P16A_P17A bathymetry:

ASCII navigation and bathymetry data file was obtained from 
Frank Delahoyde from ODF on 9/27/98.  (Cruise known as Juno 1.)
The depths were Carter corrected, using a 1500 m/sec initial sound speed
from the PDR. 
The gdc format file here thus contains only the Carter-corrected values.
