Surface warming-induced global acceleration of upper ocean currents. [PDF]

Sci Adv, 2022
How the ocean circulation changes in a warming climate is an important but poorly understood problem. Using a global ocean model, we decompose the problem into distinct responses to changes in sea surface temperature, salinity, and wind. Our results show

A Novel Unmanned Surface Vehicle Path-Planning Algorithm Based on A* and Artificial Potential Field in Ocean Currents

Journal of Marine Science and Engineering
Ocean currents make it difficult for unmanned surface vehicles (USVs) to keep a safe distance from obstacles. Effective path planning should adequately consider the effect of ocean currents on USVs.

Nutrient-supplying ocean currents modulate coral bleaching susceptibility. [PDF]

Sci Adv, 2020
Nutrients become a death knell 5 for corals as the ocean warms. With predictions that mass coral bleaching will occur annually within this century, conservation efforts must focus their limited resources based on an accurate understanding of the drivers ...

Monitoring ocean currents during the passage of Typhoon Muifa using optical-fiber distributed acoustic sensing. [PDF]

Nat Commun
In situ observations under typhoon conditions are sparse and limited. Distributed acoustic sensing (DAS) is an emerging technology that uses submarine optical-fiber (OF) cables to monitor the sea state.

Ocean currents promote rare species diversity in protists. [PDF]

Sci Adv, 2020
Transport by ocean currents contributes to the diversity of planktonic species observed in metagenomic studies. Oceans host communities of plankton composed of relatively few abundant species and many rare species.

Bio-Inspired Neural Network-Based Optimal Path Planning for UUVs Under the Effect of Ocean Currents [PDF]

IEEE Transactions on Intelligent Vehicles, 2021
To eliminate the effect of ocean currents when addressing the optimal path in the underwater environment, an intelligent algorithm designed for the unmanned underwater vehicle (UUV) is proposed in this paper. The algorithm consists of two parts: a neural

Anisotropic GPMP2: A Fast Continuous-Time Gaussian Processes Based Motion Planner for Unmanned Surface Vehicles in Environments With Ocean Currents

IEEE Transactions on Automation Science and Engineering, 2022
In the past decade, there is an increasing interest in the deployment of unmanned surface vehicles (USVs) for undertaking ocean missions in dynamic, complex maritime environments. The success of these missions largely relies on motion planning algorithms

Thruster Fault Diagnostics and Fault Tolerant Control for Autonomous Underwater Vehicle with Ocean Currents

Machines, 2022
Autonomous underwater vehicle (AUV) is one of the most important exploration tools in the ocean underwater environment, whose movement is realized by the underwater thrusters, however, the thruster fault happens frequently in engineering practice.

Improved RRT algorithms to solve path planning of multi-glider in time-varying ocean currents

IEEE Access, 2021
In this paper, through the application research of underwater gliders, it is found that ocean currents are the major influencing factor in the practical application of gliders. The objective of this study is to solve the path planning of glider formation
