Summary of Field Work: |
We propose geophysical surveys of select portions of the Line Island Ridge in order to select sites for sediment coring. We will be taking gravity, piston, and multi-cores and will also be making some water column measurements using CTD/Rosette. The aim of this work is to collect materials for paleoceanographic studies in this region. |
|
Summary of Facility Requirements: |
We request use of the Oregon StateUniversity Coring Group funded through the Ship Facilities Program of NSF. From the OSU group, we will need the large (4" diameter) piston corers, gravity corers, a multi-corer, MST, a refrigerated core container, standardcore supplies (core liners, storage tubes, etc.), standard sediment description instruments (microscope, etc.), a core cutter, and shipboard coring support. Our shipboard science party will be responsible for all analysis and processing of cores (including core cutting, labeling, and curation).
We will also need CTD/rosette, Multibeam swath bathymetry, compressor capability and high resolution MCS system, and Chirp seismic system.
Coring and surveying operations will be taking place around the clock. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Other ships (e.g. Knorr or Revelle) would also be appropriate for this work. Doing the work on the Langseth will enable a 2012 cruise.
OSU coring group may need additional mom/demob days to install equipment on the Marcus Langseth |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Honolulu, HI, USA |
None |
Honolulu, HI, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Honolulu is our preferred port. Other ports will require substantial additional cost for shipping cores and equipment. |
