1993 Marion Dufresne Cruise
Key: Samples collected, but not reported due to problem with clamps, etc. (atmospheric equilibration/contamination). 
Jean-Baptiste: Helium isotopes were not analysed due to clamps problems. Tritium was analysed but raw data need check before release

Hi Mark- Sarilee and I have been working on remerging all of the CFC values in the list below.  I don't think she's run into any problems, but I need to run some questions by you before I finish. 

I06- Has flag issues:  stn 25, cst 1, btl 12  has a valid value for CFC-11 but the flags are "0" for both QUALT1 and QUALT2.  This is not a valid flag value.  This is also true for stn 25, cst1 btl 7 for CFC-12.  Admitedly, these flags are also "0" in our online bottle file, but now would be the time to correct this.  Can  you advise us on what the Q2 flag should be for these values?

Also in both the resubmitted CFC file and our online file, many stations exist where the flags are "9"(sample not drawn) even though values are present.  Can you advise us on the Q2 flags for the updated file, so that we might correct them during the merge?

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.

Notes on replacing truncated I06SA CTD files. 040206/dm

1. Replaced CTD data on truncated files i06sa0006.wct, 0010, 0013.3, 0014.2, 0018, 0021, 0032, 0040, 0045, 0047, 0047.2, 0048, 0049 and 0052. using data from Sarilee Anderson's backup tape from when she did the same work in October 1998. 

2. Changes regarding renaming the 1993 i06s line to i06sa to differentiate it from the 1996 i06sb line were also made.

3. New exchange file was checked with Java Ocean Atlas and new netCDF file made. NetCTF check with JOA showed missing QUALT1 word on Station 18 Cast 1 deepest level (5343db). This was not obvious on exchange file JOA check. Since P, T, S & O2 values looked good I added "2222" QUALT1 to this level.

4. Missing bottom depth on Station 42 Cast 3 required the usual work-around to convert WOCE format to Exchange format.

As noted by Bob Key and Alex Kozyr, station 25, cast 1 had the THETA and SALNTY values reversed. I corrected this and put corrected file online and made new exchange file.

Merged the TCARBN and ALKALI for i06sa (35MFCIVA_1) retrieved from the CDIAC web site re Kozyr's e-mail. Made new exchange file. Sent notes to Jerry.

Notes on I06Sa changes.     July 24, 2002    D. Muus

1.  SUMMARY file from web  (20011024SIOWHPODMB)    
* Changed WOCE SECT from I06 to I06SA
* No sumfile entries for Cast 2 on Stations 2, 3, 7, 9, 11, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47 & 49. 
* Changed Cast 3 entries for above Stations to Cast 2. Sumfile entries for Cast 3 have same NO. OF BOTTLES as entries for Cast 2 in bottle file. Cast 3 entries also have "surface only" comments section. Assumed Cast 2 is rosette cast and Cast 3 is surface sample.
* No sumfile entries for Stations 96-99.

2.  BOTTLE file from web (no time stamp. file dated Feb 12, 1998)  
* Changed WHP-ID from I6 to I06SA.
* Merged DELC14 abd C14ERR from:
    /usr/export/html-public/data/onetime/indian/i06/i06s/original/20020410_KEY_I06S_ C14/20000825.072602_KEY_I6S/20000825.072602_KEY_I6S_I6S.C14 
    into corrected web bottle file.

* Station 12 casts 1 and 4 are missing CTD data including pressure for most entries. These casts have apparently valid water sample salinities, dissolved oxygens, CFCs, TCO2 and C14. Left data as is for WOCE format file (i06sahy.txt) but deleted casts 1 and 4 for exchange bottle file (i06sa_hy1.csv).

* Station 25 cast 1 has salinity type values in the THETA column, temperature type data in the SALNTY column, one decimal place salinity type data in OXYGEN column, and other strange values in other water sample columns. Quality flags are also strange, bottle salinity flag is 6 (replicate samples) plus some 0 and 1 flags with data values.  Left cast 1 in WOCE format file but deleted from exchange file.

* Other quality flag problems may exist. An exhaustive check has not been done at WHPOSIO.
    
3.  CTD
* Changed WHP-ID from I06S to I06SA in all CTD headers.
* Changed Cast numbers from 3 to 2 for same stations changed in sumfile.
* Temperature units were "DEG C" vs ITS-68 or ITS-90; changed to "DEG_C".  (Bottle file temperature labeled ITS-90.)

4.  New exchange bottle and ctd files made. Stations 96-99 not in exchange files.
* Sta 12, casts 1 & 4, and Sta 25 cast 1 not in bottle exchange file.

5.  New files checked with Java Ocean Atlas.

Moved I6S.C14 data from /usr/export/ftp-incoming to i06/i06s/original/20020410_KEY_I06S_C14. Data is a CSV file with  C14 data in it. I added the following header to the file  # I06S, 316MFCIVA_1, Key 

Bottle file has been converted to exchange and put online. The following lines were removed from the bottle file for the conversion because there was no navigational information in the sumfile for them.
 
STN 2 CAST 2
STN 3 CAST 2
STN 7 CAST 2
STN 9 CAST 2
STN 11 CAST 2
STN 15 CAST 2
STN 17 CAST 2
STN 19 CAST 2
STN 21 CAST 2
STN 23 CAST 2
STN 25 CAST 2
STN 27 CAST 2
STN 29 CAST 2
STN 31 CAST 2
STN 33 CAST 2
STN 35 CAST 2
STN 37 CAST 2
STN 39 CAST 2
STN 41 CAST 2
STN 43 CAST 2
STN 45 CAST 2
STN 47 CAST 2
STN 49 CAST 2

I have encountered an error while loading the s04hy.txt for our CFC DQE work for s04_I06. It turns out that the position of 'QUALT1' on header is aligned at the end of the flag columns instead of beginning of flag columns ... The sample and bottle numbers are still entirely -9, so I can't compare with the revised CFC data set I got from the CFC PI.

Tom Haine (now at Johns Hopkins) is the CFC PI for this cruise, and he has recently sent out the revised CFC data to the British data center. He says the center will forward the merged hydrographic data file to WHPO soon. Have you heard anything from BODC?

I noticed another particular thing in the sea file of I06S as follows:
i06shy.txt   
Sta.30 Cast 1 Btl.12 (1500m): ctd pressure, temperature and salinity reported as -9 yet with no flags

I just noticed some glitches in sum file of I06S cruise.
Sta.23 Cast 3 ROS (1st row) lat: 57 39.89 S instead of 59 39.89 S ?
Sta.23 Cast 3 ROS (2nd row) Max.Press: 295.4 instead of 295 4

added figs, linked tables and figs, data processing notes

I've reformatted the I06S CTD data files CIVA2_0491.csv through CIVA2_9991.csv 

I06S EXPOCODE 35MF103_1 CTD Stations 49-96 plus 998 & 999.

 1. Changed comma separated value files received from Steve Diggs November 15, 2000, to WOCE format CTD files.

      CIVA2_0491.csv   to   i06sb0049.wct
      CIVA2_0501.csv   to   i06sb0050.wct 
                       etc.                 etc.
      CIVA2_0951.csv   to   i06sb0095.wct
      CIVA2_0961.csv   to   i06sb0096.wct
      CIVA2_9981.csv   to   i06sb0998.wct
      CIVA2_9991.csv   to   i06sb0999.wct

 2. Plotted all files and ran wctcvt. No apparent errors.

 3. Sarilee Anderson has already reformatted Stations 1 - 48.  The two sets of reformatted CTD files should be put in to on zipped file for posting to the web.

Dave Muus, November 21, 2000

The quality of the Ba data from most WOCE legs in the Indian Ocean turned out to be quite  poor; far worse than attainable analytical precision (+/-20% as opposed to 2%). We recorded many vials which came back with loose caps and evaporation associated with that seems to be the primary problem.  The only hope I have of producing a decent data set is to run both Ba and a conservative element simultaneously and then relating that to the original salinity of the sample.  We will be taking delivery on a high resolution ICPMS here at OSU sometime this winter which would make the project analytically feasible and economical.  I do not presently have the funds in hand to do this and so have archived the samples for the time being. I don't think the WHPO would derive any benefit from the present data set.
KKF

The I6 (HELLIUM) data are from the 1996 cruise (CIVA-2 cruise). The CIVA-1 helium samples were bad due to sampling problems (the clamps on the copper tubes were not properly closed and most samples suffered partial reequilibration with the atmosphere...).

i06s.note        19981223WHPOSIODM

i06ssu.txt - MAX PRESS given in tenths of decibars (f6.1) instead of i5.   Consequently header adjusted to put extra space between WIRE OUT and MAX PRESS.  MAX PRESS values unchanged.

EXPOCODES not yet changed.

I have put the reformatted CTD files for I06S in the anonymous ftp area on whpo in INCOMING.  I compared all the files, but there were only 14 that were different from the originals I did in Sept.  I only put those 14 stations there.  There is also an i06s.notes file.

CTD stations 6, 10, 13.3, 14.2, 18, 21, 32, 40, 45, 47, 47.3, 48, 49, and 52 were truncated in transfer in the original files.  They are now complete and have been reformatted.

Completed reformatting the ctd files.  Only the headers needed information to make them complete.  Added NO. RECORDS= value, and changed the station and cast numbers.  The originator had all casts set to 1 and the station numbers (as pointed out by Lynne) were numbers like 11, 21, 33 where the first number is the station number and the second is the cast number, ie 33 is station 3, cast 3, etc.

In most cases the originator reported more than one cast.  There is not a standard in the files naming convention for this.  I named the files i06sxxxx.wct for the deepest cast - usually cast 1.  The other files were named i06sxxxx.x.wct, xxxx being the station number and the .x being the cast number.

Station 25 on I06S has columns out of order (temperature and salinity switched etc etc).  Can you please regrid all properties for I06S, leaving out station 25?  It's too much trouble for me to correct the data set right now.

Steve and Jerry - PLEASE keep this email in your comments for I06S which would be forwarded to a DQE or given to Dave Muus or Sarilee to fix before the data set is sent to a DQE.  

The data set should definitely be fixed before it is released to anyone else.  The problem is in station 25 cast 1, where the columns are in a different order from all other casts on the section.

The .sum file now conforms with our new format EXCEPT for the max press.  The original file had the maximum pressure to tenths (xxxx.x).  I left it that way. 

Files i06_sum.txt and i06_hyd.txt were reformatted to conform with what is, at this time, the WHP formats.   This consisted mostly of adding spaces and shifting data.  The following are other discrepancies that were found.  Some that were obvious were "corrected" others were left as is for someone else to determine what should be done.--Sarilee Anderson, 3 Feb. 1998

i06_sum.txt:
--record 136 longitude input as 29 60.0 - changed to 30 00.0
--record 420 max. pressure input as 288?2 - changed to 288.2
--records 516, 517, and 518 all had the date as 31393 - changed to 031393

i06_hyd.txt:
--SAMPNO - these are strange numbers 10, 20 30,40,1750,2000, as if they were desired depths (pressure) for sample.  Doesn't cause a problem, just strange.  There are even some that have F-20 as a sample no, these are usually the deepest sample(s).

--Station 12, cast 1 and cast 4 - these casts do not have  CTDPRS, CTDTMP, CTDSAL, CTDOXY, THETA, SILCAT, NITRAT or PHSPHT.  But they do have SALNY, OXYGEN, CFC-11, CFC-12, and TCARBN.  WOCECVT will not convert them because there are no pressures (depths)

--Station 25, records 720 to 731, sample 325 bottle 12 to sample 1600 bottle 1. data screwed up.  THETA, SALNY, OXYGEN, and SILCAT columns do not have the correct values.  QUALT1 flags not much help in determining what the problem might be.  Values aren't even close to what they should be.  Some values might be in the wrong columns, but that does not account for everything.

--Station 28, record 811 (last record in file) is incomplete.

The .hyd file stops at sta. 28, but the .sum file indicates there should be 52 stations.

In the following stations the cast number in the .sum file does not agree with the cast number in the .hyd file.

Station #s      cast #s in .sum          cast #s in .hyd
 2               1 and 3                  1 and 2
 3               1 and 3                  1 and 2
 7               1 and 3                  1 and 2
 9               1 and 3                  1 and 2
11               1 and 3                  1 and 2
15               1 and 3                  1 and 2
17               1 and 3                  1 and 2
19               1 and 3                  1 and 2
21               1 and 3                  1 and 2
23               1 and 3                  1 and 2
25               1 and 3                  1 and 2
27               1 and 3                  1 and 2  

I'm guessing the .hyd is correct and the .sum is incorrect.  But I did not change either of them.
