I've placed a new PDF version of the cruise report:
p15sado.pdf
into the directory: onetime/pacific/p15/p15s/p15sa/ .
It includes both CTD and Carbon Parmeter reports, summary pages and CCHDO data processing notes, as well as a linked Table of Contents and links to figures, tables and appendices.
The previous online version was renamed and moved to the "Original" dir.
The short answer is that those tritium results are definitely real! I've enclosed a few sections, including P15S for perspective. Those high values at ~200 m are the Fine/McPhaden tritium tongue from the northern subtropics.
Hi Bill (Jenkins) - can you check on several tritium values for the southern ocean
occupation of P15? (This is the 1990 NOAA Malcolm Baldridge CGC-90 cruise.)
What I notice about these three is that they are very high for the given
potential temperature. On the three stations, there are also no tritium
samples at shallower bottles. If their temperatures were up around 27, which
would be possible if the samples were actually from shallower bottles, then
the values would fall in with all the other tritiums from this section.
So is it possible that these should have been assigned to shallower depths
than 196 or 194?
Sta. tritium theta pressure
66 1.117 13.694 196.
67 1.259 12.962 194.
68 1.860 14.413 196.

At the direction and guidance of Lynne Talley, this cruise was moved from PR32 to
the onetime directories and renamed P15S because it more closely follows the P15S onetime line than any repeat line.
A new directory for this cruise was created. All files have been edited to reflect change in line number and exchange, netcdf, and station track files have been remade. New web files have been generated also.
This cruise needs to be changed in the data base before it will link on
the onetime site. Previous directory (pr32_a) has been zipped as an original copy of the data and it's file history and therefore will no longer link from the repeat site. A readme file will point users to new directory.
Lynne- I wrote Steve et al. about remaking the maps to include this station track (and sent them the track image) so it should be up toward the top of his queue (I think he's crunching on some code for Jim before he gets back at the moment, so I'll ping again when he comes up for air).
After much tinkering, the CTD files have been converted to both exchange and netCDF formats. Previously these files would not convert using current software (many errors, core dumps and JOA crashes). After different edits to the original ctd station files (*.wct files) It was found that the empty column for header NO. OBS was causing errors. This column was removed for the purposes of conversion (was retained in original .wct station files). Also previously online sumfile contained missing/wrong information had needed edits (see below).
Files now pass JOA and inventory files appear correct. These files have been zipped and added to the parent directory. Previous sumfile has been moved to the original directory. Web pages have been remade and link correctly.
Station track files have also been made and linked correctly.
This cruise does not come up on RCS at this time, therefore this readme file will be sent to document edits in lieu of RCS.
I have converted the ctd files to both exchange and netcdf files, however the conversion was suspect. Files have not been checked with JOA yet.
Two ctd station station files needed editing:
station 13 cast 3 needed cast header edited from 2 to 3.
station 62 cast 2 needed cast header edited from 1 to 2.
All files had the name/date stamp removed.
In sumfile for purposes of conversion:
station 64 cast 1 needed depth changed from blank to ----
station 40 cast 1 needed depth changed from blank to ----
SECT ID was changed from PR15S to PR32. This sumfile replaced the current online sumfile (depths were left at -999 in online version)
Formatted and added QUALT flags to file received from Kristy McNicols.
Notes:
In June I received the ctd data from Kristy McNicols. I converted to WOCE format.
Since this was a pre-WOCE cruise there were no QUALT flags. I assigned a QUALT flag of 2 to all pressure, temperature and salinity values and since there were no oxygens a 9 for oxygen.
Many stations have more than one cast so I named the files
pr32a0011.wct - cast 1
pr32a0011_2.wct - cast 2
pr32a0011_3.wct - cast 3
The individual casts are every decibar instead of every other decibar.
Took bottle data sent by Bullister to Lynne Talley and put into WOCE format.
There were zeroes for the QUALT1 flags for CTDSAL and SALNTY. Asked Bullister about this. See his e-mail below.
Talked to Lynne, and we decided they could be assigned a flag of 2.
See e-mails below.
File contains data for press, ctdtmp, ctdsal, salnty, tritum, triter, delhe3, delher, helium, helier, neon, and neoner.
There was a difference in the bottle and ctd cast summary for stations 0, 1, and 2. After comparing the depths I determined that the bottle file needed to be changed to agree with the summary file. Converted the CTD cast summary file retrieved from ftp site, ftp.pmel.noaa.gov to a WOCE formatted .sum file.
The cast numbers were sequential (0-110) throughout the file. Using the sum file I was able to determine (I hope) the correct cast number for each station.
Sarilee - I agree - set the flags to 2 and include a note in the documentation. The doc file will be scanned from the pdf.
What do you want me to do about this. I think we could include a note in the documentation that we set the QUALT1 flags to 2 since this was a pre-WOCE cruise and no quality flags were assigned by the originator.
I checked with Kristy McTaggart, who did the CTD work on the cruise. This was a pre-WOCE cruise and no quality flags were assigned to these data. Assigning them a WOCE flag of 2 would imply they had undergone this type of quality evaluation.
I put this header on the original file: CGC90 (extracted 22 May 2002, J.Bullister) "f" is WOCE quality flag (set to 0 if not available) -9 represents missing value
If this doesn't work, I can re-extract the file and not include a flag column.
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.
