t was decided at today's CCHDO meeting to merge or remerge CFCs for all WHP cruises in Mark Warner's CFC DQE file (Southern Ocean WHO lines). This will assure all that the CFCs for these cruises are indeed updated as intended. Danie and Sarilee will attend to this promptly. Danie will see that the sections of greatest urgency to Lynne receive top priority.
The list of cruises in Mark's file was as follows:
A21: EXPOCODE: 06MT11_5
A23: EXPOCODE: 74JC10_1
I06S: EXPOCODE: 35MFCIVA_1
MARGINEX: EXPOCODE: 09AR9604_1
S03_S04I: EXPOCODE: 09AR9404_1
S04A: EXPOCODE: 06AQANTIII_4
S04I: EXPOCODE: 320696_3
S04P: EXPOCODE: 90KDIOFFE6_1
SR04A_A12: EXPOCODE: 06AQANTX_4
SR04_ANTXV4: EXPOCODE: 06ANT15_4
It may be that the CFCs for the following cruises from the list above have already been updated:
> sr04antxv4
> s04p
> a23
> a21
But, to be certain, the CCHDO will update them as well.
As far as why these cruises did not get updated with Mark's DQE'd CFCs, we have no idea. Sorry. All of the other ocean basins' CFCs were updated years ago.

Lynne Talley enquired about the DELC13 and 3 N02 values (see attached emails).
Bob Key sent a file with DELC13 and I remerged it with two decimal places instead of one.
I changed the N02 for sta. 716, samples 6, 5, and 4, at 2818.0, 3179.7, and 3538.7db to 0.01. I had done this previously (see Data History 199/09/23). The bad values were reintroduced when ODF resubmitted the data (2001/06/20) when they discovered a small error in their algorithm to convert ITS90 temp. calibration data to IPTS68.
The 13C for S4P should have normal precision reported by NOSAMS, i.e. not 1 decimal. I have attached the latest version of that data as I received it from them (Dana Stuart) on 8/9/99. These values need to be truncated.
Bob and Sarilee - just checking - is it correct that delc13 values on S4p have only one decimal point accuracy?

Subject: nitrites on s4p
Hi Sarilee - I'm not sure who to check with on nutrients for S4P.
Nitrite on station 716, bottles 6, 5, 4 at 2818,3179, 3538 dbar can't possibly be right (> 2.5 where they should be very close to zero). I think I'm counting quality flags right and don't see anything other than a 2 for the flags for these 3 bottles.
How do we go about resolving this?
Mark Warner submitted a file with updated cfc data. I merged the CFC-11 and CFC-12 from file s04p_cfc_whpo_dat into the online file.
Online file only had QUALT1 flags. Since the cfc file sent by Warner had both Q1 and Q2 flags, I copied the Q1 flags to the Q2 in the online file before I merged the cfc's.
File from Warner had Q flags of 1 for missing data. I changed them to 9.
I ended up sending a tar of all the cruises for which we did the DQC process. In general, the CFC PI agreed with our evaluation and changed their QUALT1 flag to agree with our suggested QUALT2 flag. Please feel free to ask questions. (Fortunately, we had sent all of this data to Alex
Orsi over a year ago, so the atlas is made with this data.)

Any additional notes are:
Miscommunication between myself and Dong-Ha Min have resulted in this delay. I will upload all of the data with itsassigned (and agreed upon with the PI) Qualt2 (q2) and revised q1 characters.
Newly merged S04P files are in ~dave/SDIGGS/S04P. Includes sea file, summary file, exchange file and notes file. wocecvt and Java Ocean Atlas successfully run on new data files.
I believe the CFC-12 section looks good when contoured. The size of the unknown correction due to the poor integration of CFC-12 on a tailing peak is relatively small (I believe). It becomes a real problem when you try to calculate rations for the lower CFC concentrations. You could get away with presenting the section and somehow noting the problem.
I thought we had sent the documentation to WHPO. I better double-check on that.
I have changed the three nitrite values for S04P station 716, bottles 4, 5, and 6 to 0.01 per Jim's e-mail. I also reformatted the .sum file. Usual shifting, adding, deleting columns. I did change the EXPOCODE in the .sum file from 90KDIOFFE6/1 to RUKDIOFFE6_1 to conform with what is used on the web site and in the .sea file (I assume this means we are using RU for Russia instead of 90 which was used for the Soviet Union).
I have put the files on whpo in /usr/export/ftp/pub/WHPO/S_ANDERSON/S04P.
Merged DELC13 data into online file s04phy.txt (20010810WHPOSIODM). DELC13 data were retrieved from Bob Key's ftp site in May of 2001.
Bottle file had a sta. 694 cast 3, but the sum file did not have a cast 3 for sta. 694 (this was noted by Dave Muus (2001/08/07). Dave deleted the cast from the bottle file since it only contained CTD data. Subsequently a new bottle file was put online (2001/08/13) which had the same problem. Cannot create exchange format with this problem, so I deleted sta. 694, cast 3. This problem needs to be resolved.
I created a new exchange file and put it online.
created *check.txt file for the cruise. created *.ps files for this cruise.
CTD has been converted to exchange using the new code and put online.
PDF documentation for this cruise has been put online.
14C was added and made public. ODF updated CTD files and CTD values for bottle files have been added to the website. Sumfile from ODF added to wesbite as well. All files re-linked and checked out. (as per D. Muus note below)

Bottle exchange file was put online.
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.

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
Expocode for sumfile was modified. Expocodes in all ctd files have been editted to match the underscored expocode in the sum and bottle files. New files were zipped and replaced existing ctd files online. Old files were moved to original directory.
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.

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.
Merged DelHe3, Helium, Tritium, and Neon from Hohmann into hyd file. Updated hyd file is on line. Merging notes in original subdir 2000.03.10_S04P_HE_NE_HOHMANN. EXPO codes in sum and hyd file do not match. Notes per S. Anderson (1999.09.23) suggest EXPO code in sum file should be changed. Read-only permission on this file. Please see 00_README notes in original subdir regarding EXPO code:
2000.10.04 SRA
Merged DELHE, DELHER, HELIUM, HELIER, TRITIUM, TRITER, NEON, NEONER.
Split data file S4PHeNeTr.sea into a separate file for each parameter, removed blank spaces (no data) from Neon data.
NOTE: NEON data for station 768 btl 15 had no data (white space) and flag = 2. Changed flag to 9.
I put a copy of the report (S4P.txt) in your INCOMING directory. Unfortunately, my translator strings the tables out (by row) so it is a bit messy and the figures are cut. I do have all of the
figures available as either simple ps or epsi files and could transform into pdf if there is any gain.
S4P was a Schlosser cruise. The official release date for this data is 9/16/2000 which is about the same as the expected release date for the next CD-ROM. It is quite possible (probable) that this omission is my error rather than WHPO (I'm more hesitant to submit other's data and this may have fallen through the cracks in the process). Assuming this to be the case, I have attached an ascii version of the final data (S4P.C14).
My data dump software isn't picky about format, so extra decimal values can be rounded to WOCE specs and any truncated too short can have O's added in the decimal field. otherwise, the data is to WOCE specs. I have also attached two versions of the final C14 report for this cruise (S4P.Cl4.pdf and S4P.C14.ps). The report is similar to previous final reports, has an OTL Tech Rep. # for reference, includes color figures, and is also accessible via the GLODAP web site. This cruise can now be listed as WHPO-RAW.
I have talked to Steve regarding the LVS and I believe he is working on them.
On the upcoming CD-ROM release it would be nice if the C-14 data could somehow be linked to the various Final Reports.
Hi Bob,
Just letting you know your 3 files (one data file, 2 doc files) made it across the ether and look fine. The data file has the following header:
Station,Cast,Bottle Number,Pressure (dB),Delta C-14 (0/00),c14e,c14f and includes stations 682 - 794.
The pdf doc file has 11 pages, which we will insert directly into our online pdf doc for s04p. One question. Do you have a plain text file for this report that you could send?
Jerry
The 3 files described in my e-mail of earlier today have been ftp'ed to the whpo INCOMING directory.
- bob
Please change all designations of "RU" to "90" for the Russian cruises. We agreed on this a long time ago.
S04P Neither myself nor Jerry could find any documentation that these data came in, nor the data file itself. I will ask Steve about this one ASAP.
Hi All- I have merged Alex Kozyr's CO2 data into the WHP S04P bottle file. Merged were total carbon, pco2 and pco2 tmp. Old bottle file has been moved to the original directory and replaced
with the new merged file. All tables and entries have been updated to reflect this change. No errors were detected.
Merging notes for CO2 merging into S04P:
-Data sent from Alex Kozyr on 2000.02.14. Stripped header info from file.
-S04P bottle file obtained from WHPO website.
-Used mrgsea (DMN) to merge: TCARBN, PCO2, PCO2TMP.
-Missing values in co2 file sent by Kozyr was -999.9. This was changed to WOCE format -9.0 in edited version of data prior to merging.
-Changed expocode in WHPO bottle file from: 90KDIOFFE6/1 to 90KDIOFFE6_1.
-Changed cruise date in WHPO bottle file from: Feb. 14-April 6 to 021492-040692.
-Ran wocecvt, only detected errors were in sumfile.
-Ran read_hyd, no errors.
-Ran maskhyd to add date/name stamp.
-Output file called s04phy_mrg.txt
I just submitted the He, Ne and Tr data from the WHPO lines S4P and P16A/P17A. Please let me know if you can successfully read the data.
Peter Schlosser asked me to start with submitting our helium and tritium data sets that are ready. - I am about to send you the S4P, P16 and P17 data, but want to compare them with John Lupton's data first.
I have changed the three nitrite values for S04P station 716, bottles 4, 5, and 6 to 0.01 per Jim's e-mail. I also reformatted the .sum file. Usual shifting, adding, deleting columns. I did change the EXPOCODE in the .sum file from 90KDIOFFE6/1 to RUKDIOFFE6_1 to conform with what is used on the web site and in the .sea file (I assume this means we are using RU for Russia instead of 90 which was used for the Soviet Union).
My understanding from Bob is that processing of C-13 for these lines is finished. Is it possible to obtain the data and/or an update on their status for the following cruise lines? Any information you can provide would be greatly appreciated! Thank you for your time!
We're finally getting caught up here and we'll be putting out the AMS C14 data for S04P (90KDIOFFE6_1: Feb 1992). NOSAMS date was 9/16/2000, and I'm pretty sure that you've laready OK'd this, but one can't be too sure.
Simple confirmation is all that is required. I hope that all is well on your end. BTW, I'm still working on translating A12 data from you and straightening out the A13/A14 flag weirdness.
I have placed the new bottle data file on the website from the WHOI Pacific Atlas. Mark Warner pointed out to me that he had indeed given the CFCs to Terry Joyce right before the conference. In any case, this file also has TCARBN values and is public.
All tables have been updated to reflect these changes.
-sd 1999.01.14
There is an agreement that Dr. Jim Swift has taken responsibility for preparation of the FINAL CTD/Rossette data (except CFCs) and submitting it to WHP Office for further release. Dr. Mark Warner is responsible for the preparation of the CFCs. I have no objections against data release for public use and greet that these data would be accessible for oceanographic community.
Regards, Mikhail Koshlyakov.
We have now heard back from two DQEs on your IOFFE S4 dataset. Lou Gordon & Joe Jennings examined the nutrients while Eugene Morozov, who is visiting the V;BPO for three months, looked at the salinity, oxygen and CTD data. Each of the reports is attached as well as a table where each of the DQEs have some disagreement with the quality assessment of the bottle data.
First, both of them agree that the data are of high quality, but there are, of course, some problems in their view. As for the CTD data, they were not submitted with any CTDOXY in the bottle data. Some of the early datasets from ODF did not have this, but more recent ones do. You should contact Jim Swift and request that it be added to the file. Besides making the bottle data more complete, it greatly facilitates the DQEs' task of judging how well the CTDOXY is 'calibrated' to the bottles. Note that many of Morozov's comments deal with CTDOXY from the CTD files and how it 'disagrees' with bottle data from the up cast. There are also some suggestions from the data about possible leaking bottles that you might consider. There are only 6 instances where the DQE differs from the quality assessment as submitted by you. Unless there are strong arguments to the contrary, we will accept the DQE suggestions.
There are numerous comments on the nutrient data, particularly the nitrate. Also note that the DQE thought many of your data flagged bad were either questionable or good. In this case, we will let you be the judge-if you want to retain you quality flag of "4", we will do so.
Both reviewers noted that the lack of previous high quality data iu the region, makes it impossible to compare with earlier cruises; this means that your dataset will become our standard for comparison with other W11P cruises in the southern reaches of the Pacific.
I am sending this report to both of you, but I expect Jim Richman to respond to this letter.
We have been waiting for the data evaluator reports on your bottle data from S4, and have only a partial report on the nutrients. We also are still waiting for the CFC data from Mark Warner and the CTD data from Scripps. We will continue to seek these data and will keep you posted when something happens; perhaps a message from you asking for them to be submitted might help? In the meantime, the enclosed floppy disk contains the most up to date version of the bottle data and station summary file we have, as well as a program, written for an IBM-type PC, for looking at the bottle data. It is provided to the data quality evaluators for flagging bad or questionable data; you might find it helpful. Those individuals you listed as needing access to this data set have been contacted by us; you need not send them a copy of the data enclosed.
I am pleased to inform you that the Carbon Dioxide Information Analysis Center (CDIAC) has received the final carbon-related measurements (Total C02 and PC02) from the 1992 R/V Akademik Ioffe expedition 90KDIOFF6/1 (WOCE section S4P). Taro Takahashi, David Chipman, and Stewart Sutherland of Lamont Doherty Earth Observatory provided the carbon-related measurements along with files containing the preliminary hydrographic and chemical measurements and the station inventories. We will furnish you with the results of our DQE on the S4P data after completion. If there are further developments on the DQE and processing of the hydrographic measurements, please let us know.
Mikhail Koshlyakov has requested that the WHP office solicit data, on his behalf, from his S4 cruise on the Prof Ioffe. Our records show the following PIs , and their measurement responsibilities:
Dr. Greg Rau: carbon isotopes
Dr Peter Schlosser: AMS C14, helium, tritium, 018
Dr David Chipman: TC02, pC02 and underway pC02.
Dr Mark Warner: CFCs
If the WHPO can help in any way with the formatting and/or merging of the data into the WOCE format, please don't hesitate to contact us.
Dear Dr. Koshlyakov:
Thank you for sending the WOCE Hydrographic Programme Office the bottle data from your cruise aboard the Ak. loffe for WOCE Line S4. The expocode used to refer to this cruise is 90KDIOFFE6/1.
Dear Dr. Rickman:
Thank you for sending the WOCE Hydrographic Programme Office the bottle data from your cruise aboard the Ak. Ioffe for WOCE Line S4. The expocode used to refer to this cruise is 90KDIOFFE6/1.
Dear Dr. Gordon:
Dr. Joyce asked me to send you the enclosed two diskettes with the bottle data from SR4 (ANT VIII and ANT IX) and S4. Besides the data files, there are *.SUM and *.DOC files for each cruise. We are including reference data from AJAX2 for your use and the latest version of WHPEDIT.
