Remarks about the oceanographlc data 



Weather was recorded according to the ww code as it appears in The U.S. 

 Weather Bureau Circular M, Instructions to Marine Meteorological Observers . 



Wind velocity was measured using an anemometer located 30 m. above the 

 sea surface. 



In the tabulated data, the horizontal line(3) between depths separates 

 the two or more casts necessary during the particular station. 



Whenever there is no doubt concerning data being in error (Nansen bottle 

 pretrip, bottle leakage, etc.), these data are not carried in the tabulations and a 

 footnote is appended. If values are doubtful, but there is no positive evidence of 

 an error, the data are carried with appropriate footnotes. 



When the interpolated and calculated values are shown for greater depths 

 than the observed values, they were obtained by extrapolation using the data from 

 adjoining stations as a guide.
