Carolina and I were examining a weird data point that showed up in a
data set she was preparing for the DPO textbook. The value in
question was obviously wrong. I told Carolina that it looked like a
decimal point error. I was wrong.
This morning Kristin helped me look at the ODF data from this cruise.
Somehow the CTD oxygen value for this cruise/station/cast/bottle got
scrambled. It is correct in the ODF records. It is wrong in the
CCHDO on-line data file i07n_hy1.csv.
The correct CTDO value is 188.4 umol/kg, not 910.1 umol/kg. A CCHDO
data person should change the value in the CCHDO on-line file.
Yesterday, 8/21/08, in accordance with this recommendation, Steve and
I corrected this value in the data files. We re-made the Exchange and
netcdf files and replaced all of the online bottle files on the
website . The files were then downloaded again from the CCHDO website
using a variety of analysis software and everything seems to be in
order.
The U.S. WOCE Indian Ocean Survey consisted of 9 cruises covering the period December 1,1994 to January 22,1996.All of the cruises used the R/V Knorr operated by the Woods Hole Oceanographic Institute. A total of 1244 hydrographic stations were occupied with radiocarbon sampling on 366 stations.
I Replaced one decimal place DELC13 with two decimal places. Put new file online, made new exchange and netcdf files.
The c14 value of 11.7 (see 2 previous emails) was correct. I left it as is re Bob's email.
The value in my database for C13 on I7N 764-1-34 at 61.8dB is 0.064 o/oo (Ann, the c13 id num is 13708).
The 11.7 (actually 11.67) is the Delta C14 value with error of 2.88 for the same bottle.
Both the c13 and c14 are flagged "2".
We're plotting sections from I07, and have a question about delC13:
I07N, station 764, bottle 34 at 61.8 dbar: value is 11.7.
This looks different from the surrounding values (vertically and horizontally) so we just want to check if it's OK.
107N, 709-1-12 C14:
I have no idea where the value of -1.9 originated. The NOSAMS final report for this sample as well as all my records have the value of -185.00 +/- 3.24 , flag=2 for this sample. Regardless of the source, good catch. In case it was more than just a minor typo somewhere along the line, I've attached the other values for that station. Note that the dump routine I used drops trailing 0's so -185.00 comes out as -185, etc.
SE and Lynne Talley noted that a "bad" DELC14 value on sta. 709, bottle 12, 2793.6db. I checked the original file sent by Bob Key, and found that the value was indeed wrong. Changed the value in the online file, made new exchange and netcdf files.
We're plotting Indian Ocean sections, and found an unflagged bad C14 value:
I07N, station 709, bottle 12, 2793.6 dbar: value is -1.9, all surrounding values are very different. QUALT1 and QUALT2 flags are 2.
Bob - is there a better value that should be in the file?
If not, should we change the flags to 4, or delete it?
CTD exchange, netcdf and inventory files were updated.
Rezipped all ODF CTD files and replaced all current CTD files with updates. Put new zip file online. Needs to have exchange and NetCDF files created.

CTD and bottle exchange files were put online.
ODF has discovered a small error in the algorithm used to convert ITS90 temperature calibration data to IPTS68. This error affects reported Mark III CTD temperature data for most cruises that occurred in 1992-1999. A complete list of affected data sets appears below.
ODF temperature calibrations are reported on the ITS90 temperature scale. ODF internally maintains these calibrations for CTD data processing on the IPTS68 scale. The error involved converting ITS90 calibrations to IPTS68. The amount of error is close to linear with temperature: approximately -0.00024 degC/degC, with a -0.00036 degC offset at 0 degC. Previously reported data were low by 0.00756 degC at 30 degC, decreasing to 0.00036 degC low at 0 degC. Data reported as ITS90 were also affected by a similar amount. CTD conductivity calibrations have been recalculated to account for the temperature change. Reported CTD salinity and oxygen data were not significantly affected.
Revised final data sets have been prepared and will be available soon from ODF (ftp://odf.ucsd.edu/pub/HydroData). The data will eventually be updated on the whpo.ucsd.edu website as well.
IPTS68 temperatures are reported for PCM11 and Antarktis X/5, as originally submitted to their chief scientists. ITS90 temperatures are reported for all other cruises.
_______________________________________________________________________
Changes in the final data vs. previous release (other than temperature and negligible differences in salinity/oxygen):
S04P: 694/03 CTD data were not reported, but CTD values were reported with the bottle data. No conductivity correction was applied to these values in the original .sea file. This release uses the same conductivity correction as the two nearest casts to correct salinity.
AO94: Eight CTD casts were fit for ctdoxy (previously uncalibrated) and resubmitted to the P.I. since the original release. The WHP-format bottle file was not regenerated. The CTDOXY for the following stations should be significantly different than the original .sea file values:
009/01 013/02 017/01 018/01 026/04 033/01 036/01 036/02
I09N: The 243/01 original CTD data file was not rewritten after updating the ctdoxy fit. This release uses the correct ctdoxy data for the .ctd file. The original .sea file was written after the update occurred, so the ctdoxy values reported with bottle data should be minimally different.

Hi Jim,
Sure, I would be glad to look over the Indian Ocean data for you. Sarilee has started plotting up I01 for me to start on. - Arnold
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.
Merged TRITIUM, TRITER, HELIUM, HELIER, NEON, NEONER, DELHE3, DELHER from Z. Top into hyd file. Updated hyd file is on-line. Merging notes in original subdir 1998.12.18.I07N_HE_ZAFER_TOP.
Data from PI did not have cast numbers. Verified all cast numbers were from cast "1", and
entered cast into data file.
Split data into individual data files for each parameter and removed blank spaces where no data was entered. Had to do a lot of reformatting for each file.
I had verified with PI in a previous correspondence (I09N) that all data submitted was considered acceptible, and should be flagged as '2'. Flags entered into data file for merging.
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 have put the final CO2-related data file for the Indian Ocean WOCE Section
I7N to the WHPO ftp INCOMING area. There are two CO2 parameters in the file:
Total CO2 and Alkalinity with quality flags.
This is a follow-up to last month's message requesting that all of our Pacific and Indian Ocean CFCs be made accessible to the public. Our cruises are; (Pacific) P17C, P1716S, P06E, P19C, P17N, P21E, and (Indian) I09N, I05W/I04, I07N, I10.
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.

My helium-tritium data from IO legs I1-I7N and I9N may now be made
public . It should be kept in mind though that we are working on the
synthesis ; some modifications may occur. Also there are some papers are in
progress; interested parties should check with the tracer group (Schlosser,
Jenkins, Lupton, Top)
according to an email I received last week, the I7N data (CTD, O, S, nuts) should all be public now.
This is Ashwanth Srinivasan from Noble Gas Isotope Lab , RSMAS, Univ of Miami. We have submitted four files, i7he.txt, i9he.txt and i1he.txt and readme.he to the incoming directory at your ftp site. These files contain tritium, helium and neon data from WOCE I7N, I9N and I1 cruises. These data are preliminary and proprietary and the format is explained in the readme.he file.
