CRUISE DESCRIPTION
General guidelines are contained in the TAO
Program Standard Operating Instructions for NOAA Ship KA'IMIMOANA
dated June 9, 2000.
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 September 27, 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 October 28, 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: Linda Stratton
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.
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.
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.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:
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.

Dr. Peter Strutton, MBARI 831-775-1802 stpe@mbari.org2.4 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.Craig.Engler@noaa.gov or http://www.aoml.noaa.gov/
The Fast Repetition Rate Fluorometer (FRR) and Trace Metal Nutrient sampling operations will NOT be conducted.
