Summary of Field Work: |
We are proposing to study the volume, salt, heat and oxygen fluxes through the deep Samoan Passage using a lowered ADCP, profiling moorings and microstructure profilers provided by collaborator Carter. We are specifically interested in the role of internal waves and mixing in modifying these fluxes. Three cruises are planned: a short (4-day) mapping cruise in March 2011 to collect necessary bathymetry data, then two longer (40-day) survey cruises in March 2012 and Sept. 2013. A total of 9 moorings will be deployed during the first cruise, 4 of which will be deployed at the end of the cruise and will remain deployed until the second cruise. Five moorings are planned to be deployed during the second cruise. |
|
Summary of Facility Requirements: |
Global class research vessel capable of deploying full-depth (5000 m) moorings with deck space for gear associated with up to 5 moorings (anchors, floats, wire, etc.) and capable of being underway for 40 days w/out resupply. Deck space on an intermediate class ship is not sufficient to accomodate mooring gear. Also, global class ship must have TSE mooring winch or equivalent. Port facility with appropriate equip. for handling heavy mooring gear (forklifts) and capable of loading/storing a 40ft. intermodal container. |

Optimum Start Date:

7/20/2012 |
Dates to Avoid: |
Essential to science to have 16-20 months between two survey cruises for this research (this and 2013 cruise). Ex. cruise 1 July 2012, cruise 2 must be Nov 2013-Mar 2014. Slight preference for earlier as that would allow the TTIDE experiment to occur prior to Austral winter 2014. |

Explanation of Science Party Requirements and Technician Requirements |
*Request uplink-compatible SBE911 CTD, which will be used to send LADCP data up the wire in real-time.* We also will likely run the multibeam when transitting between sampling sites (filling holes of previous multibeam survey on KM)
Request res. tech for assistance with mooring deployment and recovery, shipboard CTDs, Lowered ADCP work, and assistance with recovering/deploying microstructure profiler. Computer tech also needed for potential computing needs. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Mooring deployment requires a global class ship with sufficient A-frame clearance and deck space to accomodate gear associated with 5 or more full-depth moorings (floats, glass, anchors, wire, spooler, etc.).
Deck space on an intermediate class ship is not sufficient to accomodate mooring gear. Also, global class ship must have TSE mooring winch or equivalent. Port facility with appropriate equip. for handling heavy mooring gear (forklifts) and capable of loading/storing a 40ft. intermodal container.
CTD with full ocean depth capacity (6000 m) necessary for CTD/ Lowered ADCP work.
