THE PRINCIPAL OBJECTIVES OF THE CRUISE WERE:
To collect necessary information to develop ocean circulation models to predict 
decade climatic changes  in order to contribute to international WOCE program.


PRELIMINARY RESULTS

CTD SBE-19 model 1064 

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

TEMPERATURE:
			
A =    3.67532044E-03  slope= 1
B =    5.78042359E-04  offset= 0
C =    9.66296627E-06
D =   -1.12827511E-06
F0= 2335.580

CONDUCTIVITY:
M =  2.6			
A =  1.99268521E-03  slope= 1
B =  4.89685367E-01  offset= 0
C = -4.10744141E+00	
D =  7.48601141E-04	
E = -9.5700E-08		

Pressure
A0 = 4980.989
A1 =   -1.304659E+00
A2 =    7.124232E-08

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 CTDísensors.

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 authorization  
      will be forwarded to interested scientist  if their goals do not overlap  
      SHOAís goals. For major information write to:
