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

Anterior Urethral Valve and Anterior Urethral Diverticulum with an Intradiverticular Stone: A Case Report and a Literature Review

Journal of Urological Surgery, 2018
Anterior urethral valve (AUV) is a rare but well-defined congenital anomaly. AUV can be isolated or occur in association with anterior urethral diverticulum (AUD).

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 ...

Multi-AUV Cooperative Target Hunting Based on Improved Potential Field in a Surface-Water Environment

Applied Sciences, 2018
In this paper, target hunting aims to detect target and surround the detected target in a surface-water using Multiple Autonomous Underwater Vehicles (multi-AUV) in a given area. The main challenge in multi-AUV target hunting is the design of AUV’s

Wake-Responsive AUV Guidance Assisted by Passive Sonar Measurements

Journal of Marine Science and Engineering
To make an Autonomous Underwater Vehicle (AUV) chase a moving target ship that generates wake, wake-responsive guidance can be used. This scenario is applicable to making an underwater torpedo pursue a moving target ship until hitting the target.

Decentralized deployment with obstacle avoidance for AUVs*

IFAC Proceedings Volumes, 2011
Abstract In multiple robotic system, the deployment problem consists in the optimal placement of the robots within a given environment. In this paper, a fully decentralized strategy, based on the so called Null-Space-based Behavioral control is proposed.
