Those data had not been through the normal WOCE QC procedure, so I assigned flag values for the "routine hydrographic parameters" as well as the CFC data. Toste Tanhua who participated in the cruise double checked/edited the flags I set for CFC. I requested and received TCO2 and pCO2 data from Jon Olafsson, merged these data and QC'ed the values.

In addition to the H3/He3/H4 data from Bayer: I have QC'ed this entire cruise. This morning I received QC flag confirmation/edits for the CFC data from Toste Tonhua who worked with Elisabet Fogelqvist on these measurements. The CFC data are noisier than usual because alternate samples were analyzed on 2 different GC streams and the two instruments weren't sufficiently intercalibrated. After months of digging, I have received printed lab reports from Jorun Gislefoss who worked with R. Nydal on C14/C13 samples. I believe these reports contain some results from this cruises which I will have to manually enter. These data have been particularly difficult because of Nydal's death and the fact that Giselfoss is no longer in oceanography. I have not been able to contact F. Rey, who was in charge of the nutrient measurements for this cruise. Fortunately, the nuts/o2 for this cruise aren't bad. This is the same cruise that J. Olafsson recently sent to various places (9/15/06) because he had added the TCO2 and pCO2 data. I immediately followed his submission with a recommendation that the receipiants of that file "do nothing" until I had QC'ed these data. I completed my QC of the carbon data and submitted these back to Olafsson for vetting and requesting additional details which are required for pCO2 data. I now have his reply. There are 2 minor problems with the file currently on line (http://whpo.ucsd.edu/data/repeat/atlantic/ar18/ar18_d/ar18_dhy.txt). The ones that gave my software fits are the 2 names "CFC-113" and "CCL-4" which should be "CFC113" and "CCL4" (ok,ok, my code is archaic). Bottom line: I will complete my work on this cruise soon and will immediately submit to you since this is an official WOCE cruise. Everything will have been through primary QC and there will be several additions. Jim, Dave or some other high latitude expert may want to double check the salt flags I have applied, but otherwise the new version can simply replace intoto what you now have.
Dear Bob, as you will not know our activities in the ocean where terminated several years ago and all the people involved in tracer data production are gone (except me, but my new tasks in the institute are some sort away from science). Before this happend and the files were closed all our relevant data was reported to WHPO. Fortunately you are not the first who asked for 58JH0894 data set during the last years. Amongst others I sent the data to WHPO at least twice (wondering what they are doing...anyway), thus I was able to recover the data set on short notice (see enclosed). I have no longer any record how many samples were sampled (143 as you wrote sounds reasonable) but totally 114 tritium/He3 and He4 data were derived from this cruise. A part of the samples was lost, another part discarded, and all corrupted data was erased from the final report. This is the reason to state that all our reported tracer data is "good" (this with respect to quality flags which are not included in the appendant file and are not accessible to me any longer). Please feel free to use this data however you like. There are no related publications to cite, referring to the Institute of Environmental Physics, University of Heidelberg and me as PI ist sufficient.

I have assessed the TCO2 and pCO2th data from the 1994 R/V Johan Hjort Nordic WOCE cruise and entered it into the data file from the whpo website (http://whpo.ucsd.edu/data/repeat/atlantic/ar18/ar18_d/index.htm). The product is attached. This data is now submitted to the CARBOOCEAN “Carina collection” and to WHPO.
I have unencrypted the bottle and ctd files for the cruise 58JH0894_1 (ar18_d) and have updated the website to indicate that they are no longer encrypted. I have also responded to Dr. Blindheim that this problem has been solved.
Dr. Robert Key (key@Princeton.EDU) recently contacted me regarding data from the WOCE AR18 line, telling me that these data from 1994 are still encrypted. This must depend on some regrettable misunderstanding, and I ask you to make the data public.
New file is missing CCL4 that previous BOT had and CFC flags. New HE/TR file sent by Bayer needs merging or is possibly already in Blindheims new BOT. Need to email Blindheim to straighten out problems and for PUB status (currently all NONPUB). Email Blindheim for file clarification and PUB status. Rfmt files and create exchg.
TXT and PDF documentation have been put online.
CTD has been converted to exchange using the new code and put online. According to data history this data is still non-public so exchange zip was encrypted as well.
It sounds like it would be better for us to have the measurements you took rather than the poorer quality values contained within the C14 data file we received. May we obtain the DIC values from you at this time?
I have looked at the DIC data and it is clear that they are not from our work in Nordic WOCE 1992 and 1994. The data you sent me seems to be from the work of Dr Reidar Nydal who participated in the cruises. His team carried out DIC by vaccuum extraction onboard. I have seen his results from the 1992 cruise in a technical report dated 1995 where the results were 0.010 mmol/kg higher than in your message. I have some DIC data from the two 1994 stations you list made by coulometric measuremenmts, quality controlled with Dickson CRMs. The agreement with the data you have is poor, differences are both +ve and -ve and amount to several 0.010 mmol/kg.
Tritium, delhe3 and hel4 and error values from Bayer have been placed in the original directory for 58JH0894_1 in the subdirectory 1999.10.01_AR18_TR_DELHE3_BAYER These data are not in WOCE format and need merging into the bottle file data are public as per Bayer.
I was on these two cruises and have data on pCO2 and TIC from them. I did not measure pH or C14. If Johann has sent you data from me then it is from from my submission to him a good while ago. In that case a correction is required. I suggest that you send the files (SEA and SUM) you have received from Johann Blindheim. I can then inspect the pCO2 and TIC data and inform you if and which corrections are required.
I have attached the c14/13 files sent by Dr. Blindheim. If you could please advise us on the quality of the TIC (DIC in file) and PCO2, it would be greatly appreciated.
I am wondering, whether the latter submission ever was acknowledged and the data was further processed by WHPO. In case of the cruises with Johan Hjort you mentioned in your email request, there were in deed several inquiries by WHPO staff maybe in 1999 or 2000. As our activities in oceanography were shut down with the end of WOCE in 1999 I cannot further do any work on this data sets. If re-submission of our WOCE tracer data as specified in the ftp.log file is desired please supply detailed instructions how to do this, by then I may relocate the files from 1998 and may send them just as they are. 98.08.03 13:38 B C:\DATA\WHP-FILES\06MT14-2.SEA --> whpo.ucsd.edu /INCOMING 06MT14-2.SEA 98.08.03 13:38 B C:\DATA\WHP-FILES\06MT18-1.SEA --> whpo.ucsd.edu /INCOMING 06MT18-1.SEA 98.08.03 13:38 B C:\DATA\WHP-FILES\06MT22-2.SEA --> whpo.ucsd.edu /INCOMING 06MT22-2.SEA 98.08.03 13:39 B C:\DATA\WHP-FILES\06MT27.SEA --> whpo.ucsd.edu /INCOMING 06MT27.SEA 98.08.03 13:39 B C:\DATA\WHP-FILES\06MT30-2.SEA --> whpo.ucsd.edu /INCOMING 06MT30-2.SEA 98.08.03 13:39 B C:\DATA\WHP-FILES\06MT30-3.sea --> whpo.ucsd.edu /INCOMING 06MT30-3.sea 98.08.10 14:24 B C:\DATA\WHP-FILES\06MT15-3.SEA --> whpo.ucsd.edu /INCOMING 06MT15-3.SEA 98.08.13 14:04 B C:\DATA\WHP-FILES\06MT22-5.SEA --> whpo.ucsd.edu /INCOMING 06MT22-5.SEA 98.08.14 12:12 B C:\DATA\WHP-FILES\58jh792-1.sea --> whpo.ucsd.edu /INCOMING 58jh792-1.sea 98.08.14 13:43 B C:\DATA\WHP-FILES\06BE73-1.TRH --> whpo.ucsd.edu /INCOMING 06BE73-1.TRH 98.08.18 13:13 B C:\DATA\WHP-FILES\06MT3023.LVS --> whpo.ucsd.edu /INCOMING 06MT3023.LVS
I return to your e-mail of 31 March 01 and my promise of returning to the helium/tritium data. I have now contacted Dr Reinhold Bayer at University Heidelberg and understand that he has already sent the Helium/tritium data to you. He also writes that last week he was contacted by you when you acknowledged the receipt of his data from AR18 for the 1992 and 1994 cruises. My message is that the helium tritium data you received from me via James Crease are unknown to me. I can not identify them and I can not imagine how they have come into that file. You should use the data you received from Dr Bayer and erase the whole file from 1994 which you received via James Crease. All dat from AR18 may be made public. Sincerely Johan Blindheim
58JH0894. Please do not use the file I sent to James Crease. I have now clearified that this was a file where we applied a correction procedure recommended by Seabird, which they later admitted were not as good as the final one we used. So, keep the file you have received from WHPO. As to the Helium/tritium data, I must admit I was a bit surpriced to see them in the file. What I remember is that the people at Heidelberg wanted to submitt them directly. Anyhow I must have received them somehow, but as I was not by that time aware that I should be asked about this all these years later, I did not write a a complete log of everything. Therefore I do not dare say now that the helium/tritium data in the SEA file I sent to Jim Crease are good. I shall send my file to heidelberg to get them checked and then let you know. I attach the C14 data from the two profiles we collected in 1994. I have finally received them myself. For CO2 data from 1994, the status is as for 1992. Finally, use the files you received from WHPO, not those from Jim Crease. Sincerely, Johan Blindheim
Jim Crease forwarded on to us new data files for 58JH1092, and 58JH0894, as well as the emails containing the status of outstanding data and their contacts. I'd like to clarify what we received with you just to make sure we now have everything that is available. 58JH0894: The new bottle file sent by Jim has helium and tritium data in addition to the parameters we currently have. Our current online file contains CCL4, which the new file does not. CFC values at first glance appear to agree with values in our current bottle file, however the new file has no quality flags for the CFC values. Also, CTD salinity values differ between files. As I understand from your letter to Jim, there were only two stations of C14, and they are being looked into. Can you please instruct us as to how to handle this new bottle file? We can use the new file as an entire replacement to our current bottle file and merge in the old CCL4, but it is unclear what to do with the new CFC values which do not have flags. Can you please advise? And finally, can these new data be made public?
The WHP office has received helium and tritium data for two repeat WOCE cruises: WOCE line AR18, expocodes 58JH1092_1 (during July of 1992) and 58JH0894_1 (during July-August of 1994). Our documentation lists you as the PI for the data for both cruises. At present we have no information on the public status of these data and are hoping you can help. May we release these data to the public at this time?
Data files are Excel spreadsheets and will need to be converted to WOCE format. Bottle file has ctdpress, ctdsalt, theta, bottle salts/oxy, nutrients, cfc11/12/113 as well as helium/tritium. Columns for C14/13 are blank. No CCL-4 was included. Quality bytes for all but CFC's are present, but they are contained in columns directly following the parameter column.It is not expressly stated whether these files may be made public, and Blindheim will be contacted for public status as well as confirmation that these files are to replace the current online files. Current online bottle file has ctdpress, ctdsalt, theta, bottle salts/oxy, nutrients, cfc11/12/113, CCL-4. Has Q1 and Q2 words.
Expocodes for sum 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.
2000.12.11 KJU 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.
The He/tr and C-14 data are still with the PIs. I have been in contact with Prof Nydal (now retired) about the C-14 data and he promised to mail them to you. It is only two profiles. I hope that Dr. Bayer at the University of Heidelberg also will be able to provide the He/Tr data.
As I indicated last week the situation here has not changed and the data available will not be modified any more. Again attached, I send s set of 114 tritium/helium data from the AR18 repeat cruise in 1994 and the summary file for all the WOCE cruises where we did tracer sampling. This week Johan Blindheim showed me a data file from the 1994 Johan Hjort cruise which included a much higher number of helium/tritium data we ever measured. Also, the few data points I checked were pure nonsense. Please use the data I attach here once more! I just mentioned no quality flags are included for the single data points. The reason is that the few questionable data points were erased (and are not available any more) before this file was edited. So - the quality of all our data listed is "good". This is what I finally can do with respect to the 1994 AR18 cruise.
By email from September 29 you requested information about tracer data collected during the AR18 cruise of Johan Hjort in 1994. In deed a member of the department of tracer oceanography of our institute (which does not exist any longer) took part in this cruise and collected only a few samples for analyses of tritium and helium isotopes. The sampling was focused on the characterization of overflow water masses and does not meet the sampling scheme usual for WOCE cruises. So only 114 sets of tritium/helium data are available, which were not reported to the WHPO so far. You will find this data attached to this message and I hope you can use it as it is. The error of each measurement is indicated. The people who analyzed the samples and evaluated the data did not specify any quality flags, but usually the quality of our tracer data is (very) good. The name of the attached data file is 58JH894.txt, columns are specified in the header and separated by TabStops. 3He is reported in the delta notation which gives the per cent deviation of the samples 3He/4He ratio from that of atmospheric air (which is 1.384E-6). By the way, I also add a summary file (SUM-WHPO.txt) of all the WOCE tracer data processed in Heidelberg. As you will see, most of this data has been reported to the WHPO (via INTERNET) in 1998. We never received an acknowledgement for the submission, and I have the feeling something may have failed. Maybe you can check this? Please come back to me if resubmission is required or if further questions arise. All our data submitted is free and may be used by the scientific community working with WOCE data.
