Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Deep blueprint: A literature review and guide to automated image classification for ecologists

Journal of Animal Ecology, EarlyView.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Thruster fault diagnosis method based on Gaussian particle filter for autonomous underwater vehicles

International Journal of Naval Architecture and Ocean Engineering, 2016
Autonomous Underwater Vehicles (AUVs) generally work in complex marine environments. Any fault in AUVs may cause significant losses. Thus, system reliability and automatic fault diagnosis are important.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Boundary Control Behaviors of Multiple Low-Cost AUVs Using Acoustic Communication

IEEE Access
This study presents acoustic-based methods for the formation control of multiple autonomous underwater vehicles (AUVs). This study proposes two different models for implementing boundary and path control on low-cost AUVs using acoustic communication and ...

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...

A Low-cost Electromagnetic Docking Guidance System for Micro Autonomous Underwater Vehicles

Sensors, 2019
As important observational platforms for the Smart Ocean concept, autonomous underwater vehicles (AUVs) that perform long-term observation in fleets are beneficial because they provide large-scale sampling data with a sufficient spatiotemporal resolution.

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...

AUV with Variable Vector Propeller

Journal of Robotics and Mechatronics, 2000
We developed an autonomous underwater vehicle (AUV) with a distributed controller and underwater acoustic communication. It is compact and lightweight thanks to its variable vector propeller and control using sophisticated logic circuits. Control is very precise using underwater ultrasonic command signals.
