NOTES ON TABLE 8, TABULATED OCEANOGRAPHIC DATA, HMS 30 



Where more than one cast was made on a station, they are divided in the observed 

 data by a horizontal line, and the cast number indicated by Roman numerals. 



Where the corrected paired protected thermometer readings differed by more than 

 0.05 C. , the dep'th and salinity are repeated, and both temperature values are carried. <r and 

 S calculated using each temperature value are carried. 



Weather is recorded in the ww (present weather) code given in the U. S. Weather 

 Bureau circular M, eighth edition, Manual of Marine Meteorological Observations. Cloud 

 coverage is in tenths of sky. 



Wind velocity was measured with an anemometer 30 meters above the sea surface. 

 The direction (given to the nearest 10 ) is that from which the wind was blowing, measured 

 through 360 from north. 



In the tabulated interpolated data, values within parentheses indicate extrapolation 

 beyond the depths of observation. 



The following abbreviations, when appended to values or lines in the tabulated observed 

 data, have the indicated meanings: 



Q .- The value seems questionable, but was used in construction of the station curve. 



P -- The value is poor, and while carried was not used in drawing the station curve. 



NG -- The value is obviously in error, and is dropped from the tabulations. 



NS -- No water sample was available for this determination. 



PT -- Nansen bottle pretripped, and data are unuseable.
