Summary of Field Work: |
Coastal expedition to Guianas mudbanks region (Guyana, Suriname, French Guiana, Brazil) to collect suspended sediment, water samples, and multicores at 5 cross-shelf transects (maximum 80 nm linear distance of transects). |
|
Summary of Facility Requirements: |
This expedition will be to the coastal waters of the Guianas coast, the NE coast of S. American defined by the northern divide between rivers flowing into the Amazon and those flowing directly to the Atlantic Ocean. The entire coast lies between the Orinoco River and Amazon River mouths. The target of the expedition is the mobile mudbank complex of constantly re-suspended Amazon muds that emanate from the Amazon delta northwestward along the coast. As such, we request a UNOLS with shallow draft capabilities in order to access the shelf waters we wish to sample. The following facilities will be needed:
-Rosette sampler (Niskins + CTD, transmissivity, fluorescence, O2)
-Multicore (8-tube if launched from ship, 3-4 cores modified smaller versions possible if to be launched from work boats in case where ship is not able to access mudbanks (<10m water depth)
-Bottom sediment grab or box core
-Wetlab facilties for winkler titrations, water sample preparation, and porewater extraction
-Freezer and refrigeration for core and sample storage
-**Workspaces free of radiocarbon contamination in excess of natural levels** Our work will center on radiocarbon measurements, and thus we want to make sure that the latest swab report is clean. |
|
Summary of other requirements and comments: |
As stated above, the two most important facets of this request are:
1. that the ship is able to access shallow shelf waters in a dynamic environment. Typically work will be conducted in waters less than 10m depth. If the main ship cannot accommodate this, it will be necessary to have workboats that can at least perform sediment bottom grabs if not modified 3-4 tube multicoring
2. The ship will have to possess a clean SWAB test and no record of radio-isotope use after the most recent SWAB test. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Ship choice: The R/V F.G. Walton Smith is the shallowest draft of the UNOLS vessels in proximity to the location of our study. Although it is coastal/local class, it has worked in the Antilles before. It is operated by the University of Miami which has used its larger ships for research in this region within the last 30 years.
Number of Days: 10 days of transit time is estimated from Miami, ~2,200 nm passing through the western flank of the Bahamas, just north of Hispaniola and Cuba, through the Anegada Passage, and down the leeward side of the Lesser Antilles. The ship could proceed to the coastal waters of S. America through approach to either Trinidad or Barbabos (potentially for resupply), without much alteration to transit time. Mobilization could occur in Miami and demobilization in Kouru or Cayenne, French Guiana, or Belem, Brazil, if the ship is to take on another expedition before returning to home port. Regardless, the scientific crew would meet the ship in either Paramaribo, Kouru, or Cayenne, and disembark the ship in either Cayenne, Kouru, or Belem. |

Application for permits through institutional export control offices is performed during and subsequently to the submission of a proposal to NSF. This is in process, but I have answered no because it is not complete. |

French Guiana has the most advanced infrastructure in this area. It will likely be easiest for mobilization and re-stocking the ship. However, airfare is highly volatile, and at the time of this request it was difficult to find any flights for the scientific crew into Cayenne from TPA or MIA. Thus, the NSF budget for both collaborative institutions is with airfare to Paramaribo. Both Paramaribo and Cayenne are regional capitals and are politically stable for the last 10 years with the exception of a fuel strike in French Guiana in 2017. Other recent expeditions to this area (ANACONDA) have staged from Barbados on global class research vessels; we feel that with a shallow draft coastal class vessel, a port that is more proximal to the area of operations is desirable. |

Explanation of Science Party Requirements and Technician Requirements |
The scientific party necessary to conduct the sampling, preparation, and curation of the proposed activities can be small for this cruise, consisting of two PIs, students and technicians from the two research groups. All activities will on station will result in 4-6 hours of work (water sampling, titrations, filtrations, coring, extruding, preparing, and curating). Use of workboats to access shallower waters will add time to this estimate, but the hope is for most stations to be accessible directly from the Walton Smith. Technician requirements are minimal because, with a small scientific party, it is unlikely that we will need to perform 24 hour operations. |
