Depth(ni) Depth to nearest meter. A postscript T indicates depth was obtained thermo- 



metrically; Z 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.
