CRUISE SUMMARY

Cruise track:
The track of the cruise is shown in Figure 1.

Type and number of Stations:
Two types of stations were occupied:

_ Long stations: 3 CTD/rosette casts to get 36 water samplings from the surface 
  to the bottom.
_ short stations: 2 CTD/rosette casts to get 24 water samplings  from surface to 
  1600m, but with CTD down to the bottom..
_ 28 long stations and 21 short stations were occupied from 69°S to 44°S at 
  30°E. The other stations were adapted to the depth, especially near the 
  antarctic continent.  The location of the CTD stations are shown in Figure 2.
_ 113 XBT probes, T6 and T7 type, were launched along the track of the cruise 
  between the stations. Their locations are indicated in Figure 3 and in the 
  summary Table 1.


Sampling accomplished.

Salinity, Temperature, Pressure and Oxygen concentration were measured using a 
CTD probe and Temperature also with XBT; The location in the water column of the 
measurement of these parameters all along the section is shown in Figure 4. 
Water bottle samples were collected,  using a 12 bottle rosette with 12 litres 
Niskin/General Oceanic water sampling bottles; shipboard measurements of 
Salinity, Oxygen, Nutrients (Nitrate, Nitrites, Phosphate and Silicate), Total 
Inorganic Carbon, Total Alkalinity as well as the CFC-11 and CFC-12 
concentrations were made on all the bottles collected. The locations in the 
water column of the bottle samplings of these parameters are shown in Figure 5a.
	
Additional samples were collected for shore based laboratory measurements: 
Tritium, Helium-3, Carbon-14 (small samples), Oxygen-18, Carbon-13 and Barium. 
The locations in the water column of these samplings are respectively shown in 
figure 5b, 5c, 5d, and 5e.

Scientific programme and methods.

The aim of the CIVA programme was to study the circulation and the ventilation 
of the Antarctic ocean in the Indian sector, especially in the western zone of 
this sector. The principal objectives of this programme were to study:
  _ the flux at the Atlantic/Indian ocean boundary
  _ the zonal circulation in this region
  _ the evolution of the Weddell Antarctic bottom water
  _ the air-sea flux of CO2 in this region
  
The Marion Dufresne being also a supply ship for the French Indian ocean 
subantarctic islands, she departed La Réunion for Kerguelen archipelago on 
January 23, and occupied  the station Kerfix (WOCE station SRS1), 60 nautical 
miles south of Kerguelen, to test the CTD and the rosette.
 	
The CTD used was a Niel Brown Mark III instrument equipped with a dissolved 
oxygen sensor. The rosette, manufactured by General Oceanics, was equipped with 
12 Niskin bottles of 12 litres manufactured by General Oceanics and a 10 kHz 
location pinger. The cable was a 8.6mm steel rope and the winch was built by 
Kley France. After each cast the rosette was secured on the deck and washed with 
fresh water, especially the sensors which were then covered with protective 
housings; samples were collected following the order recommended in the WOCE 
operations manual: CFC, Helium, Oxygen, TCO2+TA, Carbon-14, Tritium, Carbon-13, 
Oxygen-18, Nutrients, Salinity, Barium. The temperature, pressure and 
conductivity sensors of the CTD were calibrated at IFREMER in Brest before and 
after the cruise. The conductivity and oxygen sensors were also calibrated using 
data collected during the cruise on the bottles taken at all the stations: 
Salinity was measured with a 8400 type Guildline salinometer in a constant 
temperature laboratory and Oxygen by an automatic potentiometric titration 
system (Metler DL21).
	
Samples were collected from each Niskin bottle for shipboard measurements of 
nutrients (Nitrate, Nitrites, Silicate and Phosphate) with two automatic 
Technicon AAII analysers, Total Alkalinity and Total Inorganic Carbon with a 
semi-automated potentiometric titration system (Radiometer) and Total Inorganic 
carbon with a coulometer UIC Coulometrics 5011. Samples were also collected with 
Pyrex 100ml syringes directly on all the Niskin bottles to measure CFC-11 and 
CFC-12 with a Shimadzu GC8A gas chromatograph in a portable laboratory located 
on the deck of the ship.
	
All the samplings were performed on the deck. The methods of measurement are 
reported later in this report.


Underway measurements:

XBTs were launched between the stations every about 10 nm using a Sippican 
system. Acoustic Dopler Current Profiler measurements were made with a R.D. 
Instruments ADCP only on the way from Antarctica to Durban; It was the first 
time that this instrument was used on the R/V Marion Dufresne and some problems 
arose especially during the transits, due to the instrument itself and the 
roughness of the sea. Underway measurements of Temperature and Salinity were 
made by a Bisset-Berman thermosalinograph;  Depth was recorded all along the 
track of the cruise on thermal paper using an EDO system. Fugacity of carbon 
dioxide was measured all along the track of the cruise with a Siemens IR 
analyzer, together with fluorescence with a Turner fluorometer and Oxygen with 
an Orbisphere Laboratory sensor.

Major Problems encountered during the cruise.

Several technical problems arose during the cruise and a sanitary evacuation 
imposed to go directly to Durban when the ship was at 54S. Twelve days were lost 
and the section expected to be occupied was not entirely completed. 

When the cast was at a depth greater than 4500/5000m the General Oceanics 
rosette presented a malfunctioning from time to time: either there was no back 
signal but the bottle closed, or there was a back signal but the bottle did not 
close, or there was a double-trigging of the bottles. Although the tension of 
the trigging lanyards was reduced this problem remained until the end of the 
cruise for the deep casts.

We had problems with the pumps of the "Autosal" salinometer, although this 
apparatus was new, especially when the sea was rough: it was difficult or at 
least very long to fill the cell with seawater. The instrument was disassembled 
and the cell was cleaned and the pumps were checked. Nevertheless the problem 
was not entirely resolved.

We also had a problem with the winch, the wheel of which  broke down; it was 
repaired but the cheeks were not exactly parallel and the wire could not be 
rewound well and the deep casts took a longer time than usually.

Measurement Techniques and Calibrations.


Salinity
(M. Fieux and T. Huck)

Salinities were measured with a Guildline Autosal Model 8400B Laboratory 
salinometer. It was calibrated for each set of measurements (about daily) with 
IAPSO Standard Seawater batch P-121. The cell was rinsed and filled with 
distilled water after each set of measurements. Before the standardization, the 
cell was rinsed at least ten times with seawater from previous set of samples, 
then at least 3 times with Standard Seawater and 5 measurements were made on 
this Standard Seawater in order to calibrate the instrument. The cell was rinsed 
3 times between each sample and 3 measurements were made; All the measurements 
were made between 24 and 48H after the samplings.  The reported salinity data are 
the arithmetic means of the 3 measurements. 

The apparatus was located in a laboratory container, the temperature of which 
was stabilized at about 1°C below the temperature of the salinometer water bath. 
This was 18°C when the atmospheric temperature was low and 21°C when the outside 
temperature was greater than about 15°C. At each station at least 2 or 3 
duplicate samples were collected; the differences of the two measurements are 
shown in Table 4.  

The samples were collected in IAPSO bottles which were stored in the same 
laboratory container at least 10 hours before the measurements.


Oxygen: 
(B. Schauer)

An automated potentiometric titration system (Mettler DL21) was used to measure 
oxygen on the samples collected in all the Niskin bottles, according to the 
Winkler method revised by Carpenter (1969). Samples were collected in special 
Pyrex flasks with a grounded stopper designed in such a way that approximately a 
volume equivalent to the one of the titrant to add was preserved for the 
titration. The flask was rinsed three times with seawater and filled in order to 
overflow three times its volume. The concentration of the titrant (Na2S2O3,5H2O) 
was measured with a potassium iodate (KIO3) solution prepared by weight in a 
shore based laboratory before the cruise and stored in recycled standard 
seawater ampoules. Duplicate measurements were made on several samples; the 
differences are shown  in Table 4.


Nutrients: 
(J.F. Minster and J. Escalier)

The measurements of nutrients were  made using two automatic Technicon AAII 
analysers. 

Nitrates were reduced according to the Woods method (1967), adapted to the 
automatic systems by Grasshof (1983) and Tréguer and Le Corre (1974). Nitrites 
obtained are titrated with the colorimetric technique described by Benschreider 
and Robinson (1952). The cadnium column was a U-shaped Pyrex tube filled with Cd 
granulates whose diameters were 0.315 and 0.715 µm; the reduction occurred at 
room temperature.

Phosphates were measured using the Murphy and Riley method (1962), modified by 
Tréguer (1976); The reaction occurred at 37°C.Silicates were measured according 
to the Mullin and Riley technique (1962) revised by Grasshoff (1983) and Treguer 
(1976); the reaction occurred at 37°C.Samples were collected in 125 ml 
prolypropylene flasks after three rinsings. Analyses were performed immediately 
after the sampling of the water.  Replicate samples were taken at all the stations 
The difference between the two measurements are shown in Table 4.Standard 
solutions were prepared by diluting NO3, PO4 and SiO2 standards with surface 
seawater collected near la Réunion island, filtered on 0.45 µm filter and stored 
at room temperature.

  _ NO3 standard was a 5000 µmol/kg KNO3 solution
  _ PO4 standard was a 500 µmol/kg  KH2PO4 solution
  _ SiO2 standard was a 17000 µmol/kg Na2SiO3 solution.

CFC-11 and CFC-12 
(B. Schauer):

The measurement of CFC-11 (trichlorofluoromethane) and CFC-12 (dichloro- 
difluoromethane) were performed by a Shimadzu GC8A electron -capture gas 
chromatograph, according to the method described by Bullister and Weiss (1988); 
The peacks were integrated using a Spectra Physics SP4920 integrator during the 
measurements; they will be checked in a shore-based laboratory using the Winner  
programme.

Seawater was collected in 100 ml glass syringes, with a metal tap, directly on 
the Niskin bottles when the rosette arrived on the deck. The Niskin bottles were 
previously cleaned with Decon detergent and the O-rings and taps were cleaned 
and put in an oven under low pressure at 60°C during 24H. The syringes were 
stored in  an open tank where a flow of surface water was continuously running. 
All the measurements were done in the 5 hours following the samplings.
 
The ECD detector signal was calibrated at each station with an air from Kerguelen 
Island, whose CFC-11 and CFC-12 concentrations (close to the ones in seawater) 
were previously calibrated relatively to SIO standards with a precision of 0.5% 
for both the CFC.
 
The precision of the method was tested at station 12 and duplicate samples were 
collected at all the stations. the results of these measurements are shown in 
Table 3 and Table 4 respectively. At station 12, measurements were made on 9 
Niskin bottles; the precision were 0.4% for CFC-11 and 1.1% for CFC-12, 
including the blank correction which was not taken into account for all these 
preliminary data. The signals were checked using Winner program in a base 
laboratory after the cruise.

Total Alkalinity, TA p and Total Inorganic Carbon, TCO2 p 
(C. Brunet):

Samples were collected in 500 ml Pyrex flasks with a screw stopper; the flask 
was rinsed twice with seawater and filled in order to overflow twice its volume.

A potentiometric titration derived from the method developed by Edmond (1970) 
was used to estimate Total Inorganic Carbon (TCO2 p) and Total Alkalinity (TA 
p). The titration system was composed of a Radiometer ABU 80 burette, a 
Radiometer PHM80 pHmeter and a PC/AT Tandon micro-computer to drive the burette 
and record the data. The titration curve was used as recommended in the US 
Department of Energy report (DOE, 1991) to determine TCO2 and TA. The acid (HCl, 
0.1N) used for the titration was calibrate once or twice a day with the 
Reference Material prepared by A. Dickson from Scripps Institution for the JGOFS 
programme. The measurements were made between 12 and 48H after the sampling. 

To test the precision of the method, replicate samples were taken at all the 
stations The difference between the two measurements are shown in Table 4. 
Another way to estimate the precision of the measurements is to calculate the 
regression curve of TCO2 versus potential temperature in deep water. the 
calculation was made on the 460 samples whose temperature is between -0.8°C and 
0.4°C; 14 data of TA and 22 of TCO2 were rejected because very far from the 
regression curve. This is possibly due to bad samplings or any problem during 
the titration. The standard deviation was 2.4µeq./kg  for TA and 3.7 µmol/kg 
for TCO2.

	
Total Inorganic Carbon, TCO2 c 
(B. Schauer):

Samples were collected in 500 ml Pyrex flasks with a screw stopper; the flask 
was rinsed twice with seawater and filled in order to overflow twice its volume.

A coulometric titration described by Johnson et al (19)  was used with a 5011 
UIC Coulometrics coulometer. Phosphoric acid was used for the titration and 
nitrogen for the bubbling in the stripper. A micro-computer drive the coulometer 
and the device used for the titration.

The calibration of the method was made using sodium carbonate solutions prepared 
under nitrogen atmosphere whose concentrations were between 0 and 2200 mmol/kg. 

To test the precision of the method, replicate samples were taken at all the 
stations The difference between the two measurements are shown in Table 4.


CTD

The pressure and temperature sensors of the CTD probe were calibrated at the 
IFREMER standard laboratory in Brest before the cruise. As the CTD was used also 
by the cruise following CIVA-1 (ANTARES-1) on board the Marion Dufresne, the 
probe was calibrated a second time in the same laboratory after the cruise
	
Conductivity and oxygen sensors were calibrated using salinity and oxygen 
concentrations measured on the Niskin bottles of the rosette.

--------------------------------------------------------------------------------
2/3/98    Anderson  BTL/SUM        Reformatted by WHPO, See Note:
  Files i06_sum.txt and i06_hyd.txt were reformatted to conform with what is, at 
  this time, the WHP formats.   This consisted mostly of adding spaces and 
  shifting data.  The following are other discrepancies that were found.  Some
  that were obvious were "corrected" others were left as is for someone else to 
  determine what should be done.--Sarilee Anderson, 3 Feb. 1998

  i06_sum.txt:
  --record 136 longitude input as 29 60.0 - changed to 30 00.0
  --record 420 max. pressure input as 288?2 - changed to 288.2
  --records 516, 517, and 518 all had the date as 31393 - changed to 031393

  i06_hyd.txt:
  --SAMPNO - these are strange numbers 10, 20 30,40,1750,2000, as if they were 
    desired depths (pressure) for sample.  Doesn't cause a problem, just strange.  
    There are even some that have F-20 as a sample no, these are usually the 
    deepest sample(s).

  --Station 12, cast 1 and cast 4 - these casts do not have  CTDPRS, CTDTMP, 
    CTDSAL, CTDOXY, THETA, SILCAT, NITRAT or PHSPHT.  But they do have SALNY, 
    OXYGEN, CFC-11, CFC-12, and TCARBN.  WOCECVT will not convert them because 
    there are no pressures (depths)

  --Station 25, records 720 to 731, sample 325 bottle 12 to sample 1600 bottle 
    1. data screwed up.  THETA, SALNY, OXYGEN, and SILCAT columns do not have the 
    correct values.  QUALT1 flags not much help in determining what the problem 
    might be.  Values aren't even close to what they should be.  Some values might 
    be in the wrong columns, but that does not account for everything.

  --Station 28, record 811 (last record in file) is incomplete.

  The .hyd file stops at sta. 28, but the .sum file indicates there should be 52 
  stations.

  In the following stations the cast number in the .sum file does not agree with 
  the cast number in the .hyd file.

  Station  cast #s    cast #s
    #s     in .sum    in .hyd
  ---------------------------
     2     1 and 3    1 and 2
     3     1 and 3    1 and 2
     7     1 and 3    1 and 2
     9     1 and 3    1 and 2
    11     1 and 3    1 and 2
    15     1 and 3    1 and 2
    17     1 and 3    1 and 2
    19     1 and 3    1 and 2
    21     1 and 3    1 and 2
    23     1 and 3    1 and 2
    25     1 and 3    1 and 2
    27     1 and 3    1 and 2

  I'm guessing the .hyd is correct and the .sum is incorrect.  But I did not 
  change either of them.

  Station 25 on I06S has columns out of order (temperature and salinity switched 
  etc etc).  Can you please regrid all properties for I06S, leaving out station 
  25?  It's too much trouble for me to correct the data set right now.

  Steve and Jerry - PLEASE keep this email in your comments for I06S which would 
  be forwarded to a DQE or given to Dave Muus or Sarilee to fix before the data 
  set is sent to a DQE.  

  The data set should definitely be fixed before it is released to anyone else.  
  The problem is in station 25 cast 1, where the columns are in a different 
  order from all other casts on the section.

9/16/98   Minster   NUTs           Data are Public
  in view of the age of the data you are mentioning, I consider that they should 
  be made available in the largest possible form, provided their origin is 
  described in the data files, CD Roms or plots, and to the largest possible 
  population of scientists, provided it is asked to them they refer to the 
  initial origin of the data when they use them. -- Sincerely yours, JF Minster
					
9/18/98   Anderson  CTD            Reformatted by WHPO; See Note:
  Completed reformatting the ctd files.  Only the headers needed information to 
  make them complete.  Added NO. RECORDS= value, and changed the station and 
  cast numbers.  The originator had all casts set to 1 and the station numbers 
  as pointed out by Lynne) were numbers like 11, 21, 33 where the first number 
  is the station number and the second is the cast number, i.e. 33 is station 3, 
  cast 3, etc.

  In most cases the originator reported more than one cast.  There is not a 
  standard in the files naming convention for this.  I named the files 
  i06sxxxx.wct for the deepest cast - usually cast 1.  The other files were 
  named i06sxxxx.x.wct, xxxx being the station number and the .x being the cast 
  number.

9/29/99   Falkner   BA             No Data Submitted; See note:
  The quality of the Ba data from most WOCE legs in the Indian Ocean turned out 
  to be quite  poor; far worse than attainable analytical precision (+/-20% as 
  opposed to 2%). We recorded many vials which came back with loose caps and 
  evaporation associated with that seems to be the primary problem.  The only 
  hope I have of producing a decent data set is to run both Ba and a 
  conservative element simultaneously and then relating that to the original 
  salinity of the sample.  We will be taking delivery on a high resolution ICPMS 
  here at OSU sometime this winter which would make the project analytically 
  feasible and economical.  I do not presently have the funds in hand to do this 
  and so have archived the samples for the time being. I don't think the WHPO 
  would derive any benefit from the present data set.   KKF
					
8/25/00   Key       DELC14         Final Data Rcvd @ WHPO; See Note:
  The data file I just submitted, "I6S.C14" is NOT my data. I sent on request
  from Piers.  I received the original file from V. Leboucher. This data is 
  public and has been published:

  Leboucher, et al., 1999, Radiocarbon, 41(1), 51-73. 

  In the original file, the casts were identified by a letter code. I replaced 
  the letters with numbers corresponding to the hyd file at WHPO and then 
  merged. The replacement scheme was:

    "S"=3
    "I"=2
    "P"=1

  There was one id error in the original file which I fixed prior to merging. 
  The errors are as reported with the original data.  I carried out QC and 
  assigned all flag values.
