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 then to 8°N 180°W to deploy the Bigeye mooring .
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.
Patrick Hyder (NMFS) will be available to assist the survey technician
with CTD casts and running salinities.
2.02 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.
This work was to be done by the barnacle observer and may be shared
between the survey tech and scientific party.
2.03 Bloomsburg University Barnacle Census
Barnacles will
not be collected.
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 both 165°E and 180°W
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)

2.05 Scripps Institute of Oceanography
(SOI) SOLO Deep Ocean Drifters
14 SOLO drifters are scheduled for deployment on this cruise. The drifters are being shipped to Kwajalein directly from Scripps. The 14 planned float deployment locations are given below. As previously, deployment positions can be shifted in either direction to avoid mooring or station locations, meal times etc. Positions for the 3 floats on the transit leg to Hono are rough - use these approx lats if the ship track is different from our guess.

The
14 floats are all ballasted equally, meaning that any float can be deployed at
any position. If any float should fail its initialization, then omit the final
location. Questions should be directed

2.06 Discreet
gas sampler (Princeton University)
This equipment will not be aboard for this cruise.
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. Samples for GP3 and GP4 will be stored on board until the ship returns to Honolulu. Cathy Cosca from PMEL will ship the samples to Scripps when she comes to work on the underway Co2 system in August. It is anticipated that the survey technician, together with the scientific personnel will take the samples. A small bench-top drill press will be shipped to the ship to assist with the bottle capping process.
