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

open access: yesJournal 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.

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

open access: yesEarth 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

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

open access: yes, 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 ...

Holocene subaqueous landslide dynamics in the Lake Siljan‐Orsasjön Basin, south‐central Sweden

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Subaqueous landslide areas studied by multibeam bathymetry, sub‐bottom profiling and sediment coring reveal complex stratigraphies, suggesting mass movement events starting close to the area's deglaciation and up to very recent times. Abstract The Siljan‐Orsasjön Basin in south‐central Sweden hosts two prominent lakes.

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search

open access: yesJournal of Field Robotics, Volume 43, Issue 2, Page 561-577, March 2026.
ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

A Mass Conservation Model to Study the Evolution of Coastal Soft Cliffs Driven by Sea Level Rise Over Multi‐Century Timescales

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Soft cliffed coasts are particularly vulnerable to erosion and their retreat depends on environmental, geological and geomechanical factors. In this work, we use a mathematical modeling approach to understand effects of future global sea level rise on these coasts over multiple centuries.

Influence of Biofilms and Extracellular Polymeric Substances on High‐Frequency Acoustic Backscatter

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Acoustic Backscatter Technique has been used to detect underwater targets and characterize seabed and river floor sediment properties. Microbial biofilms, consisting of microorganisms enclosed in Extracellular Polymeric Substances (EPS), have the potential to modify acoustic backscatter by altering the sediment topography, permeability, and ...

Autonomous Underwater Vehicle untuk Survei dan Pemantauan Laut

open access: yesJurnal 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.
