    Notes
    Expocode: 317519930704
    Ship: Malcolm Baldridge
    Woce Line: A16N
    Note: Updated version of bottle file with new parameters. Note that this cruise is currently NOT available via the "one time survey A16N" link. It is reachable only via the AR21 (repeat) link. I think the same is true for the OACES91 data. I recommend that the AR21 location be deleted and the AR21 cruises moved to the A16 location.
    
    This file has corrections in addition to new parameters.

    I've added WOCE flag 2 for all CTD data. No flags were submitted but

    Note:
    I updated the CTD netcdf file for http://cchdo.ucsd.edu/cruise/3175MB93.
    The CTD netCDF contained corrupt QC flags because no flags were
    submitted. I have only removed the QC flags.

    Date: 2005-12-15
    Data Type: CTD/BTL
    Action: Data are Public
    Note:
    I have indeed published a paper on LSW differences along A16N including oxygen analyses in GRL (Johnson et al. 2005) this year using A16N data.
    
    The manuscript on SPMW oxygen differences is not yet out but it will be published (someday) in Prog. Oceanogr. in a special issue.  That manuscript (Johnson & Gruber) has been accepted by the special issue guest editor (I. Yashayaev) and forwarded to one of the two editors-in-chief (D. Quadfasel), but I am not sure just how far along the whole issue is at present.
    
    You can find the 1998 data at the CCHDO under the repeat data (AR21):
    
    http://whpo.ucsd.edu/data/tables/repeat/subs/ar21_table.htm
    
    which is where I got them.  The 1993 data are also listed in that table as residing at the WHPO, but the bottle data are still "not public".  However, you can find them at this web side

  • May be A16N Robert Key

    Date: 2005-04-19
    Data Type: Cruise ID
    Action: Cruise ID confusion
    Note:
    Under Atlantic One-Time cruises WHPO lists the 2003 Ron Brown cruise, but not the 1993 NOAA occupation of this line. Carbon people generally use the 1993 NOAA cruise for the "WOCE" occupation of this line rather than the 1988 Oceanus cruise (which does not have carbon data). I  believe that the 1993 NOAA cruise data should be added to WHPO since the CLIVAR focus is more carbon oriented than WOCE and "change" is paramount. Fortunately, this is easy since Kozry has the data and cruise report online:
    
    See item number 9 at http://cdiac.esd.ornl.gov/oceans/other.html
    
    For what it's worth, GLODAP used the 1993 NOAA cruise as the official "WOCE" occupation of A16N. In our final data set we applied the salinity, oxygen and nutrient corrections derived by V. Gouretski. There were no corrections necessary for any of the carbon parameters.
    
    If you have any trouble at all with Alex's version of the data file, I can provide one in the normal format I send.

    Data Type: Cruise ID
    Action: Recommends Line # change
    Note:
    Based on the WHPO repeat cruise table, this does appear to be the same cruise. The data for this cruise have been public for quite some time so it may be worthwhile to check that the version you have is current. The NOAA people routinely refer to this cruise as OACES93 or A16N with the EXPOCODE you have in the table. This is one of their repeat sections, but the timing of the repeat is further apart than a typical WOCE "repeat" cruise. Presumably that is the the reason I didn't even check this area of your site.
    
    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.

    Action: Believes this should be A16N
    Note:
    On 1/5/05 I submitted to you a copy of the data from the 1993 NOAA occupation of A16N (Malcolm Baldridge, NOAA called it OACES93). I mentioned that the carbon community used this cruise rather than 32OC202_1,2 as the "WOCE era" occupation of this line (the Oceanus cruise did not have carbon measurements). 
    
    In the final data report for that cruise the participants suggested that 7.5umol/kg should be added to the oxygen values.
    The version of the data i sent you included that oxygen adjustment.
    
    The need for an adjustment to the oxygen data was confirmed by V. Gouretski's objective analysis of Atlantic data. He derived an adjustment of 5.05 umol/kg (.116ml/l) for stations 32-83 (no adjustment for stations 1-31). Gouretski also estimated that the phosphate and silicate values needed minor adjustment. None of the Gouretski adjustments were in what I sent.
    
    I don't know the WHPO policy for such situations. It is easy enough to back out the adjustment I made if required. Regardless, a footnote to the oxygen data for this cruise is required (or at least desirable). This cruise has not yet appeared on your Atlantic web page. The CDIAC and NOAA versions of this data do NOT have the oxygen correction applied.

    Action: Submitted
    Note:
    With this message I've attached myAR21b (1993 Baldrige occupation of A16N) files even though you didn't ask. I'm certain that my file is the only copy anywhere that has C14 data and may be the only one with QCed C13. I've also attached my "README" file for this cruise. The files currently at AOML and CDIAC were built from my reworking of their original files as part of GLODAP so I can answer any questions that arise. The only thing that will need to be fixed to create formal exchange format are:column labels, column order  and number of decimal places (my code drops trailing decimal "0"s and/or prints too many decimal places. I included calculated values (depth, theta, aou, sigmax), which you may want to drop and recalculate in case of minor function differences.
    
    Other than the information that is included in my README, you already have posted all the metadata I know about other than a final report (also attached) which I found on the AOML CO2 web site as a pdf file.

      No quality codes in CTD files.
      No bottom depths.
      CTD Cast numbers consecutive through cruise, not by station.
      Used CTD cast numbers in file names. Station numbers are in comments.
    
      No Bottle Number from originator but Bottle quality code is included.
      Sample Number appears to be Rosette Cast # and Bottle #.
      Rosette Cast Numbers are different sequence from CTD cast numbers and
         are also consecutive for the cruise not just each station. Missing 
         rosette cast number probably other event not connected to Rosette and
         CTD work.
      TCARBN was listed in original data as TCO2. 
      PCO2 is PCO2 at 20 deg C.
      In-situ PCO2 is in original data file but not in exchange file. Can
         be calculated from data available in exchange file.
      PH is spectrophotometric pH at 20 deg C
