the station number, date, geographical position, depth of water, and 

 dynamic height of the sea surface above the reference surface used 

 in the construction of tlie dynamic topograpliic charts shown in fig- 

 ures 45, 46, 47, 48, and 52. For stations 2541 to 2808, inclusive, the 

 sea surface is referred to the 1,000-decibar surface and the depth of 

 water is the uncorrected fathometer sounding based on a sounding 

 velocity of 1,447 meters per second. For stations 2809 to 2847, inclu- 

 sive, the sea surface is referred to the 2,000-decibar surface and the 

 depth of water is the sonic sounding corrected for sounding velocity 

 and draft but not for slope. Where the depth of the scaled values 

 is enclosed in parentheses the data are based on extrapolated verti- 

 cal distribution curves of temperature or salinity or both. Asterisks 

 appearing before observed temperatures indicate that these tempera- 

 tures were determined from the depth of reversal and the corrected 

 reading of an unprotected thermometer. The symbol cr, signifies 

 1,000 (density- 1).
