2a.) Cruise Track: The station locations are shown in Fig.1 and listed in
Appendix 1 and in the P13.sum file.
The P13 section began at 54 14.7 N, 161 06.6 E and moved southeastward to 
51 30 N 165 E.  The section then proceeded southward to 4 44.9 S 164 00.2 E.
Nominal station spacing north of 36 N was 30 nautical miles.  Because of 
ship malfunctions and delays, insufficent time was available to complete the 
section as planned, and station spacing increased south of 30 N (see discussion below).
  
2b.) 87 Stations/CTD casts were completed, including 4 on the transit
Leg 0, 51 on Leg 1 and 22 on Leg 2.
Only small volume (10 liter and 2.4 liter) sample bottles were used. 
A breakdown of parameters sampled is given in the P13.sea and P13.sum files 

2c.) Floats and drifters deployed:
17 RAFOS floats and 1 RAFOS sound source were deployed.
11 ALACE floats were deployed. 
17 ADCP profiles were obtained at stations betwen 4 N - 4 S using a
    rosette mounted lowered ADCP instrument.

Approximately number of water samples analysed:
    2685 salinity 
    2572 oxygen
    2608 nutrients
    1728 chlorofluorocarbons (CFCs)
    1270 Total CO2
    1265 Alkalinity

Approximate number of water samples collected for shore-based analysis:
     761 helium-3 
     296 tritium
     778 AMS radiocarbon (C-14) and C-13
 
Continous underway ADCP measurements were made along the cruise track.
Measurents of surface-layer dissolved gases and atmospheric trace gases 
   (including nitrous oxide and halocarbons) were made along the entire
    ship-track. 
Air samples were collected at approximately 5 degrees intervals for
   isotopic analysis of carbon monoxide and methane.
 
Fig. 2 shows the locations where water samples were collected for
    analysis of dissolved oxygen and  nutrients.  CFCs, TCO2, alkalinity,
    radiocarbon, C-13, helium-3 and tritium were collected at subsets
    of these locations (see .sea file for sample locations for each parameter).

4.) Scientific Program and Methods:
 
Leg 0:
    Leg 0 of the CGC92 expedition consisted of a transit from Los Angeles
to Dutch Harbor, with 4 stations occupied along the cruise track to
test the CTD/rosette system.  One of these stations was a re-occupation
of Station 'P' (50 N, 145 W).   SIO scientists tested an underway ADCP
system along the cruise track.


Leg 1:
    Leg 1 consisted of 51 stations (Sta. 5-55).  The first station on this
leg (Station 5) was a test CTD/rosette cast made in the Bering Sea,
along the transit from Dutch Harbor to the start of the P13 line near
the Kamchatka Peninsula.  Sampling of the P13 section began on 21
August 1992 near the 200 meter isobath off Kamchatka.  A series of
stations were occupied on a southeastward transit down the continental
slope and across the Kamchatka Trench.  The section turned directly
southward at about 51 30 N, 165 E, and continued along the 165 E
meridian for the remainder of Leg 1.  A RAFOS sound source was deployed
at 31 N, 165 E.
    Nominal station spacing was 30 nautical miles from the start of the
section to about 40 N.  Due to a series of delays during the first part
of Leg 1 (see discussion below) a decision was made at about 36 N to
stretch nominal station spacing for the remainder of Leg 1 (36 N - 10 N)
to 40 nautical miles.
    Due to concerns about possible structural deformation to Vickers, and
concern over failure of a water-tight door to close properly, work on
the P13 CTD/rosette section was halted on 9 September 1992 at about 30
N, and Vickers was ordered to steam directly to Kwajalein.  We were
unable to occupy any stations along the emergency transit to
Kwajalein.

A total of 17 RAFOS floats and 2 ALACE floats were deployed during Leg 1.
 

Leg 2.  
    Vickers remained at the dock in Kwajalein for an extended period of time
for evaluation of structural integrity by two marine architects and for
repair. Vickers left Kwajalein on 26 September 1992 and began steaming
back to the break-off point to continue work on the P13 section.
    Contact was made with TOGA-COARE investigators (the group scheduled to
use Vickers following the completion of the P13 section) to negotiate an
extension for Leg 2, which would allow us a reasonable chance to
complete the P13 section.  After direct negotiations with TOGA-COARE
investigators over the revised Vickers schedule, we were unable to come
up with a mutually satisfactory agreement.  The position held by
TOGA-COARE at the end of these negotiations (requiring Vickers to be
in port in Noumea on 21 October 1992) did not allow us enough time to
complete the WOCE P13 section to even minimum WHP specifications.
Since an agreement could not be reached between the 2 programs, the
final decison was made by the Director of NOAA's Office of Global
Programs, who sent instructions to USC that Vickers should
arrive in Noumea on 21 October for TOGA-COARE staging.
 
    With the remaining allocated time, Vickers occupied CTD/rosette
stations at a nominal spacing of about 2 degrees from 28 N to 4 N, and
closer spacing from 4 N to 4 30"S.  Lowered ADCP measurements were made on
stations between 4 N and 4 S.  The section was terminated on 17 October
1992 at 4 45 S 164 0 E in order to arrive in Noumea by the 21 October
deadline.  A total of 32 stations (Sta 56-88) were occupied during Leg
2 (one station- Sta. 60 was aborted and not included in the listings).
    A total of 9 ALACE floats were deployed during Leg 2. 

Discussion:

   A NOAA-PMEL designed 36 position, 10-liter rosette frame was used at
84 of the 88 stations on the expediton.  A smaller 12-position, 2.4
liter rosette was used as a bad-weather backup system at several
stations during the cruise.  A General Oceanics (GO) 36 'Intelligent'
underwater array (pylon) and deck unit were used with the PMEL 36
position system, along with a Neil Brown MARK III CTD (NBIS serial #
1111).
   We feel that the new 36 position PMEL rosette package performed well
on this expediton.  The newly-designed General Oceanics 36 position
'Intelligent' underwater array also performed relatively well. The GO
system provides real-time information on the position of the release
lever, and allows bottles to be closed in any order desired.  Although
a bottle (or two) often failed to close properly during casts due to
'sticky' release pins on the GO underwater array, these problems could
normally be diagnosed immediately from information sent from the
underwater array to the deck unit.  This information gave the CTD
operator the option of choosing to release another bottle at that depth
if desired.  Overall, the success rate acheived for closing 10-liter
bottles with this new system was about 95%. 

   

5.) Major Problems and Goals not Achieved
    We encountered a number of problems which led to delays while at sea,
and longer-than-planned port stops.  Delays were encountered leaving
port in Los Angeles (1.5 days), during an emergency port stop in Port
Huaneme, CA (1 day), and extended port stops in Dutch Harbor (2 days)
and Kwajalein (8 days).  Time was lost due to slowdowns along the
cruise track because of ship mechanical problems and weather.
Additional time was lost on station due to conducting cable and wire
termination problems.
     There were problems with logging bottom depth using the shipboard PDR
system.  At several stations (28, 48, 53, 61) no reliable PDR bottom
return could be obtained during the casts, and UNC values for these
stations are not shown in the P13.sum file.  Estimates of UNC bottom
depths for these stations, (for use in showing bottom bathymetry, eg as
shown in Fig. 2) were made by interpolation to adjacent stations,  At a
number of other stations, the PDR signal was too weak to be reliably
deteced upon the approach of the rosette near the bottom, causing such
casts to be stopped a hundred meters or more away from the sea bottom
for safety purposes.

    A substantial amount of time was lost (8-10 days) due to the emergency
breakoff of the section at 30 N, and the need to return to this point
to continue the section on Leg 2.  The decision that Vickers would be
dropped off in Noumea for the first phase of COARE staging (rather than
a port closer to the end point of the abbreviated CTD section, eg
Honiara) cost additional ship and station time.


  Due to this series of delays, the expedition extended about 19 days
past the originally scheduled completion date of 3 October 1992 in Noumea,
yet a substantial number of planned stations were not occupied.  
     We feel that the station spacing acheived along the segment north of 30
N and the section near the equator (4 N- 4 S) met WHP guidelines, and
that under normal circumstances, the full P13 section would have been
completed successfully during this expedition.  Preliminary analysis of
the data indicate that they meet WHP quality quidelines for precision
and accuracy. For several chemical tracers (eg. radiocarbon,
helium-tritium, CO2), the total number of samples obtained, and the
average horizontal and vertical sample spacing north of 4 S is
reasonably close to that originally planned for the expedition (see
P13.sea file)

   We are disappointed with the overall outcome of the expedition. 
Due to the coarse station spacing between 30 N and 4 N, and the gap in
the section south of 4 S, we feel that the expediton DID NOT
successfully fulfill the overall requirements for WHP line P13.

C.) Hydrographic Measurement Techniques and Calibrations:
The following reports outline the techniques used for
measuring dissolved nutrients, oxygen, CFCs, alkalinity
and salinity. At the time of the preparation of this report,
data for the total carbon, carbon isotopes, and helium-tritium
measurements have not been reported to the Chief Scientist.
These will be submitted in revised P13.sea and P13.doc reports as they 
are received.

C1). NUTRIENTS:  
(Discussion provided by E. Howard Rutherford, USF.  July 10  1995) 
All analyses were done with an Alpkem RFA/2  320 autoanalyzer.  
The methods used were  modified from those recommended by the 
Alpkem Corporation.  Working nutrient standards used were a 
mixture of phosphate, silica, nitrate and nitrite in a low nutrient 
natural seawater matrix.  Simultaneous analyses were run on the 
RFA/2 for all of these nutrients.  

Silica:  The technique utilizes the reaction of dissolved silicate 
with a molybdate solution to produce a silico-molybdate complex 
which is then reduced by addition of stannous chloride to form an 
intensely blue-colored molybdenum compound that is measured 
spectrophotometrically at its absorbance maximum of 815nm. The 
primary standard used was prepared from pure silicon dioxide fused 
and dissolved in basic solution.

Phosphate: Under acidic conditions orthophosphate reacts with 
molybdenum (VI) and antimony (III) to form a phosphoantimonyl-
molybdenum complex which is subsequently reduced by the addition 
of ascorbic acid. The  mixed valence complex produced by the 
reduction is measured spectrophotometrically at its absorbance 
maximum of 880nm.  The primary standard was solid KH2PO4 
weighed out before the cruise.
 
Nitrite:  At pH between 1 and 2 all nitrite undergoes diazotization 
with sulfanilamide and subsequent coupling with N-1-
naphthylethylenediamine. The azo dye formed is measured 
spectrophotometrically at 540nm.  The primary standard was pre-
weighed NaNO2.

Nitrate+Nitrite:  Nitrate present in the sample was reduced to 
nitrite by cadmium metal in an open tubular cadmium reactor.  
Nitrate + Nitrite was then measured by the nitrite method described 
above.  The primary nitrate standard was pre-weighed KNO3.


Procedure

Samples were analyzed as soon as possible after each cast (usually 
within  2-4 hours).    For each chemistry a set of five standards 
prepared by additions of known amounts of nutrient to a low 
nutrient sea water was analyzed at the beginning and end of each 
analytical run. Analytical runs for the 36 bottle rosette cast take 
about three hours to complete.  At least every hour the slope of each 
standard curve was redetermined by analyzing the low nutrient sea 
water and an intermediate standard. The analytical blank used in the 
RFA/2 sample runs  (the blank is assumed to contain no analyte for 
all four chemistries) was de-ionized water produced onboard the 
R/V Vickers.  The voltage resulting from the difference in 
refractive index between blank and samples was sufficient to 
influence computed sample concentrations in the phosphate and 
nitrite analyses.   Magnitudes of these corrections were determined 
nine times during the cruise.  Standards and blanks were all run in 
triplicate and samples in duplicate.  

Calculations
Drift of standard curve slopes has been found to be generally linear 
with time (see the "Nutrients" section of the WOCE Operations 
Manual, July 1991, section author Lou Gordon).  Slope was re-
determined at least every hour and drift between determinations 
was assumed to be linear.  Drift of baseline voltage also was 
assumed linear for periods up to one hour.   Each sample peak height 
was corrected for refractive index difference between blanks and 
samples and for baseline and standard curve drifts, assuming linear 
drift between determinations.

c2.) Dissolved Oxygen
(discussion provided by Kirk Hargreaves, PMEL.  15 Dec 1995)

	Oxygen samples were drawn immediately after CFC's and Helium.  
Calibrated 125ml nominal volume iodine determination flasks (Corning 
5400-125) were used for sampling.  Flasks were parially filled with sea 
water, capped, shaken, and emptied three time.  Then, sea water was 
allowed to flow freely throuh the sampling tube and any air bubbles 
tapped away.  The tube was then pinched off, inserted into the flask, and 
slowly opened to avoid any turbulence.  Once completely opened, a wrist 
watch was used to time the filling rate (typically 7 seconds).  Two more 
flask volumes were allowed to overflow the flask using the watch as a 
reference.

	Regeants were introduced immediately after sampling.  The MnCl2
reagent tube was slowly inserted to the bottom of the flask and the reagent 
introduced.  Then the NaOH/NaI regeant tube was inserted halfway into the 
flask and the reagent introduced.  Both regeant dispensers were equipped 
with Brinkmann Anti-diffusion buret tips (catalog #6.1541.010) to prevent 
water exchange with the reagents.  NOTE: more testing should be done to
determine if the buret tips introdiced significant mixing of the surface 
water with the low oxygen water in the flask.  The low oxygen data does 
not indicate any variation which would be expected from such mixing.  
Reagents were made to WOCE specifications as described by Culberson (1992).

	Flasks are capped at this point and vigourously shaken. After 
station 49, distilled water from a squirt bottle was used to seal the 
caps (before station 49 it was assumed expansion due to heating would 
maintain the seal.  This was incorrect.  After at least 20 minutes, the 
flask would be reshaken and, after station 49, resealed.  Time until 
reshake varied from 20 minutes to 2 hours.

	Samples were analyzed no earlier than 20 minutes and no later 
than 12 hours after being reshaken.  The samples for an entire station 
would be acidified, restopped and reshaken.  Before titration of a 
sample, its stopper was removed and washed down.  Typically, one or two 
open flasks would be waiting for titration.  The previous three steps are 
not ideal and probably lead to errors in the oxygen values.  Data 
suggests this is on the order to 0.2 umol/kg.

	Titration was done using Carpenter's (1965) whole bottle technique with
a modification of the system described by Friederich, et al (1991).  A
Kloehn 50100 Syringe Drive with a 5 ml buret was used to dispense
titrant (nominal 0.05 N) and has a linearity of 0.05%.  New software to
run the system was written by K.Hargreaves in Turbo C++ with Turbo
Vision, but in hindsight it would have been better to use Friederich's
software.
 
	Standardization was done using approxiametly 0.01N potassium
iodate solutions prepared from pre-weighed potassium iodate crystals. 
Buoyancy and temperature corrections were applied to get the actual
standard strength at the time of standardization.  Standard was dispensed
with a 1ml Lab Industries Repipet with a calibrated delivery accuracy of
0.03% (under ideal conditions).  Several different total volumes
(typically 1, 3, 5, 7, 9, 11, 13, and 15 ml) were used to generated a
curve.  Also, several 1ml aliquots were used to enure a good blank.  A
linear least squares fit was calculated using the algorith from "Numerical
Recipes in C" (Press, 1988).  The normalized chi-squared parameters was
used to determine goodness of fit. 

	Each new standard was compared to a reference standard.  All
except one agreed to within 0.3%.  A correction factor was applied to
samples run with the standard that did not agree, on the assumption that
that standard was improperly weighed.  Also, standards were compared to
potassium iodate from a different manufacturer.  No significant difference
was found.
 
	From duplicate oxygen samples drawn, the estimated 
reproducibility is 0.5 umol/kg.  The accuracy of the standardization is 
estimated to be 0.4%.  This is calculated by adding by quadartures the 
repeatability of the standards (0.3%), the drift in the standardization 
in half a day (0.25%) and a 0.1% estimate of the accuracy of the 
standards.  The total accuracy is esimated to be 0.4% of value + 0.5 umol/kg.

	Oxygen were converted from umol/l to umol/kg by dividing by the 
density of the water at the time of sampling.  Water temperature was 
measured using a Cole-Parmer G-08497-00 Pt-RTD thermometer together with a 
Sensing Devices GW2107-01 thin film 100 ohm Pt-RTD (not calibrated, 
however).  Density was calculated using the formula in Culberson (1992).

	Also, the amount of oxygen present in the reagents (0.0017 ml O2 
= 0.076 umol O2, Culberson) was subtracted from the total measured amount 
of oxygen in the flask.

C3.) Bottle Salinity Measurements
(discussion provided by D.Greeley, PMEL. 11 April 1996)
     The salinity analysis aboard R/V John Vickers in the fall of 1992
was determined exclusively with a Guildline 8400 Autosal. This
instrument was located in a temperature controlled van located on
the aft end of the ship. The van was kept at 20.5 degrees celsius
+/- 1 degree celsius. The bath of the autosal was kept at 21 degrees
and proved to be very stable throughout the cruise. Standardization
of the autosal was carried out with IAPSO Standard Seawater batch P114.
There were ampoules of standard water which was clearly incorrect by
comparison to the other vials and thus were not used. The P114 standard
water was also compared to 5 ampoules from another batch of IAPSO water,
P90. The results from this comparison agreed favorably with the Scripps
comparison done in 1986 (Mantyla, Arnold: Standard Seawater Comparisons
Updated, Journal of Physical Oceanography, vol 17, 543-548, 1987). 

C4.) CFC Measurements
(discussion provided by J.Bullister, PMEL 11 April 1996)
  
     CFCs were usually the first water sample collected from the 10 liter
bottles.  Care was taken to co-ordinate the sampling of CFCs with other
gas samples to minimize the time between the inital opening of each
bottle and the completion of sample drawing.  In most cases, helium,
tritium, dissolved oxygen, total CO2, alkalinity and pH samples were
collected within several minutes of the intial opening of each bottle.
CFC samples were collected in 100 ml precision glass syringes, and held
immersed in a water bath until processing.

     The CFC analytical system functioned relatively well during this
expedition.  The CFC system was installed in a specially designed
laboratory van located on deck, and was isolated from possible
contamination from high levels of CFCs which are sometimes present in
air inside ship laboratories.  Concentration of CFCs in air inside this
van were usually close to those of clean marine air.

     Concentrations of CFC-11 and CFC-12 in air samples, seawater and gas
standards on the cruise were measured by shipboard electron capture gas
chromatography, according to the methods described by Bullister and
Weiss (1988).  The concentrations of CFC-11 and CFC-12 in air, seawater
samples and gas standards are reported relative to the SIO 1986
calibration scale.  CFC concentrations in air and standard gas are
reported in units of mole fraction CFC in dry gas, and are typically in
parts-per-trillion (ppt) range.  Dissolved CFC concentrations are given
in unit of picomole CFC per kg seawater (pmol/kg). CFC concentrations
in air and seawater samples were determined by fitting their
chromatographic peak areas to multi-point calibration curves, generated
by injecting known volumes of gas from a CFC working standard (PMEL
cylinder 71489) into the analytical instrument.  This concentrations
of CFC-11 and CFC-12 in this working standard were calibrated versus a
primary CFC standard (CC36743) before and after the cruise.  No
measurable drift in the working standard could be detected during this
interval. Full range calibration curves were run at 1 to 2 day
intervals.  Single injections of a fixed volume of standard gas were
run much more frequently (at intervals of 1 to 2 hours) to monitor
short term changes in detector sensitivity.  The estimated
reproducibility of the calibrations is about 1.3% for CFC-11 and 0.5%
for CFC-12.   We estimate a precision (1 standard deviation) for
dissolved CFC measurements of about 1%, or 0.005 pmol/kg, whichever is
greater.

    Sample loops filled with CFC-free gas, and syringe samples of
CFC-free water (degassed in a specially designed glass chamber) were
run to check sampling and analytical blanks.   CFC-11 and CFC-12
concentrations measured in deep samples along the section were
typically in the range of 0 to 0.007 pmol/kg, near the detection limit
of the analytical system (~0.004 pmol/kg).  Previous studies (Warner, et al 1996) of
time-dependent tracers in this region of the Pacific indicate that
waters at densities sigma0>27.4 should have CFC concentrations near zero
at present.  We attribute the low level CFC signal in deep samples to
the slow release of CFC from the walls and O-rings of the 10 liter
bottles into the seawater sample during storage, and to contamination
during the transfer and storage of the seawater samples in glass
syringes prior to analysis. Based on the median concentrations observed
in deep water samples along the secion, the following  blank correction 
were applied to the seawater measurements:

CFC-11 blank corrections applied (in pmol/kg):
Sta.  1-43:   0.010 pmol/kg
Sta. 44-88:   0.008 pmol/kg

CFC-12 blank corrections applied (in pmol/kg):
Sta. 1-4      0.000
Sta. 5-23     0.021
Sta. 24-27    0.034
Sta. 28-52    0.018
Sta. 53-88    0.009

As a result of this blank correction, some concentrations reported for
deep samples are less than zero.

   
     A number of water samples had anomously high CFC11 and/or CFC11
concentrations relative to adjacent samples.  These high values
appeared to occur more or less randomly, and were not clearly
associated with other features in the water column (eg. elevated oxygen
concentrations).  In most cases, only one of the 2 CFCs measured showed
these anomolously high levels.  This suggests that the high values were
due to analytical variabilty or isolated low-level contamination
events. These samples are included in this report and are flagged as
either 3 (questionable) or 4 (bad) measurements.  Approximately 181 
analyses of CFC-11 and  76 analyses of CFC-12 were given flags of
3 or 4.
