Summary of Field Work: |
Acquire approximately 1700-2000 line-km of multichannel seismic data with small airguns (USGS--Ruppel is expert at and will be fully responsible for obtaining the IHA, biological opinion, etc) to fill in the modern seismic data gap between just south of Hudson Canyon to approximately Currituck slide, from the outer shelf to 2500-3000 m water depth |
|
Summary of Facility Requirements: |
USGS will provide: GI-guns, 1 km streamer/birds and UNOLS-approved winch, compressors, sonobuoys, all acquisition computers, and EK60 transducer to be mounted in retractable keel.
Total weight is within limits for R/V Sharp fantail. |
|
Summary of other requirements and comments: |
prefer ship with stabilizers, ship based at Mid-Atlantic port (reduces transit) and ship not owned by NSF (so that NSF does not have to sign off on USGS NEPA) |

 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.) |
USGS is experienced with and will completely handle the IHA process (to comply with MMPA) and obtain a biological opinion (for ESA). The USGS will also be responsible for any CZMA consultations. PSVOs will be hired for this cruise. We expect the R/V Sharp to provide access to/cooperate with PSVOs stationed in the bridge or in another mutually agreeable spot. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Lewes, DE, USA |
Lewes, DE, USA |
Lewes, DE, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Request Lewes to avoid mob/demob costs. Intermediate port may be used for refueling. Anticipate needing to refuel twice due to fuel needs of compressors. Ideally one refuel in Norfolk @ NOAA dock and one in Lewes (possibly with crew switch at discretion of UDel). Lewes' charateristics: Port is conveniently about midway between northern/southern extent of surveys. |

Explanation of Science Party Requirements and Technician Requirements |
Science party will include contracted PSVOs. Professional PSVOs will likely be a requirement of the IHA the USGS obtains for this project.
USGS operations/technical personnel will run all seismic/EK60 operations. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We may need DP.
We do not require *shared use* equipment. We will provide our own seismic equipment. We are not reliant on UNOLS or the OBS facility for our seismic equipment. The availability of USGS equipment and personnel does affect scheduling on our side, since we cannot put the program to sea in May or June.
Due to needing fantail space for compressors and winches, we will likely sail without the USGS data acquisition van.
We are borrowing some Scripps equipment that is coming off the Atlantis in Woods Hole (Mitch Lyle's cruise) in late July. Thus, we cannot sail until after 1 August, 2018.
