P1C



I. CRUISE NARRATIVE
   (Masao Fukasawa - Tokai University)

P1C cruise was a leg of MR9905 on the board of Mirai of JAMSTEC, and was 
planned as part of the collaboration program between SAGE (Sub-Arctic Gyre 
Experiment: a Japanese ocean science program funded by the Science and 
Technology Agency) and IOS (Institute of Ocean Science, Canada) to re-visit 
WHP P1 which was previously occupied by United States in 1985.  As it has 
been 15 years since P1 was observed last, any possible climatological change 
may occur in the water column structure.  Thus, P1 revisit cruises were 
called for.

The original purpose of the cruise was to back-up WHP P1 revisit stations 
located between 166 deg. W and 143.5 deg. W.  But Kaiyo-maru cruise (P1W), 
which has planed to occupy stations in the west of 160 deg. W, could not 
occupy planned stations in the south of Hokkaido because of the temporal 
activity of the salmon fisheries there.  As the result, those stations not 
occupied by Kaiyo-maru were added to this cruise forming our duty to visit 
sixteen extra stations in the south of Hokkaido and twenty two stations 
between 166 deg. W and 143.5 deg. W.

We set sail on August 24, 1999 at Sekinehama, Japan. The first station of the 
cruise was located at 42.81 deg. N, 145.56 deg. E where the CTD+RMS 
observation began at 08:31 JST on August 25.  At the fourth station of P1_#7, 
we lost whole CTD+RMS system and LADCP system with CTD cable of 4000m long.  
As the back up CTD+RMS system did not work properly, we made a port at 
Hachinohe on August 27 for another new ROSETTE system and started the cruise 
again.  However, it was estimated that the preparation of new CTD+RMS system 
on the board would force us to spend more than 72 hours.  Then we gave up our 
duty off Hokkaido for the most important objective of the cruise, i.e. to 
occupy stations between Japanese efforts and Canadian efforts. P1_#74 located 
47 deg. N, 165.96 deg. W was set ahead. 

On the course to P1_#74, 47 XBTS and 47 XCTDs were casted by Hydrographic 
department of Japan Maritime Safety Agency.  We arrived at P1_#74 on 
September 3 1999 UTC. We occupied seventeen stations before we left the 
easternmost station of P1_#92 located at 46.99 deg N, 145.80 deg W on 
September 8.  Four SVP drifters were deployed in the center of the Alaskan 
Gyre and in the Alaskan stream on the way to Dutch Harbor.

The cruise experienced very rare but fatal accidents. But 2/3 of planned 
stations were occupied and 1/2 of planned water samplings were carried out.

We heartily hope that our data will be useful for studies on climate changes 
in the ocean.  Raw data including underway observations e.g. the multi-narrow 
beam and meteorology are kept in DMO of JAMSTEC, however, the ship board ADCP 
did not work properly.

    Hiroyuki Nakajima (Tokai University)
    Satoko Katsuyama  (Tokai University)
    Fujio Kobayashi   (Marine Work Japan)

(2) Objective
    Calibration of salinity measured by CTD.

(3) Measured Parameter
    Sample water salinity

(4) Instruments and Method
    The salinity analysis was carried out by a Guildline Autosal salinometer 
    model 8400B, which was modified by addition of an Ocean Science 
    International peristaltic-type sample intake pump.  Data of salinometer 
    was collected simultaneously by a personal computer.  A double 
    conductivity ratio was defined as a median of 15 readings of the 
    salinometer.  Data collection was started after 5 seconds and it took 
    about 5 seconds to collect 15 readings by a personal computer.

    The salinometer was operated in the air-conditioned ship's laboratory at 
    a bath temperature of 24 degree C.  An ambient temperature varied from 
    approximately 23 to 24 degree C.

      i) Standard Sea Water
         Autosal model 8400B was standardized only before sequence of 
         measurements by use of IAPSO Standard Seawater batch P135 whose 
         conductivity ratio was 0.99992.  After the standardization, 8400B 
         was monitored by SSW ampoule before and after the measurements for 
         samples of one station.  Total 23 ampoules of SSW were measured for 
         monitoring, whose standard deviation was 0.0004 psu.

     ii) Salinity Sample Collection
         The bottles in which the salinity samples are collected and stored 
         are 250ml clear glass bottles with inner caps and outer screw caps.  
         Each bottle were rinsed twice and filled with sample water.  
         Salinity samples were stored by the end of leg 1 in the same 
         laboratory as the salinity measurement was made.

    iii) Replicate Samples
         Replicate samples were drawn from several Niskin bottles for each  
         station.  Standard deviation in the measurements of replicate 
         samples was 0.0013 psu for 54 pairs.

     iv) Quality Flag
         Quality flag was made according to difference from corrected 
         salinity measured with CTD.  CTD salinity was corrected by linear 
         fitting with bottle salinity for pressure in the upper layer 
         (<1000db) and the deep layer (>1000db) at each station (see CTD).  
         For the bottle salinity exceeded double standard deviation, bad (4) 
         or doubt (3) flag was made.  Rms of residual difference was 0.001 
         between CTD salinity and good bottle salinity for deeper layer .

(2) Objective
    To describe changes in DO transect between 1985 and 1999.

(3) Measured Parameter
    Sample water dissolved oxygen

(4) Instruments and Method
    (a) Instruments and Apparatus
        Dispenser:  Eppendorf Comforpette 480/ 1000ml.
                    OPTIFIX/ 2ml
                    Metrohm Model 725 Multi Dosimat/ 20ml
        Titrator:   Metrohm Model 716 DMS Titrino / 10ml of titration vesswl
                    Pt electrode/ 6.0403.100(NC)
        Software:   Data acquisition / Metrohm, METRODATA / 606013/000 
                    Endpoint evaluation

    (b) Methods
        Samples were colleted from 12L Niskin bottles and a bucked for the 
        surface into the volumetrically calibrated dry grass bottles. At 
        least two times of bottle volumes of sample water were overflowed 
        before each sampling.  Sampling water temperatures for 4 or 5 bottles 
        were measured by a thermister- thermometer to calculate the change in 
        the volume of sampled water at the time of the titration. For other 
        samples of which temperature were not measured, potential 
        temperatures derived from CTD data were used. The sampling bottles 
        consist of ordinary BOD flask (ca. 180ml) and glass stopper with long 
        nipple inside which is modified from the nipple in Green and 
        Carritt(1966). Oxygen in the sample was fixed immediately after the 
        collection. Bottles were kept in a wooden box in the temperature-
        controlled laboratory until the titration.

        The analytical method and the preparation of regents were carried out 
        in the same way as described in WHP Operations and Methods 
        (Culberson, 1991). A 0.05N thiosulfateof titrant was adopted during 
        the cruise. Volumetric apparatus except titrator were calibrated 
        before the cruise. A titration was started about one hour after the 
        fixation of dissolved oxygen. Two sets of Metrohm titrators with the 
        automatic piston burette of 10ml and Pt electrode were used for the 
        titration in the temperature-controlled laboratory. The temperature 
        of samples which had been stored was 21 deg. C +/- 1 deg. C during 
        the cruise. The end point was determined by the potentiometric method 
        and evaluated by the second-derivative curve method. Concentration of 
        dissolved oxygen was computed using the equation in WHP Operation and 
        Methods (Culberson, 1991).


(5) Results
    We carried out 366 analyses of DO. Results are shown in .sea file.

    (a) Thiosulfate Standardization
        Thiosulfate regent was standardized when thiosulfate bottles of 
        titrator were empty.  Two kinds of 0.0100N KIO(3) standard solutions 
        were used for the standardization e.g. Lot 990420b(0.01003N) and Lot 
        990421(0.01002N).  The averaged volumes of thiosulfate for the 
        standardization were 1.969ml (titrator #1) and 1.973ml (titrator #2), 
        with standard diviation of 0.007ml and 0.001ml, respectively.

    (b) Pure water blank
        The blank value comes from the presence of redox species aparted from 
        oxygen in the regents, which behaves equivalently to oxygen to be 
        analysed.  The pure water blank or the titration blank was determined 
        using deionaized water (Milli-Q SP, Millipore) at each thiosulfate 
        standardization.  The average of pure water blanks was -0.015ml (#1) 
        and -0.015ml (#2) with standard deviation of 0.003ml and 0.004ml, 
        respectively.

    (c) Reproducibility
        In the cruise, replicate samples were drawn from some Niskin bottles 
        at each station to estimate the precision of the analysis.  85 pair 
        of replicate samples are analyzed to show the standard deviation (2 
        sigma) of 0.016ml/l or 0.2% of maximum value of DO concentration of 
        7.843ml/l in the cruise.

    Masahide Wakita    (Hokkaido University)

(2) Objectives
    Total dissolved inorganic carbon (DIC), titration Alkalinity (TA) and pH    
    are the main parameters of oceanic carbon cycle, which owes significant 
    importance recently for understanding of the fate of human-released CO2.  
    On the other hand, CFC11, CFC12, CFC113 and SF6 as chemical transient 
    tracers are very useful to clarify the water movement and/or the fate of 
    human-released CO2.  If we observed the above parameters simultaneously, 
    it will allow us to get more information about oceanic carbon cycle.

    Thus observing them together, and comparing the 1985 WOCE/WHP P01 data 
    with our data, we tried to get the time change of carbonate species and 
    water movement in the North Pacific subpolar region.  

(3) Sampling and Methods
    (a) DIC
        Method:    Extraction/Coulometry (Ono et al., 1998)
        Analyzer:  UIC CM5012 coulometer & KIMOTO EN-501 auto-coulometer
        Standard:  Primary standard grade Na2CO3  (Asahi grass Co.)
        Precision: +/- 2.7 μmol/kg

        Sub-samples were drawn into a 150 ml grass salinity bottle and closed 
        after 5 seconds of overflow. Duplicate samples were taken on every 
        station. All samples were stored under room temperature and analyzed 
        within 12 hours after the sampling followed by a coulometric method 
        (Ono et al., 1998). In some stations, measurement was also done by 
        the automatic DIC measurement system by coulometry (KIMOTO EN-501, 
        KIMOTO Electronic CO.).

        Two solutions of standard grade sodium carbonate were used as the 
        primary standard. Two concentrations of the seawater standards 
        containing a constant amount of DIC were made in laboratory as 
        working standard in the cruise. The DIC content of this working 
        standard was determined on board using the primary standard sodium 
        carbonate solutions. The Certified Reference materials distributed by 
        Scripps Institution of Oceanography was measured together with the 
        measurement at several stations.

    (b) TA
        Method:    Modified one-point method (Culberson et al., 1970)
        Analyzer:  Manual measurement
        Standard:  Primary standard grade Na2CO3 (Asahi grass Co.)
        Precision: +/- 3.5 μmol/kg

        Sub-samples were drawn into a 120 ml vial grass bottle.  Duplicate 
        samples were taken on every station.  All samples were stored under 
        room temperature and analyzed within 12 hours after the sampling 
        followed by the modified one-point titration method of Culberson et 
        al. (1970). 

        2l of 0.6N HCl solution was prepared and normality was calibrated 
        against the primary standard sodium carbonate solutions.  Calibration 
        of pH probe was made by Tris and 2-Aminopyridine Buffers (Dickson, 
        1993).  To correct the drift of glass electrode during the 
        measurement of pH after titration, we measure the pH of acidified 
        seawater which pH was controlled at 3.38 by adding HCl at interval of 
        every 10 samples. 

    (c) pH
        Method:    Continuous-flow Spectrophotometric pH measurements(Clayton   
                   et. al.,1993) (The pH indicator is m-cresol purple)
        Analyzer:  Spectrophotometer: Spectro multi channel photo detector 
                   MCPD-2000 (Otsuka ELECTRONICS CO.,LTD)
        Standard:  2-amino-2-hydroxymethyl-1,3-propanediol(tris)buffer in 
                   synthetic seawater, 2-aminopyridine buffer in synthetic 
                   seawater (Dickson, Goyet,DOE,1994 )
        Precision: +/- 0.002pH

        Sub-samples were drawn into a 120 ml grass bottle. Duplicate samples 
        were taken from surface water on every station. All samples were 
        stored under room temperature and analyzed within 12 hours after the 
        sampling followed by the modified Continuous-flow Spectrophotometric 
        pH measurements (Clayton et. al.,1993) 

    (d) CFC11, CFC12 & CFC113

        Method:    Purged and trapped ECD-GC method (Bulister and Weiss, 1988)
        Analyzer:  ECD-GC (Hitachi 263-30E)
        Standard:  Inter-calibrated gaseous bomb
        Precision: +/- 0.01 pmole/kg

        Sub-samples were drawn into a 120 ml grass syringe.  Duplicate 
        samples were taken on every station.  We used 30 ml as a sample.  All 
        samples were stored within 12 hours after the sampling followed by 
        the modified purged and trapped ECD-GC method (Bullister and Weiss, 
        1988).  We measured water sample of 30 ml. All data were normalized 
        to SIO '93 scale.

    (e) SF6
        Method:    Purged and trapped ECD-GC method (Law et al., 1994)
        Analyzer:  ECD-GC (Hitachi 5000A)
        Standard:  Inter-calibrated gaseous bomb
        Precision: +/- 0.03 fmole/kg
        
        Sub-samples were drawn into a 1200 ml grass bottle.  We used 500 ml 
        as a sample.  All samples were stored within 12 hours after the 
        sampling followed by the modified purged and trapped ECD-GC method 
        (Law et al., 1994).


(4)Preliminary results
   Measurements of DIC, TA , pH, CFC11, CFC12, CFC113 and SF6 were made with 
   the above precision.  This was the first result of the east-west cross 
   section where precise carbonate species and chemical transient tracers 
   were simultaneously observed in the North Pacific subpolar region.  We 
   will try to get the these detailed spatial distributions with the results 
   of SAGE-P1revisit first leg by R/V Kaiyo Maru of Japan Fisheires Agancy 
   during May-June 1999.  We also will do the time change of carbonate 
   species and water movement by comparing the 1985 WOCE/WHP P01 data with 
   our data in the future.

(2) Sample collection
    Sampling stations of 14C are planned to be every five degrees except the 
    western boundary area.  Samples were collected from depth using 12 liter 
    Niskin bottles.  Sampling glass bottles of c.a. 500ml  were baked at 450 
    degree C for tow hours after dipped into 1 N of HCl solution. After 
    baking, each bottle was capped with an aluminum foil until the sampling 
    on the ship board.  The seawater sample was siphoned into the glass 
    bottle with enough seawater to fill the glass.  Immediately after the 
    collection, about 10 ml of seawater was removed from the bottle and 
    poisoned by 1 ml of saturated HgCl2 solution.  The bottle was put a 
    screwed plastic cap on and sealed with butyl tape.  Then the bottle was 
    put in a wooden container.

    143 samples were collected from 7 stations.

(3) Sample measurement
    All samples were sent to Dr. Robert Key of Princeton University to be 
    analyzed.

            differences between the bath temperature and the instrument 
            temperature were checked at eleven temperature points of -1.4068, 
            1.0382, 4.5401, 8.1934, 11.6512, 15.1937, 18.6689, 22.1613, 
            25.6567. 29.1251 and 32.6239 ITS-90 degree C.

            The largest sensor drift during the period from the pre-cruise 
            calibration to the post-cruise calibration was found to be 
            +0.00009 deg C at 8.1934 deg C.  On the other hand, the absolute 
            temperature difference between the bath and the instrument 
            temperature was found to be largest as 0.00035 deg C also at 
            +8.1934 deg C using coefficients decided at the time of pre-
            cruise.  As the result the drift of the temperature sensor was 
            found to be +0.00021 of average with 0.00010 of standard 
            deviation.

            Consequently, if we define the accuracy of the sensor as the sum 
            of the drift and the absolute temperature difference at eleven 
            bath temperature, the result can be expressed as follows;

    (3)-2 Conductivity sensors
          Sensor 041723 was used during P1W five months ago. It was not 
          calibrated specially for this cruise.

    (3)-3 Pressure sensor
          Pressure sensor was calibrated in Aug 98, one year before the 
          cruise and on Jun. 00, a half a year after the cruise at Marine 
          Work Japan using the Bunden Burge weight tester. Calibration was 
          carried out on six pressure values from 14 psia to 10000 psia for 
          both case of the calibration. Any apparent hysteresis were found. 
          Coefficients were decided by linearly for pre- and post 
          calibrations. As the result, the intersect of 0 at the time of 
          newly equipped. Using the same coefficients, the slope value and 
          intersect value were found to be shifted to 1.00010 and +1.54 psi 
          or +1.0646 db.

          The linearity of calibration line was so good that the largest 
          offset of -0.12 db was found at around 2500 psi. 


    (3)-4 DO sensor
          DO sensor was not used.


(4) Data calibration
    (4)-1 Temperature
          Residual which was detected at post-cruise sensor calibration at 14 
          temperature points were so large and it is impossible to know the 
          history of the time drift.  So, we gave up to add any artificial 
          values to out put from CTD. 

    (4)-2 Salinity
          Bottle salinity values of which flags were 2 were used for the 
          salinity  calibration. Differences between CTD salinity and bottle 
          salinity were minimized using the least square method against the 
          pressure. Linear calibration equations were estimated for depths 
          shallower than 1000 db and deeper than 1000 db, respectively. The 
          calibration equation for deeper data was estimated first. The 
          calibration value at 1000 db was calculated and used as a fix point 
          for the calibration for shallower data. As the result, two 
          calibration equations which were connected to each other at 1000 db 
          were decided for every station. CTD salinity was re-produced using 
          these equations. Standard deviation from the bottle salinity at 
          each station is as follows;

          As for the traceability of SSW P-135 was -15/10000 psu to Mantyla's 
          value. Aoyama et al (2000) also reported -16/10000, -14/10000, -
          14/10000 for P135.  It must be noted that data calibration did not 
          include the traceability.

2004-04-10  Talley       SUM           Submitted
            Danie - Masao Fukasawa sent me a CDROM with the P1 occupation 
            from 1999. Here is a list of the cruises that make up the 
            section, which they called SAGE. (Part of the Subarctic Gyre 
            Experiment.)

            p1e - stations 92-115 R/V John Tully 6/2/99-6/10/99
            p1c - stations 4-92 R/V Mirai 8/25/99 - 9/8/99
            p1w - stations 1-74 R/V Kaiyo-Maru 5/23/99 - 6/11/99
            p1h - stations 4-13 R/V Mirai 9/30/99 - 10/2/99

            The files are called things like p1wsum.txt, p1csum.txt, 
            p1esum.txt, p1hsum.txt

            I don't have the data sets other than the sum files on my 
            computer, but will look for the CDROM when I get in. I gather 
            then that they weren't sent to the WHPO. 

2006-11-02  Johnson, G.  CTD/BTL/SUM   available on JAMESTEC website
            I note that P01 data are now in the public domain (see 
            http://www.jamstec.go.jp/iorgc/ocorp/data/p01rev_1999/index.html), 
            but are listed on the CCHDO site as with the PI (see 
            http://cchdo.ucsd.edu/data/tables/onetime/1tim_pac.htm#P01). 
            Would it be possible for these data to be served publicly on the 
            CCHDO site now? 

2006-11-06  Kappa        CTD/BTL/SUM   Website Updated
            Justin was able to get all the p01_1999 data online this morning. 
            Based on our time stamps, it looks like all the ctd files have 
            been worked by our data specialists. 2 of the hyd files have time 
            stamps, 2 don't. We'll be looking at them more closely in the 
            next couple weeks and will let you know if we find any anomalies.
