    Action: Website Updated
    I just added new text and pdf versions of the cruise report to the /data/repeat/atlantic/ar21/ar21_a2 directory.  Changes/additions include:
    1) Expanded CCHDO Data Processing Notes
    2) CCHDO-generated station location maps
    3) Expanded standard CCHDO summary pages
    Both new versions are already online since they replaced earlier versions with the same names.
    The old versions were renamed and moved to the Original directory.

    Notes on AR21 Leg 2 bottle data   EXPOCODE 3175MB91_2   110309/dm
    1. Original bottle data received from Bob Key as AR21a.leg2.Z on January 5, 2005.
    2. AR21a.leg2.Z has no ALKALI data. TALK are in NOAA Data Report ERL AOML-24(dated April 1994) but are calculated data (uEq/Kg) and were not used.
    3. DELC13 have no quality flags. Used flag 2.                       
    4. CASTNOs do not match Summary file cast numbers from CTD data and  NOAA Data Report ERL AOML-24(dated April 1994) 
       Changed bottle data file cast numbers from all "1"s to  Data Report cast numbers.
    5. Bottom depths in AR21a.leg2.Z file differ from bottom depths in NOAA Data Report.                        
       Used Data Report values since they have better agreement with deepest bottle depths.
       For example, Station 4 deepest bottle is 5645m(5765db), Data Report bottom depth is 5908 and data file bottom depth is 3589m.
