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
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!
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.
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.
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.

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.

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.
CTD has been converted to exchange using the new code and put online.
Merged July 2001 CFCs into bottle file, made new exchange file and placed both on web. Helium and Tritium are now public. Notes on P14N CFC merging Sept 28, 2001. D. Muus 1. New CFC-11 and CFC-12 from: /usr/export/html-public/data/onetime/pacific/p14/p14n/original/20010709_CFC_UPDT_WISEGARVER_P14N/20010709.173146_WISEGARVER_P14N/20010709.173146_WISEGARVER_P14N_p14n_CFC_DQE.dat merged into encrypted SEA file taken from web Sept 26, 2001 (20000628WHPOSIODMB) Helium & Tritium data confirmed public by Zafer Top Sept 26, 2001, so newly merged file need not be encrypted. All "1"s in QUALT1 changed to "9"s and QUALT2 replaced by new QUALT1 prior to merging. 3. Exchange file checked using Java Ocean Atlas.
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.
Zafer - Is it safe to assume that all WOCE One-Time Survey neon data from you are now public? Jim Yes they are. Zafer
CTD and Bottle files in exchange format have been put online
6/20/01 CTD Email Data Update Mary Johnson Yes N/a 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. ======================================================================== DATA SETS AFFECTED: WOCE Final Data - NEW RELEASE AVAILABLE: WOCE Section ID P.I.

An oceanographically-insignificant error in CTDTMP data for this cruise has been found (ca. -0.00024*T - 0.00036 degC). A data update is forthcoming. In the interim the corrected data files can be obtained from: ftp://odf.ucsd.edu/pub/HydroData/woce/crs
They seem to have numbered cruises from launch in1991. As the ship schedule for 1993 shows them as two separate cruises (both under Roden) it makes sense to go with the 23 24 numbering you have Jerry.

And would like the following done to the data: Merge data, update data files
Bottle: (tcarbn, alkali, ph, qualt1, qualt2) Carbon data sent by Alex Kozyr on 2000.05.09 was merged into current bottle file. Original data file sent by Kozyr had incorrect header on both TCARBN and ALKALI and needed editing (as per his email). One version of merged bottle file was encrypted and one version had he/tr data masked out (public file). All files and tables were updated to reflect the new values. Merging notes are located in README file in "original" subdirectory for this line.
I have put the final CO2-related data file for the Pacific Ocean WOCE Section P14N to the WHPO ftp INCOMING area. There are three CO2 parameters in the file: Total CO2, Total Alkalinity, and pH (measured @25deg.C) with quality flags. Please let me know if you received the data okay. I still owe you P6E,W,C carbon data, but I do not have any words from Doug Wallace yet. Marilyn Roberts from NOAA/PMEL will send you their data from P16N, P18, and P14S15S cruises soon. So, we almost done for the Pacific.
Because it appears that Sarliee reformatted a version of the bottle file that had parameters "masked out" (which means that they were replaced with 9's) and not encrypted, and the old file which contained all the original values was not clearly marked, the file called p14nhy_ALL_PARAMETERS_1998.11.24.txt was reformatted according to her comments below, run thru wocecvt with no errors and renamed p14nhy_ALL_PARAMETERS_1998.11.24_edt.txt. This file which appears to have all current values in it was then copied to p14nhy_2000.01.11_usd_to_mask.txt. This file was copied once, had helium and tritium data masked out and was moved to the parent directory and renamed p14nhy.txt. p14nhy_2000.01.11_usd_to_mask.txt was also encrypted to make the new nonpublic version of the entire data set, renamed p14nhy.asc and moved to the parent directory. p14nhy_2000.01.11_usd_to_mask.txt is the most recent version of the bottle file at this date in time!
moved current .hy file to original/p14nhy_moved1999.04.06.txt moved current .su file to original/p14nsu_moved1999.04.06.txt_ANDERSON/P12 or P14N.
I have reformatted P12 (S04, SR03, PR12). Arnold is DQEing that line now. I have reformatted P14N. George will DQE that line next. .sum *Changed EXPOCODE from 325023/1 and 325024/1 to 325023_1 and 325024_1. *Adding and/deleting columns to make conform with the WHPO standard format. *Added time stamp. *Ran over sumchk with no errors. .sea *Changed EXPOCODE from 325023/1-24/1 to 325023_1-24_1. *Format looks ok *Added time stamp. *Ran over wocecvt with no errors.
Your data (both bottle and ctd) files are now unencryted on the WHPO website. The CFCs, Helium and Tritium values have been removed and we would like to know if these parameters should be included in the public bottle files.
