Summary of Field Work: |
This work aims to test the hypothesis that benthic fluxes of dissolved rare earth elements control the neodymium isotopic signature of deep water. This work requires intensive pore water sampling via multicorers and water column sampling via Niskin bottle and CTD at four stations in the Pacific at depths ranging from ~3000m to ~5000m. |
|
Summary of Facility Requirements: |
Rosette (Large volume Niskin bottles are best) with CTD
Multi-corer with side-mounted Niskin
Gravity Corer
Suitable-diameter wires for rosette and corers
Cold van for sediment sampling
Deck space and A-frame (or other) for deployments/recovery
We also request multi-beam and chirp sub-bottom. |
|
Summary of other requirements and comments: |
We hope to run the CTD/rosette casts while processing sediment from the multi-corer. Thus, we would ideally have two wires.
We would greatly appreciate two techs: one for the Niskin/CTD work and one for the sediment sampling; the sediment sampling technician should be part of the NORCOR facility at Oregon State University
Our main concern is a short cruise with lots of wire time (deep water) to try and recover pristine multicores... the stability of the ship is critical to avoid "bouncing" the corer. (Any extra ship days we might be able to acquire would be great too!) |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We hope to do deep multi-corer work, which is optimally done under calm conditions. The expedition has ambitious work planned for its duration, such that wire time spent on lander deployment and recovery will be critical. |

requirements that could affect choice
of ship in scheduling. |
We are requesting a multi-corer, gravity corer, Rosette/CTD. We would like to run the Rosette/CTD while sampling the multicorer sediments, thus request two lines.
