CTD SBE-19 model 1064 

This instrument was bought in 1992 and it was lost during the cruise WOCE-SR1 
1994, so sensors were  not able to be recalibrated in the meantime to compute 
the shifting of the sensors.

Processing
  Step 1
  1.  Convert data from  *.hex to  *.cnv format using DATCNV program and  *.con   
      configuration file.
  2.  Deleting negatives velocities using the leewoce.bas program 
  3.  Checking and cleaning the header files.
  4.  Computing the average down velocity value (X).
  5.  to apply the Aling CTD program to correct temperature and conductivity 
      time response shift  from the CTD'sensors.

  Step 2
  a)  To apply DATCNV program to average observed values meter by meter.

  Step 3
  a)  To apply  Winfilter program to filter data after step 2 , using a flexible 
      windows determined by the user.

NOTE: All data from WOCE PR14 and SR1 cruises, have been passed to the National 
      Oceanographic Data Center of Chile (CENDOC) for data management 
      purposes and to be quality controlled according to normal WHPO 
      procedures. Once finished they have been sent to the WOCE Hydrographic 
      Program Office at the Scripps Institution of Oceanography for 
      archival. The data remain non-public access  until new notification. 
      However, specific authorisation will be forwarded to interested 
      scientist  if their goals do not overlap SHOA's goals. For major
