Data History

Permalink	Date	Person	Data Type	Action	Summary
329217	2002-03-11	Muus, Dave	TRITUM	Website Updated:	Data Online
Notes on P04C merging Mar 11, 2002 D.Muus 1. Merged TRITUM and TRITER values from http://www.soc.soton.ac.uk/soes/staff/wjj/p04trits.txt into bottle file from web (20010904WHPOSIODM) 2. Quality flag 2 assigned to all tritium values. 3. Made new exchange file for Bottle data. 4. Checked new bottle file with Java Ocean Atlas. 5. Put new exchange and woce format bottle files on-line.
329168	2002-02-27	Bartolacci, Danie	TRITUM	Submitted	Tritium data obtained, needs to be merged
I have obtained tritium and sigma tritium data for all 3 P04 legs from Bill Jenkins website. One file contains all 3 legs, not WOCE formatted, needs merging into respective bottle files. File is located /usr/export/html-public/data/onetime/pacific/p04/original/20020227_P04/TRIT_ALL_LEGS_JENKINS
329033	2002-01-17	Hajrasuliha, Adel	CTD	Internal DQE completed	See Note:
created .ps files, check with gs viewer. Created *check.txt file.
328984	2002-01-04	Uribe, Karla	CTD	Website Updated:	Exchange file online
CTD has been converted to exchange using the new code and put online.
328612	2001-09-27	Uribe, Karla	Cruise Report	Website Updated:	New txt version online
Documentation for all three p04s has been replaced with a newer version and put online.
328545	2001-09-07	Bartolacci, Danie	CFC/BTL/SUM	Website Updated:	Data Online
I have replaced the previously online bottle file for P04C with the bottle file containing newly merged CFC's. Data updates were sent by D. Wisegarver and merged by D. Muus. all previous files have been moved to original subdirectory and have been renamed. All references have been updated to reflect this change. Notes on P04C CFC merging Aug 29, 2001. D. Muus 1. New CFC-11 and CFC-12 from: /usr/export/html-public/data/onetime/pacific/p04/original 20010709_CFC_WISEGARVER_P04/20010709.165933_WISEGARVER_P04_tps10_CFC_DQE.dat merged into web SEA files as of Aug 21, 2001: P04C (20010327WHPOSIOKJU) One file contained new CFC data for all three legs. No SEA file QUALT2 words so added QUALT2 identical to QUALT1 prior to merging. New CFC data file appears to have SAMPNO and BTLNBR swapped with respect to .SEA file data. Checked that .SEA file SAMPNO same as CFC file "btlnbr" with respect to Sta#, Cast# and CTDPRS. 2. SUMMARY file (20010326WHPOSIOKJU) has "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 SUMMARY file unchanged. 3. Exchange file checked using Java Ocean Atlas.

328461	2001-08-21	Bartolacci, Danie	CFCs	Submitted	CFCs need to be merged into BTL file
I have placed the new file containing updated CFC values for ALL P04 cruises in the subdirectory called original/20010709_CFC_WISEGARVER_P04 located in the parent P04 directory. These data are in need of merging into the individual P04 bottle files currently online.
328327	2001-06-29	Wisegarver, David	CFCs	DQE Complete	precision outside orighnal WOCE standards; meets "relaxed" stnds
The precision of the CFC-11 and CFC-12 measurements fell outside of the original WOCE standards of 1% or 0.005 pmol/kg with an estimated precison of 1.3% or 0.006 for CFC-11 and an estimated precision of 1.9% or 0.002 pmol/kg for CFC-12. Estimates of presision were based on the median value of percent deviation for mean concentrations > 0.5 pmol/kg and median standard deviation for mean concentrations less than or equal to 0.5 pmol/kg. Due to bottle contamination experienced during the initial phase of the project, the calculated deep CFC concentrations were variable, in stpite of efforts to correct for the problem. The standard deviation of samples in the deep, presumable zero CFC concentration water was 0.01 for CFC-11 and 0.007 for CFC-12 during leg 1, but was reduced to 0.04 and 0.003 for CFC-11 and CFC-12 respectively by leg 3. This lever of scatter can be seen throughout the water column. Based on the precision of the replicate samples and the scatter due to bottle contamination, this data set does not meet the original WOCE quality standards [1.3% or 0.006 for CFC-11 and 1.9% or 0.002 pmol/kg for CFC-12], but does fall within the relaxed standards of 3% or 0.015 pmol/kg.

327375	2000-10-23	Toole, John	Cruise Report	Update Needed	complete e. version requested by J. Swift
Paper version on hand at WHPO
327019	2000-07-24	Salameh, Peter	CFCs	Update Needed	See note:
There are two problems with the TPS10 CFC data. The first has to do with contaminated bottles. Nearly all of the analytical equipment, including the WHOI 10-liter Niskin bottles used for the majority of the hydrographic work, were sent to Majuro in a shipping container which was severely contaminated with CFCs, probably originating from packing foams used for other equipment in the container. There were 4 types of bottles used during this cruise, each with a different initial CFC blank, and each cleaning up at a different (about exponential) rate. Ricky and I did our best to fit the blanks for each bottle type to an exponential as a function fo time. To give you some idea, the initial blanks (in pmol/kg) at the start of each leg for each bottle type were: Leg1 CFC-11 CFC-12 10 liter WHOI Niskin 0.047 0.019 2.4 liter Niskin 0.025 0.012 10 liter SIO Barron 0.047 0.019 Leg2 CFC-11 CFC-12 10 liter WHOI Niskin 0.022 0.005 2.4 liter Niskin 0.026 0.004 Leg3 CFC-11 CFC-12 10 liter WHOI Niskin 0.009 0.005 2.4 liter Niskin 0.006 0.004 10 liter Miami Niskin 0.004 0.006 When determining these blanks we also had the problem that CFC-free water was not sampled for all bottle types at all times, so some guess work was involved. As I write this, Ray reminds me that we have already written a detailed report on this. I have attached this as PostScript file "text.ps" if you would like all the details. The second problem I discovered recently when comparing the WHPO database with our CFC database, as part of the WOCE synthesis. For TPS10 leg3, I found a few values where the two databases do not match, and also quite a few samples where the WHPO file shows CFC values of 0.0 where we report no value. These were clearly merging problems at the old WHPO at WHOI. I have attached the list of mis-matches and a correct version of the tps10 leg3 CFC data. I will send the corrected data to the WHPO next week (see below). Please note that all the SIO TPS data (TPS10, 24 and 47) are still on the SIO 1986 standard scale. All the other SIO data at the WHPO are on the SIO 1993 standard scale. Early next week I will update the WHPO database with SIO 1993 values for the TPS cruises (the conversion from SIO 1986 to SIO 1993 requires dividing CFC-12 values by 0.9874 and CFC-11 values by 1.0251). If you would like, I will email you a copy of these data when I send them to the WHPO.
326778	2000-05-23	Key, Robert	BTL/SUM	Update Needed	See note:
1. in the sum file(s): No entry for station 8 or 215 (data exists in hyd files) Entry for station 77 out of order (data in hyd file in correct order) 2. in the sum AND hyd files: No entry for stations 1,2,84 or 216. Station and data entries existed for these in older versions of the files (32MW893-i.yyy) Data records for 119 bottles now "missing".
326613	2000-04-19	Bartolacci, Danie	DELC14	Website Updated:	P4C/E/W Changed to indicate no samples collected.

325815	1999-04-05	Diggs, Stephen C.	CTD	Website Updated:	corrected ctd data now OnLine

325800	1999-03-26	Ross, Andrew A.	SUM	Data Update:	see note:
I'm working with Lou Gordon on the GODS Pacific project. No doubt you'll be hearing more from me. In regard to the "P10 - Nitrate" note Lou sent to you the other day - the data listed under the "NITRATE" column is in fact the total of "Nitrate AND Nitrite" or N+N. You are correct in stating that to obtain NITRATE only, you must subract out the corresponding NITRITE value. Again, the units of umol/Kg are correct for all nutrients. To clarify, I obtained the P10 data (p10hy.txt) from the WOCE website that your PACIFIC data listing website linked - http://whpo.ucsd.edu/data/onetime/pacific/p10/index.htm. After downloading and checking cruise TPS10 (WOCE p04ehy.txt, p04chy.txt, p04why.txt) from the WOCE website, I've determined the same situation to be true. The data listed under the "NITRATE" column is actually NITRATE and NITRITE combined. The units of umol/Kg are correct for all the nutrients in the WOCE files.
