1.1 CHIEF SCIENTIST AND PARTICIPATING SCIENTISTS:
Chief Scientist: Margie McCarty
The Chief Scientist is authorized to revise or alter the scientific portion of the cruise plan as work progresses provided that, after consultation with the Commanding Officer, it is ascertained that the proposed changes will not: (1) jeopardize the safety of personnel or the ship; (2) exceed the overall time allotted for the cruise; (3) result in undue additional expenses; (4) alter the general intent of these instructions. A list of participating scientists follows in this set of specific cruise instructions. All participating scientists will submit a medical history form and be medically approved before embarking.

2.0 OPERATIONS
Mooring Operations are scheduled to be conducted as shown in Appendix A. Operations will be conducted from 8N - 155 to 8S - 155 and thence to 8S - 170W to 8N -170W and then to 8N -180 in route 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.

2.1 CTD
At a minimum, 1000 meter CTD casts shall be
conducted at each mooring site between 8 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:
If the time required for a CTD disrupts the
required daylight hours for a mooring operation or would delay the ship from
arriving in port on schedule, the Commanding Officer may omit a CTD, after consulting
with the Chief Scientist.
2.2 Bloomsburg
University Barnacle Census
Barnacles will be collected in accordance with TAO Standard Operating Instructions. 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.
2.3 Monterey Bay Aquarium Research Institute (MBARI)
2.3.1 Phytoplankton
Biomass and Nutrient Analysis
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
2.3.2 Productivity
Measurements (C-14)
Phytoplankton productivity measurements will
be conducted using a radioactive carbon isotope method (C14). MBARI is a U.S.
Nuclear Regulatory Commission (NRC) California State Licensee (not applicable
outside of California State waters) and operates under a NRC-241 (Report of
Proposed Activities in Non-Agreement States) permit. A copy of the current license
and NRC-241 2000 permit will be provided to the Commanding Officer prior to
the cruise. Water samples are collected at discreet depths, inoculated with
C14, incubated for 24 hours, filtered, and measured in a Liquid Scintillation
Counter (LSC). The LSC will be set up within the wet laboratory.
2.3.3 Mooring Sensor Swaps
At the 0-155W moorings an additional six hours are required for MBARI instrumentation swap outs.
At the 2S-170W mooring a complete turn-around including all MBARI optical instruments will be deployed.
2.3.4 SeaWiFS Profiling Multi-spectral Radiometer (SPMR)
Each day as close to local noon as possible
(between approximately 1000 and 1400 local) an optical cast will be conducted
using a SeaWiFS (Sea-viewing Wide Field-of-view Sensor) Profiling Multi-spectral
Radiometer (SPMR). This is a descendant of the Profiling Reflectance Radiometer
(PRR) that MBARI has used onboard KA'IMIMOANA
cruises since 1996. Operations will take approximately 30 minutes per station
and logistically should be completed; when possible, at CTD stations or between
mooring recovery/deployment operations. For more detailed information please
see:
http://seawifs.gsfc.nasa.gov/SEAWIFS.html
During transits, as time permits KA'IMIMOANA
will stop and hold station for the purpose of performing an SPMR cast. Ideally
it is preferred to conduct the SPMR cast at CTD stations when and where they
fall into the four hour local noon time frame. Besides the time savings, the
advantage of this dual operation is the ability to compare the optical data
with the CTD chlorophyll data which is invaluable to NOAA, MBARI, and the National
Aeronautics and Space Administration (NASA). The optical data is also used for
calibration and validation of SeaWiFS satellite measurements. MBARI's involvement
in this project falls under NASA's Sensor Intercomparison and Merger for Biological
and Interdisciplinary Oceanic Studies (SIMBIOS).
Along the equator, SeaWiFS passes over at
roughly local noon each day and MBARI coordinates receipt of high resolution
data over the ship's track along 155W and 170W. MBARI makes uses of approximately
30 seconds of SeaWiFS high resolution data available on the satellite each day.
This unique opportunity to collect this long term, time-series data at relatively
minimal additional costs is another invaluable service which KA'IMIMOANA
provides to the scientific community. For more detailed information please see:
2.4 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. Twelve drifters will be deployed at the following locations:
155: 3N, 1N, 0, 1S, 3S, 5S
170: 5N, 3N, 1N, 0, 1S, 3S
The deployments should have little or no impact
upon primary ship operations. Questions should be directed to:
Craig Engler, Global Drifter Center, NOAA/AOML

2.5 Scripps
Institute of Oceanography (SOI) SOLO Deep Ocean Drifters
No SOLO drifters will be deployed on this cruise.
2.6
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 just upon leaving each mooring location. Automated
sampling cycle is approximately 5 hours.
