While WHOI’s more familiar autonomous underwater vehicle (AUV) Sentry is exploring the seafloor for hydrothermal vents at depth, it will relay data back acoustically via the Wave Glider. Why does the Wave Glider interest you? The Wave Glider is critical to that as a gateway. How does the Wave Glider work with existing underwater vehicles and what problems does it help solve? If Sentry finds anything interesting in its sensor data—if it “sniffs” a new vent—it will be able to alert me via the Wave Glider immediately.
