NOTES ON TABLE 4, TABULATED OCEANOGRAPHIC DATA, HMS 27 



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. 



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 cover is in 

 tenths of the sky. 



At stations 1 through 38 the wind velocity was measured with an anemometer approxi- 

 mately 15 meters above the sea surface. At the remainder of the stations, they were estimated 

 according to the Beaufort scale and were converted to speed using range of the Beaufort force 



given in the Manual of Marine Meteorological Observations , circular M, table 3. The direction 



o o 



(given to the nearest 10 ) is that from which the wind was blowing, measured through 360 from 



north. 



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

 have the following 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 was dropped from the tabulations. 



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