An Adaptive Image-stitching Algorithm for an Underwater Monitoring System
Against the narrow range of sonar images for underwater monitoring, an adaptive sonar image-stitching algorithm is proposed in this paper. Compared with conventional sonar image-stitching algorithms, this algorithm can be applied to stitch sonar images ...

ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

Research and analysis on military strength demand of dipping sonar on-call submarine searching based on submarine evasion [PDF]
Based on the actual process of dipping sonar in on-call submarine searching, combined with the classic extended spiral search method, a multi machine dipping sonar on-call submarine searching model was established.

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.

Sonar behaviour in non-terrestrial ocean exploration [PDF]
A goal for a future Europan payload is to determine the extent of the postulated sea, aspects of acoustic remote sensing are discussed with a view to operating a sonar in such an subsurface ...

Evaluation and Verification of Bottom Acoustic Reverberation Statistics Predicted by the Point Scattering Model [PDF]
The point scatteringmodel offers a parameterization of the reverberation probability density function (pdf) in terms of the coefficient of excess (kurtosis) and a coherent component represented by a harmonic process with random phase.
