The data described above are presented in table 8, which, 

 includes all stations at which salinity samples were taken at 

 subsurface depths. Table 9 summarizes all simultaneous 

 surface temperature and salinity observations as well as the 

 time and location and the computed a f Twenty-five of these 

 surface samples were taken in the antarctic; the other fourteen 

 observations were taken en route to the equatorial region. 

 A salinity of 32.90, the lowest surface salinity experienced 

 within the antarctic region, was found to exist very close to 

 the pack ice. The maximum salinity found in the antarctic re- 

 gion was 34.07. The increase in surface salinity in mid- 

 latitudes is shown by the observations made on the voyage 

 northward to the equatorial region.
