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 ...

Real‐Time Detection and Prevention of DoS Attack in Unmanned Marine Vehicles Using Machine Learning

SECURITY AND PRIVACY, Volume 9, Issue 2, March/April 2026.
ABSTRACT Unmanned marine vehicles (UMVs) are one of the most crucial components of the underwater communication and surveillance system in the marine and oceanographic environment. This research introduces a novel approach to stabilize the connection in an unstable underwater environment by inheriting features of communication velocities.

Are Contrived Lecture Passages From International Academic English Assessments Lexically Comparable to Actual University Lectures?

TESOL Journal, Volume 17, Issue 1, March 2026.
ABSTRACT The vocabulary load of university lectures and the coverage of academic vocabulary in spoken discourse have been used as benchmarks in researching whether various listening sources lexically correspond to actual university lectures. However, it remains unexplored whether contrived lecture passages from international academic English ...

Intense Isopycnal Stirring and Double‐Diffusion Contributing to Microscale Variance in the Kuroshio Extension Front

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract In oceanic frontal regions, isopycnal stirring induces lateral thermohaline intrusion. Previous studies have observed interleaving layers in the Izu Ridge and Kuroshio Extension attributed to isopycnal stirring driven by mesoscale eddies and submesoscale flows.

An Adaptive Prediction Target Search Algorithm for Multi-AUVs in an Unknown 3D Environment

Sensors, 2018
For a target search of autonomous underwater vehicles (AUVs) in a completely unknown three-dimensional (3D) underwater environment, a multi-AUV collaborative target search algorithm based on adaptive prediction is proposed in this paper.

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

Biodiversity research requires more motors in air, water and on land

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 668-682, March 2026.
Abstract Human activities have accelerated species extinctions, driving rapid biodiversity decline. Simultaneously, advancements in Artificial Intelligence (AI) and autonomous systems offer transformative potential for biodiversity research. Uncrewed vehicles—drones (aerial systems) and other robots (ground and underwater platforms)—equipped with high ...

Characteristic Geometry of Keels in Arctic Sea Ice Ridges

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Deformation within and between sea ice floes creates pressure ridges, which compose a considerable volume fraction of the Arctic sea ice cover and complicate sea ice volume measurements. An important parameter for quantifying the ice volume contained in these deformation features is the keel shape.
