8. From measurements made on samples collected in the Grand 

 Banks region in 1952 and from the section across the Labrador Sea 

 in 1952 and 1953 it is concluded that the concentration of total 

 phosphorous is roughly characteristic of water masses though of 

 doubtful utility as a tracer of water masses. The distribution of 

 phosphorous found in the southern Labrador Sea has been described. 



TABLE OF OCEANOGRAPHIC DATA 



The data collected during 1953 are tabulated below. The individual 

 station headings give the station number, date, geographical position, 

 depth of water, and the dynamic height of the sea surface used in the 

 construction of the dynamic topographic charts shown in figures 14, 

 15, 16, 17, 19, and 37. The depths of water are rough approximations, 

 being uncorrected sonic soundings based on a sounding velocity of 800 

 fathoms per second and containing an additional mechanical speed 

 error of about %o. Where the depths of scaled values are enclosed in 

 parentheses, the data are based on extrapolated vertical distribution 

 curves of temperature or salinity or both. Asterisks appearing before 

 observed temperatures indicate that these temperatures were deter- 

 mined from the depth of reversal and the corrected reading of an 

 unprotected thermometer. The symbol o-, signifies 1,000 (density— 1) 

 at atmospheric pressure and temperature /.
