Acoustic-Triggered
Marine Surveillance Module
Solving the blind spot in ropeless fishing to protect whale migration corridors.
The Whale Migration Crisis
Commercial crab fishing faces a massive existential threat: Whale entanglements. Traditional traps use vertical ropes connecting the seafloor cage to a surface buoy. When whales migrate, they can become lethally entangled in these lines.
This forces entire fisheries to close for months during migration seasons, costing millions. The industry needs a way to fish without vertical ropes.
SubSea Sonics & The Acoustic Trigger
Ropeless fishing. The buoy stays locked to the trap on the seafloor. When the fisherman returns, they blast a specific acoustic signal into the water. The buoy "hears" it, unlocks, and floats to the surface for retrieval.
The Problem: It's a black box. SubSea Sonics needed to know exactly how their release mechanism performed in the unpredictable, muddy, high-current conditions of the real ocean floor. They were flying blind.
The Acoustic Camera Module
I engineered a custom surveillance package designed to attach to the crab trap and autonomously record the release event.
Acoustic Wake-Up
To save battery during week-long deployments, the Pi stays in deep sleep. A low-power analog circuit listens for the specific "Release" ping and wakes the system instantly.
Pressure Housing
Custom machined acrylic housing rated for 150m depth, ensuring the electronics survive the crushing pressure of the crab grounds.
