• 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

• 120/410 kHz and 230/540 kHz Edgetech Side Scan Sonars

• Imagenex Delta-T 265 kHz Multibeam Imaging Sonar

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

Mission Profile

- Weighted Descent: 2hr 15 min

- Survey Time: 18 hr 30 min (122Km)
