Files in the Dataset are the data for this cruise. They are updated when new data are submitted or as needed.Download Entire Dataset Submit Data For This Cruise
I downloaded this file last on 8/23/02, but I believe the problem still exits with your current Exchange file (didn't look at WOCE format). All of the NO3+NO2 flags were/are set to 9. I reset flags to 2 where values existed then ran through my QC software. The data are very nice, but in my opinion, 4 values should be flagged 3: 10-2-320 36-1-201 51-2-319 71-1-304 I don't know whether it is less work for you to fix the flags in your version or replace all the NO3+NO2 flags. If the latter, let me know and I can send a file with the corrected flag values.

Made new exchange file re A. Kozyr's e-mail. April 17, 2003 Notes for a10: WHP line a10, EXPOCODE 06MT22_5 Made new exchange file re Alex Kozyr's e-mail. Had to make a temporary change in the .sum file in order to make it work. Changed the BIO designation to ROS (the Data History indicates that this was also done to get the CTD exchange files to work). Alkalinities are there now. Sarilee Anderson
The WOCE bottle file header for delO18 has been edited from O16/O16 to O18/O16. Exchange, netCDF and inventory files were recreated by KJU. this error was present in the original WOCE bottle file.
Original CTD had a mislabeled element in the header that was causing code to break. Problem was fixed and new files were created.
Used mrgsea to merge all files. C14: DELC14 column had -9.0 for missing data (corresponding flags were 9). Because delc14 can range to -300, these missing values were edited to -999.0 in the merged file. 11 duplicate station/cast combinations were not merged.
CO2: Both TCARBN and ALKALI columns had -999.0 as missing values. These missing values were merged into new bottle file. It appears that only ALKALI data was new (TCARBN values appeared to be identical to those already in file) however both parameters were merged. 1816 samples were not merged into existing bottle file. These samples were associated with station/cast combinations that were not present in the WOCE bottle file and are listed in the file unusedCO2.txt. It is unclear at this time if the sample numbers were misslabled or simply extra samples not included in the original WOCE bottle file.
TR: Both TRITIUM and TRITER columns had flags associated with them. Both flags were merged. 11 duplicate station/cast combinations were not merged.
CTD files had mismatching dates and cast values. The CTD dates indicated only one year 1991 when sumfile indicated the cruise took place 1992-1993, it was therefor determined that the CTD's had wrong dates and the error was corrected. Station numbers 622 - 632 were taken at the end of 1992 and Stations 1-100 in 1993. Cast values in the CTD's were made to match the sumfile. For a complete list of these please see the README in the original directory. CTD were converted to exchange and put online. NetCDF files were made accordingly.
CTD station files have sequentially increasing cast numbers over all stations, that do not match those cast numbers contained in the summary file. No CTD exchange files have been generated at this time due to this problem.
CTD could not be converted to exchange because of a cast number mismatch with the sumfile. The cast number values in the CTD files are sequentially increasing and do not match the sumfile. The CTD zip was replaced with a modified one that has an additional Number of Observations column with -9 values and an underscore in DEG_C.
Bottle has been converted to exchange and put online. Cast types BIO in the sumfile were changed to ROS for the purpose of the conversion. Data was checked with JOA with not apparent errors.
Expocodes for bottle and sum were 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.
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 sumfiles.
Water sample salinity observations were found for only approximately 1/3 of the total water sample observations. The following edit criteria comparing CTD and water sample salinity found the following 15 questionable CTD or water sample salinity, both flagged "3". Notice that the deep water edit criteria (0.01) was not sensitive enough to identify questionable salinities of station 29. |ds| > 0.2 psu for pressure <=500 decibars; |ds| > 0.02 psu for pressure >500 and <= 1500 decibars; |ds| > 0.01 psu for pressure > 1500 decibars;

Many thanks for merging the tracer data into the a10 file. You have done a very thorough job. Thanks for pointing out that erroneous tritium data value on line 3404. You are right the value is wrong and should be replaced by -9.000. It is always good if somebody independent looks at the data and is able to find errors. You are also right about the duplicate lines, I noted that while I was merging the data, I have no clue what is the meaning behind this.
The following information should be filed for A10. I have edited the erroneous tritium value in the file and changed th e date/name stamp. Also left all duplicate lines in the file as per Birgit's email. DBK
Mueller SPECIFICALLY says that he is the ChiSci and we've *never* heard from Onken. Not once. Mueller is ChiSci. I'm also sending this note on to Bert. Unless he had compelling information to the contrary, Mueller stays ChiSci and you need to update the 'ol database.
I'm done merging all the new tracer data into our current bottle file, and it is up on our website, replacing the old masked bottle file. Just to confirm: I found 11 duplicate station/cast/bottle number combinations. The duplicates didn't have any new data in them to be merged, but they were left in the current bottle file. Also, please take a look on line 3404 in the tritium column of our bottle file. This value seems erroneous, but I'm not too familiar with tritium. It was from the current version of tracer data you sent us. Please let me know if this value needs correcting. The following were merged into A10. The notes on merging are contained in the file called 00_README which is in the A10 "original" directory. Thanks-danie CFC-11/12, CCL4, TRITUM, TRITER, DELHE3, DELHER
As per Birgit Klein, I have edited the erroneous tritium value on line 3404 and changed it from -8.753 to -9.000, and left the duplicate lines in the file as well.
The easiest solution at this point is to merge ALL the values you stated below into our current bottle file. If this is satisfactory to you, I will go ahead and do so. I will also edit out the CFC-113 column.
I finally checked the encrypted a10 data set you send me against the tracer data sets we have submitted. As you correctly noted the CFC11 and CFC12 data in the file are not identical with the final tracer data version I submitted in 1999, although I had indicated that these two species should not have been different from the data I submitted in 1997. The data in the file are definitely not the CFC data I have submitted in 1997, it seems to me that the 1997 file has never been merged at all, and that the data you have in the file are most probably the oldest version possible, most likely a ship version with none of the later checks and calibrations applied. It is rather disturbing that such old versions of data are made available at the web site and none of later updates has been included. I would advise you to merge all the CFC data again from the final file I send you. Please remember that CFC113 is set to dummy data for all measurements because the analysis was not successful. If you want to delete the column from the bottle data file it is fine with us. You also have to merge the tritium data and the tritium-corrected delhe3 data. Helium and neon in your file are identical (within the number of digits) with the final file.
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)
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
The problem is a cast inconsistency between the WHPO files and those created by Alex for NDP-066. Additionally, there is disagreement between the WHPO sum and hyd files with respect to cast numbering.
I am submitting today the whole tracer data set for a10 again. The tritium data are submitted for the first time, helium and neon data are the same as submitted 9/97 but the delhe3 data are slightly different due to the tritium correction applied. The helium, delhe and neon quality flags of the data set submitted in 9/97 did not follow strictly the woce standard, I have corrected this in the present version. I am also submitting the CFC data again to give you a complete tracer data set. The CFC data have also been submitted before in 9/97 and CFC-11 and CFC-12 remain unchanged. The only change is for CCl4 whichgot a lower efficiency correction now compared to the data set submitted in 9/97. All data (including the tritium data submitted now) can be public.
the quality flag for N03+N02 on line A10 is always 9 even when there is a value there. Again we will have to contact the PI for corrected information.
CTD, oxygen and nutrients are accessable at the WHPO; they are public although not yet evaluated by the WHPO. - T.J. Mueller
File was received 1998.07.08. Data appears to be the original CO2 data. Could not determine who sent the data. Path is atlantic/a10/original/1998.07.08_C02_A10.
In your a10_sea.txt file I found some quality flags problems for CFC-11 and CFC-12 (station # 14). There are some flags "4" along with missing data.
I was given notice that the previously submitted bottle file of WOCE section A10 had an error (additional copies of some data cycles). I transfered a corrected bottle file to 184.108.40.206.
06MT22/5 A10 Onken/Mueller/Putzka One section: A10 (stations 1-100) plus test stations 622-632 at start Data status: proprietary -------------------------- sum: no errors detected -------------------------- sea: depths out of sequencing and pressure inversions on 89 stations. Many duplicate depths. Run seaorder before gridding Major problem with quality flags in the hy2 file. The block of flags from NITRAT to TRITUM is shifted to the right by one, and NITRAT is flagged 9 throughout although there is data. I suspect that there shouldn't be a flag for TRITER (to be consistent with the other ER columns), and that someone has forced an extra quality flag to match the number of **** columns. Temporary fix in order to grid NITRAT, CFC-11, CFC-12, CFC113, CCL4 and TRITUM: add a ******* under THETA and delete a ******* under PH After doing this, found no CFC113 or TRITUM points to grid. -------------------------- ctd: no errors detected
You may qualify the CTD, oxygen and nutrient data of A10 as 'preliminary' and 'public'. For the tracers including Helium, Neon, etc., ask Wolfgang Roether; for CO2 plse ask Doug Wallace.
I submitted also today CFC, helium and neon isotope measurements for section a10 again. The file was named WHPA10.dat and the corresponding documentation is given in whpa10tr.txt. We have noticed that the CFC measurements for this cruise were calibrated against the wrong SIO scale and the data submitted today have been corrected for this error. I did submit helium and neon measurements as well because I was not certain you had recieved those. The are identical to the data submitted earlier.
