the 155°W and 170°W meridians and a repair of the mooring at 8°N, 180°W . The scientific complement will embark in
Honolulu, Hawaii and depart aboard KA’IMIMOANA on October 16, 2003 to commence operations as
listed in Appendix A. After completion
of operations, KA’IMIMOANA will proceed to Kwajalein, RMI arriving on or

2.0 OPERATIONS
Mooring Operations are scheduled to be conducted as shown in Appendix
A. Operations will be conducted from 8°N - 155°W to 8°S - 155°W and 8°S - 170°W to 8°N 170°W and then to 8°N 180°W enroute to Kwajalein . The
following mooring operations are anticipated, though the work may be changed by
direction of the Chief Scientist, in consultation with the Commanding Officer.

* These moorings have been deployed six
months. 2 Sites along 170W are
scheduled for recovery/deployment to rebalance spring/fall work. These sites could change in the event of
failures.
2.01 CTD
At a minimum, 1000 meter CTD casts shall be conducted at each mooring
site between 12° N and 8° 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:
- 1000m CTD’s at one degree latitude intervals between 12° N and 8° S , along the
ship's trackline.
- Extend 1000m CTD’s at mooring sites to a minimum of 3000m or a maximum
depth of 200m from bottom. 4 to 6 deep
casts are optimal, occurring at the beginning and end of the cruise as well as
at both equatorial sites.
- 1000m CTD’s every one‑half degree of latitude between 3°N and 3°S
- Additional calibration CTD’s to be determined by Chief Scientist.
MBARI personnel will be available to assist the survey technician with
CTD casts and running salinities.
2.02 Monterey Bay Aquarium
Research Institute (MBARI) Chlorophyll and Nutrients
Phytoplankton biomass work consisting of chlorophyll extractions and
nutrients samples will collected from CTD rosette 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. This
requires use of the sink/bench area of the wet lab for filtration purposes. Chlorophyll samples will be measured
on-board using a bench-top fluorometer which will require use of the
salinometer room. Nutrient samples (sea
water) will be stored in the science hold and off-loaded upon return.
MBARI personnel and the barnacle observer will conduct this work.
2.03 Bloomsburg University Barnacle Census
Barnacles will be
collected in accordance with TAO Standard Operating Instructions. Sea spiders will also be collected in a
similar manner by the barnacle observer on behalf of Lanna Cheng of Scripps. The sea spiders will be preserved in 70%
ethanol. A pre and post cruise
inventory of Hazardous Materials (Hazmat) brought aboard and offloaded from the
ship will be given to the Chief Scientist and Commanding Officer. All Hazardous Materials will be properly
labeled as to content, Hazmat classification and cruise number. All hazardous materials associated with the
barnacle work are to be removed from the ship following the 165E/180W leg in
Honolulu.
2.04 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 which 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
TBA
The deployments
should have little or no impact upon primary ship operations. Questions should be directed to:

number of floats
or a float fails its initialization, the first deployments
to omit are
(9. 1N 170W) .

2.06 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 8N, 4N, 0, 4S and 8S along the 155W and 170W lines. Automated sampling cycle is approximately 5
hours. It is anticipated that the
Survey Technician will perform the maintenance tasks.

2.07 Dissolved inorganic carbon analysis
(DIC)
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 mercury chloride solution will be provided by Scripps institute of Oceanography. Samples for GP3 and GP4 will be stored on board until the ship returns to Honolulu. Cathy Cosca from PMEL will ship the samples to Scripps when she comes to work on the underway Co2 system in August. It is anticipated that the survey technician, together with MBARI personnel will take the samples. A small bench-top drill press will be shipped to the ship to assist with the bottle capping process.
