CRUISE DESCRIPTION

General guidelines are contained in the TAO Program Standard Operating Instructions for NOAA Ship KA'IMIMOANA dated December 30, 1998.

Cruise Objective and Plan:

The objective of this cruise is the maintenance of the TAO Array along the 155W and 170W meridians. The scientific complement will embark in Honolulu, Hawaii, load mooring equipment and then depart aboard KA'IMIMOANA on October 20,1999 to commence operations as listed in Appendix A. After completion of operations, KA'IMIMOANA will proceed to Suva, Fiji arriving on or about November 14, 1999. All dates and times referred to in these cruise instructions are in Hawaiian Standard Time (HST).

1.0 PERSONNEL

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.

Participating Scientists

1. Linda Stratton F USA NOAA/PMEL

2. Brian Powers M USA NOAA/PMEL

3. Peter Strutton M USA Monterey Bay Aquarium Research Institute (MBARI)

4. Brian Schlining M USA Monterey Bay Aquarium Research Institute (MBARI)

2.0 OPERATIONS

The cruise track and details of station work are summarized in Appendices A and B. Underway observations are described in section 2.1 of the TAO Standard Operating Instructions. Upon completion of the cruise the vessel will provide to the Chief Scientist an operations spreadsheet (similar to Appendix A) with times and speeds made good for the entire cruise.

2.1 Mooring Operations

Mooring Operations are scheduled to be conducted as shown in Appendix A. Operations will be conducted from 8N - 155W to 8S - 155W and thence to 0 - 170W to 8S -170W. The following mooring operations are anticipated, though the work may be changed by direction of the Chief Scientist; in consultation, with the Commanding Officer.

Location Mooring Type Operation

8N 155W Standard ATLAS Visit.

5N 155W Standard ATLAS Visit.

2N 155W ATLAS II - Taut Visit (Insert/Fairings).

0 155W Standard ATLAS Recover (with MBARI sensors).

ATLAS II - Taut Deploy (Insert/Fairings).

2S 155W Standard ATLAS Visit.

5S 155W Standard ATLAS Recover/Deploy.

8S 155W Standard ATLAS Recover/Deploy.

Location Mooring Type Operation

0 170W Standard ATLAS Visit.

Subsurface ADCP (Note in vicinity)

2S 170W Standard ATLAS Recover/Deploy (with MBARI sensors).

ATLAS II - RevCat Visit (no subsurface).

5S 170W Standard ATLAS Visit.

8S 170W Standard ATLAS Recover/Deploy.

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, salinity, fluorescence, and nitrate) will be on-line and running throughout this cruise. Phytoplankton work will also be conducted, consisting of chlorophyll and nutrient extractions from CTD samples. This will require use of the sink/bench area of the wet lab.

Productivity measurements will be conducted using a carbon isotope method. Samples will be read in a Liquid Scintillation Counter (LSC). The LSC's dimensions are three feet square and the instrument weighs approximately 200 lbs. Ideal location would be within the wet laboratory.

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:

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.

3.1 Ancillary Projects Hazardous Materials
