Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning

Journal of Field Robotics, Volume 43, Issue 6, Page 3617-3632, September 2026.
ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.

Study on path planning of unmanned surface vessel based on data-driven genetic algorithm

智能科学与技术学报, 2019
The genetic algorithm (GA) is an effective method for the path planning system of unmanned surface vessel (USV),but it is easy to fall into local optimal precocity and converges slowly.For this,without increasing the complexity of the algorithm,a data ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management

Fish and Fisheries, Volume 27, Issue 5, Page 1134-1150, September 2026.
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.

The Türkiye‐Qatar Partnership: From Ottoman Roots to Strategic Alliance

Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.
Abstract As Qatar, a small country in a strategic location, faced a pressure campaign from Gulf states in 2017, Türkiye expanded its military presence and provided support that proved crucial to Doha's ability to overcome the crisis. This demonstrated Türkiye's new grand strategy, its capacity to project influence into the Gulf, and its status as a ...

Enhancing Intra‐Specific Population Genetic Studies of Bottlenose Dolphins (Tursiops truncatus) in Irish Waters by Integrating Least Invasive Sampling and Environmental DNA (eDNA)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Three populations of bottlenose dolphins are found in Irish waters. This study used direct sampling methods to expand the sample size and confirm the distinctiveness of these populations, including a range expansion outside of the Shannon Estuary SAC.
