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. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Transit time is round-trip from Pago Pago, American Samoa. Ideally, this survey could be conducted while the ship is enroute to another location, potentially reducing travel time to a day or less. Ships with newer multibeam survey systems (e.g. EM120) such as the Melville will be able to conduct the survey in less time because of the greater swath-width to depth ratio for these systems. |

Honolulu, HI, USA |
None |
Apia, Western Samoa |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Since this is a mapping cruise and we will likely not have any science party members aboard, the start and end ports are arbitrary and should be ones that are the best logistically. Ideally, the survey could be conducted enroute to another location. |
