ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Mini-sonar---A Miniaturized Sector Scanning Sonar [PDF]
Use of small submersibles has increased in recent years. A vehicle that is simply a swimming TV camera can be made quite small, but its utility is limited because of its limited view of its surroundings. The mini-sonar program was started at NOSC to develop a small sector scanning sonar for use on small vehicles without affecting their bulk.

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

The use of active sonar to study cetaceans
Cetacean species face serious challenges worldwide due to the increasing noise pollution brought to their environment by human activities such as seismic exploration. Regulation of these activities is vaguely defined and uncoordinated.
