    Note:
    I've placed final pdf and txt versions of the cruise report:
       JOIS97_18SN19970924do.pdf, JOIS97_18SN19970924do.txt
    into the directory:
       http://cchdo.ucsd.edu/data/co2clivar/arctic/JOIS97/JOIS97_18SN19970924/ .
    It includes all the reports provided by the cruise PIs, summary pages, CCHDO data processing notes and internal links to figure, tables and appendices.
    
    It is already available online as it replaced an older file with the same name. 
    
    The previous (preliminary) pdf doc was renamed and moved to the original directory.

    "Notes on Dec 10, 2010 correction to JOIS 97 Leg 4 CTD Exchange file  
    and Summary file.    101210/dm
    
    1. Found Summary File time problems. Stations 1-4 times from computer- 
    generated a97.sum file dated Oct 17, 1997 and Console Operations Log  
    (ConOps) agree within a few minutes.
        Stations 5-16 have Start Down Time(BE) the same as Start Up  
    Time(BO).
        ConOps times were handwritten by the Console Operator.
        Computer times were BE: first recognizable conductive reading.
                            BO: first decrease in pressure after maximum  
    pressure reading.
                            EN: loss of conductivity readings.
        Used ConOps reading for Stations 5-16 BE.
        Station 16 BO and EN values differed by more than a few minutes.  
    Used ConOps times for all Station 16 times.
            Event
             Code   ConOps   Computer   Used
               BE    1640      1700     1640
               BO    1706      1700     1706
               EN    1757      1736     1757
    
    2. Changed first line Date Stamp from multiple entries to single entry  
    "CTD,20101210CCHDOSIODAM"
        Corrected times to Start Down time (BE) per new Summary file."

    Notes on Louis St-Laurent cruise JOIS 97 Leg IV   Expocode  
    18SN19970924     101119/dm
    
    1. CARINA bottle data file posted Sept 1, 2010. (Date Stamp  
    20081215PRINUNIVRMK)
    
    2. Header notes modified Sept 15, 2010:
        Chief Scientist: "Jim Swift" vs "F. McLaughlin, K. Faulkner"
        Faulkner misspelling corrected to Falkner.
    
    3. CARINA bottle file missing TIME, CTDSAL, CTDOXY. Some SALNTY appear  
    to be CTDSAL.
        Changed bottle numbers on CARINA file Station 13 Casts 1 & 2 to  
    match ODF bottle numbers.
          (e.g. Cast 1 changed from 5-40 to 1-36, bottom-top.)
    
    4. ODF bottle file(dated Dec 16, 1997) has slightly different  
    nutrients, CFCs, TCARBN and ALKALI. No TCARBN or ALKALI flags.
    
    5. Assume ODF file has best CTD, oxygen and nutrient data and CARINA  
    has best CFCs, TCARBN and ALKALI.
    
    6. Merged CARINA CFCs, TCARBN and ALKALI into ODF bottle file.
    
    7. ODF/TIC (C. Mattson) Preliminary Cruise Report says departure  
    Tuktoyaktuk 18 Sep 1997.
        ODF unsigned 25 page Preliminary Cruise Report says departure  
    Tuktoyaktuk 20 Sep 1997.
        CARINA file used EXPOCODE 18SN19970924.  (Date of first station)
    
        Used Expocode 18SN19970924 since it has been previously used.
    
    8. Made WOCE and Exchange format CTD files from ODF files dated Oct  
    17, 1997.
    
    9. New WOCE and Exchange format bottle and CTD files posted on website  
    Nov 19, 2010.
