SAZ-SENSE, Marine Science Cruise AU0703
- Oceanographic Field Measurements and Analysis


MARK ROSENBERG
ACE CRC, Hobart, Australia
September, 2007



1.  INTRODUCTION

Oceanographic measurements were collected aboard Aurora Australis cruise 
au0703 (voyage 3 2006/2007, 17th January to 20th February 2007) as part of 
the "SAZ-SENSE" experiment south of Tasmania, between 43° and 55° south. A 
total of 109 CTD vertical profile stations were taken to various depths, 
focusing chiefly on the upper water column. Over 1300 Niskin bottle water 
samples were collected for the measurement of salinity, dissolved oxygen, 
nutrients (phosphate, nitrate+nitrite, silicate, ammonia and nitrite), 
dissolved inorganic carbon, alkalinity, particulate organic 
carbon/nitrogen/silicate, dissolved and particulate barium, thorium, 
dissolved organic carbon, ammonium, pigments, phytoplankton, bacteria, 
viruses, diatoms, amino acids, and other biological parameters (list 
incomplete), using a 24 bottle rosette sampler. Near surface current 
profile data were collected by a ship mounted ADCP. Data from the array of 
ship's underway sensors are included in the data set. 

This report describes the processing/calibration of the CTD and ADCP data, 
and details the data quality. An offset correction is derived for the 
underway sea surface temperature and salinity data, by comparison with near 
surface CTD data. CTD station positions are shown in Figure 1, while CTD 
station information is summarized in Table 1. 

During the cruise, various sites were occupied for multiple measurement 
activities, and these sites were named and referred to as "stations". Note 
however that in this report "station" refers to a single CTD cast i.e. CTD 
station 1 to 109 for the cruise.



2.  CTD INSTRUMENTATION

SeaBird SBE9plus CTD serial 704, with dual temperature and conductivity 
sensors and a single SBE43 dissolved oxygen sensor (serial 0178, on the 
primary sensor pump line), was used for the entire cruise, mounted on a 
SeaBird 24 bottle rosette frame, together with a SBE32 24 position pylon 
and 24 x 10 litre General Oceanics Niskin bottles. The following additional 
sensors were mounted:

  • Tritech 200 kHz and 500 kHz altimeters
  • Wetlabs ECO-AFL/FL fluorometer serial 296
  • Wetlabs C-star transmissometer serial 899DR
  • Biospherical Instruments photosynthetically active radiation (i.e. PAR) 
    sensor
  • old Antarctic Division PAR sensor

CTD data were transmitted up a 6 mm seacable to a SBE11plusV2 deck unit, at 
a rate of 24 Hz, and data were logged simultaneously on 2 PC's using 
SeaBird data acquisition software "Seasave". The transmissometer was 
plumbed inline with the main CTD sensors for the first 35 casts, with a 
closed tube joining the 2 transmissometer windows. The tube and plumbing to 
the transmissometer were removed after CTD 35.

The CTD deployment method was as follows:

  • CTD initially deployed down to ~20 m
  • after confirmation of pump operation, CTD returned up to just below the 
    surface (depth dependent on sea state)
  • after returning to just below the surface, downcast proper commenced

Cast depths varied according to the sampling requirements at each station, 
and full depth casts were only taken on 3 occasions.

Pre cruise temperature, conductivity and pressure calibrations were 
performed by the CSIRO Division of Marine and Atmospheric Research 
calibration facility (Table 2) (July to August 2006). Manufacturer supplied 
calibrations were used for the dissolved oxygen, fluorometer, 
transmissometer  and altimeters. PAR sensors were uncalibrated (raw voltage 
data only). Final conductivity and dissolved oxygen calibrations derived 
from in situ Niskin bottle samples are listed later in the report. 

For stations 49, 50 and 51, six seal tags (P.I. Judy Horsburgh) were 
attached to the rosette, to calibrate and check functioning of the tag 
sensors.



3.  CTD DATA PROCESSING AND CALIBRATION

CTD data were processed in Hobart. The first step is application of a suite 
of the SeaBird "Seasoft" processing programs to the raw data, in order to:

  • convert raw data signals to engineering units
  • remove the surface pressure offset for each station
  • realign the oxygen sensor with respect to time (note that conductivity 
    sensor alignment is done by the deck unit at the time of data logging)
  • remove conductivity cell thermal mass effects
  • apply a low pass filter to the pressure data
  • flag pressure reversals
  • search for bad data (e.g. due to sensor fouling)

Further processing and data calibration were done in a UNIX environment, 
using a suite of Fortran programs. Processing steps here include:

  • forming upcast burst CTD data for calibration against bottle data, 
    where each upcast burst is the average of 10 seconds of data prior to 
    each Niskin bottle firing
  • merging bottle and CTD data, and deriving CTD conductivity calibration 
    coefficients by comparing upcast CTD burst average conductivity data 
    with calculated equivalent bottle sample conductivities
  • forming pressure monotonically increasing data, and from there 
    calculating 2 dbar averaged downcast CTD data
  • calculating calibrated 2 dbar averaged salinity from the 2 dbar 
    pressure, temperature and conductivity values
  • deriving CTD dissolved oxygen calibration coefficients by comparing 
    bottle sample dissolved oxygen values (collected on the upcast) with 
    CTD dissolved oxygen values from the equivalent 2 dbar downcast 
    pressures
  • extracting the appropriate fluorescence and transmittance data to 
    assign to each 2 dbar bin

Full details of the data calibration and processing methods are given in 
Rosenberg et al. (in preparation), referred to hereafter as the CTD 
methodology. Additional processing steps, in particular for the 
fluorescence and transmittance data, are discussed below in the results 
section. For calibration of the CTD oxygen data, whole profile fits were 
used for each station.

Final station header information, including station positions at the start, 
bottom and end of each CTD cast, were obtained from underway data for the 
cruise (see section 6 below). Note the following for the station header 
information:

  • All times are UTC.
  • "Start of cast" information is at the commencement of the downcast 
    proper, as described above.
  • "Bottom of cast" information is at the maximum pressure value.
  • "End of cast" information is when the CTD leaves the water at the end 
     of the cast, as indicated by a drop in salinity values.
  • 12 kHz depth sounder data were not processed for this cruise, and all 
    bottom depth information are the values recorded at the time of CTD 
    logging i.e. as read from the "Echogram" display, with sound speed 1500 
    m/s. The Echogram display was often difficult to read through the 
    thruster noise, and bottom depth values are mostly approximate only.
  • "Bottom of cast" depths for CTD 38 and 43 are calculated from CTD 
    maximum pressure and altimeter value at the bottom of the casts.

Lastly, data were converted to MATLAB format, and final data quality 
checking was done within MATLAB.



4.  CTD AND BOTTLE DATA RESULTS AND DATA QUALITY

Data from the primary CTD sensor pair (temperature and conductivity) were 
used for this cruise, with the exception of stations 8 and 30 - for these 
two stations the primary sensors were fouled, and data from the secondary 
sensor pair were used.


4.1.  Conductivity/salinity

The conductivity calibration and equivalent salinity results for the cruise 
are plotted in Figures 2 and 3, and the derived conductivity calibration 
coefficients are listed in Tables 3 and 4. Station groupings used for the 
calibration are included in Table 3. International standard seawater batch 
numbers used for salinometer standardization were as follows:

station 1            P146
station 2 to 30      P147
station 31 to 63     P146
station 64 to 104    P147
station 105 to 109   P146

The salinometer (Guildline Autosal serial 62549) used for stations 1 to 104 
appeared stable throughout the cruise. Stations 105 to 109 were analyzed 
back in Hobart immediately following the cruise, using salinometer serial 
62550. Overall, CTD salinity for the cruise can be considered accurate to 
better than 0.0015 (PSS78).

Close inspection of the vertical profiles of the bottle-CTD salinity 
difference values reveals a slight positive biasing of the order 0.001 
(PSS78) for station 1, and a slight negative biasing of the same magnitude 
for station 47. This is most likely due to salinometer performance and/or 
bottle samples, and there is no significant diminishing of CTD salinity 
accuracy.


4.2.  TEMPERATURE

Primary and secondary CTD temperature data (t(D) and t(S) respectively) are 
compared for the cruise in Figure 4. CTD upcast burst data, obtained at 
each Niskin bottle stop, are used for the comparison. From previous cruises 
(e.g. Rosenberg, unpublished report, 2006), a very small pressure 
dependency of t(D)-t(S) for CTD704 of the order 0.0005°C is evident over 
the full ocean depth range. For cruise au0703, measurements were only taken 
down to ~2500 dbar, and a small pressure dependency similar to previous 
cruises is evident by the deepest measurements (Figure 4). Note that the 
magnitude of this pressure dependency lies within the assumed temperature 
accuracy of 0.001°C (i.e. the accredited temperature accuracy of the CSIRO 
calibration facility). Also note that without some temperature standard for 
comparison, it cannot be determined whether the 2 temperature sensors have 
the same or different pressure dependencies.


4.3.  PRESSURE

Surface pressure offsets for each cast (Table 5) were obtained from 
inspection of the data before the package entered the water. For station 
24, logging commenced when the CTD was already in the water, and the 
surface pressure offset was estimated from surrounding stations. 


4.4.  DISSOLVED OXYGEN

CTD oxygen data for his cruise were calibrated as whole profile fits - with 
the limited depth range for the CTD deployments, splitting profiles into 
separate shallow and deep calibrations was not required. The CTD oxygen 
calibration results are plotted in Figure 5, and the derived calibration 
coefficients are listed in Table 6. Overall the calibrated CTD oxygen 
agrees with the bottle data to well within 1% of full scale (where full 
scale is ~350 μmol/l above 750 dbar, and ~240 μmol/l below 750 dbar).

Reliable calibration of a CTD dissolved oxygen profile is only possible 
with an adequate profile of bottle oxygen samples. The Niskin bottle 
sampling scheme for this cruise resulted in many CTD stations with either 
low numbers of bottle oxygen samples, or none at all. For the former, only 
that part of the CTD oxygen profile covered by samples was usable; for the 
latter, CTD oxygen data were not usable. Figure 6 summarizes calibrated CTD 
oxygen data coverage.

Note that oxygen bottle samples for stations 105 to 109 were analyzed back 
in Hobart, immediately following the cruise.


4.5.  FLUORESCENCE, PAR, TRANSMITTANCE

All fluorescence and transmittance data have a calibration, as supplied by 
the manufacturer (Table 2), applied to the data. PAR sensor data are 
uncalibrated, and supplied as raw voltages. The data have not been verified 
by linkage to other data sources (e.g. chlorophyll-a concentration data, 
particulate data, etc). 

In the CTD 2 dbar averaged data files, both downcast and upcast data are 
supplied for fluorescence, PAR and transmittance. In these files, 
fluorescence and transmittance data are not in fact averages: fluorescence 
data are the minimum value within each 2 dbar bin, providing a profile 
"envelope" which minimizes the spikiness of the data; transmittance data 
are the maximum value within each 2 dbar bin, again minimizing the 
spikiness of the data. An additional parameter describing the spikiness of 
the transmittance data is supplied, calculated as follows. Pressure 
monotonic data (increasing for downcast, decreasing for upcast) are first 
formed from the full 24 Hz data, omitting equal pressure points as well as 
pressure reversals. For each transmittance reading tr(mon) in the montonic 
data, transmittance "spike size"  trsize is given by the deviation from the 
transmittance maximum envelope, i.e.

    trsize      = tr(intero) - tr(mon)

where

    tr(intero)  = trmax(bin1) + [(p(bin2) - p(bin1))/(p(bin2) - p(bin1) x 
                  (trmax(bin2) - trmax(bin1)]

    p(mon)      = the pressure value corresponding with tr(mon)
    p(bin1)     = the nearest 2 dbar pressure bin less than p(mon)
    p(bin2)     = the nearest 2 dbar pressure bin greater than p(mon)
    trmax(bin1) = the 2 dbar maximum transmittance value for pressure bin 
                  p(bin1)
    trmax(bin2) = the 2 dbar maximum transmittance value for pressure bin 
                  p(bin2)

(i.e. tr(intero) is the transmittance value from the 2 dbar transmittance 
maximum envelope, linearly interpolated to p(mon)). For a small number of 
cases in steep vertical gradients, tr(intero) is a small negative value. 
This is due to the pressure mismatch between the even pressure bin to which 
tr(max) is assigned, and the actual pressure value at which tr(max) occurs. 
For these cases, the tr(interp) value is changed to zero. Lastly, the 
transmittance "spikiness" trspike for each 2 dbar bin is the standard 
deviation of trsize values in each bin, i.e.

                 n
    trspike  = {[∑ (trsize(i) - trsize(mean))^2]/(n - 1)}^(1/2)
                 i=1   
where

    n = number of trsize values in the 2 dbar bin
    trsize(mean) = mean of the trsize values in the 2 dbar bin

In the bottle data files, fluorescence and transmittance (and PAR) values 
are the averages of 10 second bursts of CTD data, and thus include all the 
data spikes within each 10 second averaging period. For comparison with 
Niskin bottle data, these 10 second averages best represent (short of 
referring to the full 24 Hz data) what the Niskin bottle samples as the 
package moves up and down with the swell prior to bottle closure. Note that 
these fluorescence and transmittance data are different to the data in the 
CTD 2 dbar averaged files (described above).

The plumbing arrangement used for the transmissometer during the first 35 
stations (mentioned above in section 2) caused bad downcast transmittance 
data for several stations. These bad data, listed in Table 7, were removed 
from the data files.


4.6.  NUTRIENTS

Nutrients measured on the cruise were phosphate, total nitrate (i.e. 
nitrate+nitrite), silicate, ammonia, and nitrite (only up to station 86). 
Appendix 1 (by Neale Johnston) gives some details on analysis methods. 
Suspect nutrient values not deleted from the bottle data files are listed 
in Table 8. Nitrate+nitrite versus phosphate data are shown in Figure 7. A 
group of depressed phosphate values are evident in the figure, around 
nitrate+nitrite ≈ 5 µmol/l. These values are from the tops of various 
profiles up to station 32, and appear to be real features.

Only limited data were available from other cruises for comparison with the 
au0703 nutrient data, and only very rough comparisons were possible. In 
general, low level readings from the Lachat AutoAnalyzer, including low 
level near surface phosphate and nitrate+nitrite data, and all ammonia and 
nitrite data, should be used with caution. The accuracy for these low level 
values is unknown.


4.7.  ADDITIONAL CTD DATA PROCESSING/QUALITY NOTES

  • Station 3 - the primary CTD sensors were fouled for part of the 
    downcast profile, and these data were deleted from the 2 dbar averaged 
    file.

  • Station 7 - the salinity value flagged as -1 in the bottle data file 
    was due to a CTD data spike in the primary sensor pair.

  • Station 26 - after deployment of the CTD, there was no stop to wait for 
    the pumps to come on. Most of the downcast for this very shallow cast 
    was therefore unusable. 

  • Stations 27, 32, 34, 57 - after waiting for the pumps to come on, the 
    package was not returned to a shallower position to commence the 
    downcast (due to swell). The downcast profile for these stations 
    commences between 20 and 40 dbar.

  • Station 61 - top 2 Niskins tripped on the fly, due to heavy rolling of 
    ship.

  • Station 86 - the pressure sensor was fouled just prior to firing of 
    bottle 24. Data used for CTD burst averages were shifted forward by 100 
    scans (i.e. 4.17 seconds).

  • Stations 1 and 94 - logging ended before the CTD left the water. The 
    last few bins of upcast fluorescence, PAR and transmittance data are 
    therefore missing.

  • Station 96 - the CTD sensor tubes and fluorometer sensor cap were not 
    removed prior to deployment. The only usable profiles for this station 
    are transmittance and PAR.

  • For version of WOCE "Exchange" format bottle data file with µmol/kg 
    units for nutrient data (available on request) - a laboratory 
    temperature of 19°C was used for conversion of units from μmol/l to 
    μmol/kg.


4.8.  ADDITIONAL CTD SENSOR NOTES

  • The ocean bottom was rarely approached on this cruise, however on both 
    occasion where the bottom was in altimeter range, the 500 kHz altimeter 
    (50 m range) gave reliable readings, while the 200 kHz altimeter (100 m 
    range) did not work.

  • The secondary temperature sensor malfunctioned on several occasion 
    during the first 9 stations (possibly due to a bad connector), in turn 
    causing bad secondary conductivity data. When this occurred, secondary 
    conductivity data took a while to recover.

  • Data from the old Antarctic Division PAR sensor were unusable - not a 
    worry, as good data were obtained from the Biospherical Instruments PAR 
    sensor.



5.  ADCP

The hull mounted ADCP on the Aurora Australis is described in Rosenberg 
(unpublished report, 1999), with the following updates:

(i)  There is no longer a Fugro differential GPS system - all GPS data, 
     including heading, come from the Ashtech 3D system.

(ii) Triggering of the 12 kHz sounder and the higher frequency 
     hydroacoustics array are now separate, resulting in a higher ping rate 
     for the ADCP (linked to the higher frequency hydroacoustics array). 

Logging parameters and calibration coefficients for the cruise are 
summarized in Table 9. Current vectors for the cruise are plotted in 
Figures 8a and b; the apparent vertical current shear error for different 
ship speed classes is plotted in Figure 9.

In general, ADCP data are contaminated by ship's motion when the ship 
accelerates i.e. changes direction or speed. Noise and turbulence often 
diminish ADCP data quality when the ship travels at speeds greater than ~13 
knots, or during rough sea states. Thus the best quality ADCP data is when 
the ship is steaming in a straight line at a suitable constant speed, and 
during milder sea conditions. The most reliable data are collected when the 
ship is "on station" (on station data is defined here as data where ship 
speed ≤ 0.35 m/s).

An erroneous vertical ADCP current shear occurs when the ship is underway. 
This shear has a magnitude for this cruise of up to ~0.13 m/s over the ADCP 
current profile (Figure 9), although more often ~0.05-0.08 m/s. A likely 
cause for this error is acoustic ringing against a small air/water 
interface inside the transducer seachest. From Figure 9, when the ship is 
underway the effect is most significant over bins 1 to 10, and data from 
these bins should be treated with caution. Also from the figure, when the 
ship is travelling at ≤ 1 m/s the effect is no longer significant.



6.  UNDERWAY MEASUREMENTS

Underway data were logged to an Oracle database on the ship. Quality 
control for this cruise was largely automated.

1 minute averaged underway data are contained in the files sazsense.txt 
(column formatted text file) and sazsenseora.mat (matlab format). Note that 
the latitude and longitude data in these files are 1 minute instantaneous 
values (i.e. not averaged). 

Bathymetry data for the cruise were not processed, and depths are all null 
values in the underway data files.
 
Underway salinity data from the Antarctic Division thermosalinograph (in 
the oceanographic lab) display a response lag which becomes significant 
when crossing frontal regions where the horizontal gradients are high 
(Bronte Tilbrook, CSIRO, personal communication); these salinity data 
should not be used. Alternative underway salinity data were obtained from a 
separate CSIRO thermosalinograph in lab 1 (P.I. Bronte Tilbrook, CSIRO), 
and these data are considered reliable. Underway temperature data from the 
Antarctic Division hull mounted temperature sensor near the sea water inlet 
are good. A correction for the hull mounted temperature sensor and the lab 
1 salinity was derived by comparing the underway data to CTD temperature 
and salinity data at 8 dbar (Figures 10a and b). The following corrections 
were then applied to the underway data:

                            T = T(dls) - 0.022
                            S = S(dls) + 0.077 

for corrected underway temperature and salinity T and S respectively, and 
uncorrected values T(dls) and S(dls).

           Niskin bottle conductivity, found by using CTD pressure and 
           temperature from the CTD upcast burst data in the conversion of 
           Niskin bottle salinity to conductivity.

APPENDIX 1   NOTES ON NUTRIENT ANALYSES

Neale Johnston (CSIRO Marine and Atmospheric Research, Floreat, Western 
Australia)


Nutrient samples were run on a Lachat Quickchem series 8000 FIA. Samples 
were analyzed for silicate, phosphate, nitrate+nitrite, nitrite and 
ammonia.

The following methods were used:

  • silicate - Quickchem Method 31-114-27-1-D (i.e. in Lachat manual)

  • orthophosphate - Quickchem Method 31-115-01-1-G

  • nitrate+nitrite - Quickchem Method 31-107-04-1-A

  • ammonia - used an automated method based on the manual method in Watson 
    et al. (2005); a Shimadzu RF - 10Axl fluorescence detector was used in 
    the ammonia analysis.

  • nitrite used the same method as nitrate+nitrite, but with the cadmium 
    reduction column removed.

For all analysis, calibration and reference standards were made using 
nutrient depleted seawater (reference standards from Ocean Scientific 
International were diluted with nutrient depleted seawater). Calibration 
standards were run at the start and end of each run. Reference standards 
were run every 15 samples. The carrier for silicate, phosphate and 
nitrate+nitrite was artificial seawater (3.6% sodium chloride ). This 
carrier was taken to contain no silicate, nitrate+nitrite or phosphate, and 
was checked by observing the baseline voltage reading for each channel each 
time it was prepared. The carrier for ammonia was a 2ml/l sulfuric acid 
solution. The carrier solution was subject to contamination from 
atmospheric-born contamination. This was checked each run by checking the 
baseline and by running a known ammonia depleted sample against the 
carrier.

Baseline voltages changed slightly each time reagents were changed so where 
possible reagents and carrier were not changed at the same time.

Nutrient depleted seawater was depleted for nitrate+nitrite, phosphate and 
ammonia, but did often have low silicate values. This was corrected for 
each run.
