Notes on A09 CTD file corrections Jan 27, 2011. Expocode 06MT15_3 D.Muus Bob Key reported problems with the Exchange and NetCDF CTD files Found an extra line in the Station 223 WOCE format CTD file that interfered with the Exchange to NetCDF conversion. Last 3 lines in file M15S223.WCT: 3024.0 2.5686 34.8928 225.9 1 2223 3026.0 2.5686 34.8924 226.0 1 2223 ^Z Removed the "^Z" line and remade Exchange and NetCDF file from the on- line WOCE format files. The new Exchange and NetCDF CTD files were checked with Java OceanAtlas and put on-line along with the corrected WOCE format CTD file.
New PDF and text docs online.
Merged ALKALI into online file re Kozyr's email. Put merged file online, made new exchange file, sent notes to Jerry. May 20, 2003 a09 06MT15_3 Alex Kozyr noted that there was no ALKALI in the online file and requested that it be merged. I retrieved the data from his web site and merged the ALKALI into the online file 20010321WHPOSIOSTAFF. I copied the Q1 flag into the Q2 flag field. Sarilee Anderson
*See PC02 entry.
The TCARBN and PC02 was merged by SE. The data was retrieved from the CDIAC web site re Kozyr's e-mail (Aug. 14, 2002). Made new exchange file. Notes for the a09 merging: After merging tcarbn, did a diff on the collums tcarbn and Q1, and they were exactly the same. So didnt do the tcarbn merging. The data in a09_carbon.dat for PCO2 had missing data flags of "-999.9". I changed these to "-9.0", because this is what they should be. Added a q2 flag to a09_carbon.dat so it exactly matched q1. Then merged the param PCO2 and the missing data values are correct, and the q2 flag is the same as the q1 flag. Hand edited the final file headers so the last collum all lined up.
Exchange code was re-run and missing C14 parameters in the files are now included.
CTD has been converted to exchange using the new code and put online.
*check.txt created for this cruise. sal and oxy .ps files created for this cruise.
The exchange bottle file name in directory and index file was modified to lower case. CTD exchange files were put online.
Bottle file in exchange format has been linked to website.

I have replaced the current online sumfile with the newly reformatted file and moved the old file to the "original" subdirectory. Reformatting completed by S. Anderson. Tables and referenced have been updated to reflect this change.
Updated values from Birgit Klein merged into on-line bottle file by David Newton. Placed online after checking, associated files and tables updated.
had to resolve questionable sequential cast numbers in new file again. Stn139 cast 1 btlnbr 201 could not be merged. but moot because values were missing. Stn196 cast 1 btlnbr 213 is probably a stray. changed it to btlnbr 224. Deleted stn196 cast 1 btlnbr 224 as it contain bogus missing cfcs. Corrected bogus missing cfc11s of -8.7796 and bogus missing cfc12s of -9.1148 The CFCs used none of the nonstandard quality flags noted by the originator.
We report final freon, helium isotope, neon and tritium data for the WOCE-WHP A9 (South-Atlantic) section (zonal at about 19 South) METEOR -cruise 15/3 (zonal at about 19 South). The data are stored under the file name 'wocea9.dat'. The bottle data file stored below contains all hydrographic variables although we contribute only tracer data. Freon data and helium data have been submitted earlier but should be replaced by the final values. The new and final data which should be included into the water sample file are: CFC11 (column 12) CFC12 (column 13) HELIUM (column 22) DELHE3 (column 24) TRITIUM (column 20) NEON (column 26) and their respective errors CFC11ER (column 12) CFC12ER (column 13) HELIER (column 22) DELHER (column 24) TRITER (column 20) NEONER (column 27).

Storage time is indicated in the data file and amounted between 2 to 3 years. An internal standard filled with regular air has been used for the helium isotope and neon measurements at the laboratory in Bremen to make all measurements internally self-consistent. An external standard does not exist. The helium data reported now have been corrected for tritium decay, this correction is in the order of at maximum 0.6% and effects only the upper waters. Tritium measurements Tritium samples are stored in 1 liter glas bottles and were extracted later on in the laboratory. Tritium concentrations are measured by helium-ingrowth, therefore the same standard procedures apply as for helium. Tritium concentrations have been decay corrected to March 1st 1991. CFC measurements: CFC measurements were continously performed during the cruise by gas chromatography. The CFC data reported earlier were based on the SIO86 scale and have now been rescaled to SIO93 using the following corrections: F11_SIO93=F11_SIO86/1.0251 F12_SIO93=F12_SIO86/0.9874
Again, I would like to declare all CTD and all bottle data including the tracer-data of the WHP one-time cruises A9/M15-3, A10/M22-5 and A8/M28-1 as public. This has been done several times earlier, and I hope that by now this information will flow into your files. Also please note, all CTD-data from repeat hydrography cruises / mooring cruises with chief scientists / PIs T.J. Mueller, W. Zenk, and/or O. Boebel/C. Schmid are public. Viel Glueck Thomas J. Muller (speaking also for G. Siedler/M15-3; R. Onken/M22-5 and W. Roether/Tracers)
Re: Meteor 15 (WHPO # A09 : 06MT15_3) I have run into some issues with the 1997 CFC file that you sent to the WHPO. In that file, some of the CFC values are -8.7796 and -9.1148. While these are clearly out of the range of valid values for CFCs, I think that perhaps your software was writing out numbers approximating -9.0, the NO_DATA values for WOCE. I had also received an updated C14 file from Matthias Arnold (Institut fuer Umweltphysik der Universitaet Heidelberg) on 1998.08.10. In that file he has CFC values, I'm assuming that they are from you. This file has no large negative values except for the usual -9.0 as NO_DATA values. In addtion, some of these CFC values for the same CAST, STN and SAMPLE differ from your values in the 1997 file. Did you update the CFC values from A09 after 1997? The question is, which file do I use to merge the CFCs into our bottle file online? I will send you a uuencoded compressed tarfile of these files and you may judge for yourself. Just be aware that the pressures are inverted from one file to another, and the BTLNBRs in one file match the SAMPNOs in the other. The tarfile will be in a separate message.
I have placed the updated version of the hydro bottle file online which has the new (1999/12) version of He/Tr/Ne. All tables and files have been updated and the files are now archived.
Notes on modifications made to A09 expocode 06MT15/3 From file a09_1999.12.09.bklein.he-tr.txt merged in HELIUM HELIER NEON NEONER DELHE3 DELHER and added TRITUM, TRITER File named above had unusual sequential cast numbers that were reconciled to correct numbers before merging. In file named above station 139 cast 1 botlnbr 201 is probably really station 139 cast 2 botlnbr 201, but it's moot because all values are missing anyway. In file named above station 196 cast 1 btlnbr 213 is probably a stray, but it's moot because values are missing anyway. In file named above two DELHE3 values had -9 as value, but had a 2 recorder in Qflag. These were stn 157 cast 1 botlnbr 203 and stn 214 cast 2 botnbr 320. Left asis Scores of DELHE3 values were -9.00 with Qflag of 4. Left asis. In file named above all DELHE3 missing values were -9.00 instead of -999. I fixed this in merged file. Rearranged columns into WHPO 90-1 table 4.1 order. 25Feb2000 David Newton
I've just put a total of 13 ﬁles [carbon data measured in Indian (6 files) and Atlantic (7 files) oceans] to the WHPO ftp area. Please let me know if you get data okay.
I received the below msg of Robert Key while I'm working in Brazil for a week. It concerns with a problem that arose earlier with A9, and may arise with A8, too. The problem maybe identified as Robert Key suspected: On all 3 sections A9, A10 and A8, the Kiel CTD group on-board counted casts increasingly, starting with 1 and ending with some high number. All other groups on-board were asked to keep these cast numbers for identification. To my knowledge, and J. Holfort may confirm this, the cast numbers as created on-board have been used in the CTD and SUM files we sent to the WHPO. Later (I do not exactly remember when) I got to know that someone at the WHPO changed the cast numbers in the SUM and CTD files to start with 1 for each station (as it is usual for the rest of the world). However, changing the cast numbers in the CTD and SUM files will cause problems with the rosette file as it will be completed with additional data flowing in. It seems to me that this is the problem the WHPO now is facing. The way out of it would be as recommended by Robert Key: DO NOT CHANGE CAST NUMBERS BUT KEEP THEM KEEP THEM AS THEY ARE SENT IN BY THE PIs (besides obvious mistakes). To solve the problem, you may have to reconstruct the original cast numbers from the original SUM and CTD files as they were sent in by the PIs. Juergen Holfort who has sent the CTD, SUM and part of the HYD files for A8, A9 and A10, and myself will assist if neccessary. Regards Thomas J. Mueller
as I understood from the mailing with Jerry Kappa you are unable to locate the tritium and final helium data for a9. I think they have been submitted to WHOI but it is no problem to submit these data again. The data file is called a09trihe.woc and the accompanying meta information is given in file m15tridoc.txt. The delhe3 data are tritium corrected and are therefore final, helium and neon data did not need a correction. All quality flags follow woce standards. All data including the CFCs which are not submitted again can be public.
The helium data I submitted for a9 have the following meaning: Helium stands for the isotope helium4 delHe3 stands for delta-He3 and is the deviation of the isotope ratio of helium3/helium4 compared to helium3/helium4 ratio in air (given in percent). Neon stands for the isotope neon20 Helier is the individual error assigned to the respective helium measurement. delher is the individual error assigned to the respective delta-He3 value Neoner is the individual error assigned to the respective neon value I submitted today helium measurements for WHP section a8, the file was named WHPA8_he.dat, the corresponding documentation is given in whpa8_he.txt. The helium and neon isotope measurements for this cruise have just been finished and have not been reported yet. The delta-He3 values for this section are not final yet because we need to make a correction for tritium decay during storage time but these corrections are small.
