A Mapping Method Fusing Forward-Looking Sonar and Side-Scan Sonar

Journal of Marine Science and Engineering
In modern ocean exploration, forward-looking sonar (FLS) provides real-time 2D imaging of the seabed ahead, but its detection range is relatively limited.

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

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

Radical‐Mediated Dispersion Breaks Aggregation Limits in Carbon Thermoelectrics

Angewandte Chemie International Edition, Volume 65, Issue 35, 24 August 2026.
We report a rationally designed small molecule (OTN) that effectively disperses SWCNTs via π–π and radical‐radical interactions, yielding hybrid films with a record power factor of 30.1 µW cm−1 K−2 and excellent flexibility. A nine‐leg device achieves a record normalized power density of 0.653 µW cm−2 K−2, setting a new benchmark for carbon‐based ...

Point‐Of‐Care Ultrasound Pronator Quadratus Haematoma Sign Visualised in Adult Distal Radius Fractures: A Case Series

Australasian Journal of Ultrasound in Medicine, Volume 29, Issue 3, August 2026.
ABSTRACT Background Subtle fractures of the distal forearm in adults are not always readily apparent on radiography. Point‐of‐care ultrasound (POCUS) offers a potentially valuable adjunct to conventional radiography in fracture diagnosis. The main advantage of POCUS over radiography is its ability to delineate soft tissue structures, which can provide ...

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.

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Inversion of Side Scan Sonar Motion and Posture in Seabed Geomorphology

Polish Maritime Research, 2017
Side scan sonar measurement platform, affected by underwater environment and its own motion precision, inevitably has posture and motion disturbance, which greatly affects accuracy of geomorphic image formation.

Robust Regional Contrast but Penetration‐Sensitive Snow Thickness Over Sea Ice From Multi‐Winter Antarctic CRYO2ICE Observations

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Snow on Antarctic sea ice modulates albedo, thermodynamic growth, and snow–ice formation, yet remains a leading uncertainty in altimetry‐derived sea‐ice thickness. Here we use the post‐2022 CRYO2ICE configuration to derive along‐track winter snow thickness from ICESat‐2 laser and CryoSat‐2 Ku‐band radar freeboards over the Weddell and Ross ...
