KA-01-09 Kwajalein, RMI dep. 31 Oct 2001

Honolulu, Hi arr. 29 Nov 2001

The objective of this cruise is the maintenance of the TAO Array along the 165E and 180 meridians and recover the NMFS Bigeye mooring at location 20 36.00'N, 161 24.2'W. The scientific complement will embark in Kwajalein Atoll, Republic of the Marshall Islands (RMI) and depart aboard KA'IMIMOANA on October 31, 2001 to commence operations as listed in Appendix A. After completion of operations, KA'IMIMOANA will proceed to Honolulu, Hawaii arriving on or about November 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: Dave Zimmerman NOAA/PMEL

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.

2.0 OPERATIONS

Mooring Operations are scheduled to be conducted as shown in Appendix A. Operations will be conducted from 8N - 165E to 8S - 165E and thence to 8S - 180 to 8N -180. 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:

• 1000m CTD's at one degree latitude intervals between 12 N and 8 S , along the ship's trackline.



• Extend 1000m CTD's at mooring sites to a minimum of 3000m or a maximum depth of 200m from bottom.



• 1000m CTD's every one-half degree of latitude between 3N and 3S



• Additional calibration CTD's to be determined by 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

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.

2.4 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

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.
