The data collected during 1955 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 figm-es 13, 

 14, 15, 16 and 19. 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 1/60. Wliere 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 a^ signifies l,000(density-l) 

 at atmospheric pressure and temperature t.
