    Note:
    I have put the file CCHDO_1.zip on MEDS ftp site for you to download. 
    
    Most of the meta data that we have is embedded in the surface parameter fields of the data record. Once you have had a look at the format and the available information, I can try to track down any further ancillary data that you may need.
    
    All of the data arriving here is put into our inhouse format.
    
    For the 1993-16 cruise aboard the Ak Nesmeyanov, I have the following profiles only,
    
    Water Property Data includes:
    C	CTD Pressure

    Date: 2004-12-16
    Data Type: NITRIT
    Action: Data Update:
    Note:
    If we can assume that nitrite should be zero for these samples, then nitrate needs to be increased by nitrite values:

  • Bullseyes Lynne Talley

    Date: 2004-12-13
    Data Type: NITRIT
    Action: Data Update Needed
    Note:
    Frank, Howard, and WHPO:  looks like there are some nitrite bullseyes on P15 that we're just catching now, since we hadn't made full depth sections before.  (The atlas will have sections only to 1000 meters.)  These most likely need to be flagged 4. 
    					
  • decimal places corrected, data remerged Sarilee Anderson

    Date: 2003-08-15
    Data Type: CFCs
    Action: Website Updated:
    Note:
    SE noted that the cfcs for this line were only to two decimal places. I remerged the cfcs, put new file online, made new exchange file, and sent notes to Jerry.
    
    
    Aug. 15, 2003
    
    It was brought to my attention by SE that the CFC11 and CFC12 values were only to two decimal places.  I checked the original file 20010709.173723_WISEGARVER_P15N_p15n_CFC_DQE.dat found in original/
    20010709_CFC_UPDT_WISEGARVER_P15N_ALL_LEGS.  The cfc's were reported to three decimal places.
    
    The original .hyd file had columns for the cfc's and had -9.00.  The mrgsea program, when merging data into already existing columns, does not change the precision.  So when the updated cfc's were merged only two decimal places were retained.
    
    I copied the file, setting the cfc's to -9.000 and remerged the CFC11 and CFC12 into the online file 20030429WHPOSIOSCD.

  • Problem with station 31 Lynne Talley

    Date: 2003-07-28
    Data Type: BTL
    Action: Data Update:
    Note:
    We found a probable problem at station 31.  The same in the WHP file listed at 5 dbar, is sample number 1 (rather than being in the 20s), and salinity, nutrient values are like those of sample 2, which is at 5883 dbar.  So it looks like the reported pressure for 31/ sample 1 is incorrect.  Can you (Frank Whitney) confirm?
    
    
    On July 28, 2003 Frank Whitney:
    
    You are correct that the pressure is incorrect.  I will try to recover this data point from original files.

    Date: 2002-07-16
    Data Type: CTD
    Action: Website Updated:
    Note:
    CTD was converted to exchange and put online. CTD files did not have matching station names with sumfile and bottle file. They had a preceding W that was removed from the original CTD files before the conersion. NetCDF files were made.

    Date: 2002-07-16
    Data Type: CTD
    Action: Website Updated:
    Note:
    CTD was converted to exchange and put online. CTD files did not have matching station names with sumfile and bottle file. They had a preceding W that was removed from the original CTD files before the conersion. NetCDF files were made. 94030180.WCT was not included in conversion because of lack of navigational information in the sumfile.
    					
  • CTD cast numbers do not match SUM file Danie Bartolacci

    Date: 2002-03-20
    Data Type: CTD
    Action: Update Needed
    Note:
    CTD station files for this cruise contain station numbers that do not match those station numbers contained in the summary file. No CTD exchange files have been generated at this time. Station  numbers need to be resolved/corrected.
    					
  • new cfcs merged into online btl file Dave Muus

    Date: 2001-10-29
    Data Type: CFCs
    Action: Website Updated:
    Note:
    Merged July 2001 CFCs into bottle file and placed new woce format and exchange format files on web. Changed Quality Code 1 to 9 where appropriate.
    
    1. New CFC-11 and CFC-12 from:
    
         /usr/export/html-public/data/onetime/pacific/p15/p15n/p15na/original/
          20010709_CFC_UPDT_WISEGARVER_P15N_ALL_LEGS/
          20010709.173723_WISEGARVER_P15N_p15n_CFC_DQE.dat
        
         merged into SEA files from web Oct 17, 2001.
          (20000908WHPOSIODMB) for P15Na
    
        Prior to merging:
          Changed all "1"s in QUALT1 to "9"s and then copied QUALT1 to QUALT2.
          Changed all missing values for DELC14 from -9 to -999.0.
    
    
    2. Summary file modified by putting Station P13 Cast 1 before Station 13 Cast 2 BE and putting Station P18 Cast 1 before Station 18 Cast 2 BE. Both were between Cast 2 BE and BO in correct time sequence but wocecvt "skipped" both casts and the exchange conversion duplicated both casts. Now in correct cast sequence but out of sequence for times.  Both wocecvt and exchange conversion okay.
    
    3. New exchange file checked using Java Ocean Atlas.

    1. New CFC-11 and CFC-12 from:
    
    /usr/export/html-public/data/onetime/pacific/p15/p15n/p15na/original/ 
    20010709_CFC_UPDT_WISEGARVER_P15N_ALL_LEGS/ 20010709.173723_WISEGARVER_P15N_p15n_CFC_DQE.dat 
    
    merged into SEA file from web Oct 17, 2001. 
    (20000817WHPOSIODM)
    
    Prior to merging:
    Changed all "1"s in QUALT1 to "9"s and then copied QUALT1 to QUALT2. Changed all missing values for DELC14 from -9 to -999.0. 
    
    Found duplicate sample number used for two different bottles: 
    
    Sta Ca Sample# Bottle# Pressure
    111 2 2552	13	1500.4
    111 2 2552	12	1749.2
    
    No CFCs taken from either bottle, but TCARBN and ALKALI were measured and the values for Bottle #13 (2325.6 & 2409.9) had been merged into both bottles. Corrected Bottle #12 TCARBN and ALKALI values (2334.5 & 2417.9).
    
    Station 108, Cast 9, Sample 2492, Bottle S10 has CTDPRS = -9.0. 
    All other samples also -9. Bottle quality code is 4 "did not trip correctly". CTDSAL quality codes are 2 while all other quality codes are 9. Changed CTDSAL quality codes to 9.
    
    2. New exchange file checked using Java Ocean Atlas.

  • btl file reformatted, see note: Danie Bartolacci

    Date: 2000-08-18
    Data Type: ALKALI/TCARBN
    Action: Data Update:
    Note:
    Bottle: (tcarbn, alkali, qualt1)
    
    Total alkalinity and Dissolved Inorganic Carbon have been merged into P15N_a and P15N_b by D. Muus. In doing so, he removed the PRS01 and PR06 stations from the P15N_a bottle file. This creates a missmatch between the current P15N_a sumfile and the new bottle file, since the sumfile has retained PRS01 (but not PR06). PR06 and PRS01 have been split off into separate sum and bottle files for this cruise and need to be put online. This matter should be rectified, and correct stations be placed in the P15N files before any further events take place on this line.

    For your information, John Garrett has retired and I am the custodian of the P15N data.  The data (CTD and bottle data) have been processed and submitted to the WOCE Hydrographic data Centre.  I have absolutely no objections to you making use of the data.  Please request the data from the data centre at Scripps.  I will send a copy of this note to Lynne Talley so she will know to expect a request from you.  The data are listed in the centre as being proprietary and to be released only with permission of the owners.  I don't understand why this is so and would much prefer that the data be made available to anyone on request.
