Depth (m) Depth to nearest meter. A postscript T indicates depth was obtained therometrically; 



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

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

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