Depth to nearest meter. A postscript T indicates depth was obtained thermometrically; 

 S indicates uncorrected "wire out" depth. Postscript Q indicates value was marked 

 doubtful by originator; P indicates value was considered doubtful by NODC. 

 Postscripts P and Q retain this meaning throughout the following entries. 



Temperature to hundredths of a degree Centigrade. 



Salinity in parts-per-thousand. 



Entered to hundredths. 



Multiply entry by 10-' to obtain specific-volume anomaly in cubic centimeters per gram. 



Multiply entry by IQ-^ to obtain anomaly of dynamic height in dynamic meters refer- 

 enced to the sea surface.
