CRUISE
DESCRIPTION
General
guidelines are contained in the TAO Program Standard Operating Instructions for
NOAA Ship KA’IMIMOANA dated June 28,
2002.
Cruise Objective and Plan:
The
objective of this cruise is the maintenance of the TAO Array along the 165°E and 180°W
meridians. A PMEL test mooring will be
deployed at 8ºN 180ºW
and a NMFS Bigeye mooring will be recovered at 20º 36’N and 161º24.2’W. The ship will depart on July 19, 2004 to commence operations as
listed in Appendix A. After completion
of operations, KA’IMIMOANA will
proceed to Honolulu, Hawaii arriving on or about August 17, 2004. Prior to arrival in Honolulu, underway
fleet inspection activities will require approximately 5 hours. All dates and times referred to in these
cruise instructions are in Pacific Standard Time (PST).

2.0 OPERATIONS
Mooring
Operations are scheduled to be conducted as shown in Appendix A. Operations will be conducted from 8°N - 165°E to 8°S - 165°E and 8°S - 180°W to 8°N 180°W and via 20º 36’N and 161º24.2’W 8°N to
Honolulu. The following mooring
operations are anticipated, though the work may be changed by direction of the
Chief Scientist, in consultation with the Commanding Officer.

2.01
CTD
At
a minimum, 1000 meter CTD casts shall be conducted at each mooring site between
12° 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. 4 to 6 deep casts are
optimal, occurring at the beginning and end of the cruise as well as at both
equatorial sites.
-
1000m CTD’s every one‑half degree of latitude between 3°N and 3°S
-
Additional calibration CTD’s to be determined by Chief Scientist.
In
order to reduce the cost of standard water needed to calibrate CTD data, the number of salinity samples has been
reduced. PMEL proposes taking 8
samples per station instead of 12; not sampling ½ degree stations; and running
40 samples per standard instead of 36.
Questions regarding these revised procedures should be directed to
Kristy McTaggart.
2.02 Monterey
Bay Aquarium Research Institute (MBARI) Chlorophyll and Nutrients
Phytoplankton
biomass work consisting of chlorophyll extractions and nutrients samples will
be 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.
Nutrient
samples (sea water) will be stored in the science hold and off-loaded upon
return.
2.03 Bloomsburg
University Barnacle Census
No
barnacles will be collected on this cruise.
The Bloomsburg barnacle census project does not plan to participate on
TAO cruises in calendar year 2004.
2.04 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. Six AOML drifters
are scheduled at the following positions:
3N,
0, 3S along 180W

2.05 Pacific
Marine Environmetal Lab (PMEL) Argo profiling CTD floats
One Argo float
is scheduled for deployment on this cruise.
Individual deployment
positions can
be shifted by a degree or so along the ship track if more
convenient. Each float weighs about 56 lbs. Boxes are numbered sequentially in order
of deployment. The boxes weigh about
200 lbs. full and are 82” long x 17” high x 23” long. Boxes cannot be stored or transported on their small ends. The floats are sensitive to high
temperatures, so as space for a pair of floats becomes available
on the
computer lab rack, it will be desirable to move floats from the
next box to
the rack at the earliest convenient time.
A manual for
float-testing
and deployment has been sent to the
ship.
Float

2.06 Discrete 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 165ºE and 180ºW lines.
Automated sampling cycle is approximately 5 hours. It is anticipated that the Survey Technician
will perform the maintenance tasks. The

2.07 Dissolved inorganic carbon analysis (DIC)
A 0.5 liter sea water sample from surface CTD
casts will be taken and stored for later dissolved inorganic carbon
analysis. Sample jars and mercury
chloride solution will be provided by Scripps institute of Oceanography. It is anticipated that the survey technician, together with MBARI
personnel will take the samples. A
small bench-top drill press is installed on the ship to assist with the bottle
capping process. Samples will be
shipped to Scripps at the conclusion of GP4 in Honolulu. The contacts for this
project are:
