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).

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.
