I am writing this mail to report an possible erroneous station location of P3-1985. We are now reoccupying P3 stations. When we occupied stn.155 following the .sum file of P3-1985, we measured the water depth at the station only as 900m though .sum file of P3-1985 reads 2107m. Find an sea beam sounding records of R/V Mirai with original station locations as an attached file. In the plot, station 155 is located in the north of the next station of 154. Also CTD file of P3-1985 shows the maximum pressure as 2128db at the stasion 155.
As the result, it seems that the location of station 155 in .sum file of P3-1085 is erroneous.
I have the handwritten "science logbook" for both legs of P3-1985. I believe this logbook was the source of the "official" positions. It contains the same (probably incorrect) location for stn. 155 as the sum file.
The only clue as to what went wrong is a notation on the position "DRT 03 50", which I believe must mean that the Satnav system had been dead reckoning without a good fix for 3 hours and 50 mins. Based on Masao's graphic, it would seem that the ship was positioned correctly in between stns 154 and 157, but the recorded position was erroneously taken from the dead reckoning Satnav computer. (???)
Exchange CTD files re-made and placed online from Sarilee's data update (2001.10.09).
Text documentation for this cruise was replaced with a newer version. PDF version of documentation has now been put online.
SE found 5 stations missing from the CTD zipped files. Found the stations, reformatted, added headers, and rezipped files. The missing stations were 1, 257, 310,365, and 388. The old files were renamed and moved to the original directory. New files were put online.
Added stations 1, 257, 310, 365, and 388 to the ctd files. They were discovered to be missing by SE.
Reformatted the data files to WOCE format and added headers to those five stations.
Sarilee Anderson
As per SE there are 4 CTD station files missing from the on line CTD zipped file. This matter is being investigated at this time.
SE wrote-
Could you check on 4 stations for me in p03? Stations 388, 365, 257, and 1 used to have ctd data ( from Lynne's original work that I am using as a template for making these new plots), but these 4 are not in the dataset I downloaded from the web site. If you could give me information on these, I can either wait for the data or go ahead without them. There is bottle data for these stations, but no ctd data.
It was found that the ctd station file for station 320 was mistakenly labeled as station 310. The file name was corrected, and new zipped ctd files are online. Since station 310 is missing from even the original files forwarded from WHOI, ODF has been contacted in an attempt to obtain a new ctd data set, or at least the station 310 file.
New CFC's were merged into the bottle file for each leg. These new files have replaced current online files. updated (reformatted) sumfiles have also replaced current versions.
Below are notes from merging CFC's into P03a and P03b:

Notes on P03 CFC merging Sep 6, 2001. D. Muus
1. New CFC-11 and CFC-12 from:
/usr/export/html-public/data/onetime/pacific/p03/original/ 20010709_P03_CFC_UPDT_WISEGARVER/20010709.165533_WISEGARVER_P03/
20010709.165533_WISEGARVER_P03_tps24_CFC_DQE.dat
merged into web SEA files as of Sept 6, 2001: 20000703WHPOSIODMB
File names changed from p03a (second leg) to p03w and p03b (first leg) to p03e
One file contained new CFC data for both legs.
No SEA file QUALT2 words so added QUALT2 identical to QUALT1 prior to merging.
CFC file has 3 digit sampno as Cast# & Bottle# while .SEA files have SAMPNO as Bottle# only. CFC file has -9 for Bottle numbers. Changed CFC files by deleting Cast# portion of sampno in order to merge.
2. SUMMARY files: Leg 1 (20010326WHPOSIOKJU)
Leg 2 (no version code)
have "INT" (interpolated?) as NAV entry numerous times. "INT" not a NAV code per WOCE Manual.
EVENT CODE is BO, EN, BE rather than normal sequence of BE, BO, EN.
All three position and time entries for each station are identical since this is a Pre-WOCE cruise. Left NAV and EVENT CODEs unchanged.
EXPOCODEs for Leg 2 SUMMARY file changed from 31TTTPS24/2 to 31TTTPS24_2.
EXPOCODEs for Leg 1 SUMMARY file already okay as 31TTTPS24_1.
3. Exchange files checked using Java Ocean Atlas.
I have placed updated CFC values into the P03/original directory. These files were sent by D. Wisegarver on 2001.07.09 and are ready for merging.
CTD and Bottle files in exchange format have been put online.
On TPS cruises which were sampled for TCO2, there were problems with precision and accuracy. These data have never been reported to either me of CDIAC. Feely's group did what sampling there was for the various carbon parameters. I believe that he does have alk values for at least one of the three TPS lines. Note that carbon data from the Japanese zonal line(s) is available from Feely (at least he has the data) and permissions.
Bottle: (helium, delhe3, qualt1)
Re-merged delhe3 and helium into both P03 legs (sent by L. Evans, different flags) replaced online files, updated webpages to indicate the change. As per J. Swift, 1999.10.25 email left these files as entirely public and unencrypted.
Merging Notes for p03 legs 1 and 2.
-Copied current bottle files from p03/p03a directory. Leg 1(p03bhy_complete.asc) and leg2(p03ahy_complete.asc) were encrypted and needed to be unencrypted.*NOTE* individual legs have different passwords for encyrption!
-Converted the Evans' csv helium files to woce format for ingesting into David Newton's mrgsea program. Used perl script convlupton.pl for this.
Two new edited files named: p3leg1woce_edt.txt
p3leg2woce_edt.txt
-Used Newton's mrgsea program to merge HELIUM and DELHE3 into both bottle files. Added date/name stamp.
Output files in this directory are named:
p03ahy_complete_delhe3_he
p03bhy_complete_delhe3_he
-ran wocecvt on both files:
p03ahy_complete_delhe3_he - no errors detected.
p03bhy_complete_delhe3_he - no errors detected.
-renamed files p03*hy_complete.txt and replaced current files. According to data detail 1999.10.25 J. Swift indicated that no Pre-Woce data from p03 should still be encrypted.
there is no reason that any data from the "pre-WOCE WOCE lines" (P1, P3, A16, etc.)
should be encrypted.
now has an encrypted version of the bottle data file that contains
helium and tritium in addition to the public version of the bottle file.
I just received tritium data for P01 and P03 (the old tps47 and tps24 sections) from Miami. I will ftp them to your incoming and Danie can merge them at some point.
I am ftping a file with the CFC data from Ray Weiss, courtesy of Peter Salameh, for the two old cruises TPS47 (P01) and TPS24 (P03). I will have Danie merge them and then the final files should be placed in the WHPO public site. I will also contact John Lupton about helium data and the Miami lab about tritium data for the same cruises.
