Data History

  • BTL 19 at 1202.8 dbar wrong Lynne Talley

    Date: 2004-04-21
    Data Type: HELIUM/delhe3
    Action: Update Needed
    Note:
    Subject: p17c delhe3 and helium
    
    Hielium and delhe3 on P17C, station 14, bottle 19 at 1202.8 dbar are 0.00.  This can't be right.  (We've had other spurious 0 values in the past, from the originator's files.)  I suggest replacing it with a -9 and -999.  I'll also email Bill Jenkins as I suspect it's his data set, as it's upper ocean.
    					
  • BTL 19 value corrected Danie Bartolacci

    Date: 2004-04-21
    Data Type: HELIUM/delhe3
    Action: Website Updated:
    Note:
    I have changed the helium and delhe3 values in the P17C bottle file at station 14, bottle 19 from 0.0 values to missing values (-9) along with associated flags as per Lynne Talley's email below.
    
    This note was added to the 00_README file in the original directory.  All previous files were
    copied to the original directory and new .csv and netCDF files were generated with no errors.
    All new files link online.

    Sarilee and Dave - I had forwarded this message to whpo in June 2002, from Bill Jenkins.  I'm looking at the delhe3 in p17c right now, and there are still bad values at
      station 29, bottle 1 and
      station 41, bottle 3
    
    Bill says they did not sample or report values for these bottles.
    
    I see this message in the Data History as well.  So I think we had best set these values to -9.  Can you double check that other changes listed here for delhe3 on p17c have been made? (station 123)
    
    When I look at the file at station 123, I see a whole lot of zero values, which would be wrong, and don't see qflags.
    
    Thanks - Lynne

    Hi Lynne. I'm a bit confused and trying to figure things out here. I don't believe we reported a station 29 bottle 1 for P17c. We reported data for bottles 2,4,6,7,9,10,12 and 14 for that station. Same issue for station 41.  We didn't analyze a bottle 3 there. We only reported data for bottles 2,4<=>16,18 and 19.
    
    By the way, negative values for del3He are certainly valid, and should not be set to zero. Zero values for del3He may not necessarily mean a problem, but I'll go through the numbers you listed.
    
    We took some copper tube samples from station 123 (bottles 2<=>17) on P17c. Although the samples were analyzed on the mass spectrometer, the results were not processed appropriately (they slipped through the net) yet somehow got included in the submission. The best thing to do here is to eliminate them for the atlas, and we'll see if we can recalculate them and resubmit them later.
    
    Sample 121-1-8 (160.8 dbar) was underextracted (procedural problem) and should be eliminated.
    Sample 121-1-5 (110.8 dbar) should be fine: the del3He = -0.004% (thus was rounding to zero for you)
    Sample 116-1-4 (80.1 dbar) was not analyzed by us (I don't know how it got in the mix)
    Sample 110-1-9 (212.2 dbar) was a failed analysis and should not have been reported
    Sample 110-1-11 (310.3 dbar) was not analyzed by us for helium
    Samples 80-1-X (82-150 dbar) were not analyzed by us for helium (I don't know why, but they weren't)
    Sample 65-1-4  (73 dbar) wasn't analyzed by us for helium
    Sample 65-1-13  (610 dbar) wasn't analyzed by us for helium
    Sample 54-1-8  (241 dbar)  was underextracted (procedural problem) and should be eliminated
    Sample 48-1-7 (232 dbar) wasn't analyzed by us for helium
    Sample 44-1-14 (601 dbar) was underextracted (procedural problem) and should be eliminated
    Sample 33-1-11 (300 dbar) was underextracted (procedural problem) and should be eliminated
    Sample 21-1-10 (253 dbar) wasn't analyzed by us for helium
    Sample17-2-15 (699 dbar) wasn't analyzed by us for helium
    
    In short, the only one from the bunch that should be kept is 121-1-5 (110.8 dbar). I'm sorry that the other rubbish somehow got entrained in the file. I think it was one of my earlier submissions.
    					
  • Decimal-1 data replaced with decimal-2 data Dave Muus

    Date: 2003-03-06
    Data Type: DELC13
    Action: Website Updated:
    Note:
    Replaced DELC13 decimal-1-data with decimal-2-data from same original data file. 
    
    Notes on P17C              Mar, 5, 2003      D. Muus
    
    1. Two C13 data files have been received:
    
        1) /usr/export/html-public/data/onetime/pacific/p17/p17c/original/
    	2001.12.19_CFC_C13_MRG_P17C_SA/p17c.c13.dat
    	Received May 2001 from Bob Key ftp site.
    
        2) /usr/export/html-public/data/onetime/pacific/p17/original/
    	20010206_C13_P17_STUART.email
    	Received Feb 6, 2002 from Dana Stuart
    
        DELC13 agree within .01 /MILLE and flags agree. Used Bob Key's since
        received later.
    
    2. 1. Replaced 1-decimal-place DELC13 in p17chy.txt (20011029WHPOSIODM)
       with 2-decimal-place DELC13 from:
    
    	/usr/export/html-public/data/onetime/pacific/p17/p17c/original/
             2001.12.19_CFC_C13_MRG_P17C_SA/p17c.c13.dat
    
    
    3. Both QUALT1 and QUALT2 set to QC value given in original data file.
    
    4. C13ERR column was in web bottle with all missing value indicators.
       No C13ERR data in C13 data files.
    
    5. One sample in Stuart data file has 2 extra delc13 values.
    		  STNNBR  CASTNO  SAMPNO  DELC13 QF
                          42       1       7    0.63  2
    	              42       1       7    0.70  2
        First value for 42/1/7 is 0.67, QF=6, in both Key and Stuart Files.
    
    6. Made new exchange file for Bottle data.
    
    7. Checked new bottle file with Java Ocean Atlas.
    					
  • Station 65, samples 8-15 quality flags changed fron 2 to 3 Dave Muus

    Date: 2002-10-29
    Data Type: BTL
    Action: Website Updated:
    Note:
    Changed quality flags for Station 65 Samples 8-15 nitrite from 2 to 3 per Lynne Talley and Doug Masten. Changed all quality flag "1"s to "9"s. Put new woce and exchange format bottle files online.
    
    Bottle NETCDF and inventory updated as well.
    					
  • Data should be flagged as questionable Doug Masten

    Date: 2002-10-28
    Data Type: NO2
    Action: Update Needed
    Note:
    There were a lot of flow (bubble) problems for NO2 on this station. Coincidently (or not!), these problems started with sample #8 and continued through #15, which are the samples you have questioned. The analyst adjusted peaks and baselines at sea, but could EASILY be incorrect. It's hard to tell exactly what they 'should' be, but I would flag them questionable due to all the problems. There are no notes in the Quality file for these samples.
    
    P17s Station 125:
    
    This is easier. Sample #12 is higher than adjacent samples with the peak and baselines OK. Again, no notes in the Quality File; it could be real or possibly contaminated. I would leave it, as there are no analytical problems that stand out.

    Action: Data are Public
    Note:
    It was brought to my attention that the WOCE Paci&#xFB01;c/Indian He-Tr data was  not as yet made public. After submitting it to you last year, I had intended on going through it one more time to ensure there were no problems with it. Unfortunately, I have not had the time to do this. Is it possible, therefore, to release it as public data, and if there are any subsequent minor revisions, to make changes? I suspect there might be a few samples in the set that might have got through our initial quality control.

    I transferred files over to the ftp-incoming directory the easy way (for me)...  You will find the following "new" directories in /usr/export/ftp-incoming on whpo:
    
    	p16a_p17a
    	p17c_p17s_p16s
    	p17e_p19s
    
    I already gave you p19c (which I see is in P19Cdoc).  I thought it was redundant to put long names in every filename, so I made the directory name with the cruise lines, and the files are all the same.  The figs files are all figxx.ps (where xx should indicate the figure numbers referenced in the documentation).  I also included ps and ascii versions of the original documentation and applicable appendices.  (appendix a and b will be missing - they are outdated now and shouldn't be included in anything.)

    You may have tons of questions regarding the following. Hopefully I can answer most of them. I have tried to pare this listing down to a minimum at this point.
    
    Attached are 5 ascii files and one pdf file for P17C LV (a.k.a.TUNES-1):
    
    P17CLV.data - my version of the final data file with all qc flags (this file has a temperature flag (tf) and a pressure flag (pf). The appendix to this report contains all shipboard notes regarding  sample collection, problems, etc.
    P17CLV.sta - my version of the final LV station file 
    P17CLV.pdf - my final data report for P17C LV data
    31WTTUNES1.ldo - original LV report produced by SIO (Sanborn)
    31WTTUNES1.lsu - final version of p17c lv sum file
    31WTTUNES1.lvs - initial version of p17c lv hyd file (no C14 prior to my QC, but close to WOCE format and with all times and locations)
    
    AND
    
    5 ascii files and 1 pdf file for P17C LV (a.k.a. TUNES-3). This cruise was run by WHOI with 1 SIO Tech aboard to help with LV work. As a result, no "official" hyd file was ever created. I got P,T,S data from SIO, nuts from OSU, C-14 from Stuiver and Ostlund.

    P16CLV.sta - my final version of the LV station file
    P16CLV.data - my final version of the LV data file with C14, C13, nuts, and interpolated oxygen. I provided all final QC flags.
    P16CLV.pdf - my final report for this leg. Appendix includes decklog notes, etc. This document failed to get an official OTL report number or data (I use 1/31/97).

    I received the CFC-11/12 datasets for the following WHP lines:
    EXPOCODE        31WTTUNES/2     WHP-ID  P17S,P16S
    EXPOCODE        31WTTUNES/1     WHP-ID  P17C
    EXPOCODE        316N138/12      WHP-ID  P19C

    EXPOCODE        316N138/3       WHP-ID  P6E
    Each file looks fine and has been placed in the proper archived directory on our machine so that they can be merged in with the rest of the values.

    I just ftp'd our cfc files to the /INCOMING/RFine_cfcs directory.  The files named *.sea are hydro files with our final cfc values and quality bytes merged in.  The files named *_cfcs.dat are files that include station, cast, bottle, cfcs and quality bytes.  Please let me know if you
    have any problems and I'll let you know if we have any changes (hopefully not...).

    Note:
    I have provided hyd files for all these cruises, QC'ed by me, albeit not in WOCE format.  I can resend if needed. Other than format, the only strange thing about these files was that I supplied a flag for revtmp, which I think appropriate given the number of things that can go wrong. Lynne may have these files reformatted since she has been using the results in the atlas prep.

    Note:
    Hi Terry. The next message (1000+ lines) contains the tritium-helium data for the TUNES 2 leg. Just to reiterate, this is the Thomas Washington cruise that took place in the summer of 1991, covering Pl7c-Pl6c along 135W and 150W respectively. The data are organized as one line per "sample", which may contain tritium, helium or both. -99 represents no data or sample for a variable. The columns are as follows:
    
    Sta, Cast, Bottle, Pressure (db), tritium (TU), sigma-tritium (TU), delta-3He (permil), sigma-delta (permil), conc-Helium (nM/Kg), sigma-conc (nM/Kg), quall, qual2
    
    The quality numbers for tritium (quall) are
    1 =	valid sample
    2 =	possible under-extraction
    3 =	possible contamination
    7 =	identity suspected
    9 =	no sample
    In this data set, there were no quall values of 2,3 or 7
    
    The quality numbers for helium (qual2) are
    1 =	valid sample
    2 =	possible under extraction
    3 =	possible (air) contamination
    7 =	identity suspected
    9 =	no sample 
    In this data set, there were no qual2 values of 7
    
    Also, the obvious applies, if a sample value is null (-99) its error, which may not appear as null (-99) is meaningless.
    
    Also, the tritium data has been corrected for a small (.0045 TU) blank due to cosmogenic production during storage.
    
    Finally, I was hoping to finish up a paper that I am working on for this data: I don't mind you using it for demonstration purposes, but-I would hope that its distribution could be restricted over the next 4-5 months until I have had a chance to get it submitted and hopefully reviewed and accepted. Also, it will give me a chance to make one final pass at the data to ensure that there are no problems with it. I hope this is OK.
