Deployment-specific acquisition description

   PI:              John Morrison
   of:              North Carolina State University
   dataset:         APFZ Mixed Layer Depths
   dates:           January 12, 1998 to January 28, 1998
   location:        N: -56.9998  S: -67.7842  W: -170.1117  E: -169.9983
   project/cruise:  AESOPS/KIWI8 - APFZ Survey Cruise 2
   ship:            R/V Roger Revelle
 
   Note:  event 02162111 salts were bad, therefore density was not computed.
   Some station casts were not deep enough to show a mixed layer.
