I dug out the original P6 data and can verify that the data on the WHPO website ARE in the stated units of micromoles per kilogram.
I pulled one station from each leg at random and in all cases, the phosphate, silicate, and nitrate concentations given in the WHPO site are approximately 97.56% of our original data. This is consistent with the conversion from micromoles per liter to micromoles per kilogram.
I am a PI of nutrients analysis on R/V Mirai BEAGLE cruise in 2003-2004 which revisited P06, A10, I03 and I04. I saw the temporal variation of nutrients on these regions, then I found a large decrease of nutrients concentration in the Pacific sector. It reminds me of a part of the cruise report as shown below.
I wonder that the concentration is stated in the unit of micro mol per kilogram in the data file. However, the data originator may have submitted in micro mol per liter and nobody converted them to micro mol per kilogram. If so, the big difference I found becomes relatively reasonable because P06 data becomes ca. 1/1.026.
Can you be track the nutrients data from the beginning? Do you have the paper version of data of P06? Or, would you let me know contact address of Dr. Joe Jennings who was a PI of nutrients data on P06?
Notes on P06C Feb. 19, 2003 D. Muus
1. Merged DELC13 from:
/usr/export/html-public/data/onetime/pacific/p06/original/
2001.01.22_DSTUART_P06_C13.DIR/whpo_p6c.txt
into current web bottle data file 20020516WHPOSIODM
2. Original DELC13 data file (whpo.p6c.txt) had following inconsistent
data entries:
Lab WHPID Sta Ca Niskin del-c13 flag
1 P06C 140 1 20 0.255 9
1 P06C 140 1 34 1.201 9
1 P06C 133 1 30 -9 3
The Station 140 values look good so changed flag from 9 to 3.
Changed flag for 133/1/30 from 3 to 9.
3. Made new exchange file for Bottle data.
4. Checked new bottle file with Java Ocean Atlas.

5. Made new exchange file for Bottle data.
6. Checked new bottle file with Java Ocean Atlas.
I'm looking at the data that is on the WHPO web site (at least a version of it that was on there earlier this year, please let me know if this is ok). I'm finding that there seems to be data in the file that actually shouldn't be there. I believe these were failed analyses that somehow got included in my data submission, whenever that was. For that, I apologize!
Fortunately, these spurious data points have a clear signature: they have a zero (and hence unphysical) helium concentration value. Thus any delhe3 would naturally be undefined anyway. You can eliminate these points by selecting only those delhe3 values that have non-zero helium.
Unfortunately, there is a bunch of them (45 to be exact). Below is a list of the spurious points :

I pulled the stripcharts for the P6 stations that Lynne had questions about. We did, indeed, have some problems with wandering baselines at a few stations and what appears to be a consistent leaking bottle at several others. The apparently leaking Niskin #24 was located at a depth at which there was a strong gradient in the other nutrients, so the leak is not readily apparent except as a persistent small nitrite peak at ca 1000 - 1200 db.
Station(s) Problem
101, 103, 104 Non-linear baseline meander
150, 154 - 159 Small real NO2 peak, always at Niskin 24 at 1000 - 1200 db (36 bottle rosette)
167 Bottle 24 definitely a leaker. Other nitrite values from bottles 22 - 36 affected by a baseline meander.
193 This high nitrite was due to a fluke computer problem. The value should be 0.003 vs 0.32. (Don't know if it's better to flag or change this datum.)
I would agree with Lynne that she should "zero them out" for the purposes of her plot(s), and we should ask her to flag them in the WHPO data set.
Documentation for this cruise has been updated.

3. Exchange file checked using Java Ocean Atlas.
I just 'put' p6c.tar.Z and p6w.tar.Z in the INCOMING directory at whpo.ucsd.edu.
I was looking at Jane Dunworth-Baker's Aug 29, 2001, message and her comment "sta 156 salt at 3db should be 35.5652" appears to be referring to CTD data not Bottle data.
The shallowest bottle on 156 is 23.7db. CTD salt at 3db is now 38.5652.
So this will be a correction not connected with the anticipated CFC merging.
I have edited the header information of the Exchange CTD files in order to conform with the new header variables decided by WHPO. Previous exchange CTD has been moved to original directory and new zipped file has been linked.
CTD and Bottle files in exchange format have been put online.
STUART, DANA would like the data PUBLIC.
Sorry about excluding the headers... should have included them in the body of the last message. Here they are:

Received 1997 August 15th.
Merged PCO2TMP data from A. KOZYR into hyd file. Updated hyd file is on-line.
Bottle: (tcarbn, pco2)
Merged TCARBN and PCO2 data into hyd file. Updated hyd file is on line. Merging notes in original subdir 2000.08.24_P06_CO2_KOZYR.
A. Kozyr data for p06c, p06w, p06e were placed together in the original subdir
2000.08.24_P06_ALL_LEGS_CO2_KOZY. Copied each data set to related p06 subdir for
merging.
Specific notes on TCARBN & PCO2 merging in p06w: hyd file had preexisting -9.0 values
for missing data. Had to merge Kozyr data, then extract all data, replace -9.0
values with -999.0 and remerge. Extracted and edited file called alldata_edt.dat.
Bottle: (delc14, c14err)
Merged delC14 and C14err data into hyd file. Updated hyd file was put on line. Merging notes in original subdir 2000.05.10_P06_C14_KEY.
All C14 data/notes for P06 legs p06c, p06e, p06w came in one dir. from Bob Key (2000.05.10_P06_All_LEGS_C14_KEY).This data dir. was copied to each cruise leg subdir. The edited data file, p06_c14_edt.dat, was reformatted and prepared for merging, then copied into each cruise subdir. NOTE: One entry in this file was erroneous. The entry had a station value of b2532. I reviewed the bottle data file and determined this was meant to be station 32, cast 1, sample 25; edited this entry for merging. Also, the Key data file header reports the file format is station, cast, bottle....; This format does not match the bottle file format. C14 data was merged as station, cast, sample....
Specific merging notes for p06w: There was some existing C14 data in the previous hyd file version. This data is the same as the updated Bob Key data to be merged, however it was not a complete data set. Merged new c14 data over existing data. Preexisting data was for stations:194,205,210,214,229,234,239.
I have moved all three legs of P06 CO2 data into the parent P06 original directory. Data (TCARBN, and PC02, PCO2TEMP) were sent by Alex Kozyr on 2000.08.24. Email accompanies data in /onetime/p06/original/2000.08.24_P06_ALL_LEGS_CO2_KOZYR. Data are public and have not yet been merged. "to merge" table has been updated to reflect this.
I have put the long waited and finally released by Doug Wallace final CO2-related data files for the Pacific Ocean WOCE Sections P6E, P6C, and P6W to the WHPO ftp INCOMING area.
The C-14 section captures most of the features for P6, however, I think that you only have about half the data. The details of how this could happen are too long to worry about, but it is probably my fault. I have attached an ascii file with all of the results.
One problem is that the current hydro file at WHPO does not include data for station 3. Early versions of the sea file included stations 1-3, but these locations were re-sampled and subsequently 1-3 declared "test". As early as 1995 I lobbied to get station 3 data added back into the official files, and it was for awhile. When the far eastern portion of the secion was re-sampled, some of the tracers which had been sampled originally were not re-collected. The reasons varied. With respect to C-14, cutting station 3 is equivalent to discarding ~10K worth of analyses and it creates a very important hole in the section. The problem is less severe (due to sampling density) for carbon parameters, but it exists. I do not know the whether or not H-3 was collected on any of station 1-3.
I found no glaring problems with the bottle data from station 3 and think that the C-14 data alone justifies keeping this station in the official WOCE data file.
When the section is remade, it is important that the contour labels be attached to the C-14 minimum around 2300m at the eastern end of the section. The fact that the minimum is segregated into eastern and western lobes is one of the most important results from the deep Pacific radiocarbon program. I also believe that the deep/abyssal relative max around 102W is real and probably indicative of a weak western boundary flow along the flank of the ridge.
WHPO: I have ftp'ed a copy of the attached file to your INCOMING directory
called P6-C-14.dat
My name is Danie Bartolacci, and I'm a programmer/analyst working for both theWHPO and Lynne Talley. I'm trying to track down information about C-13 measurements taken for some WOCE Pacific lines. I've recently corresponded with Bob Key who directed me to you.
My understanding from Bob is that processing of C-13 for these lines is finished. Is it possible to obtain the data and/or an update on their status for the following cruise lines? Any information you can provide would be greatly appreciated! Thank you for your time!
