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 165E and 180 meridians. The scientific complement will embark in Kwajalein Atoll, Republic of the Marshall Islands (RMI) and depart aboard KA'IMIMOANA on July 1, 2002 to commence operations as listed in Appendix A. After completion of operations, KA'IMIMOANA will proceed to Honolulu, Hawaii arriving on or about July 29, 2002. 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: Andy Shepherd 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:
Barnacles will be collected in accordance with TAO Standard Operating Instructions. An inventory of Hazardous Materials (Hazmat) previously brought aboard for this project is on file with 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) Chlorophyll and Nutrients

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.

2.4 Atlantic Oceanographic and Meteorological Laboratory (AOML) Surface Drifters

No drifters will be deployed this 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


2.5 Scripps Institute of Oceanography (SOI) SOLO Deep Ocean Drifters

No SOLOS 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 at 8N, 4N, 0, 4S and 8S along the 165E and 180 lines. Automated sampling cycle is approximately 5 hours.

2.7 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. During KA-00-07, we found that the overhead of the starboard aft control station was an ideal location for the Licor sensor. The sensor is very small (1" x 7/8") and the LDL recorder is 9" x 5".

2.7.1 Ship Data

Continuously logging of the following six second averaged data, throughout the cruise provided to a laptop computer from KA'IMIMOANA's Scientific Computer System (SCS):

(a) GPS time

(b) GPS latitude

(c) GPS longitude

(d) Seawater temperature

(e) Seawater salinity

(f) Solar irradiance


The solar irradiance is extremely useful for merging the data from NASA's FRR instruments with KA'IMIMOANA's SCS data.

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.
