Task Force Ocean Department Research Initiative: Supplemental support to conduct San Diego fieldwork with opto-acoustic drifter platforms
Abstract
An ongoing Task Force Ocean (TFO) Grant (ONR N00014-21-1-2953) is supporting the development of four buoyancy-adjustable drifter platforms that record optical and passive acoustic data for up to 72 hours at depths down to 1000 m. During a Sept. 2022 New EnglandSeamount research cruise on the R/V Endeavor, one prototype opto-acoustic drifter (called #SQUALL-E#) was deployed five times, but the expected arrival of Hurricane Fiona shortened the cruise by eight days, preventing a full engineering test of the system.This supplemental proposal will permit 8 days of additional field testing off the San Diego coast in Feb/March 2023 on the R/V Bob and Betty Beyster, including test deployments of all four prototypes. The engineering goals include testing software fixes for the buoyancycontroller and camera systems, testing additional types of acoustic vector sensors, and expanding the depth and duration tests of the four platforms. The tests will also permit the collection of high-quality data for collaborative research on ambient noise navigation and drifter #swarm# control algorithms. The work will permit the drifters to be fully developed and tested before the Fall 2023 TFO expedition.This abstract is publicly releasable
