Multi-Autonomous Underwater Vehicle Full-Coverage Path-Planning Algorithm Based on Intuitive Fuzzy Decision-Making

Journal of Marine Science and Engineering
Aiming at the difficulty of realizing full-coverage path planning in a multi-AUV collaborative search, a multi-AUV full-coverage path-planning algorithm based on intuitionistic fuzzy decision-making is proposed. First, the state space model of the search

Virtual Elastic Tether: A New Approach for Multi‐Agent Navigation in Confined Aquatic Environments

Journal of Field Robotics, Volume 43, Issue 5, Page 3332-3350, August 2026.
ABSTRACT Underwater navigation is a challenging area in the field of mobile robotics due to inherent constraints in self‐localization and communication in underwater environments. Some of these challenges can be mitigated by using collaborative multi‐agent teams.

Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract For the first time, the Autosub Long Range (ALR) completed a fully autonomous, long‐distance (2,000 km) scientific mission, delivering new insight into coastal carbonate dynamics and air‐sea CO2 ${\text{CO}}_{2}$ fluxes. Equipped with a suite of oceanographic sensors, including a Lab‐on‐Chip (LOC) pH sensor and a Sea‐Bird SeaFET pH sensor, the

Seafloor Displacements Across the Mid‐Ocean Ridge Eruption Cycle Modulated by Mush Zone Viscosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Mid‐ocean ridges (MORs) are active volcanic systems where axial magma lenses (AMLs) are replenished on decadal time scales, enabling frequent dike intrusions. The associated seafloor deformation, however, remains scarcely understood. Here we assess this deformation by simulating cycles of steady AML inflation followed by instantaneous dike ...

Modeling of Autonomous Underwater Vehicles with Multi-Propellers Based on Maximum Likelihood Method

Journal of Marine Science and Engineering, 2020
The hydrodynamic characteristics of multi-propeller autonomous underwater vehicles (AUV) is usually complicated and it is difficult to obtain an accurate mathematical model. A modeling method based on CFD calculation and maximum likelihood identification

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

Journal of Fish Biology, Volume 109, Issue 2, Page 693-714, August 2026.
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.

Tectonic Controls on Volcanism and Associated Hydrothermal Activity in a Sediment‐Dominated Mid‐Ocean Ridge; Escanaba Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Mid‐ocean ridges, the Earth's most extensive volcanic system, exhibit unique characteristics in sediment‐dominant environments. Thick sediment cover insulates the crust and channels fluid along pathways that can lead to the formation of distinct crustal alteration patterns, exceptionally large mineral deposits, and specialized chemosynthetic ...

A Novel Cooperative Navigation Algorithm Based on Factor Graph and Lie Group for AUVs

Journal of Marine Science and Engineering
Traditional cooperative navigation algorithms for multiple AUVs are typically designed for a single specific configuration, such as parallel or leader-slave. This paper proposes a novel cooperative navigation algorithm based on factor graph and Lie group
