The Wire Flyer is a ship-towed autonomous profiling vehicle that slides up and down on a standard towed 0.322 cable using controllable wings for propulsion. The vehicle is able to profile at commanded vertical speeds between 0 and about 2.5 meters per second while being towed at a speed of between 3 to 4 knots. The system can operate over specified depth bands in the water column (e.g., 400 to 800 meters) and is not restricted to the upper few hundred meters like other towed undulating systems. This project integrated a side-looking split-beam multi-frequency echo-sounder into the Wire Flyer towed profiling vehicle for the purpose of providing unprecedented acoustic and environmental sampling resolution of midwater biomass. The motivation for the project was to exploit the high spatial resolution sampling capability of the Wire Flyer vehicle and provide complementary acoustic data in regions of the water column that have been traditionally under sampled. Funding for this project was provided by NOAA Ocean Exploration via its Ocean Exploration Fiscal Year 2017 Funding Opportunity.
