A comparison of recreational and survey‐grade side‐scan sonar systems in mapping reservoir fish habitat

North American Journal of Fisheries Management
Littoral zone aquatic habitat is an important component of sport fish population dynamics in freshwater lakes and reservoirs and is a primary target of fisheries management actions. However, habitat data for these systems are often minimal or nonexistent

Optimizing AUV Navigation Using Factor Graphs with Side-Scan Sonar Integration

Journal of Marine Science and Engineering
For seabed mapping, the prevalence of autonomous underwater vehicles (AUVs) employing side-scan sonar (SSS) necessitates robust navigation solutions. However, the positioning errors of traditional strapdown inertial navigation system (SINS) and Doppler ...
