I. CRUISE NARRATIVE

Tomowo Watanabe (National Research Institute of Far Seas Fisheries 
                 Laboratory) 

The cruise was the first cruise of the R/V Kaiyo-Maru of Japan Fisheries 
Agency in 1999 fiscal year and was planned to cover the western stations of 
the WHP-P1 revisit observation, which was a part of SAGE (Sub-Arctic Gyre 
Experiment). The purpose of the P1-revisit cruise was to detect the decadal 
change of the oceanographic structure from P1 cruise in 1985. 

We departed from the Harumi pier of the Tokyo harbor at 13:46 JST on May 21, 
1999. On the way to the first station of the WHP-P1 revisit, we did the 
CTD+RMS observation at 38.94N, 144.09E on May 22 for checking the conditions 
of equipments, and where we confirmed the techniques for water sampling from 
the Niskin bottles. The first station, P1_#1, was located at 42.98N, 145.45E 
where CTD+RMS observation began at 10:09 JST on May 23. After finishing the 
first observation, we sailed to southeastward along the original P1 
observation line. In the daytime of the same day, we could occupied to the 
forth station. In the nighttime we found the many drifting nets of salmon 
fisheries in the course and we decided to skip 15 stations from the next. 
Taking the bypass route, we reached at the southernmost station P1_#20 
located 39.69N, 147.93E, and where we restarted the P1-revisit observation. 
15 CTD+RMS stations (P1_#20 - #37) and 3 XCTD stations (#21, #23, #25) were 
occupied along the P1 line off the Kurile Islands. The LADCP was changed at 
P01_#34. At P1_#35, a jellyfish entered the CTD sensor and brought the bad 
influence to the CTD data. Since we had to save the ship time, the second 
cast was not done. We reached to 47N at P01_#38 located 47.00N, 160.00E on 
May 28 and continued the P1 revisit cruises eastward along the 47N latitude 
line. The stations along the 47N line were basically the same to the original 
stations of P1 observation in 1985. We added the cross points with X13 and 
X14. The XCTD observations were also done at between CTD+RMS stations and 36 
probes were launched. The CTD+RMS observation was favorable in general. 
Though we experienced the wire trouble at P01_#56 and the CTD sensor troubles 
at P01_#58, both troubles were fixed for short time and successfully 
recovered by the second cast. 34 CTD+RMS stations were occupied along the 47N 
line from P01_#38 to P01_#74 which was the easternmost station of the R/V 
Kaiyo-maru cruise located 47.00N, 165.97W. 

After finishing the CTD+RMS observation at P01_#74 on June 7, we changed the 
course and started to the west to reoccupy the station P01_#35. We did 75 XBT 
observations on the course from 166W to 157E every 0.5-degree longitude by 
the request of the hydrographic division of Japan Meteorological Agency on 
SAGE. We left the last station CTD-RMS station P01_#35 at 12:00 JST June 11 
and we turned the bow to Kushiro. We arrived in the Kushiro harbor on June 
13. 

The cruise succeeded to take oceanographic data with high accuracy by 
cooperation of many people. We believe that our dataset are valuable and 
effectively used for the climate study.

III. SAMPLE WATER SALINITY MEASUREMENTS

(1) PERSONAL

Ayako Nishina   (Kagoshima University) 
Tomowo Watanabe (Fisheries Agency) 
Masao Fukasawa  (Tokai University) 


(2) OBJECTIVES

Calibration of salinity measured by CTD. 


(3) MEASURED PARAMETER

Sample water salinity 


(4) INSTRUMENTS AND METHOD

The salinity analysis was carried out by two Guildline Autosal salinometers 
model 8400B, which were modified by addition of an Ocean Science 
International peristaltic-type sample intake pump. One salinometer was 
operated in an air-conditioned ship's laboratory and in a laboratory of Far 
Fisheries Laboratory JFA. The other one was operated also in an air-
conditioned room at Kagoshima University. 

i) Standard Sea Water 

All salinometers were standardized using IAPSO Standard Seawater batch P133. 
Aspirated sea water was applied every salinometer at least for a full day, 
then each salinometer was standardized. Drifts of a salinometer were examined 
by SSW of P133 ampoule before and after the measurements for samples of one 
station. Drifts of all salinometer was so small that no re-standardization 
was needed. 

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 was 
rinsed three times and filled with sample water. Salinity samples were stored 
in the same laboratory where the salinity measurement was made at least for 
50 hours. 


iii) Replicate Samples 

Replicate samples were drawn from several Niskin bottles for each station. 
Standard deviation in the measurements of replicate samples was 0.0011 psu 
for 208 pairs of which flags were not 4. 



IV. SAMPLE DISSOLVED OXYGEN MEASUREMENTS

(1) PERSONEL

Ayako Nishina     (Kagoshima University) 
Hiroyuki Nakajima (Tokai University) 
Masao Fukasawa    (Tokai University) 


(2) OBJECTIVE

To describe changes in DO transect between 1985 and 1999. 


(3) Equipment and techniques 

Bottle oxygen samples were taken in calibrated clear glass bottle of 100 ml 
capacity before other samples were drawn. To check and to allow corrections 
for change in capacity of the sample between the closure of the rosette 
bottle and fixing of the dissolved oxygen, the potential temperature 
calculated from CTD results was used after a correction based on the measured 
temperature data. Analysis followed the whole bottle method. The thiosulfate 
titration was carried out in a controlled environmental laboratory maintained 
at temperature between 20 deg.C and 28 deg.C. The normality of thiosulfate was 
set to be 0.05 when the regents were made up, and checked their changes 7 
times during a cruise. Replicate samples were taken from bottles of fixed 
number (2, 7, 12, 17, 22) on every cast ; usually these were included deepest 
bottle and DO minimum bottle. 

The end point of titration was determined by a photometric method using ART-
3/DO-1 manufactured by HIRAMA (Japan) which has an auto burette with 6 ml 
cylinder. Titration volume was always smaller than 3.5 ml and the smallest 
increment from the burette was 2.5 micro-liters. 

The volume of oxygen dissolved in the water was converted to mass fraction by 
use of the factor 44.66 and an appropriate value of the density; corrections 
for the volume of oxygen added with reagents and for impurities in the 
manganese chloride were also made as described in the WOCE Manual of 
Operation and Methods (Culberson, 1991, WHPO 91-1). 


(4) REPRODUCIBILITY OF MEASREMENT

During the cruise 1481 samples were taken including 167 of replicates. 
Statistics on the replicates are given in Table 1. These include both 
replicates and those taken from different bottles fired at the same depth but 
exclude bad measurement data.

(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 CO(2). On 
the other hand, CFC11, CFC12, CFC113 and SF(6) 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 Na(2)CO(3) (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 Na(2(CO(3) (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 on every station.  Despite 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 (Bullister 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) SF(6) 

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 SF(6) 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 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.

Robert Key     (Princeton University): analyzing sample 


(2) OBJECTIVE

To add new data to the historical P1 database and to estimate the ocean up-
take rate of the anthropogenic carbon together with the CFCs data. 


(3) 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 shipboard. 
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 HgCl(2) 
solution. The bottle was put a screwed plastic cap on and sealed with butyl 
tape. Then the bottle was put in a wooden container. 

295 samples were collected from 12 stations. 


(4) SAMPLE MEASUREMENTS

All samples were sent to Dr. Robert Key of Princeton University to be 
analyzed.

(4) SENSOR CALIBRATION

(4)-1 Temperature sensor 

Temperature sensor was calibrated before and after the cruise on 3 Apr. 99 
and 29 Jun. 99, respectively at Sea-Bird Electronics. Post-cruise residuals 
defined as differences between the bath temperature and the instrument 
temperature were checked at eleven temperature points of -1.4108, 1.0995, 
4.5914, 8.1890, 11.6230, 15.1795, 18.6833, 22.1824, 25.7416, 29.1567 and 
32.6894 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 0.00003 
deg C at around 1.0995 deg C. On the other hand, the absolute temperature 
difference between the bath and the instrument temperature was found to be 
largest as 0.0007deg C at around 15.1770 deg C using coefficients decided at 
the time of pre-cruise. 

Consequently, if 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;

It must be noted that these numbers shows the accuracy of the CTD temperature 
measurement at its worst case. 

(4)-2 Conductivity sensors 

Sensor 042256 was used before the stations 54. At station 54 the sensor was 
replaced with 041723. Sensor of 041723 was calibrated at Sea-Bird Electronics 
on 6 Apr. 99 and 29 Jun. 99 just before and after the cruise. The sensor of 
042256 was calibrated on 3 Apr. 99 and 29 Jun. 99 just before and after the 
cruise. For both of sensors, no severe non-linear response was detected which 
may affect the in-situ calibration of CTD salinity using the bottle salinity.

(4)-3 Pressure sensor 

Pressure sensor was calibrated at the time of the purchase in May 96 and 
after this cruise on 7 Jul. 99. Calibration was carried out on six pressure 
values from 14 psia to 10000 psia. Any apparent hysteresis was found. 
Coefficients were decided so as to make the real pressure value and the CTD 
out put value are linear with the slope of 1 and the inter-sect of 0 at the 
time of newly equipped. Using the same coefficients, the slope value and 
intersect value were found to be shifted to 1.00003 and -1.38 psi or -0.954 
db. 

The linearity of calibration line was so good that the largest offset of 
-0.23 db was found at around 2000 psi. 

(4)-4 DO sensor 

DO sensor was calibrated on 7 Jul. 1999 after the cruise. Before the cruise, 
the sensor was calibrated on 17 Dec. 1997. Though changes in coefficient 
values were large, the response of the sensor was good enough for post-cruise 
calibration using results of the titration of bottle water. 


(5) DATA CALIBRATION

(5)-1 Temperature 

Residual which was detected at post-cruise sensor calibration at 14 
temperature points were interpolated and added to the CTD out put. The larges 
value of 0.00007deg.C was added to the CTD out put of 1.0995 IPTS-68. 

(5)-2 Salinity 

Bottle salinity values of which flags were 2 were used for the salinity 
calibration. Differences between CTD salinity and bottle salinity were 
minimumized using the least square method against the pressure. Linear 
calibration equations were estimated for depths shallower than 1000db and 
deeper than 1000db, respectively. The calibration equation for deeper data 
was estimated first. The calibration value at 1000db 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 1000db 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-133, was -14/10000 psu to Mantyla's value. 
Aoyama et al. (2002) also reported -17/10000, -14/10000, -12/10000 for P133. 
It must be noted that data calibration did not include the traceability. 

(5)-3 Pressure 

CTD outputs were re-produced using coefficients noted above. 

(5)-4 Oxygen 

Not yet. There seems to be a systematic error between bottle DO data of 
Kaiyo-maru cruise and Mirai cruise which can be attributed to the different 
analyzing method. Preliminary results of data calibration are crosschecked 
now.




CCHDO DATA PROCESSING NOTES

Date        Contact      Data Type     Action
----------  -----------  ------------  ------------------------------------
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.
