CTD and bottle file have been converted to exchange format and put online. Bottle woce checks indicate pressure inversion problem, sumfile clean of errors. BTLNBR column in bottle file was reversed, problem was corrected. NetCDF files were created accordingly.
eThere were not enough Q1 flags for the number of parameters with ***'s. After looking at the data it was obvious that the CTDSAL and CTDOXY were the parameters that should not have the ****'s Deleted the ***'s for CTDSAL and CTDOXY. There were 5 parameters with ***'s, but there were only 3 Q1 flags. After looking at the data it became obvious that the CTDSAL and CTDOXY should not have ***'s. Removed the ***'s from CTDSAL and CTDOXY
Replaced ctd .zip file with file received from Lynne Talley. She reformatted all ctd files to remove blank line that was at the end of each file. No changes to data or flags.
Just a note for the files - the deep CTD data from stations A7-A13 on p02w has a lot of problems. Most of the profiles have large sections with both temperature and salinity flagged "6". When I compute potential density (sigma 0, sigma 4 and neutral density), it appears that the chunks of data surrounding these flagged portions are also suspect, leading to marked deep density inversions (over many tens of dbars). I don't have a way to do rigorous quality control or reprocessing of these data. I also don't have an easy way to determine what additional parts of each station's data should be flagged. This is just a heads up to anyone planning to use these data that they appear to have quite major problems. And if there is a data quality control queue, it might pay off to have a data set like this near the top, since it clearly has problems. For the printed atlas, we will just do judicious hand editing of the inverted contours in density.
I have unencrypted the bottle and ctd files for this cruise as they were released to the public by Yoritaka on 2001.03.09. Index page has been updated to reflect this change.
I would like to consent to open Bottle_S/O2 and CTD data on P2E and P2W to the public as PI. Then, would you please change some information on the summarized table of WHP one time cruises on web as follows; P02W; CS: Iwanaga, Mizuno -> Iwanaga/(HD)MSA SHIP: SYOYO -> SHOYO
With regard to the hydrographic data collected by Japanese groups, I found that the present status of availability of the data for P02E and P02W appeared as 'NP' in the listings of WHPO web site. I believe they should be ready to be made public. Have you had any contact to or from Mr Yoritaka, the present contact person for both lines? I will be pleased to ask him to confirm that the data are to be public, if necessary.
Steve - I took Yoritaka's p02wsu.txt file and got it into the right column format. some of the information in it has changed slightly from the previous version. Most importantly, lat and long are now in degrees and minutes. I have place p02wsu.txt in my ftp area on whpo.ucsd.edu
I've replaced all of the p02.sum files (p02w, p02e, p02c) and updated the table to reflect this. In the case of p02c and p02e the sum file changes (via Lynne)were correcting the occurrances of the old line number designation with the new line number designation, and (by me)replacing the slashes in the expocode to underscores. (See Lynne's emails below) In the case of p02w the .sum file changes made (by Lynne) were converting decimal degrees into degrees and minutes in the lats and lons; the time was converted to GMT; station no. now has place holding zeros; cast type was changed from CTD to ROS; and height above bottom, wire out, and no. of bottles columns were also added. This conversion has shifted columns, however I ran sumchk on it with no errors. Slashes in the expocode were also replaced by underscores. I have also replaced the corrupted P2E119.WCT file with Lynne's updated version, and updated the table to reflect this. The table was also corrected to reflect the *bottle* data file being encrypted, NOT the .sum file (previously the table indicated the .sum file was Non-public and the bottle file was public).
First, there are only 3 flags for each measurement, but there are 5 potential parameters that could be flagged. We *think* that the flags are for CTDSAL, SALNTY and OYXGEN. Could you confirm this please? Second, are these data to be made public? Right now they are encrypted on our website. Please let us know. Finally, I have no documentation for this cruise. Do you have any that could be transmitted electronically?
I have changed 3 of the P02 lines. The new one is P02W (492SSY9411_1) SHOYO, which now has a bottle data file with Salts/O2 only. This file is encrypted/non-public. It is also the 4th occupation of PR27, and that table now has a link directly to the datafiles in the onetime section. The line that *was* P02CE, is now P02E. The line that *was* P02W is now P02C. All tables and files have been updated (along with all maps) to relfect these changes.
