Summary of Field Work: |
Initial proof of concept will be performed during a 3 day leg on the R/V Gordon Sproul and involve tow body tests using the Liquid Robotics Wave Glider. The tow body will be an empty, ballasted frame to mitigate against risk of tow package loss.
Concurrent to at-sea tow testing, a complete acoustic system test will be performed in the San Diego Trough during this initial 3-day R/V Sproul cruise leg. Wave Glider and OBS sled packages will be deployed independently form the ship, where real-time communication and data transmission quality can be monitored and assessed. Both systems will have the WHOI modem module and transducer mounts. Upon completion of 7-days of on-bottom communication, station keeping, and data acquisition testing, Glider and OBS packages will be retrieved on a separate 1-day R/V Sproul cruise leg and returned to SIO to refine and optimize instrumentation.
Once a final tests and modifications are complete, we propose a 3-month full system ship-deployment test at 4000m (full ocean depth). Using the R/V New Horizon on a 3-day deployment cruise we can access a 4km water depth in less than a day of transit (~170nm offshore San Diego). This location is outside of the protected Southern California Bight, and therefore will provide in-situ testing of open ocean conditions near full ocean depth. This long-term recording test will identify longevity and long-term communication fidelity, as well as give and indication of system robustness, vulnerability to biofouling, and any corrosion issues. Upon the completion of the 3-month test the instruments will be retrieved (R/V New Horizon), completing the ADDOSS POC design |
|
Summary of Facility Requirements: |
Initial proof of concept could be performed near shore on the R/V Gordon Sproul on an initial 3 day near shore cruise and a follow up 1 day acoustic testing cruise.
Full system testing would require the R/V New Horizon for a 3 day deployment cruise, and a 3 day recovery cruise. |
