2.01 CTD
At a minimum, 1,000 meter CTD casts shall be
conducted at each mooring site between 08(09)°N and 08(05)°S for sensor inter‑comparison purposes. As time permits, additional or deeper CTD’s
should be conducted whenever addition of the CTD’s will not impact scheduled
mooring work. For example, if the ship
would arrive at the next mooring site in the middle of the night, it is
preferable to do CTD’s on the way, rather than remain hove to waiting for
daylight. Another example would be when
mooring operations are significantly ahead of schedule. Beyond those at mooring sites, CTD’s should
be conducted in the following order of priority:
·
1,000m CTD’s at one degree latitude
intervals between 12°N and 08°S, along the ship’s trackline.
·
Extend 1,000m CTD’s at mooring sites to a
minimum of 3,000m or a maximum depth of 200m from bottom. Four to six deep casts are optimal, occurring
at the beginning and end of the cruise as well as at both equatorial sites.
·
1,000m CTD’s every one‑half degree of latitude between 03°N and
03°S.
·
Additional calibration CTD’s to be
determined by Chief Scientist.
The CTD Rosette should have 24 Niskin bottles
available for use by ancillary projects.
2.02 Atlantic Oceanographic and Meteorological
Laboratory (AOML) Surface Drifters
The Global Drifter Center at NOAA/AOML requests
drifter deployments on an ancillary basis.
The drifters are small, easily deployed devices that are tracked by
ARGOS and provide Sea Surface Temperature (SST) and mixed layer currents. The global array of drifters provides SST ground
truth for NOAA’s polar orbiting satellite AVHRR SST maps. They also provide data to operational
meteorological and ocean models, and research ocean current data sets.
AOML drifters are scheduled at the following
positions:

2.03 Pacific Marine Environmental Laboratory
(PMEL) Argo Profiling CTD Floats
Ten
Argo floats are scheduled for deployment on this cruise. Individual deployment positions can be
shifted by a degree or so along the ship track if more convenient. Each float weighs about 56 lbs. The boxes weigh about 200 lbs. full and are
82” long x 17” high x 23” long. Boxes
cannot be stored or transported on their small ends. The floats are sensitive to high
temperatures, so as space for a pair of floats becomes available on the
computer lab rack, it will be desirable to move floats from the next box to the
rack at the earliest convenient time. A
manual for float testing and deployment has been sent to the ship. Float deployment locations are as follows:
Float
number deployment positions will be determined prior to sailing by the Argo
Program.
Argo float questions should be directed to:

2.04 Discreet Gas Sampler
Whole air samples are cryogenically
dried and pumped into glass flasks by an automated system in the computer
lab. Following the cruise, the flasks
are returned to Princeton University for analysis by prepaid FEDEX. Pairs of flasks are collected while the ship
is underway at 08°N, 04°N, 00°, 04°S, and 08°S along the 125°W and 140°W lines. Automated sampling cycle is approximately five
hours. It is anticipated that the Survey
Technician will perform the maintenance tasks.
The Survey Technician will be shipping the samples back to Princeton
University.

2.05 Dissolved Inorganic Carbon (DIC) Analysis
A 0.5 liter sea water sample from surface CTD
casts will be taken and stored for later dissolved inorganic carbon
analysis. Sample jars and Scripps
Institute of Oceanography will provide sample jars and mercury chloride
solution. It is anticipated that the
Survey Technician, together with embarked scientific personnel will take the
samples. A small bench-top drill press
is installed on the ship to assist with the bottle capping process. Samples will be collected when the ship docks
in San Diego, California.

2.06 TAO-CO2 Moorings
The carbon group at PMEL has mounted sensors on moored buoys
within the TAO Array to provide high-resolution time-series measurements of
atmospheric boundary layer and surface ocean CO2 partial pressure (pCO2). These data are used to evaluate the temporal
variability in air-sea CO2 fluxes and to assist in examining the mechanisms controlling CO2 fluxes. The pCO2 systems will be replaced at 00° 140°W.

sample from surface CTD casts will be taken and stored for later Nitrate N and
Oxygen isotope analysis. Sample jars
will be provided by Scripps Institute of Oceanography. It is anticipated that the Survey Technician,
together with other embarked scientific personnel will take the samples.

2.08 Equatorial Box Project
Equatorial Box Project (Behrenfeld)
The
overall objective of this effort is to utilize the mooring observations along
the 125 and 140 TAO lines along with additional cruise measurements to define a
3-dimesional ‘box’ in which and through which inherent and advective properties
can be defined and used as input constraints for testing and developing
carbon-focused satellite ‘conversion’ models and coupled ecosystem-circulation
models. An emphasis during this 3 year
project will be on characterizing mixed layer and euphotic zone properties, and
thus much of the measurement suite is focused on samples collected by the
ship’s flow-through system, thus minimizing impacts on ship operations and
scheduling. Additional discrete samples
will also be collected from the CTD during scheduled casts. Core measured variables will be: (1) variable
fluorescence (using a benchtop Fast Repetition Rate fluorometer (FRRf)), (2)
beam attenuation (using two beam transmissometers (553 and 660 nm)), (3)
particulate backscattering (using a ECO vsf and ECObb), (4) particle abundance
and size spectrum (using a LISST), (5) particulate Carbon-Hydrogen-Nitrogen
analysis (CHN), (6) pigment concentration (HPLC & Turner), (7)
macronutrient concentration, (8) dissolved organic carbon (DOC), (9) dissolved
organic nitrogen (DON), (10) colored dissolved organic carbon (using an AC-9),
(11) sample location (GPS), (12) downwelling surface solar irradiance (PAR)
(using a Licor), (14) submarine irradiance (using a ctd mounted light sensor),
(15) photosynthesis-irradiance measurements (using 14C), (16)
profile inherent optical properties (with a deployable optics package), and
(17) sea surface ocean color (using a hyperspectral TSRB).
(1) FAST REPETITION RATE
FLUOROMETER/PRODUCTIVITY
The
FRRf measures variable fluorescence parameters in phytoplankton and provides
information on photosynthetic performance.
The FRRf measurements will be conducted on flow through samples from the
ship’s seawater system. These
measurements require approximately 1 L of seawater per hour. The instrument is automated and requires no
assistance from ship’s personnel. These
measurements will begin as soon as possible during the cruise and will continue
to the end.
(2) IN-LINE BEAM TRANSMISSOMETERS
Two
beam transmissometers will be used to study variability in particle scattering
properties and for comparison with CHN data.
These transmissometers will be run in continuous flow through mode in
the laboratory using the ship’s seawater system
(approximately 100 ml per minute).
No assistance from ship personnel is required.
(3) BACKSCATTERING
Backscattering
measurements will be conducted using the ship’s flow through seawater system
(approximately 100 ml per minute).
Backscattering provides another optical index of particle concentration,
but is sensitive to a different size fraction of the particle distribution than
the transmissometers. The backscattering
measurements will be conducted in a bucket in a sink in the ship’s laboratory
area. No assistance from ship personnel
is required.
(4) PARTICLE ABUNDANCE AND SIZE SPECTRUM
Particle
size and abundance will be measured using a Sequoia Instruments LISST
sensor. The LISST is very much like the
beam transmissometers, but detected light from the source beam is separated
into discrete forward scattering angles, which is subsequently inverted to
provide information on particle size distribution. The LISST will be run in continuous flow
through mode in the laboratory using the ship’s seawater system (approximately
100 ml per minute). No assistance from
ship personnel is required.
(5) PARTICULATE CARBON-HYDROGEN-NITROGEN
ANALYSIS
CHN
measurements involve filtration of seawater (2.8 L) through a Whatmann GFF
filter, preservation of the filter by freezing, and later analysis at Oregon
State University. Seawater will be
collected from the ship’s flow through system at every degree of latitudes
(total volume approximately 3 L).
Filters will then be packaged and stored in liquid nitrogen for
post-cruise analysis. No assistance from
ship personnel is required.
(6) PIGMENTS
Phytoplankton
pigment concentrations will be determined using a Turner fluorometer and by
HPLC. Equipment for Turner-based pigment
measurements is being provided by MBARI.
Turner fluorometer measurements will be conducted on CTD water samples
at 0, 10, 25, 40, 60, 100, 150 and 200m. The total volume used from each
bottle, including rinses is approximately one liter; except for the surface
bottle, which will require approximately three liters. Samples will be vacuum
filtered and the filters placed in glass scintillation vials with 10 ml of 90%
acetone and frozen. Turner measurements
will be made 24 to 48 hours after collection.
HPLC measurements will involve collection of 3 to 6 L of seawater from
the ship’s flow through system approximately 6 times a day, filtering samples
onto GFF filters, preservation in liquid nitrogen, and subsequent analysis
after the cruise at MBARI. No assistance
from ship personnel is required.
(7) MACRONUTRIENT CONCENTRATION
20
ml nutrient samples will be collected from the CTD at 0, 10, 25, 40, 60, 100,
150 and 200m. The total volume used from depth, including rinses, is
approximately 100 ml. Samples will then
be frozen in plastic scintillation vials for later analysis at MBARI. No assistance from ship personnel is
required.
(8-10) DISSOLVED ORGANIC CARBON (DOC), DISSOLVED
ORGANIC NITROGEN (DON), & COLORED DISSOLVED ORGANIC CARBON (cDOC)
Water
samples (40 ml and 100 ml, for the DOC/DON and cDOC, respectively) will be
collected from the CTD at 0, 10, 25, 40, 60, 100, 150 and 200m. The total
volume used from depth, including rinses, is approximately 200 ml. Samples will then be frozen in amber glass
bottles for later analysis at Bigelow Laboratory. No assistance from ship personnel is
required.
Colored dissolved
organic carbon (cDOC) is measured using an in-line ac9 with a 0.2 mm filter
placed on the inflow. The ac9 is very much like the beam transmissometers, but
it has two flow-through tubes and nine spectral channels. The detected light
from one source beam is a beam transmissometer (narrow angle detection) while
the other source beam is an absorption meter (wide angle detection). The ac9
will be run in continuous flow through mode in the laboratory using the ship’s
seawater system (approximately 100 ml per minute). No assistance from ship personnel is
required.
(12-13) SAMPLE LOCATION and SOLAR IRRADIANCE
A
hand-held GPS will be used to log ship location at 15 s intervals. Simultaneously, a Licor Data Logger (LDL)
will be used to log daily changes in solar irradiance. After consultation with the Field Operations
Officer the solar sensor will be mounted in an acceptable exterior location
free of shading. The LDL recorder will
be enclosed from the weather, while the sensor itself is water resistant and
will be exposed to the elements. The
sensor is very small (1" x 7/8") and the LDL recorder is 9" x
5".
(14) SUBMARINE IRRADIANCE.
A
Biospheric light sensor (cosine collector) will be mounted on the CTD frame and
data logged on the CTD recorder to determine light attenuation coefficients
through the water column. Oregon State
University will provide the necessary cable to connect the light sensor to the
CTD. The sensor is water tight to 5000
m. No assistance from ship personnel is
required.
(15) PHOTOSYNTHESIS-IRRADIANCE (PvE)
MEASUREMENTS
Samples for PvE
incubations will be collected from the flow through system at every latitude
and at 9:00, 12:00, and 15:00 along the 125 and 140 lines at 8o, 5o,
2o North and South and at the equator. Samples from 3 depths at these stations
would also be desirable (one time during the day corresponding to a scheduled
bottle cast). For each time and
location, 25 10-ml samples will be collected and place in a 25 ml glass
scintillation vial in a PvE incubator (an aluminum box ~18 inches on a side
that has 100 slots for vials, a light source and flow through tubing connected
to a floor-mounted temperature controller –LXWXH = 24”X12”X18”) Each sample is
spiked with 14C, and incubated in the wet lab in a hood provided by
C. Roesler at Bigelow for 1 – 2 hrs.
Samples will then be killed with concentrated HCl and allowed to degas
in the ventilated hood for 24 hrs.
Scintillation fluor will then be added to each sample and the total
activity determined by liquid scintillation counting (both on board and
post-cruise at Bigelow). Stock 14C
will be kept refrigerated in a sealed vial stored in a lock-box. All solid and liquid 14C waste, as
well as samples, will be stored in well marked containers and removed by
Bigelow scientists immediately following the cruise. Regular swipe tests will be conducted during
the cruise to ensure against 14C contamination. Space for waste
disposal containers during the cruise is required. No assistance from ship’s
personnel is required.
(16)
DEPLOYABLE OPTICS PACKAGE
A small, framed
deployable optics package will be used to characterize particle abundance and
composition and phytoplankton fluorescence.
The package can be hand lowered or lowered with an accessory winch.
Deployment and recovery requires about 15 minutes. If a winch is used, assistance from ship’s
personnel would be required. Deployments
would be made any of the planned stations (corresponding to TAO moorings) along
the 125 and 140 lines when the ship’s schedule permits. These deployments can be made at any time,
day or night. The optical package will
include a WetLabs AC9plus, backscattering sensor, digital chlorophyll
fluorometer, and a battery pack (these measurements are optional and at the
discretion of the TAO program, but are highly desirable).
(17) HYPERSPECTRAL TSRB
When permitted by the
ships schedule, deployments of a hyperspectral TSRB (radiometer buoy) would be
desired on any of the planned stations.
The measurement requires about 5-10 minutes for deployment and recovery
and would be done when time allows during daylight hours (9-3 local time). The sensor is all hand deployable, floats
away from the ship, and can be accomplished by a single person. No assistance from ship’s personnel would be
required.
(18) LAB BENCH SPACE
Lab
bench space is needed for the the flow through instrumentation (FRRf, beam
transmissometers, backscattering sensors and bucket, and LISST), the PvE
incubator (and adjacent floor space for the water chiller), and for filtrations
(pigment, CHN, DON, DOC). The benchspace
required for all these measurements is easily accommodated in the wet lab of
the Ka’imimoana.
(19) CHEMICALS

our suite of measurements, the following chemicals will be required and
provided by OSU and Bigelow (MSDS sheets will be provided):
2

2.08 Ancillary Measurements

ANCILLARY
MEASUREMENTS ON THE KA’IMIMOANA CTD PACKAGE

The CTD data currently collected by
the Ka’imimoana provide and excellent
picture of equatorial Pacific physical oceanographic properties. The addition
of two optical instruments will provide data on three important biological
parameters related to upper ocean productivity and carbon cycling.
The instruments, both manufactured
by WET Labs, Philomath, OR are (1) a C-Star transmissometer, and (2) an FLNTU
combined fluorescence/turbidity sensor.
The C-Star is approximately
rectangular in shape, dimensions 3.7 in × 2.5 in × 18.5 in (19.5 in including
bulkhead connector), 8 lbs in air, 6 lbs in water, rated to 6000m. The FLNTU is
a cylinder, 2.48 in diameter × 5.0 in length (plus bulkhead connector), 0.9 lbs
in air, 0.05 lbs in water, rated to 6000m.
The C-Star measures beam
attenuation, aka beam-c or Cp, by shining a light source (660nm) through an
open path (25cm) to a detector. The amount of light reaching the detector is
related to the particle concentration in the water, specifically the
concentration of particulate organic carbon (POC). The FLNTU measures two
parameters:
(1) chlorophyll fluorescence by shining a light source (470 nm)
into the small volume at the end of the cylinder (of the order of a few cubic
centimeters) and measuring the emitted red fluorescence (685nm) from
phytoplankton chlorophyll.
(2) turbidity or backscatter by shining a light source (660 nm)
into the same small volume at the end of the cylinder and measuring the
scattered light. This measurement is similar, but complimentary to the C-Star
measurement.
These parameters are of interest
because they tell us the concentration of phytoplankton (chlorophyll), the
concentration of carbon, and something about the nature of the particles
present. Some of these measurements are similar to the samples that have been
taken by MBARI and others since 1997, but the optical instruments will give us
full profiles instead of 8 discrete depths.
Each instrument will occupy one
connector on the SeaBird 911 unit. The C-Star will draw 30 mA and return one
channel of analog data (0 to 5 volts), while the FLNTU will draw 80 mA and
return 2 channels of analog data (0 to 5 volts), one for fluorescence and
another for turbidity (aka backscatter, bb). The sampling frequency of the instruments will likely be 8 Hz
(subject to confirmation with SeaBird). Pete Strutton will supply two cables
for each instrument (ie one
spare) and the configuration (pinouts) of these
cables will be worked out in consultation with SeaBird and WET Labs.
Ideally the C-Star will be mounted horizontally
near the bottom of the rosette, while the FLNTU will be mounted vertically with
the optics ‘looking’ down. The instruments do not require pumps or flow tubes –
they are both open path.
Pete will visit the Ka’imimoana prior to
GP5-05-KA and work with Shawn Gendron to attach the instruments to the CTD
rosette. Modifying the data acquisition software to accommodate the three new
data streams will require communication with Kristy McTaggart and SeaBird. Pete
has some experience with this process and Kristy has offered to supply new
configuration files and generally help the process. SeaBird can help too. The
real time data acquisition display will be modified so that Shawn can monitor
the data from the optical instruments, if he wants to. Pete will supply all
necessary hardware. Pete’s student (Wiley Evans) will participate in GP5-05-KA
and will be familiar with the instruments. Data dissemination is being worked
out between Pete, Kristy and Greg.
To get the most scientific benefit from the data
collected, calibration samples for chlorophyll and POC should be taken
occasionally. For the foreseeable future, MBARI and Mike Behrenfeld at OSU will
take samples along the 125°W, 140°W, 155°W and 170°W TAO lines. Pete is working
on funding that would support measurements on the other TAO lines, but for the
time being no samples will be taken on the 95°W, 110°W, 180° and 165°E lines.
That is, there is no expectation that Shawn or PMEL personnel will do anything
for these instruments when MBARI/OSU personnel are not present.
MBARI/OSU personnel will clean the optics
occasionally and obtain a ‘full scale’ reading from the C-Star once or twice
per cruise. The latter involves blocking the path between the source and
detector while the CTD is on deck and reading the output through the SeaBird
data acquisition software.
Pete Strutton will arrange for calibration of
the instruments on an annual basis. No effort (removing, shipping, attaching)
on the part of the survey tech is requested/expected.
Instruments of this type, particularly the
C-Star, are standard on most UNOLS vessels and have a very good track record
for reliability. If problems occur they are most likely to be with the cables.
As described above spares will be included and replaced if failures occur. The
instruments are rated to 6000m, so will not need to be removed for deep CTDs.
If a failure occurs, there is no expectation
that the survey tech will trouble shoot it. The best procedure to follow is (1)
disconnect the cable at both the instrument and SeaBird 911 end, (2) dummy off
the connectors at both the instrument and SeaBird 911 end, and, if possible (3)
remove the instrument from the rosette.

requirements imposed by NOAA. The
Chief Scientist shall be responsible for complying with MOCDOC 15, Fleet
Environmental Compliance #07, Hazardous Material and Hazardous Waste Management
Requirements for Visiting Scientists, released July 2002. The MOCDOC web site address is:
By Federal regulations and NOAA Marine and
Aviation Operations policy, the ship may not sail without a complete inventory
of all hazardous materials by name and the anticipated quantity brought aboard,
MSDS and appropriate neutralizing agents, buffers, and/or absorbents in amounts
adequate to address spills of a size equal to the amount of chemicals brought
aboard and a chemical hygiene plan. The
Chief Scientist shall account for the amount of hazardous material arriving and
leaving the vessel. NOAA Ship KA’IMIMOANA Environmental Compliance Officer will work with the Chief
Scientist to ensure that this management policy is properly executed, and that
any problems are brought promptly to the attention of the Commanding Officer.
3.1 Material Safety Data Sheet (MSDS)
All hazardous materials require a Material Safety Data Sheet
(MSDS). Copies of all MSDS’s shall be
forwarded to the ship at least two weeks prior to sailing. The Chief Scientist shall have copies of each
MSDS available when the hazardous materials are loaded aboard. Hazardous material for which the MSDS is not
provided will not be loaded aboard.
3.2 HAZMAT Inventory
The Chief Scientist will complete a local inventory form, provided
by the Commanding Officer, indicating the amount of each material brought
onboard, and for which the Chief Scientist is responsible. This inventory shall be updated at departure,
accounting for the amount of material being removed, as well as the amount
consumed in science operations and the amount being removed in the form of
waste.
3.3 HAZMAT Locker
The ship’s dedicated HAZMAT Locker contains two 45-gallon capacity
flammable cabinets and one 22-gallon capacity flammable cabinet, plus some
available storage on the deck. Unless
there are dedicated storage lockers (meeting OSHA/NFPA standards) in each van,
all HAZMAT, except small amounts for ready use, must be stored in the HAZMAT
Locker.
3.4 HAZMAT Spill Response
The scientific party, under the supervision of the Chief
Scientist, shall be prepared to respond fully to emergencies involving spills
of any mission HAZMAT. This includes
providing properly-trained personnel for response, as well as the necessary
neutralizing chemicals and clean-up materials.
Ship’s personnel are not first responders and will act in a support role
only, in the event of a spill.
3.5 Responsibilities
The Chief Scientist is directly responsible for the proper
handling, both administrative and physical, of all scientific party hazardous
wastes. No liquid wastes shall be
introduced into the ship’s drainage system. No solid waste material shall be placed in the
ship’s garbage. Ancillary Projects shall properly train
their personnel in hazardous material handling and disposal.
