A.2  CRUISE SUMMARY

P02 was composed of four different cruises which were carried out during the 
period from October 14, 1993 to November 14, 1994 utilizing three different 
observation ships. No large volume sampling was carried out. Most of the 
observation line is located on 30N. But west of 134.5 E, the line goes 
northwest toward Cape Ashizuri along the PCM5 line. Also, east of 123W the line 
bends northeast to avoid Mexican territory.

Two of the four cruise were intended to get high-quality CTD data on high 
density observation stations.  For example, the shortest interval between 
stations is 30 nautical miles around some topographic features, with small 
volume water sampling for nutrient analysis (Salinity, Dissolved oxygen, 
Silicate, Phosphate, Nitrate, [Nitrite] and pH). These two cruises compose the 
central and eastern part of P02, and the western most part of P02, respectively. 
The first cruise began on 14 October 1993 and the latter began on the 15th 
of January, 1994. The third cruise was to get nutrient and chemical 
tracers data (Freon, Total Carbon, Tritium, Radioactive carbon/sampling only, 
pC02) mainly at 32 depths with CTD-ROSSETE 101 system. This cruise started on 
the 7th January, 1994.  The fourth and final cruise, which measured ctd data as 
well as discreet salinity and oxygen data, began on November 1, 1994.

Standards for nutrient is controlled by PIs among these three cruises. Standards 
used for these cruise were re-standardized at Scripps institution of 
Oceanography in the course of first cruise.

A.4. Scientific Goals

To get reliable dataset to estimate meridional transport of physical and 
chemical mass across  30N. Especially, at relatively shallow depths, the zonal 
transport of total carbon and CFCs included in NPIW-corresponding layer and 
NPSTMW are object to be estimated. Also heat and fresh water (and/or salinity) 
fluxes across 30N are subject to be estimated.

From 1991, WOCE-like observation programmes have been carried out along 32.5 N 
by the Hydrographic Department, Maritime Safety Agency and School of Marine 
Science, Tokai University. In these programmes current variations were checked 
by current meter moorings around the Shatsky Rise. Also, nutrient variations 
were examined through 5 different cruises. Results from these programmes show 
that eddies which are associated with the Shatsky Rise give so large effects on 
oceanic conditions around the region. The variation of nutrient profiles excess 
20% of their mean structure at the intermediate depth in magnitude.

In P02 cross section, we encounter three large topographic features, the Shatsky 
Rise, the Emperor Seamount and the Hess Rise. As explained in foregoing section, 
same P02 line will be repeated twice within three months. This strategy of 
operation will help us to know some standard errors in estimated fluxes through 
information about time-dependent oceanic structures.


A.5. CRUISE TRACK AND STATIONS

P2 line, along 30N in the North Pacific, consists of four cruises and includes 
178 stations.  P02E occupied the stations from 155 5'E to eastern boundary of 
the Pacific.

A total of 131 CTD/rosette stations were occupied using a GO 24 bottle rossete 
sampler with 23 1.2-liter Niskin bottles, and a NBIS Mk IIIB CTD equipped with 
Benthos altimeter.

SAMPLING 
The water sample measurement were made for salinity, oxygen,
phosphate, silicate and nitrate+nitrite.  The sampling depths in db
were 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1250, 1500,

C  HYDROGRAPHIC MEASUREMENT TECHNIQUES AND CALIBRATIONS

C.1 SAMPLE WATER SALINITY MEASUREMENTS
    (H. Yoritaka)
    November 1996

SALINITY SAMPLE COLLECTION 
The bottles in which the salinity samples are collected and stored are 125 ml 
brown glass bottles with rubber plugs. Each bottles were rinsed three times and 
filled with sample water. Salinity samples were stored for about 24 hours in the 
same laboratory as the salinity measurement was made.

INSTRUMENTS AND METHOD 
The salinity analysis was carried out by a Guildline Autosal salinometer model 
8400A. After three times rinse with sample water, double conductivity ratio were 
measured at fourth and fifth time. If difference between fourth time and fifth 
time was more than 0.00003 in double ratio, one more measurement was carried out 
at sixth time. The salinometer was operated in the air-conditioned ship's 
laboratory at a bath temperature of 24 deg. C. An ambient temperature varied 
from approximately 22 to 24 deg. C., and repeated rapid lowering and slow 
rising.

STANDARD SEA WATER 
Autosal model 8400A was standardized only before sequence of measurements for 
each leg, using IAPSO Standard Seawater batch P123. After the standardization, 
8400A was monitored with SSW ampoules at every two stations. There was drift in 
monitoring of SSW, so correction was carried out for sample measurements as 
follows:

Leg 1
Station 035-066: Corrected Double Ratio = Measured Double Ratio -0.00005
Station 067-096: Corrected Double Ratio = Measured Double Ratio +0.00008

Leg 2
Station 097-107: Corrected Double Ratio = Measured Double Ratio -0.00000
Station 108-145: Corrected Double Ratio = Measured Double Ratio +0.00012
Station 146-165: Corrected Double Ratio = Measured Double Ratio -0.00002

Duplicate and Replicate Samples Duplicate samples were drawn in the deeper 
layers in case of shallower water depth than 5000 m. Replicate samples were 
drawn from three or four Niskin bottles in every station. Standard deviation in 
the measurements of duplicate and replicate samples were as follows:

        Duplicate       All             0.0023 psu      126 pairs
                        >=3000 db       0.0017 psu      81 pairs
        Replicate                       0.0014 psu      465 pairs.

C.2  CTD Measurements
     (Hiroyuki Yoritaka)
     November 1996

EQUIPMENT, CALIBRATIONS AND STANDARDS

1. Neil Brown Mk.IIIB CTD with FSI titanium pressure sensor, Beckman
   oxygen sensor and Benthos altimeter. Identification S/N 1194 and 1216.
2. General Oceanics 1.2 liter 24 bottle rosette sampler.  
3. Eight sets of SIS digital reversing thermometers and digital reversing 
   pressure meters.

The shipboard equipment included the following major units:

1. EG&G deck unit data terminal. Model 1401.
2. NEC PC-9801DA.
3. GO rosette firing module.

The data was backed up in DAT cassette data recorder.

Laboratory calibration of the Mk.IIIB CTD temperature and pressure sensors was 
carried out as follows;

                Pre-Cruise                      Post-Cruise

#1216   SEA Co. (October 1993)          SEA Co. (January 1994)

According to the pre-calibration dataset (Table 3.1), temperature was
corrected by following equation.

            Tcorrected=Traw+a0+a1*Traw+a2*Traw^2+a3*Traw^3+a4*Traw^4

From the pre- and post-cruise temperature calibrations, temperature sensor 
errors during the cruise are estimated to be within 0.001C for 0-8C, within 
0.002C for >8C on #1216. On #1194, there were 0.004C differences between pre- 
and post-cruise calibrations. Differences in temperature between CTD and digital 
reversing thermometer of the deepest layer over the cruise showed #01-1194 was 
0.002C lower in temperature than #01-1216. It was consistent with pre-cruise 
calibration. Only one titanium pressure sensor (S/N 1333) was used over the 
cruise, while CTD was changed. According to the pre-calibration dataset (Table 
3.3), pressure was also corrected by following equation.

         Pcorrected=Praw+a0+a1*Praw+a2*Praw^2+a3*Praw^3+a4*Praw^4-Pdeck

                               a0:     0.039722
                               a1:    -0.0017326
                               a2:     4.6731E-07
                               a3:    -6.5441E-11
                               a4:     3.5102E-15

In the six times down/up calibration (up to 1000, 2000, 3000, 4000, 5000, 6000 
db), there were differences between down-cast and up-cast within 0.5 db, so 
pressure at up-cast was corrected by equation same as down-cast.

during the cruise are estimated to be 2.6 dbar at 6000 dbar depth.

EQUIPMENT PERFORMANCE

CTD
Both oxygen sensors on #1194 and #1216 were out of condition. So we change CTD 
twice for maintenance of oxygen sensor, after station 041 and 74. But they did 
not recovered. At station 156, data from CTD #1194 included noise, so we change 
CTD for #1216. Summary of employment for CTD is as follows;

                             Station 035-041: #1194
                             Station 042-074: #1216
                             Station 075-156: #1194
                             Station 157-165: #1216
                                 
Another external sensors, pressure sensor and altimeter were in good
condition.

C.3  CTD DATA PROCESSING

The data processing procedure was as follows:
(1) Noise removal
(2) P and T data correction by laboratory calibration
(3) Time lag filtration for T data for adjusting to C sensor response
(4) C data correction for sensor modification
(5) Time lag filtration for P and C data for adjusting to T sensor response
(6) Pressure averaging
(7) C data correction by water sampling data
(8) Pressure centering

(1) Noise removal Firstly, we perform first difference check in which
    if a data value jumps more than a certain critical value, the data was
    marked and interpolated. The critical values are 1.0 dbar in pressure,
    0.02 degree in temperature and 0.02 mmho/cm in conductivity.

(2) P and T data correction by laboratory calibration Pressure and
    temperature correction by laboratory calibration were carried out as
    mentioned in session 3.2.

(3) Time lag filtration for T data for adjusting to C sensor response
    From lowering speed of CTD, T data was filtered for adjusting to C
    sensor response as follows;

      Tfiltered(t)=exp(-dt/tauc)*Tfiltered(t-dt)+(1-exp(-dt/tauc))*Traw(t)

where dt means CTD sampling interval (1/25 sec.), tauc means response
time of C sensor.  Response time of C sensor was read from Giles and
McDougall (1986), the method was following Kawabe and Kawasaki (1993).

(4) C data correction for sensor modification According to SCOR Working
    Group (1988), C data was corrected for alumina sensor as follows;

             Ccorrected=Craw*(1-6.5E-06*(T-2.8)+1.5E-08*(P-3000))

(5) Time lag filtration for P and C data for adjusting to T sensor
    response P and C data was filtered for adjusting to T sensor response
    as follows;

       Pfiltered(t)=exp(-dt/tau)*Pfiltered(t-dt)+(1-exp(-dt/tau))*Praw(t)
       Cfiltered(t)=exp(-dt/tau)*Cfiltered(t-dt)+(1-exp(-dt/tau))*Craw(t)

where dt means CTD sampling interval (1/25 sec.), tau means response time of T 
sensor. Response time of T sensor was estimated from maximum lagged correlation 
between T data series and C data series as follows;

#1194: 8/25 sec. (320 msec)
#1216: 5/25 sec. (200 msec)

(6) Pressure averaging P, T and C data were removed at upward moving at down-
    cast, and were averaged over (+/-)1 dbar range.

(7) C data correction by water sampling data Conductivity data was calibrated by 
    comparison with sample salinity. We compared all CTD conductivity data 
    averaged over 64 data (2.56 seconds) with those of water samples which was 
    converted from salinity with temperature and pressure at the points bottles 
    closed just after collection of 64 CTD data. We fitted a linear regression 
    equation of

                              Csample = a0+a1*Cctd

with minimizing RMS. error. The water sample data whose values are most 
different from Cctd are rejected. This rejection and fitting procedure is 
repeated until all data are within 0.003 mmho/cm. By using the CTD salinity 
determined with the cell factors determined by the above procedure, we again 
compared the CTD salinity and sample salinity. In this process, we detected 
bottle leak, miss-fire bottles and bottles taken at different depth. With the 
information of bottle rearrangements and rejection of questionable sample data, 
we again determined the cell factor as

             Station 035-041(#1194): a0=-0.020073    a1=1.0007220
             Station 042-074(#1216): a0=+0.010755    a1=0.9998601
             Station 075-096(#1194): a0=-0.022169    a1=1.0007604
             Station 097-156(#1194): a0=-0.016253    a1=1.0005141
             Station 157-165(#1216): a0=+0.004395    a1=1.0000042

With the cell factor determined by the above procedure, mean difference between 
CTD and water sample and standard deviations for depth ranges in the deep part 
are in the Table 3.5,

04/13/99  Talley      SUM          Data Update  see note:
          Steve - I placed corrected versions of p02csu.txt and p02esu.txt
          in my ftp area at whpo.  Please replace the online versions with
          these (and acknowledge).  (What did I change - replaced
          P02C in the P02E file with P02E,  replaced P02W in the P02C
          file with P02C).  Lynne
          
04/14/99  Talley      CTD          Data Update  see note:
          station 119 on p2e was corrupted.  It was sent in a 1 dbar series, 
          unlike all of the other stations.  I decimated it to 2 dbar, changed 
          the number of records in the header to match the 2 dbar series, and 
          ftped it to the whpo site.  
          
04/15/99  Bartolacci  SUM          Data Update  see note:
          I've replaced all of the p02.sum files (p02w, p02e, p02c) and updated 
          the table to reflect this. In the case of p02c and p02e the sum file 
          changes (via Lynne)were correcting the occurrances of the old line 
          number designation with the new line number designation, and (by 
          me) replacing the slashes in the expocode to underscores. (See Lynne's 
          emails below)

          IN the case of p02w the .sum file changes made (by Lynne) were 
          converting decimal degrees into degrees and minutes in the lats and 
          lons; the time was converted to GMT; station no. now has place holding 
          zeros; cast type was changed from CTD to ROS; and height above bottom, 
          wire out, and no. of bottles columns were also added. This conversion 
          has shifted columns, however I ran sumchk on it with no errors. 
          Slashes in the expocode were also replaced by underscores.

          I have also replaced the corrupted P2E119.WCT file with Lynne's 
          updated version, and updated the table to reflect this. The table was 
          also corrected to reflect the *bottle* data file being encrypted, NOT 
          the .sum file (previously the table indicated the .sum file was Non-
          public and the bottle file was public).
          
09/19/00  Michida     BTL          Data Update
          With regard to the hydrographic data collected by Japanese groups, I 
          found that the present status of availability of the data for P02E and 
          P02W appeared as 'NP' in the listings of WHPO web site. I believe they 
          should be ready to be made public.   Have you had any contact to or 
          from Mr Yoritaka, the present contact person for both lines? I will be 
          pleased to ask him to confirm that the data are to be public, if 
          necessary.
          
10/02/00  Fukasawa    NUTs/CFCs    Data Update
          NUTs sent to WHOI, CFCs not collected  As for P2C and E, nutrients 
          data were collected and Dr. Saito, who is the PI, reported me that 
          data was submitted to WHOI. PI of CFCs is Dr. Watanabe although CFC 
          data were note collected on neither P2C nor P2E.
          
02/21/01  Diggs       NUTs         Submitted silcat, no2 no3, phspht
          I received P02C/E nutrients as well from Saito, and just reformatted 
          them and placed them in the original directories for each line.  I'll 
          have Stacy merge them in.
          
03/09/01  Yoritaka    CTD/BTL      Data are Public
          database updated as requested, see note:
          I would like to consent to open Bottle_S/O2 and CTD data on P2E and 
          P2W to the public as PI.  Then, would you please change some 
          information on the summarized table of WHP one time cruises on web as 
          follows:
                    P02E;
                    CS: Bando/JODC -> Bando/(HD)MSA
                    Ship: SYOYO -> SHOYO
          
04/03/01  Bartolacci  BTL          Website Updated
          Files Unencrypted except NUTs; See note:
          I have unencrypted the bottle file for both legs of this cruise, 
          however the nutrients still reside in the original directory and are 
          not yet merged into the bottle file.


          Sarilee, Could you possibly merge these nutrients into the on-line 
          bottle file? They're in the 'original' directory for P02E.

04/03/01  Saito       NUTs         Data are Public
          I heard from Yoritaka-san that P2E nutrient data have not yet public, 
          then I would agree with these data will be public.
          
04/04/01  Michida     NUTs         Data are Public
          Today I heard that Dr. Saito, the PI for nutrient data of P2, sent an 
          email to someone concerned in SIO (Lynne Talley? ) to make the data 
          public.    I hope things go well in this regard. 
                    
07/17/01  Diggs       BTL/SUM      Website Updated  new P02e files on-line
          SUM file reformatted  SUM, Bottle: (silcat, no2 no3, phspht)
          I have put all of the new P02e files on-line (with nutrients) at Lynne 
          Talley's request. I have also attached Sarilee's reformatting note 
          (kinda long). Sarilee also reformatted the SUM file and I have put it 
          out on the website as well.
                              
12/03/01  Diggs       CTD/BTL      Website Updated  CSV File Added, see note:  
          BOTTLE  converted to exchange format and placed files online. 
          CTD still non-public?
                    
12/06/01  Diggs       CTD/BTL/SUM  Website Updated
          Files reformatted and online, see note:  I have put all of the new 
          P02e files on-line (with nutrients).  I have attached Sarilee's 
          reformatting note (kinda long).  Sarilee also reformatted the SUM file 
          and put it out on the website as well.

          thanks,

          Merged the nutrients into the .sea files for P02E.

          The nutrient file had two sta. 35.  When I compared the pressures of 
          the second sta. 35 in the nutrient file with the pressures for sta. 36 
          in the .sea it was obvious that the station designation in the 
          nutrient file should have been 36.

          Ditto above only for sta. 105.  Should have been 106 in the nutrient 
          file.

          There were numerous levels throughout the file that had 0 as the 
          sample and/or bottle number.  These levels had no data and were not in 
          the .sea file and were not merged into the .sea file.

          Stas. 36 and 37 had at 5501.1 and 5500.5 respectively a value of 
          972.51 for SILCAT and 9.73 for PHSPHT.  The QUALT1 flag was 9 for each 
          of them.  These are impossible values for these parameters so I 
          changed the values to -9.00.

          Sta. 40 at 1000.0db had 99 for QUALT1 flags but a value of 113.91 for 
          SILCAT and 9.73 for PHSPHT.  Changed PHSPHT value to -9.00, SILCAT 
          value is reasonable.  Changed QUALT1 flags to 39.

          List of stations where QUALT1 flags were not consistent with the data.  
          I changed them so they agree with the data.

          NOTE - most of the QUALT1 flags in the nutrient file were 3, so I used 
          3 when changing Q1 codes, except in one case where the data were 
          obviously bad.
