Measurement Program Summary


NOAAS Ronald H. Brown departed Papeete, Tahiti mid-morning on 10 April 2015
and arrived at Pearl Harbor in Honolulu, Hawaii at 1500 HAST on 12 May
2015. A total of 113 stations were occupied during P16N Leg 1: 1 test
station (999) to 1000 dbars; and 112 positions along the P16N line, each
with one CTD/O2/LADCP/rosette cast to within 8-12 meters of the bottom.  A
total of 9 Argo floats were deployed during the cruise.  CTD PTSO2,
Altimeter, Transmissometer, CDOM Fluorometer, UVP, LADCP and Chipod
electronic data, plus up to 24 water samples, were collected during each
cast.





                                    -5-

A 24-position, 11-liter Bullister bottle rosette frame (NOAA/AOML) was used
to collect data.  The distribution of the bottle samples during the cruise
can be seen in Figures 1 and 2 below.

          Figure 1 P16N Leg 1 Sample distribution, stations 1-70.

         Figure 2 P16N Leg 1 Sample distribution, stations 70-112.

Ship's Underway Data Acquisition

Navigation data were acquired at 1-second intervals from the ship's Furuno
GP150 P-Code GPS receiver by the SIO/ODF Linux system from the start of the
cruise. In addition, centerbeam depth data, with a correction for hull
depth included in each data line, were acquired directly from the ship's
Seabeam/Kongsberg EM122 system.  These data were used to connect the
timestamps for each cruise deployment with position and ocean depth
information.

The centerbeam depths were also continuously displayed, and data were
manually recorded at cast start/bottom/end on CTD Cast Logs.

Etopo2 bathymetry data were merged with navigation time-series data after
each cast and used for bottle-depth sections shown elsewhere in this
report.

Various underway data were sent from the ship's computer systems to a
serial feed on the Linux system.  These data were stored at 1-second
intervals:


     Column   Data Type and units
          1   Winch payout (uncorrected meters)
          2   Winch speed (meters/minute)
          3   Winch tension (pounds)
          4   Multibeam Bottom Depth (meters to tenths) - corrected for Sound Velocity
                   but not for hull depth (approx. 5.8m more)
          5   UTC Julian Date (day of year in 2015)
          6   UTC Time (hh:mm:ss)    (hh=hours, mm=minutes, ss=seconds)
          7   GPS Latitude  (ddmm.mmmmH)   (d=degrees, m=minutes to 4 places, H=Hemisphere)
          8   GPS Longitude (dddmm.mmmmH)
          9   TSG Sea Surface Temp (SST - degrees Celsius)
         10   TSG Sea Surface Salinity (last calibrated 7-Jan-2015)
         11   True Wind Speed (knots) - divide by 1.9438445 to get m/sec
         12   True Wind Direction (compass degrees)
         13   Barometer - Sea Level (millibars)
         14   Relative Humidity (%)
         15   Air Temperature (degrees Celsius)



Serial Feed Problems

There were numerous dropped bits in the serial feeds coming into the Linux
system at the start of the cruise.  Several large gaps in navigation data
occurred for two nights in a row due to spikes in date or time.  As a
result, the RS232 Rocketport serial card was reseated and checked, then
switched out for an older model Octaport that functioned much more
reliably.

Missing navigation and bathymetry data gaps were filled in from ship's
files. The first 5 days of messy Underway data were fixed manually over the
course of the next week. The first 8 columns of Underway data have been
more scrupulously checked; columns 9 through 15 may still have some errors
until Julian Date 105 at 10:02 UTC.

Underwater Electronics Package

A Sea-Bird Electronics SBE9plus CTD was connected to a 24-place SBE32
carousel, providing for two-conductor sea cable operation.  Two conducting
wires in the 0.322 sea cable were soldered to their counterparts in the end
termination: black for signal, and white for ground; the third (red) wire
was cut back/unused.  Power to the CTD and sensors, carousel and most
instruments attached to the CTD was provided through the sea cable from an
SBE11plus deck unit in the computer lab.




                                    -6-

The CTD supplied a standard SBE-format data stream at a data rate of 24 Hz.
The CTD provided pressure plus dual temperature, conductivity and dissolved
oxygen channels.  The CTD system also incorporated an altimeter,
transmissometer, fluorometer, and Underwater Vision Profiler (UVP).  A
Lowered Acoustic Doppler Profiler (LADCP) and Chipods were also mounted on
the rosette frame; both were powered separately and collected data
internally.

The CTD system was outfitted with dual pumps. Primary temperature,
conductivity and dissolved oxygen were plumbed into one pump circuit; and
secondary temperature, conductivity and oxygen were plumbed into into the
other.  The CTD and sensors were deployed vertically.  The primary
temperature and conductivity sensors were used for reported CTD
temperatures and salinities on all casts.  The secondary temperature and
conductivity sensors were used as calibration checks.

The fluorometer and transmissometer were removed from the package after
cast 41/2.  The UVP was powered independently of the CTD and recorded data
internally during all casts, but also transmitted data through the CTD
until it was detached after station 43.  The transmissometer was added back
before station 50.

Water Sampling Package

The NOAAS Ronald H. Brown has two Markey DESH-5 winches. The AFT winch was
used for most casts on P16N. The FWD winch was used for stations 41/2-49/1
in an attempt to identify the source of numerous modulo errors (non-
sequential modulo/scan counts in the CTD data) and unsupported modem
messages (from the carousel) during the casts.  Reterminations of the winch
wires are listed in Table 1 at the end of this section.

The AFT wire was lubricated with Strancore when it came from the
manufacturer, and again during the up-cast of station 93. The lubrication
was suspended for the last (surface) 100m of wire to avoid sample
contamination.

All rosette casts were lowered to within 8-12 meters of the bottom, using
the multibeam center depth value plus the altimeter on the rosette to
determine distance.  Three sampling schema were used in rotation to stagger
standard sampling depths for consecutive stations.  There were occasional
exceptions made to the order of the schema or to capture a feature in the
water column.

Four different SBE32 carousels were used during P16N in order to
troubleshoot numerous "unsupported modem message" errors returning from the
carousels.  These came at random times, down-cast or up-cast, and almost




                                    -8-

always when the package came out of the water at the end of a cast. The
errors coincided with carousel "resets" on several up-casts, causing
multiple open bottles from "re-tripping" already-tripped positions.  Only
one carousel (PMEL 163) was replaced due to failing latches on bottles 9
and 22, which did not fire for 3 casts in a row.

The 24-place SBE32 carousels had occasional problems with releasing
lanyards or mis-tripped bottles.  Repairs or replacements and bottle
height/lanyard adjustments were made as the cruise continued.

Rosette maintenance was performed on a regular basis. O-rings were changed
and lanyards repaired as necessary. Bottle maintenance was performed each
day to ensure proper closure and sealing.  Valves were inspected for leaks
and repaired or replaced as needed.  Periodic leaks were noted on sample
logs; several bottles were replaced early in the cruise due to persistent
leaks. These are documented in the quality comments section of the
Appendix.

Bottle Sampling

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


     o   Chlorofluorocarbons(CFCs) /N2O /SF6
     o   3Helium / Neon
     o   Dissolved O2
     o   Dissolved Inorganic Carbon (DIC)
     o   Total pH
     o   Total Alkalinity (TAlk)
     o   13C /14C-DIC
     o   Dissolved Organic Carbon / Total Dissolved Nitrogen (DOC/TDN)
     o   DO14C
     o   POC
     o   Chlorophyll a
     o   Tritium
     o   Nutrients
     o   Salinity
     o   137Cs /134Cs /90Sr /129I
     o   Black Carbon



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 that sampling progressed in the proper drawing
order.

Normal sampling practice included opening the drain valve and then the air
vent on the bottle, indicating an air leak if water escaped.  This
observation together with other diagnostic comments (e.g., "lanyard caught
in endcap", "valve left open") that might later prove useful in determining
sample integrity were routinely noted on the sample log.  Drawing oxygen
samples also involved taking the 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 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-8.1.23-10) run on a
CentOS-5.11 Linux system. A web service (OpenACS-5.3.2-3 and
AOLServer-4.5.1-1) 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.




                                    -9-

Shipboard CTDO data were re-processed automatically at the end of each
deployment using SIO/ODF CTD processing software v.5.1.6-1. The CTDO data
and bottle trip files acquired by SBE SeaSave on the Windows 7 workstation
were copied onto the Linux database and web server system.  Pre-cruise
calibration data were applied to CTD Pressure, Temperature and Conductivity
sensor data, then the data were processed to a 0.5-second time series.  A
1-decibar down-cast pressure series was created from the time series.

CTD up-cast data at bottle trips were extracted and added to the bottle
database to use for CTD Pressure, Temperature and Salinity data in the
preliminary bottle files.  Pre-cruise calibration data were applied to
these three parameters, in addition to PMEL preliminary shipboard
conductivity corrections.

Time-series CTDO data from both down- and up-casts were matched along
isopycnals to upcast trip data, then fit to bottle O2 data using the
SIO/ODF CTD processing software.  The coefficients from these fits were
applied, then CTD Oxygen data were extracted from the time-series up-cast
data files and added to the database for quality control of bottle
Dissolved O2 data.

The NOAA/PMEL final PTSO data will replace the preliminary SIO/ODF CTD data
in the bottle files after submission to CCHDO.

Cast Log and Sample Log information plus any diagnostic comments were
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) [Joyc94].

Various consistency checks and detailed examination of the data continued
throughout the cruise.  Log notes were cross referenced with sample data
values and quality coded. A summary of Cast Log and Sample Log comments,
mis-trips, bottle lanyard issues and associated quality codes can be found
in the Appendix.
