MARS: Programmable multipurpose auto‐release system for aquatic observations
Limnology and Oceanography: Methods, Volume 23, Issue 6, Page 376-388, June 2025.Abstract Aquatic biodiversity assessments are often labor‐intensive due to the large size of the equipment and the complex logistics of sea vessel operations. Traditional drift and drop cameras are typically tethered to the surface, causing cable and line clutter on sea vessels.

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.A dual‐layer formation control with a predefined‐time and collision‐free strategy is studied in this work. Its upper layer utilises performance indicators, including tracking objectives to meet tracking control requirements. The lower layer tracks those trajectories to save computational and communication resources.

PBM‐YOLO: A Performance Balanced Floating Garbage Detection Model for Water Surface Environments
IET Image Processing, Volume 19, Issue 1, January/December 2025.We propose a lightweight detection model, PBM‐YOLO, for floating garbage detection on water surfaces. Based on YOLOv8n, the model introduces a feature extraction module (FSEM) that integrates frequency and spatial information to enhance object representation.
