Cruise Objective and Plan:
The objective of this cruise is the maintenance of the TAO Array along the 155 and 170W meridians. The scientific complement will embark in Honolulu, Hawaii and depart aboard KA'IMIMOANA on May 29, 2001 to commence operations as listed in Appendix A. After completion of operations, KA'IMIMOANA will proceed to Kwajalein Atoll, Republic of the Marshall Islands (RMI) arriving on or about June 29, 2001. All dates and times referred to in these cruise instructions are in Hawaiian Standard Time (HST).

1.1 CHIEF SCIENTIST AND PARTICIPATING SCIENTISTS:
Chief Scientist: Steve Kunze
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.

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.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.
2.3.2 Productivity Measurements (C-14)Productivity measurements will be conducted using a 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.
Samples will be read in a Liquid Scintillation Counter (LSC). The LSC will be set up within the wet laboratory.At the 0-155W and 2S-170W moorings an additional
six hours per site are required for
MBARI instrumentation swap outs. At 0-155W
the Taut-line Next-Gen buoy (with floatation Insert) will be brought on deck
while anchored and the MBARI bridle sensors will be swapped out. The upper 20m
of the mooring line will also be pulled aboard for sensor swaps (estimate six
hours for operations). The 2S-170W Standard
Atlas buoy will be brought on deck and MBARI bridle sensors swapped out.
If conditions permit these operations may be completed by divers.
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.

2.5 Scripps
Institute of Oceanography (SOI) SOLO Deep Ocean Drifters
11 "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 and Trace Metal Nutrients (Behrenfeld, Shea)
The fast repetition Rate
Fluorometer (FRR) and Trace Metal Nutrient sampling measurements will not be
conducted during KA-01-05, but a majority of the instruments will be brought
aboard and set up and/or stored
for use on the following leg, KA-01-06.
