CRUISE DESCRIPTION

General guidelines are contained in the TAO Program Standard Operating Instructions for NOAA Ship KA'IMIMOANA dated June 9, 2000.

Cruise Objective and Plan:


The objective of this cruise is the maintenance of the TAO Array along the 140W and 125W meridians. The scientific complement will embark in Honolulu, Hawaii and depart aboard KA'IMIMOANA on April 9, 2002 to commence operations as listed in Appendix A. After completion of operations, KA'IMIMOANA will proceed to Honolulu, Hawaii arriving on or about May12, 2002. There will be a short stop in Nuku Hiva, Marquises on or about April 27, 2002 with the possibility of embarking scientific personnel. 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:
Patrick Ahearn 4/9-4/27
Linda Stratton 4/27 - 5/12

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 - 125W to 8S - 125W, repair of DART mooring at 8.5S - 125W, a short stop in Marquises to embark scientific personnel and thence to 5S - 140W to 9N -140W. The following mooring operations are anticipated, though the work may be changed by direction of the Chief Scientist, in consultation with the Commanding Officer.

2.2 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.

2.4 Solar Irradiance

A Licor Data Logger (LDL) will be used to simultaneously log daily changes in solar irradiance. After consultation with the Field Operations Officer the solar sensor will be mounted in an acceptable exterior location free of shading. The LDL recorder will be enclosed from the weather, while the sensor itself is water resistant and will be exposed to the elements.

Continuously logging of the following six second averaged data, throughout the cruise provided to the FRR laptop computer:
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

1. Acetone 12 Liters MBARI
2. Hydrochloric Acid (HCL) 6 Liters MBARI
3. Formalin (50% stored in Wx deck Hazmat locker) 30 Liters Bloomsburg University
(diluted to 5% working solution for wet lab use)
