Optimum Start Date:
|
7/1/2019 |
Dates to Avoid: |
There is a narrow weather window in the North Atlantic with optimal days with fewest storms in the month of July. We could carry out the cruise in either 2018 or 2019 within the mid-June to mid-August weather window. |

 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)?
|
Yes |
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.) |
We request use of the Bell BGM-3 gravimenter provided by the WHOI Potential Field Equipment Pool Facility, which may require an ITAR licence. |

Reykjavik, Iceland |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Reykjavik, Iceland is a main port close to the study area with good facilities for international shipping, fueling, and provisioning the ship. |

Explanation of Science Party Requirements and Technician Requirements |
Science party consists of two investigators, a collaborating scientist from Iceland, 9 student watchstanders and two shiboard technicians. We plan to operate three science watches led by a senior scientist, with three student watchstanders and two technicians to provide 24-hour operations during the cruise. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Operator provided instruments include towed magnetometer and a spare, ship gravimenter (Bell BGM-3), hull mounted 12 kHz multibeam system (Kongsberg Simrad EM122 or better) and sub-bottom sediment profiler, which should be synchronized to work simultaneously with the multibeam system. We also request a sufficent number of deep XBT's to provide daily water column sound velocity profiles to calibrate the multibeam system. If the ADCP system is working we request that it be run continuously to provide valuable ancilliary data on currents, but is not critical for our planned operations.

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
Our objective is a continuous underway geophysical survey that will be conducted at least at 10 knots over 35 days collecting simultaneous multibeam bathymetry, magnetics, gravity and sub-bottom sediment profiler data. |
