Bob Newton comma-separated-value attachment to February 19, 2002, message (with corrected flags) into bottle file from web (20011127WHPOSIOSA)

2. HELIUM and DELHE3 replaced data merged Nov. 27, 2001.                  

3. NEON data left unchanged.                                             
 
4. TRITUM data are new.

5. New data file has values for following samples not in current bottle file, so not used:
Station Cast Sample
		  2      3    18
		  2      3    19
		17      3    17
	  29      3     1

6. New data file has quality code "2"s with missing value indicators -999 on two HELIUM samples:
Sta  Ca  Smp   
 57   3   12 
 97   3   23
   Changed quality codes to "5"s.

Attached is a comma-separated-value worksheet with the P9 tritium and helium data from the LDEA Env. Tracers Lab. In a few moments, I will send a second copy, in .xls (Microsoft excel worksheet) format, just in case. There are some "extra" fields that are not part of the WOCE official dataset.  Dave and Steve: you probably just want to delete:

% Bottle ID  (this is an internal tracking number I'm using)

He4ccSTP and He4er_ccSTP - in the lab we don't use NMOL/KG.
I've converted the values, and they are in the standard WOCE units in a neighboring column.  But, just in case, I've left the unconverted values.

Age y - this is the tritium-helium age.  Its not a WOCE variable, but as long as we calculated it, I thought Lynne might find it useful.


Subject: Re: P09 tritium and Helium merging

Thanks Dave!

Each of those 6 records turns out to be a valid measurement. They were mis-identified in our database as a result of typos when the samples were brought into the lab.  I've tracked back the measurements; and recalculated the various quantities (some of which require getting the associated tritium and helium values matched to each other).  I'm sending you the corrected records in two small (6-record) spreadsheets.  The spreadsheets should be identical, except that one is in MS Excel format .xls, and the other is comma-delimited, .csv.

You should:

Ignore/delete the eronneous records that you have discovered. Overwrite the various missing data from the records I'm sending you, with the data in the attached spreadsheets.

The file:  p09_trhedata_LT_2.tab - 43946 bytes has been saved as:  20020102.150426_NEWTON_P09_p09_trhedata_LT_2.tab in the directory:  20020102.150426_NEWTON_P09

The data disposition is:   Public

The bottle file has the following parameters:  TRITUM, DELHE3 ,DELHE4

The file format is: Plain Text (ASCII)

The archive type is: NONE - Individual†File

The data type(s) is: Bottle Data (hyd)

The file contains these water sample identifiers:
Cast Number (CASTNO)
Station Number (STATNO)
Bottle Number (BTLNBR)

NEWTON, BOB would like the following action(s) taken on the data:  Merge Data

Any additional notes are: L. Talley received this data from Bob Newton and is submitting it via this form.

Notes from Newton on the format and information: Hi Lynne, Attached are two versions of the data file.  The data should be identical, the differences are that: The .xls file is an excel worksheet, and has color-coding for duplicates (light blue), good dups (green) and questionable data (red).  The .tab file is tab-separated ascii data, with no color coding. Both files have a "dup" flag (2 = duplicates, 1 = not); and questionable data flags (0 = good, 1 = questionable) for tritium and helium. We didn't flag the helium 3 and 4 separately. Bad he-4 will always have some (albeit typically small) affect on the del-he-3 values. Note that in looking over the plots, Peter and I found 3 or 4 more questionable points, so please delete the excel file I sent you previously. (No loss in data, just better flagging.) In a separate e-mail I will send you the plots we've got of several variables, in jpeg format.  Probably the most interesting one is where we overlay density anomaly contours on the tritium data. We're still rather at a loss to explain the "blobs" of tritium; ... maybe the answers lie on P10? I'm using matlab to look at these things. If you folks do as well, I can perhaps save you a little time by sending the ascii file I work from (with bad data commented out; good dups averaged, distances calculated...) and the load script. Let me know if you want that.

Please note that majority of the C14 analyses for P09 were made at the AMS facility of  Institute of Geological and Nuclear Sciences in Lower Hutt, New Zealand, but AMS C14 analyses for St.26(27.5N, 135E) and St.41(20N, 135E) were made at the University of Groningen, the Netherlands. Data from these two facilities seem to show discrepancy (see attached .pdf file). Therefore we made an intercomparison experiment among the IGNS, U.Groningen and NOSMAS using a common samples. Unfortunately, the results were not conclusive, but data from IGNS looks more stable than those from U.Groningen, and usually data from IGNS and NOSMAS showed fair agreements.  I will send its reports to you separately by air mail.

The plot showed that the different laboratories had a significant offset. From what I recall, the data at WHP does not totally include this data, but the uncertainties in the reported values are about twice the WOCE spec (8 rather than 4). Most of the P9-sta 26 values look low to me, but if we allow for 2 sigma, the following stand out in deep water (relative to P10 (see attached color ps file for samples with Z>1000dB). There are probably others. I also attached a deep water section plot with my software and the smoothing knob turned up significantly higher than normal (ps....1.ps).

When Masao returns from his cruise, we hope to attack this (and hopefully other Japanese) data set in a more sophisticated manner than used thus far.

PDF version of documentation has been put online.

Created directory in p09/orignal for new files and moved new file to p09 directory. New bottle and exchange files are now on line

Notes on P09 CFC merging Sept 14, 2001.     D. Muus
1. New CFC-11 and CFC-12 from:
/usr/export/html-public/data/onetime/pacific/p09/original/20010907_P09_CFC_UPDT_WISEGARVER/20010907.121249_WISEGARVER_P09/20010907.121249_WISEGARVER_P09_CFC_DQE.dat

merged into SEA file received from web, Sept 7, 2001 (19980914WHPOSIOSA)

No SEA file QUALT2 words so added QUALT2 identical to QUALT1 prior to merging.

.SEA file name changed from p09hy.txt to p09_hy.txt.
.SUM file name p09su.txt and text left unchanged.

2. Exchange file checked using Java Ocean Atlas.

Helium received June 7, 2000: /usr/export/html-public/data/onetime/pacific/p09/original/ 2000.06.07_P9_DOC_SEA/P9HeNe.SEA/P9HeNe.SEA and made public by P Schlosser Feb 26, 2001, are not yet on web bottle file.  (19980914WHPOSIOSA)

The Bottle File has the following parameters: 
OXYGEN,SILCAT,NITRAT,NITRIT,PHSPHT,CFC-11,CFC-12,DELC14,TCARBN

The Bottle File contains: CastNumber StationNumber BottleNumber SampleNumber TAKATSUKI, YASUSHI would like the data PUBLIC. And would like the following done to the data:  correct errors in CFCs (Stn.15,33,66,73) and Nutrients /Total Carbon /C-14 (Stn.66)

following up on bill jenkins's message, i would like to ask you to make public all ldeo woce tritium/he data that have been submitted to you.  because the tritium/he community has not yet finished the final calibration of the data, i might have to apply minor corrections to these data once the intercal. effort has been completed.  our acce work was funded over a 5-year period that ended in 2000.  consequently, this data set is further behind in quality control before submission, but i expect that we will get these data ready soon.

SR3 was never funded in a 'regular' fashion, but i used noaa corc funds to keep the measurements of this sample set moving. i expect to finish the analyses this summer and submit them in fall.

File contained here is a CRUISE SUMMARY and NOT sumfile. Documentation is online.

2000.10.11 KJU
Files were found in incoming directory under whp_reports. This directory was zipped, files were separated and placed under proper cruise. All of them are sum files.
Received 1997 August 15th.

Tritium data will be submitted later (after intercalibration).
 
We hold tritium data for a subset of our He lines only.
