Summary of Field Work: |
Geophysical surveying of portions of the southern Argentine continental slope and collecting sediment cores for paleoceanography and marine geology research, both late Quaternary paleoceanography and determining locations for proposed IODP drill sites. |
|
Summary of Facility Requirements: |
Ship with CTD, multibeam sonar, and subbottom profiler capable of collecting data in water depths that span the continental slope of southern Argentina. Ability to collect high-resolution 2D multichannel seismic profiles and ability to collect 4-inch ID piston and gravity cores, and multicores. |

Optimum Start Date:
|
2/1/2019 |
Dates to Avoid: |
We will revise dates as soon as Argentine colleagues confirm times of year that have either particularly good or bad sea states when working off shore of southern Argentina. Also, must allow time to obtain marine mammal permit for using multichannel seismic system. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Preliminary ship time estimate presumes transit to/from Buenos Aires. Time includes seismic survey followed by sediment coring and water sampling. The ship time esitmates are preliminary and will be adjusted following discussions with multichannel seismic team, coring team, and revisions of project team. |

 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.) |
The Geometrics streamer used by the SIO multichannel system probably requires a permit -- we are asking SIO. |

|
Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Buenos Aires, Argentina |
None, |
Buenos Aires, Argentina |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Buenos Aires selected for ease of shipping and travel; of few other Argentine ports are closer -- we will investigate their feasibility. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Require multibeam sonar, subbottom profiler, and CTD. Capability of deploying MCS system and piston/muticoring systems. Refrigerated core storage and MSCL core logger if possible.

|
Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
Ship selection based on current understanding of capabilities.
We communicated with OSU and SIO regarding coring and Multichannel seismics, respectively. We understand from NSF that RV Langseth (and related MCS equipment?) not available for this project and we are not sure of status of WHOI coring group. SIO MCS group stated that they may need to gain access to portable compressor, depending on UNOLS ship scheduled. |
