Summary of Field Work: |
This project seeks to design, test, and deploy a one-way travel time ultra-short baseline (OWTT-USBL) navigation system capable of providing accurate positioning at depths up to 6000m while overcoming existing obstacles of immobility, cost, and/or power associated with existing underwater acoustic aiding methods such as LBL and conventional USBL. The project will: a) design and manufacture a novel acoustic array; b) field-test the array with representative attitude sensors.
Field work will have 2 parts:
1) The system will be installed on the Sentry AUV and tested at progressively deeper depths in both "on-bottom" and driving modes. Sentry's USBL system will be used to ground truth our measurements.
2) System will be installed on a glider and deployed for 1 week. LBL transponders will be deployed to provide ground truth. |
|
Summary of Facility Requirements: |
For field program (1): Sentry AUV and a ship suitable for Sentry ops. Will need high quality USBL at depths up to 5000m so the "large" USBL head will be required (as opposed to the small head installed on Atlantis). Deep CTD profiles will be required for characterizing acoustics. We will need to dangle acoustic transducers over the side and have access to ship's GPS feed.
For field program (2): West coast based ship capable of supporting glider ops. Will need to deploy and survey in LBL transponders. Deep CTD profiles will be required for characterizing acoustics. We will need to dangle acoustic transducers over the side and have access to ship's GPS feed. |

Dates to Avoid: |
Need to avoid poor weather off the Northwest Pacific Coast. Summer preferred. Earlier in summer is better as we have another program requiring gliders in Fall 2020. |

Explanation of Science Party Requirements and Technician Requirements |
Need to launch and recover UW Seaglider throughout the cruise. While the glider is operating we will have an acoustic transducer over the side. Will also need to launch and recover LBL transponders (science provided) as well as do CTD casts to 1000m. Operations will occur 24/hrs a day so ship technicians should be prepared to support this. |
