REMARKS ABOUT THE OCEANOGRAPHIC DATA 



Auxiliary station JJ_ata| 



Weather; Recorded according to the ww (present weather) 

 code as it appears in the seventh edition of the U S, Weather Bureau 

 Circular M, Instructions to Marine Meteorological Observers., Parts 

 of this code are changed m the 8th edition of the Circular M now in use. 



Wind velocity; Measured using an anemometer located 

 30 m a above the sea surface D The observed direction is that from 

 which the wind was blowing, given in degrees measured clockwise 

 from north 



Tabulated data; 



The surface temperature was observed to the nearest 

 tenth of a degree,, The hundredths digit appears always as a zero 

 and has no significance,, 



On some stations, the "surface" Nansen bottle was lowered 

 beneath the surface to avoid striking the side of the rolling vessel,, On 

 these stations, the minimum recorded observed depth is that of this 

 top bottle in the cast as no bucket sample was taken,, 



Paired protected thermometers were used at most depth» 

 When the corrected values are o 05°C o or more in disagreement, the 

 depth of observation is listed twice so that both temperature values 

 may appear „ 



Pairs of determinations of inorganic phosphate concentra- 

 tion were made for each sample. If the two values of extinction differ 

 by more than „ 05 (i„e„ , by more than approximately „ 20 ug at/1) the 

 depth of the sample is listed twice so that both values of inorganic 

 phosphate concentration may appear,, 



Values enclosed within parentheses have been extrapolated 

 to their designated depths,, 



Cruise 5: 



The surface temperature was measured using a bucket 

 thermometer,, The thermometer used during cruise 5, stations 1 

 through 28, read . 2°C too low so that a + 2°C„ correction must be 

 added to the values listed to obtain the correct surface temperature. 

 A + S 1°C = correction must be added to the surface temperature values 

 listed for Smith cruise 5, stations 29 through 51„
