Summary of Field Work: |
2 cruises to the western equatorial Pacific will examine mixing in the equatorial thermocline. Cruise 1 will complete an ADCP survey along 156E together with LADCP/CTD stations every 0.5 degree, deploy 5 moorings each equipped with a McLane Moored Profiler, perform a repeated high spatial resolution LADCP/CTD/microstructure meridional section between the equator and 2N over 9 days, and a timeseries of LADCP/CTD/microstructure profiles at a fixed location over 7 days. Data from the ship's hull mounted ADCP will be recorded throughout the sampling period. Cruise 2 will repeat the ADCP/ LADCP/CTD/microstructure work of Cruise 1, and recover the moorings. The time between cruises will be 6 months. |
|
Summary of Facility Requirements: |
Ship's ADCP system (the 300kHz, 38kHZ combination on the Kilo Moana is preferred)
Ship's CTD (with dual C and T probes) and ancillary instruments
Small crane to aid deployment and recovered of tethered microstructure instrument
TSE mooring winch for mooring work
multibeam for bathymetry survey of mooring sites |

Repeating Cruise?
(within same year) |
Yes |
Interval: |
6 months |
# of Cruises: |
2 |
|
|
Description of Repeating cruise requirements: |
Cruise 1 is 28 days (inc. 2 days transit). Moorings deployed. Batteries of moored profilers will last 6 months. Deployment is preferred in the boreal winter or summer so that the winter/summer difference in conditions is covered by the 6 month deployment.
Cruise 2 is 28 days (inc 2 days transit). Moorings recovered.
1 full day of loading and unloading is required for each cruise |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The Kilo Moana is the preferred ship because of its combination of 300kHz Workhouse and 38kHz Ocean Surveyor hull mounted ADCPs, giving good resolution in the surface layer and deep penetration. |
