In charge of data computations and tabulations - Mrs, M. L. Godfrey 



Remarks about the data tabulations: 



Weather was recorded according to the WW code in the U. S. 

 Weather Bureau Circular M, Instructions to Marine Meteorological 

 Observers. 



Wind velocity was measured by an anemometer located 30 m. above 

 the sea surface. 



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

 the two or more casts necessary during the particular station. 



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. 



Measurements of temperature, chemical determinations of salinity, 

 oxygen, and phosphate were made in duplicate and averaged if the values 

 were within the following limits: temperature, above 300 m. , 0.05 C. , 

 below 300 m. , 0. 02 C. ; salinity 0. 04 °/oo; oxygen 0, 1 ml/1; phosphate 

 0.05 |Jig-at/l. Whenever these limits are exceeded, both values are 

 carried in the tabulations. Obviously wrong values, as determined from 

 the station curves, are omitted from the tabulations.
