Summary of Field Work: |
We will be conducting hydrocast surveys, radioisotope work, in situ benthic lander deployments, and sediment coring on the Louisiana Shelf in early fall 2016 and spring 2017. |
|
Summary of Facility Requirements: |
We will require use of a CTD, rosette and coring equipment for these cruise. Deck space will be required for storage, launch and recovery of the LSU benthic lander (Maiti Laboratory). Gravity cores and multi cores (provided by PI) will be sampled per cruise. We will be using radioisotope for tracing silicon uptake and production (radioisotope van required). Because of the cruise plan, samples must be incubated on deck; incubators will be brought by the science party and plumbed to ship's seawater system. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The R/V Pelican’s home port is Cocodrie, LA, very near the sample area. This vessel has the capabilities necessary to meet the scientific objectives including use of radioactive materials, gravity, multi core equipment, deck space for incubators (with flowing seawater), and the capability to launch and recover a benthic lander. |

Explanation of Science Party Requirements and Technician Requirements |
The science party will include members of the Chief Scientist's and collaborator's
laboratories. Operations will be conduced around the clock on shifts in order to complete the science plan. Thus two operator provided technicians will be required. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We require the capability to do coring (multi core) and radioisotope usage. The R/V Pelican's coring equipment (8-spot multi core and gravity core) will be sufficient for our needs. Isotopes 32Si (daughter 32P) will be used. A benthic lander will be deployed and recovered, the Pelican has done this successfully for this specific instrument during other cruises.

|
Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
Radioisotope van will need to be procured if R/V Pelican does not have one dedicated for ship use at their marine facility (LUMCON). We will also require a multi core system (8 spot). |
