Summary of Field Work: |
Transit to the O2 minimum zone south of Baja (~ 22°N), conduct hydrographic surveys with CTD/Rosette and user-provided pump-profiling system, deploy autonomous floats, and finish with additional hydrographic surveying. |
|
Summary of Facility Requirements: |
CTD/Rosette with calibrated O2 sensor, FLNTU, and nitrate sensor
Ship mounted ADCP
Underway clean seawater system |
|
Summary of other requirements and comments: |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Departure from San Diego logistically most sensible regarding to transit to area and need to load equipment in a US port. Timing chosen to catch productive eddies forming south of Baja as well to avoid the hurricane season.
Ship size is suitable to open ocean needs as well as size of scientific party. |

 Important Info on Foreign Research Clearances
|
|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
San Diego, CA, USA |
None |
San Diego, CA, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Logistically close to operation area. As a US port, loading and unloading of instrumentation is much easier and reliable. Also home port for selected vessel. |

Explanation of Science Party Requirements and Technician Requirements |
Need a CTD/Rosette tech. CTD should have a calibrated O2 sensor and FLNTU. CTD operations will be 24hr so 2 Techs will be needed. Ship should have ADCP and one of the Techs should be capable of operating it.
We have a float operations group, a nuttrient and gas analysis group,, a metagenomics group, a carbonate system group, and a pump-profiling group (will bring pump-profiling system). |
