Summary of Field Work: |
2018: Use JASON II ROV system to conduct temperature survey near the seafloor in the ASHES hydrothermal vent field in the Axial Caldera on the Juan de Fuca ridge off the coast of Oregon. This temperature survey would be used to determine the location for installing the COVIS sonar system.
2018: Use JASON II ROV system to do the following:
- Install COVIS sonar system at ASHES site
- Install 50m cable and connect COVIS to OOI-CA seafloor junction box
- Install thermistor arrays
2022: Use JASON ROV to recover COVIS sonar system |
|
Summary of Facility Requirements: |
We will require the JASON II ROV system equipped for use in 1500m water depth |

Repeating Cruise?
(within same year) |
Yes |
Interval: |
1-4 weeks |
# of Cruises: |
2 |
|
|
Description of Repeating cruise requirements: |
The first cruise would require the ship for 1 day and would use JASON to do a 8 hour temperature survey near seafloor in the ASHES hydrothermal vent area of the Juan de Fuca Ridge off the coast of Oregon. This survey must occur in advance of the COVIS installation, as the results of the survey will be used to finalize the preferred location for COVIS. A minimum of 2 weeks processing time must be allowed between the survey and COVIS installation. The survey can occur any time in the 2017 or 2018 field seasons prior to the OOI/RSN O&M cruise. If this survey occurs as part of the 2018 OOI/RSN O&M Cruise, it would need to take place on Leg 1 with COVIS installation occurring on subsequent Legs 2 or 3.”
The second cruise would require the ship and ROV for 2 days to do the following:
- install the COVIS sonar
- install a 50m cable with ROV-mateable connectors to connect the COVIS sonar to the OOI/CA/RSN Junction Box at ASHES
- install five thermistor arrays and make spot measurements of temperature and flow rates |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We need the JASON II ROV system to install COVIS and connect it to the OOI/CA/RSN observatory seafloor junction box so it wouldl be cost-effective solution is to use the R/V Thompson with JASON on-board during the annual OOI/CA/RSN maintenance cruise. |

Explanation of Science Party Requirements and Technician Requirements |
We will need 2 people in our science party - an engineer that is familiar with the operation and installation requirements for COVIS and a technician/student that is familiar with the operation of the flow meter that will be used to measure the vent vertical outflow velocity. |
