331969	2009-11-05	Johnson, Mary	CTD/BTL	Submitted	Data Update
30 October 2009 New release of CCHDO A20/A22-2003 Data 1. Replace all the old CTDO data files with the new ones. 2. Bottle Oxygen data were wrong in original bottle file submitted. I would replace ALL ODF parameters, so they jive with our final submission.2003 CLIVAR A20/A22 CTDO and bottle data files were re-generated 2003 CLIVAR A20/A22 CTDO and bottle data files were re-generated Oct. 30, 2009. A review of the data showed problems in the CTD data files produced in Feb. 2004 and in the bottle data files produced shipboard. The problems and their resolution are addressed below, and fixed in this distribution. Temperature data in 2004 were reported as ITS90, when they were actually IPTS68 data. Additionally, a large surface CTD Oxygen problem was discovered and fixed. Apparently there was a program bug when both A20 and A22 CTDO files were generated in Feb. 2004. Surface CTD Oxygen data were off by tens of umol/kg near-surface for both cruises, and well over a hundred umol/kg for many casts. Reported CTD Oxygen data did not return to bottle data ranges until ~400db (A20) or ~30db (A22) in the Feb. 2004 data files. A22 CTD Oxygen data, produced with current ODF CTDO processing software, resemble data values from the ship and agree fairly well with bottle data. However, A20 CTD Oxygen data do not agree well with deep bottle data or shipboard CTD data. CTDO processing algorithms apparently evolved during A22 in such a way that deep CTD Oxygen data produced from shipboard A20 CTD data and corrections files are about 1.5-2% high vs. bottle data. A snapshot of the final shipboard A20 CTD Oxygen data was found in other data listings generated just after corrections were finalized at the end of A20. These CTD Oxygen data agree much more closely with bottle data, and were merged in with the current pressure, temperature, salinity and transmissometer data. (As noted, only temperature values should differ in these other data.) Note that there was NOT a problem with CTD Temperature or Oxygen data reported in the bottle data files. A postgresql database was the source for the shipboard .sea files; it was never updated with CTD Oxygen values while the program was incorrect. However, plots of CTD vs bottle Oxygen data revealed an offset between them in umol/kg units, but good agreement in ml/l units. It was discovered that lab temperatures at analysis time were erroneously stored in the bottle Oxygen draw temperature slot in early versions of the bottle database. The correct data were uploaded into the A20 and A22 databases, and the CTD and bottle Oxygen data now agree in umol/kg space as well. New versions of the .sum, .sea and _hy1.csv files were generated in Oct. 2009 and are also included with this data release. Note that non-ODF data are shipboard status, and probably need to be updated from newer data files submitted by the other PIs. Uncorrected transmissometer data are now included in these 2009 CTD data files. A few surface CTD T/S/O spikes were removed or reduced in this distribution by excluding surface data before the point where sensors had equilibrated (usually before SBE pumps had turned on) from the pressure-series data: A20: stations 1, 15, 37/2, 54, 61, 75, 78, 81, 85 and 87 61/1 CTDO off at surface, ok? by about 20db 75/1 CTDO low at surface, ok by about 10db 85/1 CTDO very low at surface, ok by about 14db. A22: stations 9, 38, 52, 54/2 9/1 CTDS still somewhat noisy, top 10db 38/1 CTDO a bit low at surface, ok by about 16db 52/1 CTDO low at surface, ok by about 22db 54/2 CTDO low at surface, top 2db only NOTE: station 54/2 was overwritten by [deeper] 54/1 at some point before A22 ended. The shallow-cast data were found in and recovered from another file, and reformatted to CCHDO formats. The following extra CTD casts were done because of problems on the primary deep cast (where possible, notes from Console Logs or ODF documentation are included): A20: station 66/1: "deck unit lost power, sea cable conductor shorted, end cast at 750m [up]" station 66/2: "port side winch/wire, pick up top 750+m of water samples from aborted cast 1" A22: station 51/3 (deep cast/5052db): precedes 51/2 in time, "all bottle vents left open, no usable samples taken" [NOTE: documentation says orig. 51/1 was re-named 51/3. CTD trips reported with 51/3 match the original trip data.] station 51/2: (deep cast/4020db): "repeat cast" [NOTE: all bottle data are reported as cast 2] station 57/2 (deep cast/5033db) - precedes 57/1 in time, "broken sea cable conductor/signal loss resulted in premature termination of 57/1 (renamed 57/2) at 4600db after tripping 3 bottles." station 57/1 (deep cast/5035db) - repeat cast [NOTE: all bottle data are reported as cast 1] The following extra CTD casts were for CDOM experiments and have not been processed beyond block-averaging; no bottles were tripped on these casts, and no sample logs were filed. Note that these casts typically preceded the deep CTD casts in time, despite a cast number that was later in sequence. A20: stations 37/2 58/2 A22: stations 14/2 41/2 54/2 The following CTD casts with NO bottle data have been eliminated in this distribution, with reasons explained below: A20: station 89/1 The last station for A20 was 88; this was an on-deck test in port after A20 finished. It should not have been included in any distribution. A22: station 51/1 Renamed 51/3; CTD data in files for 51/1 and 51/3 are identical; however, CTD trips stored with cast 1 do NOT match up with trips logged during cast acquisition (39 vs 36 bottles, different depths). ODF documentation remains the same, since no PTSO corrections were changed. However, the documented "extra" high-order polynomial corrections to CTD Oxygens as a function of Pressure were never applied to the A20/A22 data in CTD files, in 2004 or now. Polynomial coefficients were calculated in ml/l units, but applied to umol/kg values in the CCHDO CTD files, and essentially had no effect on the 2004 CTD data. These data issues were discussed with Dr. James H. Swift, Principal Investigator of the CTD/Hydrographic Support for A20/A22. He agreed that updating the data was appropriate for this data set, and suggested we include documentation that identified the CTD data files with surface oxygen problems.

2009.05.28 DBK Remerging notes for a20_2003a bottle file An error in the merge_exchange_bot.rb code was found after these data were merged. This warrented a remerging of all parameters once the code was fixed. All same intermediate files from the original merge were used in the remerge. All files were copied to directory: REMERGE_2009.05.28. For notes on previous merge (including edits made to all intermediate files) please see merging notes below dated 2009.03.28. No additional problems were detected. All files were checked in JOA. NetCDF files were generated after the parameter table was edited to have BRDU in all caps. Previously, our entry for BRDU was BrdU. Once this edit was made, netCDF files were generated without any problems. Files opened in JOA without problem. A WOCE-formatted file was also generated using excange_to_wocebot.rb code. No errors were reported, however the file cannot be format checked at this time due to the large number of non-WOCE parameters contained in the final file. At this point it is assumed to be in proper format. The first EXPOCODE header was edited to be all caps and WHP-ID was added, as was a date/name stamp. All files were placed online. Previous versions were renamed and placed in original directory. the web update script was run and these notes were emailed to Jerry Kappa.

2009.03.28 DBK Merging Notes for a20_2003a bottle file The following parameters were merged using the new merge_exchange_bot.rb created by Justin Fields. Parameters were merged into exchange bottle file only at this time, the WOCE formatted bottle file is not up to date. ALKALI: These data were sent by Alex Kozyr on 2008.07.28. Header TALK was edited to ALKALI. Data were merged with no problems. TDN, DOC: These data were sent by Alex Kozyr on 2008.02.15. Data were merged with no problems. DELC14, DELC13: Delc14 and error, and delc13 data were sent by Bob Key on 2008.04.17 Header was edited to reflect CCHDO parameter names and units were added to file before merging. Missing values were edited from -9 to -999 before merging. Data were merged with no apparent problems. NOTE:These data were remerged after it was brought to our attention that delc13 had incorrect precision on our parameter table. HE, DELHE3, NEON: DELHE3,HELIUM,NEON and their associated error and flag values were sent by Bill Jenkins on 2007.11.19. Headers names were edited to CCHDO parameter names and units were added. Data were merged with no apparent problems. NOTE: It should be noted that the data history reflects an entry by Bill Jenkins for TRITUM (tritium) data. This entry pertains to the previous occupation of line A20 (1997). There were no TRITUM data submitted for this cruise. There was mention of drawing a sample for analysis in the bottle sampling protocol in the doc file for this cruise, however there is no mention that samples were drawn and analyzed for tritium. BRDU: BrdU data were sent by Craig Carlson on 2006.11. File was edited for use in merge code: line/feed carriage returns were edited into file, header parameters and units were edited to reflect CCHDO parameter names, missing values for data and flags were added to previously blank entries. Flags for valid values were edited from "1" to "2". Several stations had incorrect cast number associated with the station/cast/sample values : edited station 20/2 to 20/1 for samples 7, 5, 3. Stn/cst/samp 37/-9/-9 was deleted as it contained no data values. Five entries of 37/1/-9 were deleted as they all contained no data at all. The duplicate entry for 37/1/6 was deleted as neither entry contained data. After these edits, data merged with no apparent problems. DCNS: This file contained DCNS, FUCO, RHAM, ARABI, GLAA, GLUC, MAN data sent by Craig Carlson on 2006.11.20. File was edited for use in merge code: line feed/carriage returns were added, all parameter and units headers were edited to reflect CCHDO parameters names, missing values and flags were added to previously blank entries, flags for valid values were edited from "0" to "2", however it was assumed that all values possessing a flag "4" were truly accurate and were left as-is. Several stations had incorrect cast number associated with the station/cast/sample values : edited station 20/2 to 20/1 for samples 7, 5, 3. Stn/cst/samp 37/-9/-9 was deleted as it contained no data values. Five entries of 37/1/-9 were deleted as they all contained no data at all. The duplicate entry for 37/1/6 was deleted as neither entry contained data. Entire file was edited after these changes, to contain only data necessary for the merge code to operate. After these edits, data merged with no apparent problems. BACT: BACT, PEUK, SYNN, PROC data sent by Craig Carlson on 2006.11.20. File was edited for use in merge code: line feed/carriage returns were added, all parameter and units headers were edited to reflect CCHDO parameters names, missing values and flags were added to previously blank entries, flags for valid values were edited from "1" to "2", deleted all lines which contained no cast, station, sample numbers which also held no values for bacteria data, deleted all lines which contained duplicate sample numbers and black spaces for values. Edited cast from 2 to 1 for station 20 samples 7,5,3. Stations 63, 64, 65, 51 all contained cast 2 and were changed to cast 1 to match original bottle and summary files. Entire file was edited after these changes, to contain only data necessary for the merge code to operate. After these edits, data merged with no apparent problems. CDOM: CDOM data for 325, 340, 380, 412 nm and spectral slope CDOMSL, CDOMSN were submitted by Norm Nelson on 2005.04.20. The header was edited to reflect CCHDO parameter names. Fewer samples were submitted in the file than contained in the CCHDO bottle file. Missing values were added as such into the bottle file. Values for CDOMSL and CDOMSN at station 37 cast 1 samples 34, 35 were reported as NaN's with flags of "2". In order to merge the rest of the data, these values were changed to -999.0 with a flag of "5" (not reported). An email was sent to Norm Nelson requesting further advice on how to report these two values. Data were merged with no apparent problems. ---------- Final file was loaded into JOA without error and plots of all parameters were made to identify any errors as a result of merging. None were apparent. Final file containing all merged parameters named a20_2003a_mergd_doc_tdn_alk_hene_c1314_bct_cns_bdu_cdom_hy1.csv indicates the order in which parameters were merged. This file was renamed a20_2003a_hy1.csv, citation information prepended to the top of the file, and file was placed back online. NOTE: this file did not convert to netcdf due to unknown errors. At this time, the WOCE formatted bottle file is not up to date with these merged and added parameters. I will attempt to make as complete a file as possible using the new exchange_to_woce conversion code created by Justin Fields and indicate to Jerry Kappa when this has been successfully completed.

This is the corrected and final TALK (Alkalinity) data I received from Andrew Dickson on 07/25/2008 and flags for merging into the master file. Please, let me know when the data will be available online after the merging.
331558	2008-06-23	Kozyr, Alexander	ALKALI	Submitted	Data are final
Here are the final TALK data from Andrew. I will send the metadata file as soon as I get it from Andrew ti include it in the report. Please, merge the TALK numbers ASAP as these data are due so much behind.
331493	2008-04-18	Johnson, Mary	CTD	Update Needed	various errors
Errors found by ODF in CTDO data submitted 2003/2004 for CLIVAR A20/A22: ?CTDTEMP data reported were IPTS68, but labeled as ITS90 ?CTDOXY data did not have corrections applied properly, likely due to a scripting error. The top 10-20db are very skewed for most stations, and deep data are occasionally affected as well. ?Transmissometer data were not included with the CTD data originally, ?Fluorometer data were not block-averaged and are not reported. Corrected CTDO data files were submitted by ODF to CCHDO on 3/18/2008. Uncalibrated transmissometer data are also included, pending updates by Wilf Gardner (TAMU). Fluorometer data were collected with the CTD, but not block-averaged; they are not reported.

331029	2006-11-15	Kozyr, Alexander	CO2	Submitted	Data status summary
Here are the latest update on the Carbon Data status at CCHDO and CDIAC. A20_2003: TCO2 - OK; TALK - no final data from Dickson; DOC - final data were not merged in the exchange file at CCHDO.
330894	2006-11-09	Carlson, Craig	BACT	Submitted	Microbe concentrations/Neutral sugars
Here are several additional ancillary data that accompany the core CDOM data (already submitted) for A20 and A22. They include concentrations of microbes in the upper 250 m, bromodioxyuridine incorporation rates (proxy for microbial production) and concentrations of dissolved combined neutral sugars for A20. I have also included brief standard operating procedures for each parameter. Again these are level III ancillary data to the bigger CDOM data set. These data analyses are extremely labor intensive to generate and were just recently completed, QC'd and finalized. I am not sure how they are to be incorporated into the larger data sets but wanted to make sure data center received these final data.
330989	2006-05-31	Anderson, Sarilee	DOC	Website Updated:	No exchange file yet
May 31, 2006 a20_2003a, 316N200309 Merged the DOC sent by C. Carlson on Oct. 25, 2005 into the online file. There were no apparent problems. The WOCE to EXCHANGE STILL needs to have DOC added, so I DID NOT MAKE A NEW EXCHANGE file.
330977	2006-05-22	Carlson, Craig	Cruise Report	Submitted	DOC report
Here is the documentation for DOC collection and analyses. Let me know if you need any other info

Jenkins is still processing the tritium, and hasn't begun the helium.
330882	2006-02-07	Jenkins, William	HELIUM	Analysis Completed	Data Processing Pending
We have also completed the helium analyses for the A20 and A22 cruises, and I hope to submit those results shortly. I had hoped to complete the data processing prior to the Ocean Sciences meeting, but may have to do it afterward.
330845	2005-10-25	Carlson, Craig	DOC	Submitted	final data w/ Qual flags
The DOC data for A20 and A22 are finally complete. The long delay was largely due to the fact that for a long stretch our machines were down but all the problems have been resolved and all the samples were run when the machines were stable and performing well. Attached are final DOC data and the quality flags for the A20 and A22 lines. For a while we have been trying to submit via the web but have not been able through the submit page so I thought I would forward the files directly to you. Because this page is not working I am not sure if you need any other info associated with this data...so if you need mor info please let me know. The final DOC data in these files are reported as µmol / L. I assigned quality flags according to the WHP codes. There were a few samples from each line that were misplaced or missing so I have entered a 5 as a quality flag for those sample.

The attached matlab-format file holds all the underway data collected on this leg. The two .txt files hold documentation as provided me by the Knorr's science tech. Not all variables listed in the documentation were actually logged. Hopefully the variable names in the mat file are understandable. Please forward to Shawn as appropriate, and let me know if anyone has any questions.

Corrections were made to stations 38 and 40.
330732	2005-03-07	Willey, Debbie	CFCs	Data Update Needed:	will re-submit
Last week, William Smethie sent changes to the A20 (2003) CFC data for stations 38 and 40. Today when I began to make changes to my files, I realized that I needed to do some work to make the appropriate changes to station 38... There are several bottles where both RSMAS and Lamont took samples (i.e., duplicates). These are usually averaged and given a flag of 6, or in the case where one lab's sample is questionable and one is good, the good one is used. This means that rather than flagging all of station 38 CFCs with a quality byte of 3, there are several bottles where the RSMAS data can be used. So, in a nutshell, I will be re-submitting data for station 38 this week, as soon as I make the changes.
330729	2005-03-04	Smethie, William	CFCs	Data Update needed	questionable data points
Since submission of the final CFC data for the repeat of WOCE line A20 (Kn173/1), Sept 22 - Oct 20, 2003, we have found some data points that are questionable and should be flagged as such. All CFC data for station 38 and for bottles 24, 26, 32, 34, 35, 36 of station 40 should be flagged as questionable.
330656	2004-12-17	Kozyr, Alexander	TCARBN	Data Status Check	Data are Final & OnLine
A20 and A22 (2003): I have the final TCO2 data from Marilyn Roberts, I merged these data into WHPO format, made our QA-QC work, and sent the data to CCHDO on June 22, I have automatic confirmation on receiving these data. I've checked CCHDO web site for A20/A22 and noticed that the final TCO2 data were incorporated to the bottle data files. Andrew Dickson is still working on his Total Alkalinity data for A20/A22 sections. I've sent Andrew a message a few days ago with question about a status of his TALK data, but did not have a reply yet. The TALK numbers in CCHDO bottle data file are preliminary and will be adjusted as soon as I get the data from Andrew and work on merging and QC.
330622	2004-11-24	Anderson, Sarilee	CFCs	Website Updated:	WOCE/Exchange/NetCDF files onlie
RCS for a20_2003a Debra Willey submitted final cfc11, cfc12, cfc113, and ccl4 data on Nov. 11, 2004. These final data have been merged into the data file. Sta. 37, cast 1, bottle 12 had a value of 2.000 and a Q flag of 0 for ccl4. Debra checked and sent a new value of 0.429 and a Q flag of 2. Also a problem with sta. 23, cast 1, bottle 36. Cfc12 value is way out of acceptable range and exchange program would not accept, even though the Q flag was 4 (bad measurement). I had to edit the value into both the .hyd and .csv files. Made new exchange and netcdf files and put online.

330553	2004-07-13	Bartolacci, Danie	CTD	Website Updated:	Data Online
Edits made to CTD files for a20_2003a: - Edited all station file header line parameters "No. Headers" to "NO. HEADERS" - Edited date parameter in headers of station files 30, 33, 36, 45, 58, and 66 to match sumfile date. - Ran wctcvt with no errors. - Converted files to both exchange and netcdf with no errors. NOTE- station file 89 cast 1 is an empty file. This is true of original file obtained from data originator as well. Inquiry on this station file will be sent to data originator. At present it will be removed from the ctd zip file and converted format files online.
330542	2004-07-08	Bartolacci, Danie	TCARBN	Website Updated:	Data Online
I have merged the new DIC values sent by Alex Kozyr, into the A20_2003a bottle file. No other edits were made to the bottle file. Data merged with no errors. File was format checked with wocecvt and moved to parent directory. Old file was renamed and moved to original directory. exchange and netcdf files were generated. All opened in JOA with no errors.
330533	2004-06-29	Bartolacci, Danie	BTL	Data file corrected	as per A.Kozyr's email
I have fixed the error found by Alex Kozyr in the A20_2003a bottle file described in the email below. The original data PI's file did not have this error in it and the entire sample/bottle line of data was replaced with the original line. It is unclear at this point what caused the erroneous values in the online woce file. The new file was checked with wocecvt to find no errors and was placed online. original file was renamed and moved to the original directory.

330529	2004-06-21	Kozyr, Alexander	TCARBN	Submitted	Data are Final
I have submitted 2 files to WHPO with the corrected TCO2 values for merging to the master file. I hope you like the format of the files. The quality flags changed a bit too, so please merge the flags as well. However, I have a few questions to the TCO2 PI regrading some quality flags, so they might change in a future. TALK corrected values will be sent to CDIAC in a few weeks by Andrew Dickson per our conversation today.

330523	2004-06-10	Kozyr, Alexander	TCARBN	DQE begun	Received data from Marilyn Roberts
I wanted to let you know that I received the DIC measurements for Repeat Sections A20 and A22 from Marilyn Roberts, PMEL. These measurement were adjusted for CRM measurements and went through preliminary quality control at PMEL. I will have done our routine quality evaluation for these data and will send you new data as soon as I finish.

330452	2004-02-11	Diggs, Stephen C.	CTD/SUM	Data Update:	CTD files Reformatted/SUM file probs preclude making exchange file
I have placed the A20 2003 data online with a webpage. Once we've straightened out the datahist and table generation situation, we will be able to place this page in the online tables for the Atlantic. WEBPAGE: http://whpo.ucsd.edu/data/co2clivar/atlantic/a20/a20_2003a/index.htm WOCE Formatted Files: CTD files were format corrected to include the new WHPO generated expocode as was the sumfile. the bottle file had incorrect NO_DATA values and was reformatted as well. The new expocode was included in the bottle file for consistency. WHP-Exchange files: The Sumfile from ODF has minor formatting issues which preclude the translation of the bottle and CTD data into WHP-Exchange. I will attend to these problems when I return on Tuesday, 2/17/04.
330453	2004-02-11	Diggs, Stephen C.	Cruise ID	Expocode Changed	now 316N200309 (was 316N173/1)
The A20 data is formally online at a new location: http://whpo.ucsd.edu/data/co2clivar/atlantic/a20/a20_2003a/index.htm You'll notice that the expocode for the WHPO website is now 316N200309 (was 316N173/1). This is consistent with the way the WHPO/CCHDO now keeps records and assigns expedition codes. Each cruise has an NODC shipcode, then the 4-digit year and the 2-digit month taken from the first date of the cruise. We realize that this may cause problems for individuals who refer to A20 by the old expocode.
