Summary of Field Work: |
We plan to traverse an oceanic region that is approximately 2-5°N and 90°W to conduct benthic experiments and coring. The benthic experiments will include the deploying of benthic landers and benthic pore water samplers. |
|
Summary of Facility Requirements: |
We request a ship capable of a 21 day cruise in the tropical E. Pacific, departing from Panama or Costa Rica with a return to a similar port. |

Explanation of Science Party Requirements and Technician Requirements |
Science party will consist of coring, lander, pore water, CTD floating traps, benthic in situ microelectrodes and other ops teams. Will need favorable weather to conduct benthic work on wire. |
|
 Dynamic Positioning | ADCP | Multibeam |  Seismic |
| Dredging/Coring/Large Dia. Trawl Wire | Stern A-frame | Fiber Optic (.681) | 0.680 Coax Wire |
| SCUBA Diving | Radioisotope use - briefly describe | NO Radioisotope use/Natural level work | Other Operator Provided Inst. - Describe |
| 0 PI-Provided Vans - briefly describe | MOCNESS | | |
|
Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We will request a UNOLS cold van if not available on ship
We will use trawl wire to deploy multicores and need some deployments to stay undisturbed on bottom for 6-8 hours
We will use CTD as per ships ops
|
|
|
|
Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
Request 2 (two) multicores, one cold lab (to process sediment cores) and potentially a mooring spooler or can use ship's capstan for recovery of free vehicles and traps |
