Side-Scan Sonar Applications for Evaluating Coastal Structures [PDF]
Applications of side-scan sonar for inspecting coastal structures were evaluated. Results were based on 6 years of structure inspections, including structures on the Atlantic, Pacific, Gulf, and Great Lakes coasts of the United States. Most of the structures inspected were jetties and breakwaters; however, applications for vertical wall structures and ...

Side-Scan Sonar Image Generation Under Zero and Few Samples for Underwater Target Detection
The acquisition of side-scan sonar (SSS) images is complex, expensive, and time-consuming, making it difficult and sometimes impossible to obtain rich image data.

Sub‐annual spatiotemporal dynamics of sediment and organic matter storage in beaver ponds
Ponds higher up the beaver cascades showed increasing erosion of sediments following heavier rainfall events, whereas those further down showed increasing sediment accretion. Following periods with less intense rainfall all ponds showed net sediment accretion.

Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

ABSTRACT This study presents a novel remote sensing method to detect 17th‐century environmental elements associated with the historical fortifications of Gdanska Glowa in Poland. By integrating 10‐band multispectral imaging, high‐resolution (1 m) digital elevation models, vegetation metrics and random forest classification within Google Earth Engine ...

Side‐scan sonar (SSS) is a powerful tool that can be used to address many key questions in fisheries science. In principle, SSS uses dual transducers to transmit a narrow‐beam, wide‐angle acoustic signal as the survey vessel transits an area.

Autonomous Underwater Vehicle untuk Survei dan Pemantauan Laut
AUV is an unmanned submersible platform to accomplish a mission. Side-scan sonar, Conductivity Temperature Depth (CTD), and underwater video camera are usually attached on AUV. These sensors were used for identifying seawater and seabed condition.
