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 140°W
and 125°W meridians and replace the
surface float of the DART mooring at 8.5°S, 125°W. The scientific complement will embark in
Honolulu, Hawaii and depart aboard KA’IMIMOANA on January 06, 2003 to
commence operations as listed in Appendix A.
A brief stop in Nuku Hiva, Marquises is planned for January 19 - 21,
2003. An acoustic release test is
proposed by PMEL/EDD if time allows.
After completion of operations, KA’IMIMOANA will proceed to San
Diego, CA arriving on or about February 10, 2003. All dates and times referred to in these cruise instructions are
in Hawaiian Standard Time (HST).

SCIENTISTS:
Chief
Scientist: Steve Kunze
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

EDD
Acoustic release test enroute to San Diego.
2.01 DART System
The
surface float and BPR of the DART system at 8.5S 125W will be changed out. It is requested that the mooring be brought
on deck with the anchor still attached and the surface floats exchanged. A complete surface buoy and tower will be
assembled in Honolulu prior to departure and stored on board until
deployment. The recovered surface &
sub-surface mooring can be broken down and stored in a convenient location to
lessen the impact on subsequent operations.
2.02 Engineering Development Division
Acoustic Release Test
The
objective of the test is to compare deck set signaling response with two brands
of acoustic releases. The test will
consist of a stand holding six acoustic releases which will be attached to the
CTD wire and lowered to a depth of at least 4000m. The stand is estimated to weigh 1000lbs. At various depths(1000m,2000m,3000m, etc), a
series of acoustic tests will be performed from the ship using various deck set
configurations and calibrated hydrophones. Time at each depth is estimated to
be 30min. Total time per cast is estimated to be 6 hours. Up to two casts are requested if time
allows. It is anticipated that the
casts would occur following the last CTD at 12N enroute to San Diego at any
location with sufficient water depth.
2.03
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:
-
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.
2.04 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.
2.05 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.
2.06 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.
Drifter deployment
locations have not yet been designated.
The ship’s survey tech is
requested to load the drifters from the University of Hawaii Marine Facility in
Honolulu onto the ship. The deployments
should have little or no impact upon primary ship operations. Questions should be directed to:

Drifter Center, NOAA/AOML

2.8 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 140W and 125W lines.
Automated sampling cycle is approximately 5 hours. It is anticipated that the Survey Technician
will perform the maintenance tasks.
