ABSTRACT:

CLIVAR Repeat Hydrography Cruise A13.5 in the South Atlantic on NOAA ship Ronald 
H. Brown was completed successfully during the period 8 March 2010- 18 April 
2010.  This cruise is part of a decadal series of repeat hydrography sections 
jointly funded by NOAA-OGP and NSF-OCE as part of the 
CLIVAR/CO2/hydrography/tracer program (http://ushydro.ucsd.edu).  The goal of 
the effort is to occupy a set of hydrographic transects over the global ocean 
with full water column measurements to study physical and hydrographic changes 
over time.  The 2010 A13.5 expedition began in Cape Town, South Africa and ended 
in Takoradi, Ghana.  Academic institutions and NOAA research laboratories 
participated on the cruise.  The A13.5 section ran nominally (~3°W-1°E) along 
the prime meridian from approximately 54°S to 5°N, repeating a section occupied 
on the AJAX expedition in 1983/1984.  A total of 129 full water column 
CTD/O2/LADCP/rosette casts were completed along the A13.5 section at ~30 
nautical mile (nm) spacing, with closer (20 nm) spacing between 3°S and 3°N.  
Approximately 3123 water samples were collected on these casts for analyses of a 
variety of parameters, including salinity, dissolved oxygen, nutrients, 
chlorofluorocarbons, (CFCs), SF6, dissolved inorganic carbon (DIC), alkalinity, 
fCO2, pH, carbon isotopes, dissolved organic carbon (DOC), total dissolved 
nitrogen (TDN), tritium and helium.

Underway data collection included upper-ocean current measurements from the 
shipboard ADCP, surface oceanographic (temperature, salinity, fCO2) and 
meteorological parameters from the ship's underway systems, bathymetric data and 
atmospheric measurements of CO2, CFCs, SF6 and ozone).

INTRODUCTION

The CLIVAR Repeat Hydrography Program focuses on the need to monitor inventories 
of CO2, tracers, heat and freshwater and their transports in the ocean.  Earlier 
programs under WOCE and JGOFS provided a baseline observational field for these 
parameters.  The new measurements reveal much about the changing patterns on 
decadal scales.  The program serves as a backbone to assess changes in the 
ocean's biogeochemical cycle in response to natural and/or man-induced activity.  
Global changes in the ocean's transport of heat and freshwater, which can have 
significant impact on climate, can be followed through these long-term 
measurements.  The CLIVAR Repeat Hydrography Program provides a robust 
observational framework to monitor these long-term trends.  These measurements 
are in support of:

  • Model calibration and testing
  • Carbon system studies
  • Heat and freshwater storage and flux studies
  • Deep and shallow water mass and ventilation studies
  • Calibration of autonomous sensors

This program follows the invasion of anthropogenic CO2 and transient tracers 
into intermediate and deep water on decadal timescales and determines the 
variability of the inorganic carbon system, and its relationship to biological 
and physical processes.  More details on the program can be found at the 
website:  http://ushydro.ucsd.edu

BOTTLE SAMPLING AND DATA PROCESSING

After a 1-day delay, NOAA Ship Ronald H. Brown departed Cape Town, South Africa 
on 8 March 2010 at 1400 UTC and ended in Takoradi, Ghana on 18 April 2010.

A total of 130 stations were occupied during the A13.5 cruise. One test station 
(Sta. 998) was occupied on the transit from Cape Town to the southern end of the 
A13.5 section, and Sta.1 -Sta. 129 were occupied on the A13.5 section.  The 
section was run from south to north.  A total 133 CTD/O2/LADCP/rosette casts 
(including 1 test cast and 3 reoccupations at stations 72, 79, and 82) were 
collected.  Eight Argo floats and 18 surface drifters were deployed.  CTD/O2 
data, LADCP data, and water samples (up to 24) were collected on most rosette 
casts, in most cases to within 10 meters of the bottom.

A 24 position, 11 liter bottle rosette frame was used on this cruise.  Salinity, 
dissolved oxygen, and nutrient samples were collected and analyzed from 
essentially all of the water samples collected.  Water samples were also 
measured for CFCs, SF6 ,fCO2, total CO2 (DIC), total alkalinity, and pH on most 
of the samples.  Additional samples were collected for 3He, tritium, 13C/ 14C, 
and DOC/TDN.

Water Sampling

The NOAA Ship Ronald H. Brown has two Markey DESH-5 winches.  The Aft winch was 
used for the test cast (station 998) and Stations 1-48 and 72/3-79/1.  The 
Forward winch was used for stations 49-72/1 and 79/3-129.  All but 5 rosette 
casts were lowered to within 3-20 meters of the bottom, using both the pinger 
and/or altimeter to determine distance.

Rather than close the bottles at the same (standard) depths at each station, 
four sampling plans were used in rotation to choose the vertical sampling depths 
throughout the CLIVAR/Carbon A13.5 section.  The goal was to provide better 
coverage and spatial patterns for later gridding of the various data sets.

Each bottle on the rosette had a unique serial number. This bottle 
identification was maintained independently of the bottle position on the 
rosette, which was used for sample identification.  Three bottles (at trip 
positions 17, 22 and 23) were replaced on this cruise, and various bottle parts 
were occasionally changed or repaired (see Appendix).  Bottle 17 was changed out 
after station 8 due to repeated problems with leaking; bottle 23 apparently 
closed in air at the start of station 82/1 and later imploded at depth, 
irreparably damaging bottle 22 in the process.

Rosette maintenance was performed on a regular basis. O-rings were changed and 
lanyards repaired as necessary. Bottle maintenance was performed after each cast 
to insure proper closure and sealing. Valves were inspected for leaks and 
repaired or replaced as needed.

The 24-place SBE32 carousel had occasional problems releasing individual bottle 
lanyards, causing mis-tripped bottles on a number of casts.  Repair attempts and 
bottle height/lanyard adjustments were made as the cruise continued, but these 
problems were not completely resolved during the cruise.


Bottle Sampling

At the end of each rosette deployment water samples were drawn from the bottles 
in the following order:


  • Chlorofluorocarbons (CFCs) and SF6
  • Helium-3
  • Dissolved oxygen
  • pH
  • Partial pressure CO2 (fCO2)
  • Dissolved Inorganic Carbon (DIC)
  • Total Alkalinity (TAlk)
  • Carbon-13 (13C) and Carbon-14 (14C) isotopes
  • Dissolved Organic Carbon (DOC)/Total Dissolved Nitrogen (TDN)
  • Tritium
  • Nutrients
  • Salinity

The correspondence between individual sample containers and the rosette bottle 
position (1-24) from which the sample was drawn was recorded on the sample log 
for the cast.  This log also included any comments or anomalous conditions noted 
about the rosette and bottles.  One member of the sampling team was designated 
the sample cop, whose sole responsibility was to maintain this log and insure 
accurate logging of the samples as they were collected, and to insure that 
sampling progressed in the proper drawing order.

Normal sampling practice included opening the drain valve before the air vent on 
each bottle. If any water escaped at this point it was noted as an air leak.  
This observation together with other diagnostic comments (e.g., "lanyard caught 
in lid", "valve left open") that might later prove useful in determining sample 
integrity were routinely noted on the sample log (see Appendix).  Drawing oxygen 
samples also involved taking the sample draw temperature from the bottle.  The 
temperature was noted on the sample log and was sometimes useful in determining 
leaking or mis-tripped bottles.

Once individual samples had been drawn and properly prepared, they were 
distributed for analysis.  On-board analyses were performed on computer-assisted 
(PC) analytical equipment networked to the data processing computer for 
centralized data management.


Bottle Data Processing

Water samples collected and properties analyzed shipboard were managed centrally 
in a relational database (PostgreSQL-8.0.3) run on a Linux computer system. A 
web service (OpenAcs-5.2.2 and AOLServer-4.0.10) front-end provided ship-wide 
access to CTD and water sample data.  Web-based facilities included on-demand 
arbitrary property-property plots and vertical sections as well as data uploads 
and downloads.

The Sample Log (and any diagnostic comments) was entered into the database once 
sampling was completed.  Quality flags associated with sampled properties were 
set to indicate that the property had been sampled, and sample container 
identifications were noted where applicable (e.g., oxygen flask number).

Analytical results were provided on a regular basis by the various analytical 
groups and incorporated into the database. These results included a quality code 
associated with each measured value and followed the coding scheme developed for 
the World Ocean Circulation Experiment (WOCE) Hydrographic Programme (WHP) 
[Joyce, 1994].

Various consistency checks and detailed examination of the data continued 
throughout the cruise.

A summary of Bottle Data Quality Codes and sampling comments are included in the 
Appendix.

CTD Data Acquisition

The CTD data acquisition system consisted of an SBE-11plus (V1) deck unit s/n 
367 and a networked Dell Optiplex 755 PC workstation running Windows XP 
Professional. SBE SeaSave v.7.18c software was used for data acquisition and to 
close bottles on the rosette.  Real-time digital data were backed up onto Survey 
and PMEL networked PCs.  No real-time data were lost.

CTD deployments were initiated by the console watch after the ship had stopped 
on station. The watch maintained a CTD Cast log containing a description of each 
deployment, a record of every attempt to close a bottle, and any pertinent 
comments.

Once the deck watch had deployed the rosette, the winch operator would lower it 
to a minimum of 10 meters. The CTD sensor pumps were configured with a 60 second 
startup delay, and were usually on by this time. The console operator checked 
the CTD data for proper sensor operation, waited an additional 60 seconds for 
sensors to stabilize, instructed the winch operator to bring the package to the 
surface, pause for 10 seconds, and descend to a target depth. The profiling rate 
was nominally 30 m/min to 50 m, 45 m/min to 200 m, and 60 m/min deeper than 200 
m.  These rates varied depending on sea cable tension and the sea state.

The console watch monitored the progress of the deployment and quality of the 
CTD data through interactive graphics and operational displays.  Additionally, 
the watch created a sample log for the deployment that would be later used to 
record the correspondence between rosette bottles and analytical samples taken.  
The altimeter channel, CTD pressure, wire-out, pinger, and bathymetric depth 
were all monitored to determine the distance of the package from the bottom, 
usually allowing a safe approach to within 10 meters.

Bottles were closed on the up cast by operating an on-screen control, and were 
tripped 30 seconds after stopping at the trip location to allow the rosette wake 
to dissipate and the bottles to flush. The winch operator was instructed to 
proceed to the next bottle stop 10-20 seconds after closing bottles to ensure 
that stable CTD data were associated with the trip.  

After the last near-surface bottle was closed, the console operator directed the 
deck watch to bring the rosette on deck. Once on deck, the console operator 
terminated the data acquisition, turned off the deck unit and assisted with 
rosette sampling.

Normally the CTD sensors were rinsed after each station using syringes fitted 
with Tygon tubing and filled with a fresh solution of dilute Triton-X in de-
ionized water.  The syringes were generally left on the CTD between casts, with 
the temperature and conductivity sensors immersed in the rinsing solution, to 
guard against airborne contaminants.
Acquisition Problems

The CTD was initially connected to the aft winch, with a new termination on the 
0.375-inch single-conductor EM cable.  Test cast 998 produced three modulo 
errors.  Secondary temperature sensor s/n 4335 was lower than the primary by 
about 7°C throughout the profile.  The correct calibration coefficients were 
entered into the configuration file post-cast.  Secondary conductivity sensor 
s/n 3157 dropped out (to 0 kHz) around 3500 dbar on the downcast but came back 
around 3300 dbar on the upcast to within 0.002 mS/cm of the primary.  The 
secondary conductivity cable was replaced after the cast.  Also, the load cell 
was removed from the lifting bail because it appeared that the connector and 
cable could interfere with or even damage the carousel latches.  

While on the aft winch (stations 998,1-48), modulo errors occurred on each cast 
and numbered from 1 to 140. The number of errors increasing with wind speed and 
sea state.  Processed data had to be edited for spikes and gaps in various PTCO 
data channels.  In spite of repeated efforts, these modulo errors were never 
completely resolved.

Eventually the package was switched to the forward winch 0.322-inch three-
conductor cable for stations 49-72.  Modulo errors were few at first but 
increased to as many as 185 with choppier seas and level wind problems.  A 
broken strand in the outer armor of the winch cable was noticed at station 67.  
The protruding section was removed during station 67 and the ends were taped.  
All subsequent casts using the forward winch cable were stopped at 4268 m wire 
out to inspect the area and re-tape it if necessary.  During station 72 cast 1, 
communication was lost to the carousel.  The modem board in CTD s/n 315 was 
suspect, so it was replaced with CTD s/n 209.  Unfortunately, this didn't remedy 
the problem as expected and the package was moved to a new termination on the 
aft winch.

Modulo error counts were high on the aft winch (stations 72 cast 3 through 79 
cast 1).  Processed data had to be edited for spikes and gaps in any one of the 
PTCO data channels. Gaps and crossovers in the winch cable were discovered 
>5600m wire out as a possible source of noise and imbalance within the drum.  

Blown sea cable fuses in the deck unit owing to a faulty sea cable pigtail 
necessitated moving the package to a new termination on the forward winch.  This 
termination did not include the armor in the negative (ground) conductor.   
Profiles were successfully collected on this termination from station 79 cast 3 
to the end of the cruise with only occasional modulo errors.

The transmissometer worked intermittently between stations 1-16 in spite of 
troubleshooting efforts.  The cable was suspect and the instrument was removed 
from the underwater package for stations 17-18.  Since this had no effect on the 
modulo errors at that time, and since the instrument and cable tested OK in the 
lab, it was put back on the frame for station 19 and worked well thereafter for 
the most part.  Problem casts included stations 2, 5, 7, 10, 14, 16, 29, 31, 65-
69, and 70.

Oxygen voltage presented "pulses" in profiles from 2300 dbar to depth beginning 
at station 73 (CTD s/n 209).  The pulses occurred approximately every 200 dbar, 
were low by about 0.5 umol/kg, and lasted for 20-30 dbar.  Oxygen sensor s/n 312 
was replaced by s/n 313 after station 76.  The primary pump was replaced after 
station 77.  The oxygen cable was moved from V0 to V2 after station 78.  On V2, 
the pulses were more frequent but less pronounced, and were usually within 2500-
4000 dbar.  The oxygen cable was replaced after station 95.

The secondary plumbing air-bleed was clogged at station 32, affecting secondary 
conductivity data from 0-50 dbar.  After this cast, sensor differences were 
monitored closely at the beginning of each cast and the package was soaked at 50 
dbar if necessary.  The air-bleed was successfully cleared by station 36.


CTD Data Processing

The reduction of profile data began with a standard suite of processing modules 
using Sea-Bird Data Processing Version 7.19 software in the following order:

DATCNV     converts raw data into engineering units and creates a .ROS bottle 
           file.  Both down and up casts were processed for scan, elapsed 
           time(s), pressure, t0, t1, c0, c1, oxygen voltage, and oxygen.  
           Optical sensor data were converted to voltages and also carried 
           through the processing stream.  MARKSCAN was used to skip over scans 
           acquired on deck and while priming the system under water.
	
ALIGNCTD   aligns temperature, conductivity, and oxygen measurements in time 
           relative to pressure to ensure that derived parameters are made using 
           measurements from the same parcel of water.  Primary conductivity was 
           automatically advanced in the V1 deck unit by 0.073 seconds.  Primary 
           conductivity sensor s/n 3068 was aligned by -0.026 seconds in 
           ALIGNCTD for a net advance of 0.047 seconds.  Secondary conductivity 
           sensor s/n 3157 was advanced by 0.053 seconds in ALIGNCTD.  It was 
           not necessary to align temperature or oxygen.
	
BOTTLESUM  averages burst data over an 8-second interval (+/- 4 seconds of the 
           confirm bit) and derives both primary and secondary salinity, primary 
           potential temperature, and primary potential density anomaly.  Oxygen 
           values (in µmol/kg) were derived in DATCNV and averaged in BOTTLESUM, 
           as recommended recently by Sea-Bird.
	
WILDEDIT   makes two passes through the data in 100 scan bins.  The first pass 
           flags points greater than 2 standard deviations; the second pass 
           removes points greater than 20 standard deviations from the mean with 
           the flagged points excluded.  Data were kept within 100 standard 
           deviations of the mean (i.e. all data).
	
FILTER     applies a low pass filter to pressure with a time constant of 0.15 
           seconds.  In order to produce zero phase (no time shift) the filter 
           is first run forward through the file and then run backwards through 
           the file.
	
CELLTM     uses a recursive filter to remove conductivity cell thermal mass 
           effects from measured conductivity.  In areas with steep temperature 
           gradients the thermal mass correction is on the order of 0.005 PSS-
           78.  In other areas the correction is negligible.  Nominal values of 
           0.03 and 7.0 s were used for the thermal anomaly amplitude and the 
           thermal anomaly time constant, respectively, as suggested by Sea-
           Bird.
	
LOOPEDIT   removes scans associated with pressure slowdowns and reversals.  If 
           the CTD velocity is less than 0.25 m s-1 or the pressure is not 
           greater than the previous maximum scan, the scan is omitted.
	
DERIVE     uses 1-dbar averaged pressure, temperature, and conductivity to 
           compute primary and secondary salinity, as well as more accurate 
           oxygen.
	
BINAVG     averages the data into 1-dbar bins.  Each bin is centered on an 
           integer pressure value, e.g. the 1-dbar bin averages scans where 
           pressure is between 0.5 dbar and 1.5 dbar.  There is no surface bin.  
           The number of points averaged in each bin is included in the data 
           file.
	
STRIP      removes oxygen that was derived in DATCNV.
	
TRANS      converts the binary data file to ASCII format.


Package slowdowns and reversals owing to ship roll can cause density inversions 
and other artifacts.  In addition to Seasoft module LOOPEDIT, MATLAB program 
deloop.m computes values of density locally referenced between every 1 dbar of 
pressure to compute the square of the buoyancy frequency, N2, and linearly 
interpolates temperature, conductivity, and oxygen voltage over those records 
where N2 is less than or equal to -1 _ 10-5 s-2.  Seventeen profiles failed the 
criteria in the top 3-9 dbars.  These data were retained by program 
deloop_post.m and were flagged as questionable in the final WOCE formatted 
files.

Program calctd.m reads the delooped data files and applies calibrations to 
temperature, conductivity, and oxygen; and computes calibrated salinity.

Pressure Calibration

Pressure calibrations for the CTD instruments used during this cruise were pre-
cruise.  No additional adjustments were applied.  On deck pressure readings 
prior to each cast were examined and remained within 0.5 dbar of calibration.  
Differences between first and last submerged pressures for each cast were also 
examined and the residual pressure offsets were less than 0.5 dbar.  

Temperature Calibration

A viscous heating correction of -0.0006_C was applied at sea as recommended by 
Sea-Bird.  Post-cruise, a linearly interpolated temperature sensor drift 
correction using pre and post-cruise calibration data for the midpoint of the 
cruise was determined for each sensor, including the SBE 35 reference sensor.  
Viscous and drift corrections are applied to profile data using program 
calctd.m, and to burst data using calclo.m.

Data from the SBE 35 reference temperature sensor was evaluated post-cruise.   
Although there was some drift over the cruise (i.e. station dependence) and 
changes with pressure, these corrections were too small to apply.  The corrected 
primary temperature data are within about +/- 0.2 mK of the corrected reference 
sensor.

Conductivity Calibration

Seasoft module BOTTLESUM creates a sample file for each cast.  These files were 
appended using program sbecal.f.  Program addsal.f matched sample salinities to 
CTD salinities by station/sample number.  

For both conductivity sensors, stations were separated into three calibration 
groupings.  Program calcop2.m (a constant conductivity offset, a linear 
pressure-dependent correction to conductivity, and a 2nd order polynomial 
conductivity slope as a function of station number) produced the best fit to 
sample data for the primary conductivity sensor (s/n 3068) for the first two 
groupings.  Program calcop0.m (a constant conductivity offset, a linear 
pressure-dependent correction, and an overall slope) produced the best fit for 
the third grouping:

Conductivity calibrations were applied to profile data using program calctd.m 
and to burst data using calclo.m.  CTD-bottle conductivity differences plotted 
against station number (Figure 1) and pressure (Figure 2) allow a visual 
assessment of the success of the fits.

             Oxygen Calibration


A hybrid of the Owens-Millard (1985) and Murphy-Larson (revised 2010) oxygen 
sensor modeling equations was used to calibrate the SBE-43 oxygen sensor data 
from this cruise.  The equation has the form:

Ox=Soc*(V+Voff+Tau*exp(D1*P+D2*T)*dVdt)*Os*exp(Tcor*T)*exp(Pcor*P/(273.15+T))

Where:
    Ox is the CTD oxygen (in µmol/kg)
     V is the measured oxygen voltage (in volts)
  dVdt is the temporal gradient of the oxygen voltage (in volts/s estimated
       by running linear fits made over 5 seconds)
     P is the CTD pressure (in dbar)
     T is the CTD temperature (in C)
    Os is the oxygen saturation computed from the CTD data following
       Garcia & Gordon (1992).

Oxygen sensor hysteresis was improved by matching upcast bottle oxygen data to 
downcast CTD data by potential density anomalies referenced to the closest 1000-
dbar interval using program match_sgn.m.  We used the values provided by SBE for 
each sensor for the constants D1 (1.9263e-4) and D2 (-4.6480e-2) to model the 
pressure and temperature dependence of the response time for the sensor. For 
each group of stations fit we determined values of Soc (sometimes station 
dependent), Voff, Tau, Tcor, and Pcor by minimizing the residuals between the 
bottle oxygen and CTD oxygen.  Program addoxy.f matched bottle sample oxygen 
values to CTD oxygen values by station/sample number. Program 
run_oxygen_cal_ml.m was used to determine calibration coefficients for nine 
station groupings.  These groupings were determined by visual inspection:

Program interp_a13k.m was used to examine temperature, salinity, and oxygen 
profiles at 30 stations, despiking single points (WOCE quality flag 7) or 
interpolating over sections of bad data (WOCE quality flag 6) where needed.

Quality flags for sample salinities were amended from values determined at sea 
by viewing plots of calibrated CTD profiles and sample salinities generated by 
program plot_th_sa.m.  Similarly, recommendations for sample oxygens were 
forwarded to Chris Langdon after viewing plots of calibrated CTD/O2 profiles and 
sample oxygens generated by plot_pr_ox.m.

Program ctd_to_csv.m converted ASCII CTD data files to the WOCE Exchange format 
for submission to CCHDO.  The header information came from Mary Johnson's .SUM 
file dated June 4, 2010.  

Program clb_to_sea.m read calibrated CTD data associated with bottle data, and 
Mary Johnson's .SEA file dated June 2, 2010, and output an abbreviated .SEA file 
of CTD and flagged sample salinity data for submission to CCHDO.

Salinity Analysis

Equipment and Techniques

A single Guildline Autosal Model 8400B salinometer (S/N 61668), located in the 
aft Hydro lab, was used for all salinity measurements. The salinometer was 
connected to a computer to aid measurement. The Autosal's water bath temperature 
was set to 24°C, which the Autosal is designed to automatically maintain. The 
laboratory's temperature was also set and maintained to just below 24°C, to help 
further stabilize reading values and improve accuracy. As an additional 
safeguard the Autosal was powered through a UPS to prevent any power related 
issues.

Salinity analyses were performed after samples had equilibrated to laboratory 
temperature, usually within 12 to 24 hours after collection. The salinometer was 
standardized for each group of samples analyzed (usually 1.5-2.5 casts and up to 
65 samples) using two bottles of standard seawater: one at the beginning and end 
of each set of measurements. The salinometer output was logged to a computer 
file. The software prompted the analyst to flush the instrument's cell and 
change samples when appropriate. For each sample, the salinometer cell was 
initially flushed at least 3 times before a set of conductivity ratio readings 
were taken.

Standards

IAPSO Standard Seawater Batch P-147 was used to standardize all casts.

Sampling and Data Processing

Approximately 3000 salinity measurements were taken and approximately 140 vials 
of standard seawater (SSW) were used. A duplicate sample was drawn from each 
cast to determine total analytical precision. The salinity samples were 
collected in 200 ml Kimax high-alumina borosilicate bottles that had been rinsed 
at least three times with sample water prior to filling. The bottles were sealed 
with custom-made plastic insert thimbles and Nalgene screw caps. This assembly 
provides very low container dissolution and sample evaporation. Prior to sample 
collection, inserts were inspected for proper fit and loose inserts replaced to 
insure an airtight seal. Laboratory temperature was also monitored electronical-
ly throughout the cruise. PSS-78 salinity [UNES81] was calculated for each 
sample from the measured conductivity ratios. The offset between the initial 
standard seawater value and its reference value was applied to each sample. Then 
the difference (if any) between the initial and final vials of standard seawater 
was applied to each sample as a linear function of elapsed run time. The 
corrected salinity data was then incorporated into the cruise database. When 
duplicate measurements were deemed to have been collected and run properly they 
were averaged and submitted with a quality flag of '6'.

Equipment and Techniques

Dissolved oxygen analyses were performed with an automated titrator using 
amperometric end-point detection [Culberson, 1987]. Sample titration , data 
logging, and graphical display were performed with a PC running a LabVIEW 
program written by Ulises Rivero of AOML.  Lab temperature was maintained at 
18.5-22.5°C. Thiosulfate was dispensed by a 2 ml Gilmont syringe driven with a 
stepper motor controlled by the titrator.  Tests in the lab were performed to 
confirm that the precision and accuracy of the volume dispensed were comparable 
or superior to the Dosimat 665. The whole-bottle titration technique of 
Carpenter [1965], with modifications by Culberson et al. [1991], was used.  Four 
replicate 10 ml iodate standards were run every 3-4 days.  The reagent blank 
determined as the difference between V1 and V2, the volumes of thiosulfate 
required to titrate 1-ml aliquots of the iodate standard, was determined five 
times during the cruise. This method was found during pre-cruise testing to 
produce a more reproducible blank value than the value determined as the 
intercept of a standard curve.  The temperature-corrected molarity of the 
thiosulfate titrant was determined as given by Dickson [1994].

Sampling and Data Processing

Dissolved oxygen samples were drawn from Niskin bottles into calibrated 125-150 
ml iodine titration flasks using silicon tubing to avoid contamination of DOC 
and CDOM samples. Bottles were rinsed three times and filled from the bottom, 
overflowing three volumes while taking care not to entrain any bubbles.  The 
draw temperature was taken using a digital thermometer with a flexible 
thermistor probe that was inserted into the flask while the sample was being 
drawn during the overflow period. These temperatures were used to calculate 
umol/kg concentrations, and provide a diagnostic check of Niskin bottle 
integrity.  1 ml of MnCl2 and 1 ml of NaOH/NaI were added immediately after 
drawing the sample was concluded using a Re-pipetor. The flasks were then 
stoppered and shaken well. DIW was added to the neck of each flask to create a 
water seal.  24 samples plus two duplicates were drawn from each station. The 
total number of samples collected from the rosette was 3341.

The samples were stored in the lab in plastic totes at room temperature for 1.5 
hours before analysis. The data were incorporated into the cruise database 
shortly after analysis.

Thiosulfate normalities were calculated from each standardization and corrected 
to the laboratory temperature.

Volumetric Calibration

The dispenser used for the standard solution (SOCOREX Calibrex 520) and the 
burette were calibrated gravimetrically just before the cruise.  Oxygen flask 
volumes were determined gravimetrically with degassed deionized water at AOML. 
The correction for buoyancy was applied. Flask volumes were corrected to the 
draw temperature.

Duplicate Samples

A total of 172 sets of duplicates were run. The average standard deviation of 
all sets was 0.18 umol/kg.

Problems

Three oxygen flasks were removed and replaced with different flasks during the 
cruise, after giving consistently high values.  Duplicates were collected using 
each questionable flask and analyzed; if the values differed significantly, the 
flask was removed.  The following flasks were tested and replaced:

NUTRIENTS

Nutrient samples were collected from the Niskin bottles in acid-washed sample 
bottles after at least three seawater rinses.  Sample analysis typically began 
within 1 hour of sample collection after the samples had warmed to room 
temperature while kept in the dark.  Nutrients were analyzed with a continuous 
flow analyzer (CFA) using the standard and analysis protocols for the WOCE 
hydrographic program as set forth in the manual by L.I. Gordon, et al. 

Analytical Methods

3049 samples were taken at discrete depths and analyzed for phosphate (PO4_ 3), 
nitrate (NO3_), nitrite (NO2_) and orthosilicic acid (H4SiO4).  Nitrite was 
determined by diazotizing the sample with sulfanilamide and coupling with N-1 
naphthyl ethylenediamine dihydrochloride to form an azo dye.  The color produced 
is measured at 540 nm.  Samples for nitrate analysis were passed through a 
cadmium column, which reduced nitrate to nitrite, and the resulting nitrite 
concentration (i.e. the sum of nitrate + nitrite which is signified as N+N) was 
then determined as described above. Nitrate concentrations were determined from 
the difference of N+N and nitrite.  Phosphate was determined by reacting the 
sample with molybdic acid at a temperature of 55°C to form phosphomolybdic acid.  
This complex was subsequently reduced with hydrazine, and the absorbance of the 
resulting phosphomolybdous acid was measured at 820 nm. Silicic acid was 
analyzed by reacting the sample with molybdate in an acidic solution to form 
molybdosilicic acid. The molybdosilicic acid was then reduced with SnCl2 to form 
molybdenum blue. The absorbance of the molybdenum blue was measured at 820 nm. 

A typical analytical run consisted of distilled water blanks, standard blanks, 
working standards, a standard from the previous run, a deep sample from the 
previous run, samples, replicates, working standards, and standard and distilled 
water blanks. Replicates were usually run for the 4-7 deepest Niskin bottles 
from each cast, plus any samples with questionable peaks. The standard deviation 
of the deep replicates was used to estimate the overall precision of the method 
which was <1% full scale.

Analytical precision and the measured nutrient content in deep water were 
similar to the AJAX cruise in 1983.  Significant offsets in oxygen, nitrate and 
phosphate were observed compared to the 1993 Discovery cruise.  

Temperatures in the ship's main laboratory fluctuated with temperatures ranging 
from 18.7°C to 25.5°C; however, temperatures were generally stable during an 
individual analytical run.  During the cruise, pump tubes were changed about 3 
times per channel as needed.

Standardization

A mixed stock standard consisting of silicic acid, phosphate and nitrate was 
prepared by dissolving high purity standard materials (KNO3, KH2PO4 and Na2SiF6) 
in deionized water using a two step dilution for phosphate and nitrate. This 
standard was stored at room temperature. A nitrite stock standard was prepared 
about every 10 days by dissolving NaNO2 in distilled water, and this standard 
was stored in the refrigerator. Working standards were freshly made at each 
station by diluting the stock solutions in low nutrient seawater. Mixed 
standards were verified against commercial standards purchased from Ocean 
Scientific. 

Problems

Due to problems with the Alpkem 301 sampler, a Westco CS9000 sampler, with 20 ml 
plastic sample bottles, was used on Stations 3 to 9.  There was not enough 
volume in these sample bottles for sample reruns.  During these stations, there 
was unnoticed algal build-up in the sample lines that was coincident with 
increased analytical variability.  On Station 10, the Alpkem sampler was back in 
use, and all the sample lines were changed.  Thereafter, sample lines were 
rinsed with 10% HCl between runs.  

On Station 99, the nitrate peaks became very erratic.  Several stations were 
analyzed before it could be determined that the ship's water was the source of 
the problem.  Several batches of Imidazole were made from various sources of 
water on the ship, but Cd column had very low efficiencies.  Instead of 
Imidazole, we used Low Nutrient Seawater as a buffer for Stations 101 to 104.  
The column efficiency was not completely stable during these runs, so we reran 
about half of each cast and found the precision to be ~1.5%. To stabilize the 
column, we added 1 ml CuSO4 to 1200ml LNSW beginning at Station 105.  For the 
remainder of the cruise, the column efficiency varied between ~80-100 percent 
(determined at the end of each run); however, the efficiency was stable for each 
individual run.  

On Station 46, an offset occurred during the final standard analysis, and 
despite having numerous replicate samples, a correction could not be determined 
and the data was flagged as questionable.

CFCs and SF6
David Wisegarver, PMEL; Patrick Boylan, U, Colorado; Ivy Frenger, ETH
(PI: John Bullister, PMEL)


A PMEL analytical system (Bullister and Wisegarver, 2008) was used for CFC-11, 
CFC-12,  and sulfur hexafluoride (SF6) analyses on the CLIVAR A13.5 expedition.  
About 2800 seawater samples were analyzed for dissolved CFC-11, CFC-12 and SF6 
('CFC/SF6') concentrations. On some casts, the analysis was modified to include 
the analysis of nitrous oxide (N2O) or carbon tetrachloride. These N2O and 
carbon tetrachloride analyses were done as part of an experimental study to try 
to develop more reliable methods for measuring these compounds in seawater on 
future CLIVAR cruises, and are not included in the data report.

In general, the analytical system performed well.  Typical dissolved SF6 
concentrations in modern surface water are ~1 fmol kg-1 seawater (1 fmol= 
femtomole = 10-15 moles), approximately 1000 times lower than dissolved CFC-11 
and CFC-12 concentrations.  The limits of detection for SF6 on CLIVAR A13.5 were 
approximately 0.02 fmol kg-1.  SF6 measurements in seawater remain extremely 
challenging. Improvements in the analytical sensitivity to this compound at low 
concentrations are essential to make these measurements more routine on future 
CLIVAR cruises. 
 
Water samples on CLIVAR A13.5 were collected in bottles designed with a modified 
end-cap to minimize water contact with the end-cap O-rings after closing.  
Stainless steel springs covered with a nylon powder coat were substituted for 
the internal elastic tubing provided with standard Niskin bottles. When taken, 
water samples collected for dissolved CFC-11, CFC-12, and SF6 analysis were the 
first samples drawn from the bottles. Care was taken to coordinate the sampling 
of CFC/SF6 with other samples to minimize the time between the initial opening 
of each bottle and the completion of sample drawing. Samples easily impacted by 
gas exchange (dissolved oxygen, 3He, DIC and pH) were collected within several 
minutes of the initial opening of each bottle. To minimize contact with air, the 
CFC/SF6 samples were drawn directly through the stopcocks of the bottles into 
250 ml precision glass syringes equipped with three-way plastic stopcocks. The 
syringes were immersed in a holding tank of clean surface seawater held at ~10°C 
until ~20 minutes before being analyzed.  At that time, the syringe was place in 
a bath of surface seawater heated to ~30°C.

For atmospheric sampling, a ~75 m length of 3/8" OD Dekaron tubing was run from 
the CFC van located on the fantail to the bow of the ship. A flow of air was 
drawn through this line into the main laboratory using an Air Cadet pump. The 
air was compressed in the pump, with the downstream pressure held at ~1.5 atm. 
using a back pressure regulator. A tee allowed a flow of ~100 ml min-1 of the 
compressed air to be directed to the gas sample valves of the CFC/SF6 analytical 
systems, while the bulk flow of the air (>7 l min-1) was vented through the 
back-pressure regulator. Air samples were analyzed only when the relative wind 
direction was within 60 degrees of the bow of the ship to reduce the possibility 
of shipboard contamination.  Analysis of bow air was performed along the cruise 
track. At each location, at least five air measurements were made to determine 
the precision of the measurements.

Concentrations of CFC/SF6 in air samples, seawater, and gas standards were 
measured by shipboard electron capture gas chromatography (EC-GC) using 
techniques modified from those described by Bullister and Weiss (1988) and 
Bullister and Wisegarver (2008) as outlined below.  For seawater analyses, water 
was transferred from a glass syringe to a glass-sparging chamber (volume ~200 
ml). The dissolved gases in the seawater sample were extracted by passing a 
supply of CFC/SF6 free purge gas through the sparging chamber for a period of 6 
minutes at ~150 ml min-1. Water vapor was removed from the purge gas during 
passage through an 18 cm long, 3/8" diameter glass tube packed with the 
desiccant magnesium perchlorate. The sample gases were concentrated on a cold-
trap consisting of a 1/16" OD stainless steel tube with a 2.5 cm section packed 
tightly with Porapak Q (60-80 mesh), a 22 cm section packed with Carboxen 1000, 
and a 2.5 cm section packed with molecular sieve MS5A.  A Neslab Cryocool CC-100 
was used to cool the trap to ~-70°C.  After 6 minutes of purging, the trap was 
isolated, and it was heated electrically to ~160°C. The sample gases held in the 
trap were then injected onto a precolumn (~60 cm of 1/8" O.D. stainless steel 
tubing packed with 80-100 mesh Porasil B, held at 80°C) for the initial 
separation of CFC-12, CFC-11 and SF6  from later eluting peaks.

After the SF6 and CFC-12 had passed from the pre-column and into the second 
precolumn (5 cm of 1/8" O.D. stainless steel tubing packed with MS5A, 90°C) and 
into the analytical column #1 (240 cm of 1/8" OD stainless steel tubing packed 
with MS5A and held at 80°C), the outflow from the first precolumn was diverted 
to the second analytical column (150 cm 1/8" OD stainless steel tubing packed 
with Carbograph 1AC, 80-100 mesh, held at 90°C). After CFC-11 had passed through 
the first pre-column, the flow was diverted to a third analytical column (1.7 m, 
Carbograph 1AC, 90°C). The gases remaining after CCl4 had passed through the 
first pre-column, were backflushed from the pre-column and vented. Column #1 and 
the first pre-column were held in a Shimadzu GC8 gas chromatograph with an 
electron capture detector (ECD) held at 340°C. Column #2, column #3 and the 
second precolumn were in another Shimadzu GC8 gas chromatograph with ECD. The 
output from column #3 was plumbed to a Shimadzu Mini2 gas chromatograph with the 
ECD held at 250°C.  This was done because the temperature stability of the Mini2 
controller was not adequate for this analysis.  On the stations in which nitrous 
oxide was analyzed, the content of the second precolumn was directed to column 
#3.  This prevented the analysis of carbon tetrachloride on those samples.

The analytical system was calibrated frequently using a standard gas of known 
CFC/SF6 composition. Gas sample loops of known volume were thoroughly flushed 
with standard gas and injected into the system.  The temperature and pressure 
was recorded so that the amount of gas injected could be calculated. The 
procedures used to transfer the standard gas to the trap, precolumn, main 
chromatographic column, and ECD were similar to those used for analyzing water 
samples. Four sizes of gas sample loops were used. Multiple injections of these 
loop volumes could be made to allow the system to be calibrated over a 
relatively wide range of concentrations. Air samples and system blanks 
(injections of loops of CFC/SF6 free gas) were injected and analyzed in a 
similar manner. The typical analysis time for seawater, air, standard or blank 
samples was ~11 minutes.

Concentrations of CFC-11 and CFC-12  in air, seawater samples, and gas standards 
are reported relative to the SIO98 calibration scale (Cunnold et al., 2000). 
Concentrations of SF6 in air, seawater samples, and gas standards are reported 
relative to the SIO2005 calibration scale. Concentrations of CFC/SF6 in air and 
standard gas are reported in units of mole fraction CFC/SF6 in dry gas, and are 
typically in the parts per trillion (ppt) range. Dissolved CFC concentrations 
are given in units of picomoles per kilogram seawater (pmol kg-1) and SF6 
concentrations in fmol kg-1.  CFC/SF6 concentrations in air and seawater samples 
were determined by fitting their chromatographic peak areas to multi-point 
calibration curves, generated by injecting multiple sample loops of gas from a 
working standard (PMEL cylinder 72611) into the analytical instrument. The 
response of the detector to the range of moles of CFC/SF6 passing through the 
detector remained relatively constant during the cruise. Full-range calibration 
curves were run at intervals of 4-5 days during the cruise. Single injections of 
a fixed volume of standard gas at one atmosphere were run much more frequently 
(at intervals of ~90 minutes) to monitor short-term changes in detector 
sensitivity.

The purging efficiency was estimated by re-purging a high-concentration water 
sample and measuring this residual signal.  At a flow rate of 150 cc min-1 for 6 
minutes, the purging efficiency for CFC-11, CFC-12 and SF6 was about 99% or 
higher. 

On this expedition, based on the analysis more than 200 pairs of duplicate 
samples, we  estimate precisions (1 standard deviation) of about 1% or 0.002 
pmol kg-1(whichever is greater) for both dissolved CFC-11 and CFC-12  
measurements.  The estimated precision for SF6 was 2% or 0.02 fmol kg-1 
(whichever is greater).  Overall accuracy of the measurements (a function of the 
absolute accuracy of the calibration gases, volumetric calibrations of the 
sample gas loops and purge chamber, errors in fits to the calibration curves and 
other factors) is estimated to be about 2% or 0.004 pmol kg-1 for CFC-11 and 
CFC-12 and 4% or 0.04 fmol kg-1 for SF6.

A small number of water samples had anomalously high CFC/SF6 concentrations 
relative to adjacent samples. These samples occurred sporadically during the 
cruise and were not clearly associated with other features in the water column 
(e.g., anomalous dissolved oxygen, salinity, or temperature features). This 
suggests that these samples were probably contaminated with CFCs/SF6 during the 
sampling or analysis processes.
Measured concentrations for these anomalous samples are included in the data 
file, but are given a quality flag value of either 3 (questionable measurement) 
or 4 (bad measurement).  Less than 2% of samples were flagged as bad or 
questionable during this voyage.  A quality flag of 5 was assigned to samples 
which were drawn from the rosette but never analyzed due to a variety of reasons 
(e.g., leaking stopcock, plunger jammed in syringe barrel, etc).

DISSOLVED INORGANIC CARBON (DIC)
Cynthia Peacock, PMEL; Alex Kozyr, CDIAC
(PIs: Richard Feely, PMEL; Rik Wanninkhof, AOML)


The DIC analytical equipment was set up in a seagoing container modified for use 
as a shipboard laboratory. The analysis was done by coulometry with two 
analytical systems (PMEL-1 and PMEL-2) used simultaneously on the cruise.  Each 
system consisted of a coulometer (UIC, Inc.) coupled with a SOMMA (Single 
Operator Multiparameter Metabolic Analyzer) inlet system developed by Ken 
Johnson (Johnson et al., 1985, 1987, 1993; Johnson, 1992) of Brookhaven National 
Laboratory (BNL).  In the coulometric analysis of DIC, all carbonate species are 
converted to CO2 (gas) by addition of excess hydrogen to the seawater sample. 
The evolved CO2 gas is carried into the titration cell of the coulometer, where 
it reacts quantitatively with a proprietary reagent based on ethanolamine to 
generate hydrogen ions.  These are subsequently titrated with coulometrically 
generated OH-. CO2 is thus measured by integrating the total charge required to 
achieve this.

The coulometers were each calibrated by injecting aliquots of pure CO2 (99.995%) 
by means of an 8-port valve outfitted with two sample loops (Wilke et al., 
1993).  The instruments were calibrated at the beginning of each station with 
two sets of the gas loop injections.

Secondary standards were run throughout the cruise (at least one per station) on 
each analytical system. These standards are Certified Reference Materials 
(CRMs), consisting of poisoned, filtered, and UV irradiated seawater supplied by 
Dr. A. Dickson of Scripps Institution of Oceanography (SIO). Their accuracy is 
determined shoreside manometrically.  DIC data reported to the database have 
been corrected to the batch 98 CRM value.

Samples were drawn from Niskin-type bottles into cleaned, precombusted 300-mL 
Pyrex bottles using silicon tubing. Bottles were rinsed once and filled from the 
bottom, overflowing half a volume. Care was taken not to entrain any bubbles. 
The tube was pinched off and withdrawn, creating a 5-mL (2%) headspace, and 
0.122 mL of 50% saturated HgCl2 solution was added as a preservative. The sample 
bottles were sealed with glass stoppers lightly covered with Apiezon-L grease, 
and were stored in a 20°C water bath for a minimum of 20 minutes to bring them 
to temperature prior to analysis.

Over 3000 samples were analyzed for discrete DIC. Full profiles were completed 
at almost every station. Replicate samples were taken from the surface, oxygen 
minimum, and bottom bottles.  Occasionally duplicates were not taken, due to 
high water use with other chemical analyses (determined by the chief scientist).  
The replicate samples were interspersed throughout the station analysis for 
quality assurance and integrity of the coulometer cell solutions. 
DIC measurements were performed by Cynthia Peacock (lead) from the University of 
Washington, Joint Institute for the Study of the Atmosphere and Ocean (JISAO), a 
contractor for the National Oceanic and Atmospheric Administration (NOAA), 
Pacific Marine Environmental Laboratory (PMEL); and Alex Kozyr, from the Carbon 
Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory.

A total of over 400 pure (99.995%) CO2 gas calibrations were run on both SOMMA 
systems during this cruise.  The precision and accuracy obtained from these 
calibrations can be described as follows:

1. The precision is estimated from ~300 replicate pairs.
   The absolute average difference from the mean of these replicates is 0.62 
   µmol/kg. No significant systematic differences were noted.
2. The accuracy is estimated from the analysis of 120 Certified Reference 
   Materials (batch 98). The CRM value is 2013.85 µmol/kg. Our average value was 
   2011.7 µmol/kg with a standard deviation of 1.3 µmol/kg.

ALKALINITY

Samples were taken from all Niskin bottles. After thorough rinsing, samples were 
collected in 250 ml Pyrex serum bottles. Approximately 0.06 milliliters of a 
saturated mercuric chloride solution were added to each sample. A headspace of 
approximately 5ml was left for stations 001-069. This was increased to ~20ml for 
stations 070-129. 

Starting at station 008 samples were allowed to equilibrate (using a heater for 
the coldest) until near 20 degrees Celsius. Stations 001-008 were not allowed to 
properly equilibrate.

Samples of volume 99.9 ml were dispensed using a Metrohm 765 Dosimat with a 50 
ml burette. The temperature of the samples at time of dispensing was taken using 
a YSI 4600 thermometer, to convert this volume to mass for analysis. For some 
number of samples, bubbles formed in the burette, most likely displacing volume. 
This was especially a problem on stations 050-070. By allowing the samples to 
degas, using a larger headspace and vigorous shaking, most bubbles were avoided 
after Station 070. One large bubble, displacing sample volume, causes an 
approximate error of 2 umol/kg lower alkalinity. 

Samples were analyzed using an open beaker titration procedure using two 
thermostated beakers; one sample being titrated while the second was being 
prepared and equilibrating to the system temperature of 20 degrees C. After an 
initial aliquot of approximately 2.5 mls of standardized hydrochloric acid 
(~0.1Molar HCl in ~0.6M NaCl solution), the sample was stirred for approximately 
5 minutes to remove liberated carbon dioxide. The stir time has been minimized 
by bubbling carbon dioxide free air into the sample. After equilibration, 18 
aliquots of 0.05 mls were added. The data within the pH range of 3.5 to 3.0 were 
processed using a non-linear least squares fit from which the alkalinity value 
of the sample was calculated (Dickson, et. al., 2007). 

Dickson laboratory Certified Reference Materials (CRM) Batch B98 was used to 
estimate the accuracy of the analysis.

Usually two duplicates, surface and deep were taken, but sometimes a third 
duplicate at the oxygen minimum was also analyzed. Occasionally when limited by 
sample water, only one, or no duplicates were taken.  Throughout the cruise, 
approximately 250 duplicates were analyzed. The pooled standard deviation was 
1.4 (mol kg-1.

The data should be considered preliminary since the correction for the 
difference between the CRMs stated and measured values has yet to be finalized 
and applied. Most likely this correction will be significant for part of the 
data, as a shift was seen in CRM values at several points throughout the cruise, 
most notably at Station 062. At this point it was necessary to change to the 
backup sample dispensing burette and it seems this shifted the CRM value down 
for a time. 

Additionally, the correction for the mercuric chloride addition has yet to be 
applied. As part of the data evaluation, a determination was made for the 
possible contribution of the mercuric chloride to the alkalinity. The data 
indicate no contribution, either positive or negative, from the mercuric 
chloride.

fCO2 (discrete)
Kevin Sullivan, AOML; Geun-Ha Park, AOML)
(PI: Rik Wanninkhof, AOML)


Samples were drawn from the Niskin bottles into 500 ml volumetric flasks for 
measurement of the fugacity of the dissolved carbon dioxide (fCO2).  The samples 
were drawn using a Tygon(c) tube with a short length of silicone tubing to fit 
over the petcock to avoid contamination of CDOM samples.  The flasks were rinsed 
while inverted and then filled from the bottom, overflowing half a volume while 
taking care not to entrain any bubbles.  About 5 ml of water was withdrawn with 
a pipette to allow for expansion of the water as it warms and to provide space 
for the stopper, tubing, and frit of the analytical system.   Mercuric chloride 
solution (0.244 ml at half-saturation) was added as a preservative.  The sample 
flasks were sealed with a screw cap containing a polyethylene liner. The samples 
were stored in coolers at air-conditioned room temperature generally for no more 
than 4 hours.

The relatively time-consuming analyses would not permit samples to be drawn from 
all Niskins at all stations.  For the majority of the stations, twenty six 
flasks were drawn on the twenty four Niskins.  Two pairs of duplicate flasks 
were drawn on most casts.  Until the station spacing was shortened near the 
equator, a partial cast of sixteen or eighteen flasks was drawn about every 
fourth station.  Across the equator and to the end of the cruise, full and 
partial cast were alternated.  The number of flasks in the partial cast was 
adjusted to avoid a large backlog of samples.

All analyses were done at 20°C.  A secondary bath was used to get the samples 
close to the analytical temperature prior to analysis.  As soon as space was 
available in the secondary or primary bath, sample flasks were moved into the 
more controlled temperature bath.  No flask was analyzed without spending at 
least 1.5 hours in these water bathes.

The discrete fCO2 system is patterned after the instrument described in Chipman 
et al. (1991) and is discussed in detail in Wanninkhof and Thoning (1993) and 
Chen et al. (1995).  The major difference between the two systems is that the 
Wanninkhof and current instrument uses a LI-COR(c) model 6262 non-dispersive 
infrared analyzer, while the Chipman instrument utilizes a gas chromatograph 
with a flame ionization detector.

Once the samples reach the analytical temperature, a ~50-ml headspace is created 
by displacing the water using a compressed standard gas with a CO2 mixing ratio 
close to the anticipated fCO2 of the water.  The headspace is circulated in a 
closed loop through the infrared analyzer that measures CO2 and water vapor 
concentrations.  The samples are equilibrated until the running mean of 20 
consecutive 1-second readings from the analyzer differ by less than 0.1 ppm 
(parts per million by volume).  This equilibration takes about 10 minutes.  An 
expandable volume in the circulation loop near the flask consisting of a small, 
deflated balloon keeps the headspace of the flask at ambient pressure.

In order to ensure analytical accuracy, a set of six gas standards is run 
through the analyzer before and after every eight seawater samples. (cylinder 
serial numbers CA5998 [205.07 ppm], CA5989 [378.71 ppm], CA5988 [593.64 ppm], 
CA5980 [792.51 ppm], CA5984 [1036.95 ppm], and CA5940 [1533.7 ppm])

The standards were obtained from Scott-Marin and referenced against primary 
standards purchased from C.D. Keeling in 1991, which are on the WMO-78 scale.

The calculation of fCO2 in water from the headspace measurement involves several 
steps.  The CO2 concentrations in the headspace are determined via a second-
degree polynomial fit using the nearest three standard concentrations.  
Corrections for the water vapor, the barometric pressure, and the changes 
induced in the carbonate equilibrium by the mass transfer of CO2 in or out of 
the water sample are made.  The corrected results are reported at a reference 
temperature of 20.00°C.

At the beginning of the cruise one of the gas circulation channels was 
performing at an acceptable, though not optimal flow rate.  The equilibrations 
were requiring more time than in the other channel.  Efforts were made over two 
days to improve the flow rate in the slow channel.  The flows improved 
significantly after station 41.  With continuous use of the pumps, excellent 
flows developed starting at station 50.

During the analyses of station 45, the temperature of the water bath began to 
drift.  After some efforts to stabilize the temperature, the water bath was 
replaced.  One pair of samples was lost, and the analyses of most of the samples 
from station 45 were delayed an additional 4 hours.  Because of the delay, no 
samples were collected on station 46. 

There were 183 pairs of duplicate samples drawn from Niskins on 101 stations.  
The average relative difference between all the pairs was 0.250 % (+/- 0.287 %).

             (bottom).  While the overall patterns are similar for the two 
             cruises that are 26 years apart, increases of fCO2(20) in bottom 
             water and in the intermediate water formation areas are apparent. 
             The contours in the top panel were smoothed because of a five-fold

The standards were obtained from Scott-Marin and referenced against primary 
standards purchased from C.D. Keeling in 1991, which are on the WMO-78 scale.  

The mass transfer of CO2 in or out of a water sample during analysis induces a 
change in the carbonate equilibrium affecting the DIC and fCO2 but not the TAlk.  
The analytical results for other parameters (DIC, phosphate, and silicate) from 
the same Niskin are used in calculations to correct for this small change.  If 
any of these parameters are missing or flagged as questionable (QF= 3) or bad 
(QF= 4), a value consistent with the surrounding data is assigned.  This 
assignment of the auxiliary parameters was done for thirty-six CO2 analyses that 
were flagged as good (QF = 2).  The assignment of values was rarely necessary 
for the CTD salinity and potential temperature, which were also used in 
producing the final result.  Analyses were performed at an accurately measured 
temperature of nominally 20˚C. Small adjustments to 20.00˚C were performed using 
the temperature coefficients of the carbonate dissociation constants.  The final 
result is the fugacity of CO2 at a reference temperature of 20°C, fCO2(20).

The fCO2(20) was plotted as vertical profiles and as sections at discrete 
pressure intervals versus latitude.   The pressure intervals used were: 5-51 dB, 
59-153 dB, 160-550 dB, 574-1552 dB, 1598-3537 dB, and 3350-5800 dB.  Anytime an 
appreciable anomaly was observed the fCO2(20), TAlk, pH, and DIC were 
scrutinized to assess if the fCO2(20) should be flagged.

In addition to the examination of the fCO2 analyses in its spatial context, an 
examination of the fCO2 analyses for internal consistency within the carbonate 
equilibrium chemistry was done.  For this check, fCO2(20) was calculated from 

(a) DIC and TAlk,  referred to as fCO2(DIC,TA) and 
(b) DIC and pHT(20) (= pH on total scale at 20˚C),  referred to as fCO2(DIC,pH) 

using the CO2sys macro in Excel developed by Pierrot based on the original BASIC 
program of Lewis and Wallace.  Salinity, silicate, and phosphate as provided in 
the bottle data file were used as auxiliary parameters.  The calculations were 
performed with the carbonic acid dissociation constants of Mehrbach as refit by 
Dickson and Millero, and the sulfate dissociation constant from Dickson. Note 
that the Alkalinity and pH values were the preliminary ship-based values.  These 
two fCO2(20) values were only calculated if the DIC, TAlk, and pH measurements 
were flagged as good (QF=2).  Anomalous differences drew scrutiny.

The differences between the analytical fCO2(20) and the two calculated fCO2(20) 
values are summarized.

                                         Avg Difference  StdDev 
                                             (µatm)      (µatm)
                -----------------------  --------------  ------
                fCO2(20) - fCO2(DIC,TA)      -14.06       26.68
                fCO2(20) - fCO2(DIC,pH)       11.86        6.17


From these examinations, twenty-two Niskins associated with outlying fCO2 
analyses were identified as likely miss-trips.  Seven of these fCO2 analyses are 
flagged as bad (QF=4); fifteen are flagged as questionable (QF=3).  Two of the 
fifteen questionable values were actually averages of duplicate samples (Stn# 
79, N# 15 and Stn# 103, N# 5).  The duplicates are included in the precision 
statistics reported below, since the placement of the Niskin in the water column 
does not matter to the reproducibility of the sample draw and analysis.

There were fifteen fCO2 analyses that were outliers from Niskins that were not 
likely miss-trips.  Eleven of these analyses are flagged as bad; nine are 
flagged as questionable.  There was one sample from a duplicate pair that was an 
outlier, so the other samples was reported and flagged as good (QF=2).  The 
decision whether an fCO2 analysis was bad or questionable was based on how 
inconsistent the value was relative to the surrounding data.  The contextual QC 
check was done by Kevin Sullivan; additional contextual and the internal 
consistency QC checks were done by Rik Wanninkhof.

There were 183 pairs of duplicate samples drawn from Niskins on 101 stations.  
The average relative difference between all the pairs was 0.250 % (+/- 0.287 %).  
If the four relative differences above 1% are excluded (~95% confidence 
interval), the average relative difference was 0.220 % (+/- 0.209 %).

fCO2 (underway)
Kevin Sullivan, AOML
(PI: Rik Wanninkhof, AOML)


An automated underway fCO2 system from AOML has been situated in the hydro lab 
of the R/V Ronald H. Brown since it was commissioned in July 1997.  The current 
system has been aboard since September, 2008, and is a model 8050 from General 
Oceanics, Inc (GO).  Access to the data can be found at AOML's global carbon 
cycle web page (http://www.aoml.noaa.gov/ocd/gcc/rvbrown_introduction.php).

Early instrument designs are discussed in Wanninkhof and Thoning (1993) and in 
Feely et al. (l998).  The current design as well as the data processing 
procedure is detailed in Pierrot et al. (2009).

Seawater continuously flows through a closed equilibration chamber at 
approximately 2 liters/minute.  A spiral nozzle creates a conical spray that 
enhances the gas exchange with the enclosed gaseous headspace.  During 'water' 
analyses this overlying headspace is pushed through an infrared analyzer and 
returned to the equilibrator.  During air analyses, outside air is pulled from 
an inlet on the forward mast and pushed through the analyzer.  The pressure and 
temperature inside the equilibrator are constantly being measured.  With 
knowledge of the sea-surface temperature and salinity, along with all the 
parameters measured by the system, one can calculate the fugacity of CO2 in the 
seawater and the atmosphere above it.

To ensure the accuracy of analyzer output, every 2.6 hours four standard gases 
are analyzed.  (serial numbers CA06709 [284.75 ppm], CA02813 [363.24 ppm], 
CA07921 [423.57 ppm], and CA07931 [545.88 ppm])  They were purchased from 
NOAA/ESRL in Boulder, CO and are directly traceable to the WMO scale.  After the 
standards, five air analyses and then fifty water analyses are done.  With 
continuous operation, the current system provides over 920 water analyses per 
day.  During this cruise, the operation was interrupted while the ship was 
maintaining station several times for testing and upgrades.

The first upgrade was done before the ship left Cape Town.  A new equilibrator 
with a water jacket was installed.  The new equilibrator has a seawater flow of 
approximately 1.5 liters/minute flowing through a concentric enclosure around 
the vertical walls.  This thermal insulation improves the stability and accuracy 
of the temperature measured in the main equilibrator, especially with very cold 
waters.

Additional upgrades were associated with the firmware and software used to 
control the hardware.  On 12 March 2010, a new version of the software was 
installed and worked well.  On 2 April 2010, a new firmware and the necessary 
software were installed.  These upgrades yielded a more stable and adaptable 
analytical system.  On 9 April 2010 the GPS signal was switched from the 
dedicated deck box that comes with the GO system to the ship's GPS that is 
broadcast through the ship.

Other than these planned service events, the system ran continuously during the 
entire cruise.  Preliminary examinations of the data confirm good analyses.  
Calculation of final values of fugacity will require some time given the volume 
of data.

During this cruise approximately 3300 water samples were analyzed from rosette 
casts at 129 stations and 1 test station.  Samples were analyzed using the 
method described in Dickson et al [2007]  Analyses were made with an Agilent 
8453 spectrophotometer equipped with a 10 cm jacketed flow cell using the 
sulfonephthalein indicator  m-cresol  purple (mCP). Sample introduction to the 
cell and dye addition were automated using a Kloehn V6 syringe pump. Results are 
reported on the total hydrogen ion scale at XX°C .

All stations were sampled on the cruise, and the sampling scheme was to sample 
every bottle where an alkalinity or total carbon measurement was taken in order 
to generate a complete characterization of the carbon system.  This resulted in 
full coverage of all tripped bottles.  Samples were drawn from Niskin bottles on 
the rosette using silicone tubing into 300 mL Pyrex glass serum bottles.  The 
serum bottles were rinsed three times, filled and allowed to overflow by one 
additional bottle volume.  The samples were poisoned with 0.02% saturated HgCl2 
solution and capped with a rubber stopper without allowing any headspace.   
Analyses were completed within three hours of sampling.  Prior to measurement, 
samples were brought to 20°C by partially submerging the serum bottles in a 
Neslab RTE7 temperature bath for 16 minutes.

Data precision was evaluated by analysis of duplicate samples (multiple samples 
from the same Niskin bottle on the rosette).  The pooled standard deviation of 
the ~450 duplicate analyses is 0.0007 pH units.

Accuracy of spectrophotometric pH measurements is difficult to constrain with no 
agreed upon calibration procedure.  For this cruise two approaches were made.  
First, since both total alkalinity and total carbon were measured on the same 
Niskin bottles as pH, an independent estimate of pH can be obtained from 
equilibrium equations.  However, there are uncertainties involved in these 
calculations, and the pH can only be calculated accurately to 0.01 pH units. 
Second, pH analyses of 25 Certified Reference Materials (currently only 
certified for DIC and alkalinity) were performed.   A review of the accuracy of 
the pH measurements is currently underway, and large changes (~0.01) in the 
final reported values are likely.  Despite these uncertainties, confidence in 
the precision of the measurements remains high.  Any changes will most likely be 
the addition of constant or an offset based on a function of pH.

No correction for HgCl2 addition has been made for the reported preliminary pH 
values. However, previous experiments suggest a very small correction for HgCl2 
(~0.0003 pH unit increase) might be appropriate for all measured values.

CARBON ISOTOPES (C-13/C-14)
Darcy Metzler, RSMAS
(PIs: Robert Key, Princeton; Ann McNichol, WHOI)


13C/14C water samples were drawn routinely from the Rosette casts.  Approximate-
ly every 5 degrees of latitude the entire water column was sampled (24 samples). 
In between most of the full profiles, the shallowest 16 bottles were sampled. 
Vertical profiles were collected at 34 of the 129 total stations.

Samples were collected in 500 ml glass stoppered bottles. First, the stopper was 
removed from the dry flask and placed aside. Using silicone tubing, the flasks 
were rinsed well with the water from the Niskin bottle. While keeping the tubing 
near the bottom of the flask, the flask was filled and allowed to overflow about 
half its volume. Once the sample was taken, a small amount (~30 cc) of water was 
removed to create a headspace and ~0.2ml of 50% saturated mercuric chloride 
solution was added. This was the same supply and volume of mercuric chloride 
solution used for the DIC samples. 

After all samples were collected from a station, the neck of each flask was 
carefully dried using Kimwipes. The stopper, previously lubricated with Apiezon 
grease, was inserted into the bottle. The stopper was examined to insure that 
the grease formed a smooth and continuous film between the flask and bottle. A 
rubber band was wrapped over the bottle to secure the stopper. The filled 
bottles were stored inside the ship's laboratory prior to being loaded into a 
container and shipped to Woods Hole, MA after the ship returned the to the U.S. 
The samples will be analyzed at the National Ocean Sciences AMS lab in Woods 
Hole, MA using published techniques developed for the WOCE program.

DOC and TDN samples were taken from every Niskin bottle at approximately every 
other station. 1594 samples were taken from 68 stations in total. Samples from 
depths shallower than 250 m were filtered through GF/F filters using in-line 
filtration. Samples from deeper depths were not filtered. High density 
polyethylene 60 ml sample bottles were 10% HCl cleaned and Mili-Q water rinsed. 
Filters were combusted at 450°C overnight. Filter holders were 10% HCl cleaned 
and Mili-Q water rinsed. Samples were introduced into the sample bottles by a 
pre-cleaned silicone tubing. Bottles were rinsed by sample for 3 times before 
filling. 40-50 ml of water were taken for each sample. Samples were kept frozen 
in the ship's freezer room. Frozen samples were shipped back by express shipping 
to RSMAS for analysis.

Ocean current velocity by Lower Acoustic Doppler Profiler (LADCP) 

A University of Hawaii (UH) system was used to collect horizontal ocean current 
velocity from a Lowered Acoustic Doppler Current Profiler (LADCP). Final 
processing was completed using the Lamont-Doherty Earth Observatory (LDEO) LADCP 
software [Thurnherr, 2008]. 


LADCP System Setup 

One 24-bottle CTD rosette was used during the whole cruise. On deck, the rosette 
laid on a platform that could be tracked in and out the hangar. This system was 
necessary for LADCP operations as the LADCP cables are purposely short (to limit 
noise) and could not have reached the rosette outside the hangar.

The rosette had two WH300-kHz LADCP, one up-looker and one down-looker, and an 
oil-filled 58V rechargeable lead-acid battery pack. The installation on deck 
consisted of a Lenovo S10e for data acquisition and processing, as well as a 
TDK-Lambda battery charger/power supply. The LADCP heads and battery pack were 
mounted inside the 24-bottle rosette frame and connected using a custom 
designed, potted star cable assembly. One head (master) was placed looking 
downward underneath the bottles at approximately the same height as the CTD 
instruments, the other head looking upwards (slave) above the bottle trigger 
mechanism. The battery pack and LADCP were mounted on opposite sides of the 
rosette frame center to avoid unequal balancing.

Power supply and data transfer was handled independently from any CTD connec-
tions. While on deck the instrument communication was set up by means of a 
network of RS-232 and USB cables, using a UH python software for instrument 
control and data transmission, and version IX_6beta of the LDEO software for 
data processing in Matlab [Thurnherr, 2008].

The set up of the two LADCP heads follows the master-slave set-up: one instru-
ment (master) dictates when the second instrument (slave) starts and stops to 
ping. For deployment, the slave was first prepared and started to ping only once 
the master did. For retrieving the data, the master was first stopped to ping 
which immediately stopped the slave. The command file of the master (downlooker) 
is:


CR1
WM15 
TC2 
TB 00:00:02.00 
TE 00:00:00.80 
TP 00:00.00

WF0800 
WV330 
EZ0011101 
EX00100 
CF11101 
SM2 
SA001 
ST0 

The command file for the slave (up-looker) is: 
CR1 
WM15 T
C2 
TB 00:00:02.00 
TE 00:00:00.80

EZ0011101 
EX00100 
CF11101 
SM1 
SA001 
SW05000 


In the command files, SM1 and SM2 tell if the instrument is a master or slave, 
respectively. The slave was set-up to ping 500 ms after the master in order to 
avoid interference: this is indicated by the command SW05000 in the master file. 

At the beginning of the cruise, it was necessary to assure that the LADCP and 
CTD acquisition computer clocks be both in sync with the ship clock to assure 
that the absolute time recorded by the CTD and LADCP be the same. 


LADCP Operation and Data Processing 

On arrival at each station the LADCP heads were switched on for data acquisition 
by using the LADCP software. Then communications and power cabling were 
disconnected and all connections were sealed with dummy plugs. After each cast 
the data cable and the power supply were rinsed, reconnected, the data 
acquisition terminated, the battery charged, and the data downloaded. It took 
about 20 minutes to download the data from each data and during this time, the 
new battery was fully charged. 

Immediately after each cast, preliminary processing was executed, combining CTD, 
GPS, and shipboard ADCP data with the data from the LADCP to produce both a 
shear and an inverse solution for the absolute velocities. The preliminary 
processing produced velocity profiles, rosette frame angular movements, and 
velocity ASCII and Matlab files. Plots and data files were put on the ship 
website for immediate visualization. 


Problems 

No major problem was encountered. On station 12, the communication failed 
between the computer and the down-looker instrument so the cast was done only 
with the up-looker with no master-slave set up. Communication was re-established 
afterwards.
 
For station 72, LADCP data were taken for CTD cast #1 (from surface down to 
bottom then up to 1600 m) and #2 (1600 m up to the surface). CTD cast #1 and #2 
were part of the same physical cast and CTD data acquired from the CTD group 
from both casts were merged to form one complete cast, renamed cast #1 for LADCP 
processing. No LADCP data were taken at Station 72 for CTD cast #3. 

A similar procedure was followed for station 79 except that LADCP data were 
acquired for CTD cast #3. The official cast is the first one. 

For station 82, there were two CTD casts, one full and one down to 1600 m only. 
LADCP data were acquired in both cases and the official cast will be the first 
one. 

Between 102 and 103, we removed the up-looker ADCP to replace the rubber pads 
that were sliding down with the ADCP. The ADCP was then put back. The rubber 
pads used and the method to fix them on the ADCP frames were not preventing the 
ADCP from sliding down about 0.5-1 mm a day. The down-looker ADCP was secured by 
a line at the beginning of the cruise and stopped sliding down immediately. This 
was not the case for the up-looker and explains why we had to add a layer of 
rubber and re-position the instrument between station 102 and 103. 


Data distribution 

LADCP data are distributed separately from the rest of the cruise data. They can

SADCP
(PI: Julia Hummon, U. Hawaii)


Shipboard Acoustic Doppler Current Profiler

The Ronald H Brown has a 75kHz acoustic Doppler current profiler ("ADCP", 
Teledyne R.D. Instruments) for measuring ocean velocity.  Specialized software 
developed at the University of Hawaii has been installed on this ship for the 
purpose of ADCP acquisition, processing, and figure generation during each 
cruise.

The acquisition system ("UHDAS", University of Hawaii Data Acquisition System) 
is an Open Sources suite, written in C and Python; processing software is in C, 
Python, and Matlab.  UHDAS acquires data from the OS75 instrument, gyro heading 
(for reliability), Mahrs heading (for increased accuracy), and GPS positions 
from various sensors. Single-ping data are converted from beam to earth 
coordinates using known transducer angles and gyro heading, and are corrected by 
the average mahrs-gyro difference over the duration of the 5-minute profile.

Groups of single-ping ocean velocity estimates must be averaged to decrease 
measurement noise.  These groups commonly comprise 5 minutes. Bad pings must be 
edited out prior to averaging.  This is done by UHDAS using a collection of 
criteria tailored to the instrument type and frequency, and to the specific 
installation.

UHDAS uses a CODAS (Common Oceanographic Data Access System) database for 
storage and retrieval of averaged data.  Various post-processing steps can be 
administered to the database after a cruise is over, but the at-sea data should 
be acceptable for preliminary work.

UHDAS provides access to regularly-updated figures and data over the ship's 
network via samba share and nfs export, as well as through the web interface. 
The web site has regularly-updated figures showing the last 5-minute ocean 
velocity profile with signal return strength, and hourly contour and vector 
plots of the last 3 days of ocean velocity.


Shipboard Doppler sonar work on this cruise

During the cruise, the Ocean Surveyor was run in "interleaved" pinging mode, 
where it can sample in broadband mode (higher resolution, reduced range) and in 
narrowband mode (coarser resolution, increased depth range) with alternating 
pings.  These are processed into two
separate datasets.



Data quality

Typical ADCP data quality issues are 
  • clock errors
  • heading correction
  • data loss or compromise:
     - data loss due to bad weather, bubbles, etc
     - data compromise due to deep scattering layers
     - depth penetration

Clock: 

The ADCP computer was synced to the network time server during the cruise. This 
worked fine; times are in UTC; decimal days for processed ADCP data are zero-
based, i.e. 2010/01/01 12:00:00 is 0.500000 

Heading:

Gyro headings were corrected using the Mahrs.  Heading correction is critical to 
minimize cross-track errors induced by errors in heading. A one degree heading 
error results in a 10cm/s cross-track error in shipboard ADCP data if the ship 
is traveling at 12kts. The Mahrs was reliable, and within the constraints of the 
calibration  mechanisms available, appeared to do a good job of correcting the 
heading. The compass correction varied from near 0-1deg at low latitudes and 
increased to 3 degrees at the southern reaches of the cruise.


Data loss or compromise:

The broadband dataset (8m vertical bins) was negatively impacted by weather, 
especially south of 30°S.  Much of the underway data was missing and range 
rarely exceeded 200m. Between 30°S and 20°S, there were fewer gaps, but the 
range was still only 200m.  Approaching the equator, the range increased to 300-
400m.

The narrowband dataset had fewer gaps and better range.  South of 30°S, there 
were few gaps and the range was 400m-500m. Between 30°S and 20°S, range was 500-
600m.  North of 20°S, the range was 600m throughout.


Overview

All in all, the instrument, ancillary devices, and acquisition system performed 
well.




DRIFTER DEPLOYMENTS

(PI: Shaun Dolk, AOML)


A total of eighteen SVP drifters, provided by the Global Drifter Program, were 
deployed during the cruise. The deployment procedure involved removing the start 
up magnet and then the plastic packaging  before deployment. The drifters were 
deployed after the completion of the CTD station closest to the target 
deployment location. Once the ship was re-positioned and began steaming at 
approximately one knot,  the drifter was thrown off the fantail of the ship. The 
time and position of each drifter deployment was recorded and transmitted via e- 
mail to the Drifter Center at AOML(Shaun.Dolk@noaa.gov).


The following eighteen drifters were deployed:

ARGO FLOAT DEPLOYMENTS
(PI: Gregory C. Johnson, PMEL)


Eight ARGO profiling CTD floats were launched during this cruise at the request 
of WHOI and AOML ARGO groups. These floats are part of the Argo array, a global 
network of over 3000 profiling floats. The floats are designed to sink to a 
depth of about 1000m. They then drift freely at depth for about ten days, before 
sinking to 2000m and then  immediately rising to the surface, collecting CTD 
data as they rise.  Conductivity (salinity), temperature, and pressure are 
measured and recorded at about 73 levels during each float ascent. At the 
surface, before the next dive begins, the acquired data is transmitted to shore 
via satellite, along with a location estimate taken while the float sits at the 
surface. The typical life time of the floats in the water is about four years. 
All Argo float data is made publicly available on the web in real-time at 
http://www.usgodae.org/argo/argo.html.

All floats were checked on the ship and started at least a day before  
deployment, by passing a magnet over the 'reset' area on the float. Each float's 
startup time was logged. When in position, each float was then launched by 
carefully lowering it into the water using a hand-
held line strung through the supplied deployment straps. Each float was deployed 
in the protective box the float shipped with. Deployments were done after the 
completion of the CTD station nearest to the requested deployment location, 
immediately after the ship had turned, and begun its course to the next station 
and had reached a speed of approximately one knot. All eight floats were 
deployed successfully.  An e-mail report was sent to WHOI or AOML, depending on 
who provided the float, to report the float ID number, float start time, exact 
float deployment time, location, wind speed, wind direction, sea state and 
deployer's name(s).


Argo float deployment information is summarized in the table below.

MAERI
Darcy Metzler, RSMAS
(PI: Peter Minnett, RSMAS)


For many years scanning radiometers on satellites have been providing global 
fields of sea-surface temperature (SST) and these have found many applications 
in oceanography, air-sea exchange studies, meteorology, including numerical 
weather forecasting, and climate change research.

The utility of the satellite-derived SSTs is determined by their uncertainties 
and these are largely determined by the residual errors in the correction for 
the effects of the intervening atmosphere. The most reliable way to determine 
these uncertainties is to compare the satellite-derived values with those from 
an independent data source taken at the same time in the same place. Given the 
effects of variable near-surface temperature gradients, the best sources of 
validating data are ship-board radiometers, but for these to provide useful data 
they have to be very accurate (uncertainties <0.1K) with calibration traceable 
to National Institute of Standards and Technology reference standards. The 
Marine-Atmospheric Radiance Interferometer (M-AERI) is one of a few such 
radiometers, and the track of the NOAA S Ronald H Brown provides the opportunity 
to take validation measurements in a very under-sampled part of the ocean.

The M-AERI is a Fourier-Transform Infrared (FTIR) Spectroradiometer that 
operates in the range of infrared wavelengths from ~3 to ~18µm and measures 
spectra with a resolution of ~0.5 cm^-1 . It uses two infrared detectors to 
achieve this wide spectral range, and these are cooled to ~78o K (close to the 
boiling point of liquid nitrogen) by a Stirling cycle cryo-cooler to reduce the 
noise equivalent temperature difference to levels well below 0.1K. The M-AERI 
includes two internal black-body cavities for accurate real-time calibration. A 
scan mirror, which is programmed to step through a pre-selected range of angles, 
directs the field of view from the interferometer to either of the black-body 
calibration targets or to the environment from nadir to zenith. The sea-surface 
measurement also includes a small component of reflected sky radiance, so the 
derivation of the skin SST from the M-AERI spectra requires compensation of the 
reflected sky radiances that are part of the sea-viewing measurement, and of the 
emission from the atmosphere between the instrument and the sea surface. The 
interferometer integrates measurements over a few tens of seconds, to obtain a 
satisfactory signal to noise ratio, and a typical cycle of measurements 
including two view angles to the atmosphere, one to the ocean, and calibration 
measurements, takes about ten minutes. The instrument is run continuously so 
that measurements are taken within minutes of the satellite overpasses.

• Samples analyzed, QC'd Bob Key 
Date: 2012-04-27
Data Type: C14/HeTr/Trans
Action: Status Update
Note: 
The A13.5 C14 samples have been analyzed. Not long ago I ran the data 
through 1st QC and returned the results to WHOI. They are doing the final 
checking/analysis of samples that were anomalous in QC. We should have 
these results to you in short order. The submitted data will be "final".

There are other cruise data that are in similar shape/status. 

I will simultaneously submit results to CCHOD and CDIAC via normal 
procedures. 

Talked to Ann McNichol regarding A13.5. There are a couple of additional 
samples from the QC that they want to re-run (the 500ml samples have 
enough carbon for 2 runs when required). Those samples are in line, but 
it will be 1-2 months before they are finished.

• pH data NOT final Andrew Dickson

Action: User Caution
Note: 
The pH data has flaws that have not been fully characterized. Ideally, I 
feel we should remove any pH data at this time.

Data Type: pH/ALKALI
Action: User Caution
Note: 
I am certain however that adjustments will be made to the alkalinity and 
pH data before they are "final", the importance of those adjustments 
for users rather depends on the use that is being made of the data.

        - In order to merge I replaced the units for PH_TOT.  I changed 
          them from preliminary to a blank string.
          These data were NOT merged.
        - I merged ALKALI and ALKALI_FLAG_W with no issues.
        - Everything looks good in JOA and the bottle comparer.
        - I converted the file to Woce and NetCDF.  The NetCDF file opens 
          without problems in JOA.

Action: Website Update
Note: 
2011.03.01
   FCO2,FCO2_TMP, and FCO2_FLAG_W
      - I merged these columns on cchdo.  I double checked using the 
        bottle comparer and JOA, and things looked fine.

2011.03.02
   SALNTY,SALNTY_FLAG_W,SILCAT,SILCAT_FLAG_W,NITRAT,NITRAT_FLAG_W,NITRIT,
   NITRIT_FLAG_W,PHSPHT,PHSPHT_FLAG_W
     - These data were recieved in a space delimited format.  I converted 
       this to csv.  The SAMPNO and the CASTNO were joined together to 
       form one number; I seperated the values.  At this point the data 
       merged, and looked ok in JOA. The submitted nutrients data had 9 
       decimal places, this was rounded to 2 decimal places in our files.

     - CFC, SF6 came from Bullister on 2010.12.08 and 2010.12.09, with 
       the 2010.12.09 replacing the previous submission.  
     - Wisegarver submitted NUTS on 2010.12.  
     - Kozyr resubmitted the Bullister data, along with NUTS on 
       2010.12.20. 
     - Susan submitted FCO2,FCO2_TMP, and FCO2_FLAG_W, but I didn't find 
       the data, just a calculation methods document.
     - Susan emailed me the FCO2 data on 2011.01.31.  I submitted it for 
       her.

2011.02.07
  OXY data from Chris Langdon:
     - I changed the units for REFTMP from ITS-90 to DEG C.  This was 
       only for the purpose of merging.  The REFTMP from Chris Langdon's 
       file was not merged. 
     - I merged the OXYGEN and OXYGEN_FLAG_W columns with no problems.

  - The data merged without issue, and I double checked it with the 
    bottle compare tool.
  - Before merging TDN and DOC data from Alex Kozyr's 2010.10.20 
    submission I changed the units for Depth from CORR.M to METERS, and I 
    change the pressure units from DBARS to DBAR.
  - Overall, I merged TCARBN, TCARBN_FLAG_W, TDN, TDN_FLAG_W, DOC, and 
    DOC_FLAG_W.  Data merged cleanly and no problems were found.
  - I double checked the new file in JOA, everything looked fine.  I 
    converted the exchange data to woce and netcdf, and I placed these 
    files online.

Reformatting notes for a13.5 sum, woce and exchange bottle files.

SUM:  
As per Mary Johnson, edited UNC DEPTH to COR DEPTH.
Ran sumchk with no errors.  Added header and WHP-ID. 
Renamed a13.5_33RO20100308su.txt.

WOCE HYD:
Added name/date stamp.
Edited: DEG_C to DEG C
        UATM@T to UATM
Ran wctcvt, which did not recognize the following parameters:
  CCL4, PCO2, PCO2TMP, PH_TOT, PH_TMP, SF6, DOC, TDN, REFTMP
It also indicated that there was a mismatch between asterisked
columns and total quality bytes, however this is not the case.
This could be because it does not recognize all the parameters.

In order to confirm, I converted the woce file into exchange and
format checked the resultant exchange file with copy_bottle_data.rb.
The file converted without error.  Therefore the formatted WOCE file
was used.  Renamed a13.5_33RO20100308hy.txt


Exchange HYD:
Edited: DEG_C to DEG C
        UATM@T to UATM
        REFTEMP to REFTMP
        M to METERS
        DBARS to DBAR
Added DBAR to CTDRAW units

Ran file through copy_bottle_data.rb to re-order parameters according
to the CCHDO preferred order list.      
Added previous/original stamp back into file.  Renamed 
a13.5_33RO20100308_hy1.csv


NETCDF:
Created netcdf files from exchange file with no errors.  These files
opened in JOA, however viewing data within JOA was problematic.  This
is believed to be a bug in JOA and not an error in netcdf format.  A
ncdump of the file to the screen, shows correct formatting.  Therefore,
the files were zipped together and placed online.  File is  
a13.5_33RO20100308_nc_hyd.zip


Ran update script and sent notes file to Jerry.

  header correction Mary C. Johnson 
Date: 2010-06-04
Data Type: BTL
Action: Submitted
Note: 
I incorrectly labeled the column "UNC DEPTH" in the a13_5.sum file I 
submitted yesterday; it's corrected meters.  Same with the exchange file 
- but that doesn't label the depth one way or the other.  I put a 
replacement for the .sum and _hy1.csv files on our website, with just 
that one header changed:

Also, I meant to let you know that the date/time columns in the exchange 
file is the date/time that particular bottle tripped; not the 
bottom-of-cast time.  I notice a time of 2400 (with the correct date of 
the previous day) on station 31-1-18 - it's a rounding error of a 
23:59:30 timestamp on that trip.  We have started using lat/lon of the 
cast "bottom" for the lat/lon on each bottle... but the actual time the 
bottle tripped could be useful information we didn't want to lose.
