 Sampling Methodology
 DMO note on calculated depth

 AESOPS Investigators, Please note:
  Begin and end parameters for time, latitude and longitude are
  provided in the core CTD and Bottle data.  Investigators
  submitting data related to CTD/Bottle casts are urged to use
  the single lat/lon entry from the Chief Scientist's event log.
