8N 180W Standard ATLAS Repair (Wind)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: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.
A growth monitoring study of a selection of barnacles from the first recovered buoy may be conducted. Requirements include water from the uncontaminated seawater line (about 4 liters/minute) and a small space for the incubator (footprint of about 2 ft X 2.5 ft with two ½ inch hoses for overboard discharge) on the starboard weather deck in the CTD staging area, with constant supply of water from the uncontaminated seawater line.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.The 0-155W and 2S-170W moorings with MBARI sensors are both scheduled for full recovery and deployment.
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.htmlThe 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@noaa.gov or http://www.aoml.noaa.gov/
2.5 Scripps Institution of Oceanography (SIO) SOLO Deep Ocean DriftersFour "SOLO" (Sounding Oceanographic Lagrangian Observer) Drifters will be deployed at latitudes as specified in "Section 2.0 Operations" above.
The SOLO float are each self contained with minimal preparation and can be deployed at full speed. Whenever SOLO deployment sites coincide with Mooring or CTD operations, it is requested that SOLO deployments be made post mooring or CTD operations as KA'IMIMOANA departs the station.2.6.1 Description
A Portable Radiation Package (PRP) will be installed in an exposed place on the flying bridge or otherwise forward of the stack and will be operated during subsequent KA'IMIMOANA cruises to provide a continuous high-quality set of open ocean solar and long-wave radiation. This installation is part of the Brookhaven National Laboratory's Shipboard Oceanographic and Atmospheric Radiation (SOAR) program whereby a suite of ships across the world will be instrumented with the highest caliber of radiation instrumentation with the intent of collected a long-term global oceanic radiation data set.
The PRP is produced by Brookhaven National Laboratory (BNL) as part of the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program. The deployment of this instrument on KA'IMIMOANA is part of a long-term collaboration between ARM and NOAA to collect long-term data sets of atmospheric radiation as part of their common global climate research effort. KA'IMIMOANA's theater of operation (Equatorial Tropical Pacific) is of particular interest to ARM's research in tropical climate.The PRP will be installed on the KA'IMIMOANA prior
to its departure from Hawaii in October. A BNL engineer will work with the Chief
Scientist and the electronics technician on the KA'IMIMOANA to make
the installation. The PRP typically mounts on a length of 1.5 in. Aluminum schedule
40 pipe using hose clamps. Two shielded cables (Serial and power) are run from
the PRP to the P-DAC and power supply inside the ship. These cables each are
approximately .4" dia and can be as long as needed for a safe and professional
installation.
2.6.3 Operation and Routine Maintenance
During the cruise the PRP system is meant to be almost completely autonomous, requiring typically 10-20 minutes of time daily. The three optical domes on the PRP plate need to be wiped down on a regular basis. Thus part of the deployment consideration is to have a place where a person can reach the domes. Daily cleaning is best, but we have seen no degradation in performance even after several days without cleaning, especially if it has rained.
The zip disk on the P-DAC needs to be checked routinely to be sure it is not full. The data collection program must be checked to correct any time drift.1. All PRP raw data zip disks.
