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) Underway Mapping
2.3.1 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.
2.3.2 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.
2.3.3 Mooring Sensor Swaps
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 subsurface MBARI bridle sensors will be swapped out (estimate six hours for operations). The 2S-170W Standard Atlas buoy will also be brought on deck and subsurface MBARI sensors swapped out (estimate six hours for operations).
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.

2.4 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.
Most often, drifter deployments are requested when crossing 00 30.0N, the Equator, and 00 30.0S. Drifter deployments are frequently requested at other locations along the cruise track. Typically, less than 12 deployments are requested on a cruise. The deployments should have little or no impact upon primary ship operations. Questions should be directed to:
Craig Engler, Global Drifter Center, NOAA/AOML
305-361-4439 (office) or 305-361-4392 (fax)
Craig.Engler@noaa.gov or http://www.aoml.noaa.gov/phod.html
2.5 Scripps Institute of Oceanography (SOI) SOLO Deep Ocean Drifters
Four "SOLO" (Sounding Oceanographic Lagrangian Observer) Drifters will be deployed along 155W at the following latitudes:
5N, 130'N, 130'S, and 5S
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.
3.0 Hazardous Materials
The Chief Scientist is responsible for the proper and safe storage of scientific hazardous material and complying with NC Instruction 6280B, Hazardous Materials and Hazardous Waste Policy, Guidance, and Training, dated May 8, 1991. This includes the requirement for the Chief Scientist to remove all scientific team hazardous materials and waste at the end of the cruise.
