Summary of Field Work: |
Investigation of interactions between snail larvae and their bacterial symbionts, as well as investigation of the free-living symbiont populations, at six hydrothermal vent fields in the Lau back-arc basin (Tonga). The work will consist of ROV dives to collect snails, deploy and recover high-volume McLane pumps for larval collections, deploy and recover symbiont and larval collection devices, to collect microbial populations from the water column with an in situ filtration device, and collect substrata to analyze microbial populations. In addition, this project will also utilize the AUV Sentry outfitted with the larval collection device SYPRID to make larval collections in the water column. |
Summary of Facility Requirements: |
We request a global class ship (Thompson or Atlantis) that can accommodate both the deep submergence assets ROV Jason and AUV Sentry (plus the SYPRID sampler, an NDSF instrument for use with Sentry). We also request elevators for use with Jason. |

4/1/2020 |
Dates to Avoid: |
Cyclone season is November 1 - April 30 with peak January-March, and so we'd like to avoid this time period. Requesting April-May or September because of previous information about timing of reproduction in our target organisms. |

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.) |
Vent fields are found in Tongan waters, permit from them is required. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
Suva Harbor, Fiji Islands |
None, |
Suva Harbor, Fiji Islands |
Explanation/justification for requested ports and dates of intermediate stops or to list additional port stops |
Historically best port for mobilization and demobilization due to direct flights from mainland US, and only 2 day transit to most northern site. |
