    Note:
    The CTD oxygen data were updated after the data book was published by Kawano et al. (2009). In 
    the data book, data from two oxygen optode sensors (Oxygen Optode 3830; Aanderaa Data Instruments 
    AS, Bergen, Norway, and RINKO; JFE Alec Co. Ltd., Kobe, Japan) were combined and used because 
    data quality of the SBE 43 oxygen sensor was relatively bad (Kawano et al., 2009) for the cruise 
    MR07-04. Data from the two oxygen optode sensors were combined because the Optode 3830 had a slow 
    time response without pressure hysteresis and the RINKO had a fast time response with pressure 
    hysteresis. The time-dependent, pressure-induced effect (pressure hysteresis) on the sensing foil of the 
    RINKO was similarly observed in the SBE 43 data. Recently, a correction method of the pressure 
    hysteresis was developed for the SBE 43 (Sea-Bird Electronics, 2009), and the correction method was 
    successfully applied to the RINKO (Murata, 2009). Therefore, the RINKO data were reprocessed, 
    calibrated, and used as the CTD oxygen data for the cruises MR07-04 and MR07-06.

    Action: Website Update
    Note:
    Edited the following:
    
    EXCHANGE BOT FILE
    -------------
    Parameter Header:
    SIG0 to STHETA
    SECT to SECT_ID
    PH to PH_TOT (as per doc file)
    
    Units Header:
    KG and MBQ //CUM to /M^3
    removed UTC (from TIME)
    removed DEG (from Lat and Lon)
    removed M from DEPTH
    
    Added CS137ER to our parameter table
    Added CTDPRS_FLAG_W, CTDTEMP_FLAG_W to our
    parameter groups table (in appropriate order)
    
    First Header:
    edited EXOCODE from 49MR0704_1 to 49NZ20070724
    added name/date stamp
    
    copy_bottle_data.rb was used to place all
    the parameters in the accepted exchange parameter
    order.  File was renamed p01_49NZ20070724_hy1.csv
    File was checked with JOA.
    
    
    WOCE BOT FILE
    ----------
    Parameter Header:
    SIG0 to STHETA
    PH to PH_TOT
    
    Units Header:
    KG and MBQ /CUM to /M^3
    
    Data:
    edited EXOCODE from 49MR0704_1 to 49NZ20070724
    added WHP-ID and name/date stamp
    
    Ran wocecvt, however the file contains many
    non-WOCE parameters which therefore renders
    format checking impossible.
    
    SUMFILE
    -------
    Data:
    edited EXOCODE from 49MR0704_1 to 49NZ20070724
    
    Header:
    added name/date stamp
    
    ran sumchk with no errors.
    renamed file p01_49NZ20070724su.txt
    
    
    WOCE CTD FILES
    --------------------------
    Edited EXPOCODE from 49MR0704_1 to 49NZ20070724
    Edited FLUOR  units from MG/CUM to MG/M^3
    Zipped all files into p01_49NZ20070724ct.zip
    
    EXCHANGE CTD FILES
    ---------------------------------
    Edited EXPOCODE from 49MR0704_1 to 49NZ20070724
    Edited FLUOR  units from MG/CUM to MG/M^3
    Renamed individual station files to adhere to
    exchange file naming conventions.  Zipped all
    files into p01_49NZ20070724_ct1.zip
    
    
    NETCDF BOTTLE/CTD FILES
    ----------------------------------------
    NetCDF bottle and ctd files were generated
    using the respective reformatted exchange
    files, provided by the data originators.  Files
    converted without errors.  Bottle file named:
    p01_49NZ20070724_nc_hyd.zip.  CTD file
    named p01_49NZ20070724_nc_ctd.zip.

    We published a databook of WHP-POI, PI4 Revisit. The data in the databook have
    been submitted to CCHDO and CDIAC, therefore all data and figures in the databook are free
    to use. However, it would be grateful if you refer this databook and kindly inform us when you
    use the data and figures in the databook. Your reference and kind support will surely make
    Japanese government to support hydrographic activities under International Repeat
    Hydrography and Carbon Program.
