PING‐Mapper: Open‐Source Software for Automated Benthic Imaging and Mapping Using Recreation‐Grade Sonar

Earth and Space Science, 2022
The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation‐grade side‐scan sonar systems are increasingly used to aid scientific inquiries in

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Bilinear Pooling With Poisoning Detection Module for Automatic Side Scan Sonar Data Analysis

IEEE Access, 2023
Side-scan sonar (SSS) images are difficult for automatic analysis due to the acoustic measurement parameters as well as the number of different objects that can be distant. In addition, there is a risk that the seabed analysis application may be attacked.

Side-Scan Sonar Applications for Evaluating Coastal Structures [PDF]

, 1988
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 ...

Effects of Wintertime Snow Depth Assimilation on Summertime Sea Ice Prediction Experiments Utilizing a Fully Coupled Regional Arctic Model With Perfect Boundary Conditions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract During the past decades, the rapid decline of sea ice in the Arctic Ocean has substantially favored commercial navigation activities in the summertime. Numerical sea ice prediction on a seasonal scale plays a crucial role in guiding the programme of such activities, yet the role of snow depth data assimilation in numerical sea ice prediction ...

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Thermoelectric Properties of a Diketopyrrolopyrrole Polymer With Radical Pending Units

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
The successful incorporation of TEMPO radicals as side‐chain groups onto the conjugated backbone of an n‐type polymer significantly enhanced the doping efficiency of N‐DMBI via a hydrogen transfer doping mechanism. ABSTRACT Organic n‐type polymers usually suffer from relatively low electrical conductivity which hampers their application as an active ...

Sea Bottom Line Tracking in Side-Scan Sonar Images Using WTMM-Based Edge Detection

Journal of Marine Science and Engineering
The topographic features of the seafloor can be observed clearly via high-resolution side-scan sonar imagery. However, the faithful interpretation of a sonar image depends strongly on the accuracy with which the location of the sea bottom line can be ...

Autonomous Underwater Vehicle untuk Survei dan Pemantauan Laut

Jurnal Rekayasa Elektrika, 2017
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.
