Deployment-specific acquisition description

   PI:              John Morrison
   of:              North Carolina State University
   dataset:         APFZ Mixed Layer Depths
   dates:           October 23, 1997 to November 18, 1997
   location:        N: -56.9998  S: -62.341  W: -171.9  E: -168.0622
   project/cruise:  AESOPS/KIWI6 - APFZ Survey Cruise 1
   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.
