The Waitt Institute CATALYST AUV Program

1. The Waitt Institute CATALYST AUV Program

2. …Making a Hydroid REMUS 6000 AUV System Accessible to the Ocean Science Community An easily integrated and highly mobile Dual AUV Toolkit that vastly improves survey efficiency, economizes ship-time, and adds ground-truthing capability without the need for equipment changeover

3. Two Complete AUVs (Ginger and Mary Ann) • Launch and Recovery System • Three custom outfitted 20’ ISO vans • Full Complement of Field Spares • 10 Deep Ocean Transponders • Data Analysis Suite

4. 120/410 kHz and 230/540 kHz Edgetech Side Scan Sonars • Imagenex Delta-T 265 kHz Multibeam Imaging Sonar • Omni Sub-bottom Profiling Sonar • Hydroid Electronic Still Camera (2048x2048) with strobe • Sea-Bird CTD • Fluorometer

5. Configuration flexibility on deck)

8. Two Parallel Survey Rows • Centered on running baseline • Allows for continuous ladder progression up rows regardless of truncated missions • - Maximize transponder deployments • Overlapping mission to mission track lines • Usual ship movements on baseline axis • Effective Re-Acquire Protocol
