Summary of Field Work: |
Project will install Phase-3 of the ALOHA Cabled Observatory (ACO) and experiments.
The junction box pressure case with hydrophone experiment module (HEM) and seawater return will be deployed first and connected to the sea cable termination with JASON. After successful operation is verified, the main observatory node (~2000 lb) will be lowered. JASON will unplug the HEM from the junction box, plug the node into the junction box, and the HEM into the node. The video camera sled will be moved from the node frame to the nearby seafloor. In a subsequent operation, the 200m high thermistor array/acoustic modem (TAAM) mooring system will be deployed, lowered from the ship to a location 50 m from the node. JASON will unspool cable from the base of the TAAM mooring and connect to the node. |
|
Summary of Facility Requirements: |
Class-A ship (Kilo-Moana, Thompson or larger), JASON-2 or equivalent (work at 4720 m). Deck space for JASON vans and deck equipment. Need small mooring winch (mooring 200 m long, anchor first). Room for science party of at least 22. |
|
Summary of other requirements and comments: |
Cruise TGT226 in October 2008 attempted installation but was unsuccessful because of failure of commercially supplied optical cabling and connectors. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
May - June have the best combination of weather and seas for this area, increasing probability of success.
We are amenable working with two other investigators, J. Sinton and A. Bowen, who have proposed close-by/related work. |

Explanation of Science Party Requirements and Technician Requirements |
Require JASON ops and heavy lift (2000 lbs) at 5 km depth.
Need to identify a small winch to deploy the 300 m long thermistor array/acoustic modem (TAAM) mooring. Once the mooring is over the side (anchor first), load would be transferred to the trawl winch. |
