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

Journal 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

Journal 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

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.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

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.

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

Advanced Robotics Research, Volume 2, Issue 1, February 2026.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

A 16‐Year Green Sturgeon Population Survey: Investigating River Discharge, Species Identification, Sampling Technology, Survey Extent and Possible Spawning Cyclic Dominance

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Monitoring and understanding the population structure of anadromous fishes is vital to their conservation. The southern distinct population segment of green sturgeon (Acipenser medirostris) is a threatened long‐lived anadromous fish, for which we have insufficient information about fundamental aspects of population structure.

Applicability of Traditional Acoustic Technology for Underwater Archeology: A Case Study of Model Detection in Xiamen Bay

Acoustics
This study addresses the applicability of conventional marine acoustic technologies for detecting non-metal artifacts. Based on the typical environment in Xiamen Bay, we evaluated the detection efficacy of common multibeam sonar, side-scan sonar, and sub-

Grounds, Beds, and Reefs of the Endangered Coral Cladocora caespitosa With Description of the Tremiti Reef

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study provides an overview of the distribution of the three ecosystem types formed by Cladocora caespitosa and describes newly discovered ones at Tremiti Islands (Adriatic Sea, Italy). The spatial distribution, biometry, size structure, and conservation status of the Cladocora formations have been investigated and compared at the Mediterranean ...
