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.

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

305-361-4439 (office) or 305-361-4392 (fax)

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.

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.
