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:
1) 1000m CTD's at one degree latitude intervals between 12 N and 8 S , along the ship's trackline.
2) Extend 1000m CTD's at mooring sites to a minimum of 3000m or a maximum depth of 200m from bottom.
3)1000m CTD's every one-half degree of latitude between 3 N and 3 S
4)Additional calibration CTD's to be determined by 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) Underway Mapping
The MBARI underway-mapping system (temperature and fluorescence) will be on-line and running throughout this cruise. Phytoplankton work consisting of chlorophyll and nutrients extractions will extracted from 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. This requires use of the sink/bench area of the wet lab.

2.5
Scripps Institute
of Oceanography (SOI) SOLO Deep Ocean Drifters
15 "SOLO" (Sounding Oceanographic Lagrangian Observer) Drifters will be deployed along the cruise track. Deployment locations are listed in section 2.0 and in Appendix A. Each SOLO float is self contained with minimal preparation and can be deployed at full speed. It is requested that deployments be made as KA'IMIMOANA is departing the above stations.
2.6 Fluorometer (Behrenfeld/Shea)
2.6.1 Fast Repetition Rate Fluorometer
The core measurement for this NASA research project is the analysis of variable
fluorescence using a bench-top fast repetition rate fluorometer (FRR). The FRR
measurements are conducted using the ship's continuous flow through of clean
uncontaminated sea water (requirement: .200mL per minute). During the September
2000 cruise (KA-00-07), we set up theFRR on a homemade bench near the sink in
the wet-lab. This was an ideal location for the instrument because it allows
for disposal of the measured seawater. Other locations could also work equally
well.
We plan to conduct FRR measurements on cruises: KA-01-04 (San Diego-Honolulu transit) and KA-01-06 (165E/180) . The FRR measurements should require little or no assistance from ship personnel, nor interfere with the ship's transit and/or TAO mooring operations.
2.6.2 Solar Irradiance
A Licor Data Logger (LDL) will be
used to simultaneously 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. During KA-00-07, we found that the overhead of the starboard aft control
station was an ideal location for the Licor sensor. The sensor is very small
(1" x 7/8") and the LDL recorder is 9" x 5". Solar irradiance data will be collected
on KA-01-04 and -06.
2.6.3 Ship Data
Continuously logging of
the following six second averaged data, throughout the cruise provided to the
FRR laptop computer from KA'IMIMOANA's Scientific Computer System (SCS): (a)
GPS time (b) GPS latitude (c) GPS longitude (d) Seawater temperature (e) Seawater
salinity (f) Solar irradiance The solar irradiance is extremely useful for merging
the data from NASA's FRR instruments with KA'IMIMOANA's SCS data.

2.7 Trace Metal Nutrient Analysis (Worthington)
2.7.1 Macro- and Micro-Nutrients
Analysis
Samples for macro- and micro-nutrients analysis will be collected in a portable
clean bench installed in the wet lab. The clean bench will be plumbed with a
trace-metal-clean tube that runs from the lab to the lower aft deck and terminates
at a depressor. The depressor with tubing is towed away from the ship''s wake
for approximately 15 to 20 minutes (including deployment and recovery time)
and clean sea water is pumped from the sampling system to the wet-lab with a
compressor on the lower work deck. As time permits, the system will be towed
at the mooring and CTD stations. During the September cruise in 2000, the system
was towed from the port aft crane. Deployment and recovery requires stopping
the ship, while towing can be done at up to 10 knots. Final rigging will be
determined prior to departure from port after consultation with the Commanding
Officer and/or his shipboard designate. Prior to mooring stations the towed
fish will be brought aboard and secured.
Seawater flow rate is 4 liters/min, the pump will require a quick release type connection to and continuous use of ship's compressed air (2-3 SCPM at 80psi.) while the unit is sampling. The in-water component of the system consists of a 3/8" Kevlar strength member with a 1/2" OD polyethylene tubing (with a thin Teflon liner) in parallel. The Kevlar and poly tubing are joined every 1.5 feet by cable ties and tape. The paired line runs through the sheave on the crane. At the end of the tube is a plastic torpedo shaped fish through which the plastic tube terminates, with the tube opening at the nose of the torpedo. The Kevlar passes through the middle of the torpedo, similar to the axis of a weathervane, and is shackled to the fiberglass "bat-wing" depressor about 1 meter below the torpedo. The internally weighted depressor (40 lbs.) keeps the line tight, pulling the fish down into the water to decrease the towing angle. The torpedo typically rides about 1-2m under the water surface. At 9 knots the horizontal towing force is approximately 1000 lbs., with momentary increases to 2000 lbs in high sea state.
2.7.2 Enrichment Experiments
In addition samples of
the collected seawater will also be stored in four six-liter carboys for enrichment
experiments, which involve a 20-hour incubation period in a water bath.
2.8 JAMSTEC Subsurface ADCP recovery (Takao)
A subsurface ADCP mooring deployed
by JAMSTEC will be recovered. The mooring location is 0 0.15'N 165 16.82'E,
approximately 8 nm east of the PMEL subsurface ADCP mooring. The Principle Investigator
for this project is
