated and were not 

 used in the construction of the curves from 

 which the interpolated values (standard 

 depth values) were derived. Observed values 

 which were obviously false were omitted 

 entirely. A dash in a table means that no 

 value was available. Interpolations for 

 standard depth values for temperature, salin- 

 ity, sigma-t, and oxygen were IBM calcula- 

 tions; those for the chemical constituents 

 were derived from straight lines between 

 observed values. 



The profiles of salinity, temperature, 

 and density were prepared from these data, 

 and appear as figures 5-19. 



1. Cruise Number . The first cruise over 

 the established station pattern (fig. 

 1) was numbered Gill 1, and subsequent 



10. 



cruises, Gill 2 through Gill 9 (only 

 Gill h is covered by the present 

 report) . 



Station Number . Stations are numbered 

 consecutively, starting with one, at 

 the beginning of each cruise. The sta- 

 tion pattern and numbers as shown in 

 figure 1 were maintained on each cruise. 

 if a station or series of stations was 

 not occupied, these station numbers are 

 omitted. Regular stations have numbers 

 only; standard and special stations are 

 specifically indicated. 



Date . Month, day, and year are given. 



Latitude and Longitude . The position 

 of the station is given in degrees and 

 minutes . 



Time . Given in Greenwich Mean Time and 

 is that hour nearest to the start of 

 the first cast. 



Depth . Is the observed uncorrected 

 sonic sounding for the station, recorded 

 in meters. 



J. 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 this scale 

 and calm is 00. Sea table 1, "Compass 

 Direction Conversion Table for Wind, 

 Sea, and Swell Directions." 



Barometer . The barometric pressure is 

 coded in millibars, neglecting the 900 

 or 1000. Thus 996 millibars is coded 

 as 96 and 1008 millibars is coded as 

 08. 



Air Temperature . Dry bulb and wet bulb 

 temperatures are entered to the nearest 

 tenth of a degree (centigrade). 



Humidity . The percent of humidity is 

 coded directly. 



11. Weather . Weather is coded as indicated 

 in table 2, "Numerical Weather Codes - 

 Present Weather. " 



12. Clouds. Cloud type and amount are
