  • New PDF and Text versions online Jerry Kappa

    Date: 2012-04-26
    Data Type: CrsRpt
    Action: Website Updated
    Note:
    I just added new text and pdf versions of the cruise report to the /data/repeat/atlantic/ar21/ar21_a/ directory.  Changes/additions include:
    
    1) complete NOAA Data Report
    2) CCHDO Data Processing Notes
    3) CCDO-generated station location maps
    4) Standard CCHDO summary pages
    
    The new text version is already online since it replaced an earlier version of the same name.
    The new pdf version will be available online following the next update script run.
    
    The old text version was renamed and moved to the Original directory.

    Notes on AR21 Leg 1 bottle data   EXPOCODE 3175MB91   110309/dm
    
    1. Original bottle data received from Bob Key as AR21a.leg1.Z on January 5, 2005.
    
    2. pH and DOC have no quality flags. Used flag 2 for pH and DOC values.
       Used PH_SWS and PH_TMP = 25 Degrees per README.AR21a.
    
    3. CASTNOs do not match Summary file cast numbers from CTD data and  NOAA Data Report ERL AOML-24(dated April 1994) 
       Bottle file has Station numbers: 8, 14, 20, 25, 30 and 32. Not on CTD file Summary file or Data Report.
       Changed bottle data file cast numbers from all "1"s to CTD and Data Report station and cast numbers.
       Data Report has Station 38 for casts 31, 32 and 33. CTD and AR21a.leg1.Z have casts 32 and 33 in Station 39.
        Station 38/31 is more than 1400km from casts 32 and 33. Casts 32 and 33 have same position and bottom depth.
        Used Station 39 for casts 32 and 33.
    
    4. Bottom depths in AR21a.leg1.Z file differ from bottom depths in Data Report.
       Used Data Report bottom depths to Summary file.
    
    5. Compared Summary File to Data Report and made following corrections assuming Data Report is correct:
       Station Cast 
          2    2   Changed Longitude from 36 10.80 W to 35 10.80 W
          5    5   Changed longitude from 25  0.60 W to 25  0.00 W
          9    8   Changed latitude from  0  0.60 S to  0  0.00 S    
         11   10   Changed latitude from  2  0.00 S to  1 59.40 S
         11   10   Changed longitude from 24  0.00 S to 25  0.00 W
         18   15   Changed latitude from 11. 0.00 S to 10 59.40 S
         18   15   Changed longitude from 25  0.60 W go

    "Notes on Malcolm Baldridge cruise July 11 - Sept 2, 1991.   Expocode  
    3175MB91       110210/dm
    
    Section ID AR21  per Documentation file.
    
    1. Summary file dated 20021029 failed sumchk test.
        WOCE SECT column was blank.  Added AR21.
        LONGITUDE not Left Justified.  Realigned longitude values.
        sumchk okay.
        Stations 1 - 31 plot on African continent. Original summary file  
    (ar21_asu_replaced20021030.txt) shows longitudes negative - West not  
    East.
        Changed longitudes from E to W.
    
    2. WOCE format CTD files are named "CAST-0cc.CAL" where cc is CASTNO  
    in summary file.
        Renamed CTD files to WOCE CTD filename format: AR21_a00ss.wct  
    where ss is STNNBR.
    
    3. First 9 casts had end-of-line "*" in wrong column for 2nd line.   
    Corrected.
    
    4. Removed "_1 _2" between EXPOCODE and WHP-ID to make EXPOCODE agree  
    with summary file.
    
    5. NUMBER OBS. column not lined up properly. Moved one space to right.
    
    6. Converted CTDOXY ML/L to UMOL/KG.
    
    7. No bottom depth.  Used 99999 in summary file to make exchange file,  
    then changed summary file to -9 and exchange file bottom depth to -999.
    
    8. No quality flags in original data set. Apparently all flags set to  
    "2" in 2002-10-17 WOCE format CTD file. Left flags unchanged.
        Note caution in Documentation file re CTD Oxygen data.
    
    9. Made Exchange and NetCDF format CTD files. Checked with Java  
    OceanAtlas."

    Data Type: DELC13/DELC14
    Action: Submitted
    Note:
    Here are the similar (to AR21_1993) files for AR21a (leg 1 and 2 separate). I also attach my README as well as the NOAA final report. Nutrients and oxygen from these early 90s NOAA cruises tend to be below WOCE standard. This cruise pre-dated development of CRMs for carbon, so final calibration on those data are not as accurate as we'd expect today.

    Note:
    On the same page you have listed the 1991 M. Baldrige cruise. Under the data link there is no bottle data. These data are public and i have a copy of everything with WOCE flags added. I can provide a copy if you need it or alternately, it should be available from Kozyr at  CDIAC.
              
  • SUM created, Lat/Lon converted from decimal values Karla Uribe

    Date: 2002-10-30
    Data Type: SUM
    Action: Website Updated:
    Note:
    Sumfile was created from a CSV file that was found in the CTD zip. Lat/Lon data was converted from decimal values. Sumfile in WOCE format.
              
  • CTD converted to WOCE, unformatted SUM put online Karla Uribe

    Date: 2002-10-17
    Data Type: CTD/SUM
    Action: Website Updated:
    Note:
    CTD was converted to WOCE format using the header information, documentation and sumfile. The original CTD zip contains a file called LOCATION.CSV which is a sumfile, I put a copy of that file on the website. That sumfile is still unformatted and it is required to finish testing the CTDs. The original CTD files contained 3 OXY values, the ML/L was selected to be put in the WOCE format which means those units must be converted before converting to exchange.

    Note:
    Database does not reflect having BOT in. DOC is for CTD only. Correct database to indicate BOT is in and all params. WOCE fmt all files. Create SUM. Create exchg.
