    Data Type: TRITUM
    Action: Clarification Request
    Note:
    To: Zafer Top
    Subject: P14 tritium value
    
    Hi Zafer - I am wondering about a deep tritium value on P14N, and if you could check to see if it's correct.
    
    It's been quite a long time since we first made the sections, but now we are going over them for the last time before publication.
    
    The value is on station 35, at the bottom bottle at 5861.2 dbar.The value is 0.273.  There aren't any other non-zero tritium values in the deep N. Pacific sections  (but on the other hand, there are very few deep tritium measurements).
    
    I've got the section we've made online, if you want to look.  You could also compare with the other tritium sections in the website

    Data Type: TRITUM
    Action: Data Update:
    Note:
    As odd as it seems that high tritium at 5861db at St35 is analytically normal. One cannot exclude the possibility of contamination during sample collection, or even at the lab during processing, but I have no reason to reject this number. Obviously any user of this datum must excercise caution; it is unexpected, it is alone!
    					
  • Exchange values were 2 decimal points, now 4 Stephen C. Diggs

    Date: 2004-07-07
    Data Type: PH
    Action: Website Updated
    Note:
    I have fixed the code that produces the Exchange files and subsequent NetCDF files. PH is now an F9.4 number. Danie, Jim and I are working on a strategy to re-do all of the files online in the near future. 
    					
  • pH values truncated in exchange file Alexander Kozyr

    Date: 2004-06-29
    Data Type: PH
    Action: Data correction needed
    Note:
    One more thing I forgot to ask you. Andrew Dickson of SIO recently send me a message that for WOCE P14N and P14S sections pH was reported to 2 decimal points in exchange formatted files, but to 3 and 4 decimal points in old WHP formatted files. I did not check other files where pH is reported but I think that it is probably a mistake in that pearl code that converts the data. Could you please check this out. It is very important to have pH reported to 3 or 4 decimal points and many users now copy the data in exchange format. 
    					
  • PH should be reported with 4 decimal places, see note: Robert Key

    Date: 2003-06-24
    Data Type: PH
    Action: Data Update:
    Note:
    According to WOCE specs (WHP90-1, Appendix G), pH should be reported with F8.4 (4 decimal places). In cases where a PI reports fewer digits, they are supposed to append 0s for the less significant decimal places.
    
    I just checked the WOCE site and the "Official" bottle file for P16N has 4 decimals for pH while the "shreadsheet friendly" file has only 2. This is clearly a problem with the latter. The official P14N bottle file has pH-25 with 3 decimals while the spreadsheet file has only 2
    and the header gives no indication of the 25degree scale. At CDIAC P14N reports pH25 to 3 decimals in the .dat file while P16N is reported as pH with 4 decimals. I would guess that the PI only reported P14N with 3 decimals, perhaps because the values were either temperature adjusted or temperature equilibrated and that uncertainty was included. At any rate, in this case, WHP got their values from CDIAC.
    
    I never use the spreadsheet format and recomment that others don't since these files are provided as a courtesy and can have errors or be out of date. Regardless, a note to WHP pointing out the problem with the latter file(s) will result in a correction.
    
    WHP invested a significant effort including carbon system measurements in their records. These data were not WOCE parameters (except for C14), however. The best policy in my opinion is to get hydrography from WHP and carbon data from CDIAC whenever possible. Some of the NOAA cruises exist only at CDIAC and some of the Japanese files are only at WHP, but these are exceptions. Regardless of whether the files  are from CDIAC or WHP, they will never contain the GLODAP corrections, which as you know, are sometimes significant.

    Note:
    Merged revised ODF temperatures into current web bottle file. Replaced CTD files with revised ODF files. New bottle and ctd files now on web with new exchange files. Details in notes file sent to Jerry.
    
    Notes on P14N  merging:
    
    1. Merged P14N CTDTMP and THETA from ODF Revised Temperature file:
    /usr/export/ftp/pub/HydroData/woce/p14n/p14nhyd.zip
    into bottle file (p14nhy.txt 20010926WHPOSIODM)
    
    2. Replaced CTD data files with Revised ODF CTD files with corrected temperatures from:
    /usr/export/ftp/pub/HydroData/woce/p14n/p14nctd.zip
    Changed file names from ssscc.ctd to p14n_0sss.1.wct for Cast 1to p14n_0sss.2.wct for Cast 2
         where sss = Station Number
    	    cc = Cast Number
    to conform to present WOCE file name format.
    
    3. Made new exchange files for CTD and Bottle data.
    
    4. Checked new data file with Java Ocean Atlas.

    Action: Cannot do DQE
    Note:
    I checked my files at ODF for information on P14N.  It would appear that I never got to the DQE work on this cruise.  I got the files and was ready to roll, when I got pulled off ODF work to work for my present boss.  His funding was restored to a level where I could work for him full time and he insisted on it.
    
    I don't know if there is anyone else who could work on this cruise, but I certainly couldn't get to it before August.  I can talk to Jim about this if  you like, but doing the DQE work on this cruise soon isn't likely.

    From: Zafer Top 
    Steve: Yes, you did bug me before about this! All data should have been public since 1998, and if they haven't then they should be!
    
    From Steve Diggs:
    I was asked the following question regarding Roden's 1993 cruise from Fiji aboard the Thompson:
    "Steve,  The table says P14N HeTr are still Non-Public and has both an encrypted file and a public bottle file.  Data History has note from Zafer Top saying neon data is public (Aug 29, 2001) but can see no mention of Helium or Tritium.   Do I need to merge the CFCs into both the Public and Non-Public Bottle files or is there chance that the data is now all public?      Dave"
    
    So, are your He/Tr data for P14N public, or would you like for them to be held as encrypted data?  Please let me know and sorry if we've bugged you about this before.

    Processing error corrected, revised data available by ftp
    
    ODF has discovered a small error in the algorithm used to convert ITS90 temperature calibration data to IPTS68.  This error affects reported Mark III CTD temperature data for most cruises that occurred in 1992-1999.  A complete list of affected data sets appears below.
    
    ODF temperature calibrations are reported on the ITS90 temperature scale.  ODF internally maintains these calibrations for CTD data processing on the IPTS68 scale.  The error involved converting ITS90 calibrations to IPTS68.  The amount of error is close to linear with temperature: approximately -0.00024 degC/degC, with a -0.00036 degC offset at 0 degC.  Previously reported data were low by 0.00756 degC at 30 degC, decreasing to 0.00036 degC low at 0 degC.  Data reported as ITS90 were also affected by a similar amount.  CTD conductivity calibrations have been recalculated to account for the temperature change.  Reported CTD salinity and oxygen data were not significantly affected.
    
    Revised final data sets have been prepared and will be available soon from ODF (ftp://odf.ucsd.edu/pub/HydroData).  The data will eventually be updated on the whpo.ucsd.edu website as well.
    
    IPTS68 temperatures are reported for PCM11 and Antarktis X/5, as originally submitted to their chief scientists.  ITS90 temperatures are reported for all other cruises.
    _______________________________________________________________________
    Changes in the final data vs. previous release (other than temperature and negligible differences in salinity/oxygen):
    
    S04P:	694/03 CTD data were not reported, but CTD values were reported with the bottle data.  No conductivity correction was applied to these values in the original .sea file.  This release uses the same conductivity correction as the two nearest casts to correct salinity.
    
    AO94:	Eight CTD casts were fit for ctdoxy (previously uncalibrated) and resubmitted to the P.I. since the original release.  The WHP-format bottle file was not regenerated.  The CTDOXY for the following stations should be significantly different than the original .sea file values:
    	  009/01  013/02  017/01  018/01  026/04  033/01  036/01  036/02
    
    I09N:	The 243/01 original CTD data file was not rewritten after updating the ctdoxy fit.  This release uses the correct ctdoxy data for the .ctd file.  The original .sea file was written after the update occurred, so the ctdoxy values reported with bottle data should be minimally different.
