Summary of Field Work: |
Deployment and recovery of experimental wood packets at 4 locations in the northern Gulf of Mexico. |
|
Summary of Facility Requirements: |
We require a ship and submersible/ROV that will allow is to deploy experiments on the sea floor. Experiments will be recovered near the end of the project and require a ship and deep submergence vehicle capable of recovering the experiments. Experimental wood packets will be delivered and returned from ship to sea floor using a work basket on a winch or with the use of a free-fall elevator. |
|
Summary of other requirements and comments: |
A cold wet lab or walk in refrigerator for processing wood packets. Storage for ~100 5-gallon buckets that will hold final samples. |

Explanation of Science Party Requirements and Technician Requirements |
We require a sufficient number of scientists to help process wood packets and sediment cores once back on deck. Technician requirements are only necessary for standard submersible operations and launch/recovery of elevator or work basket. |

requirements that could affect choice
of ship in scheduling. |
We will need an elevator capable of transporting wood packets collected on sea floor to the surface. Three previous cruises for this project used a work basket lowered to the sea floor on a winch cable. The basket was unhooked from the cable for work on the bottom and reconnected for recovery at the end of the dive. We have an available basket if this type of operation is deemed necessary. The basket is rectangular in shape with an A-frame frame pick point and 2 independent doors on either side of a-frame. Total length is 1.96 meters, width of basket is 1.33 meters and height of basket enclosure is 0.96 meters. Maximum height at pick point is 1.85 meters. The basket lids on either side of the a-frame swivel on dual hinges and open fully to touch the a-frame where they are held in place by attached magnetic strips. Each lid has a width of 1.25 meters and a depth of 0.765 meters.
