Summary of Field Work: |
Marine and onshore/offshore seismic program offshore the North Island of New Zealand. The planned program involves seismic reflection and refraction data acquisition with ocean bottom seismometers (to be deployed by a second, non UNOLS ship). |
|
Summary of Facility Requirements: |
We need to use the R/V Langseth for crustal-scale seismic reflection and refraction work. We plan to use a 10 km-long streamer if feasible. We will also want to acquire other standard data sets (gravity, magnetics, swath bathymetry, sub-bottom profiler, XBT, etc.). |
|
Summary of other requirements and comments: |
It is very important to do this work during the New Zealand summer because there is a significant land component (onshore/offshore seismic). Therefore we strongly request time between January and April, but especially during February. |

|
Optimum Start Date:
|
11/1/2017 |
Dates to Avoid: |
We need to avoid May-November. This particularly important because there is a land component (onshore/offshore), and the land work will not be possible during much of the year. |

Earliest Start Date: |

Multi-Ship Op: |
Yes |
|
Latest Start Date: |

Other Ship(s): |
This is planned as a multi-ship program, with Langseth as the seismic/source ship and the other ship to deploy and recover OBSs. This will likely be a Japanese ship, but it could be a New Zealand ship. We do not plan that the other ship will be a UNOLS vessel. |

Description of Repeating cruise requirements: |
This is not a repeating cruise. The timing needs to be in the Austral summer or close to that due to weather conditions at sea and on land, as we plan for onshore/offshore recording. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The R/V Langseth is required because this is a crustal-scale seismic program. The timing is tide to availability of a second, non-UNOLS vessel, the R/V Tangaroa operated by the New Zealand organization NIWA. The Tangaroa will be available to deploy and recover OBSs for our project during November 2017. |

 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 |
| Questions about ITAR/EAR regulations?
|
Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
Foreign clearance will be required. This process is just starting. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Auckland, New Zealand |
None |
Wellington, New Zealand |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Auckland is convenient as a starting port because we plan to acquire data in the nearby Bay of Plenty. We plan to work our way south at the end of the cruise and so prefer to end in Wellington. |

Explanation of Science Party Requirements and Technician Requirements |
We will need a full complement of seismic data acquisition technicians for 2D deep seismic profiling. We will also have (at least) three international groups that will participate. *I am not sure if this is the meaning of the science teams--we will not be doing OBSs from the Langseth, or coring--just seismic. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We need the seismic capabilities of the R/V Langseth.
Other than that we will also want standard underway geophysics tools such as gravity, magnetics, multibeam bathymetry, and sub-buttom profiler.
