Randomized trial demonstrates effective acoustic sensing in ultra-shallow water, suggesting a new solution for challenging environments.

This research aims to develop and validate a portable side-scan sonar system for surveying ultra-shallow seafloor environments.
Built a battery-powered acoustic survey system with a dual-frequency side-scan sonar and RTK GNSS.
Conducted field trials in an inland lake and a marina for system validation.
Assessed the image quality and detection capabilities of the sonar system.
High-resolution sonar imagery was reliably acquired in both testing environments.
The 1600 kHz frequency channel provided superior image quality compared to 600 kHz.
Effective detection of natural and anthropogenic seabed features, including low-reflectivity objects.

Grządziel et al. (2026) studied this question.
