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)

Craig.Engler@noaa.gov or http://www.aoml.noaa.gov/

 

 

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.

1   2.0S  165.0E

2   5.0S  165.0E

3   8.0S  165.0E

4   8.0S  170.0E

5   8.0S  175.0E

6   8.0S  180.0E

7   5.0S  180.0E

8   2.0S  180.0E

9   2.0N  180.0E

10  5.0N  180.0E

11  8.0N  180.0E

12 11.5N  174.7W

13 13.5N  171.2W

14 15.5N  167.7W

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 to:

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.
