Optimal design of combined propulsion Underwater Glider for operation of the East Sea of South Korea

Advances in Mechanical Engineering, 2019
An underwater glider is an autonomous underwater vehicle that is propelled by changes in volume. Due to this propulsion method, it is possible to make observations with these devices continuously for 30–60 days.

A Study of the Three-Dimensional Localization of an Underwater Glider Hull Using a Hierarchical Convolutional Neural Network Vision Encoder and a Variable Mixture-of-Experts Transformer

Remote Sensing
Although underwater gliders are highly energy-efficient platforms capable of long-duration and large-scale ocean observation, their lack of self-propulsion requires external assistance for recovery upon mission completion.

Motion Parameter Optimization and Sensor Scheduling for the Sea-Wing Underwater Glider

, 2013
Underwater gliders adjust buoyancy to generate gliding motion through water columns using a pair of wings. Various types of underwater gliders have been developed and have been tested as efficient long-distance, long-duration ocean sampling platforms. We
