Ocean gliders are versatile tools for making ocean observations. This paper summarizes the experience, of nearly two decades, glider observing activity in Atlantic Canada. It reviews key considerations operating based on experience and lessons learned. has three main goals: 1. To provide new emerging users with guidance developing a program. 2. Review literature sensor development use gliders. ...

Marine Autonomous Systems (MAS) operating at sea beyond visual line of sight need to be self-reliant, as any malfunction could lead loss or pose a risk other users. In the absence fully automated on-board control and fault detection tools, MAS are piloted monitored by experts, resulting in high operational costs limiting scale observational fleets that can deployed simultaneously. Hence, an eff...

The long-term goal of this research is to enable a cooperating group of underwater gliders to perform efficiently and robustly as an autonomous, adaptive sampling network in a three-dimensional, dynamic ocean environment. This will involve developing the mathematical infrastructure and design tools for effecting feedback-controlled, schooling-like network behavior in an unsteady flow field whil...

(ABSTRACT) Underwater gliders are highly efficient, winged autonomous underwater vehicles that propel themselves by modifying their buoyancy and their center of mass. The center of mass is controlled by a set of servo-actuators which move one or more internal masses relative to the vehicle's frame. Underwater gliders are so efficient because they spend most of their time in stable, steady motio...

In order to take measurements in space and time from the undersampled vast ocean, it is necessary to employ multiple autonomous underwater vehicles, such as gliders, that communicate and coordinate with each other. These vehicles need to form a team in a specific formation, steer through the 3D region of interest, and take application-dependent measurements such as temperature and salinity. In ...

Underwater gliders are type of autonomous underwater vehicle that glide by controlling their buoyancy and attitude using internal actuators. By changing the vehicle’s buoyancy intermittently, vertical motion can be achieved. Characteristic of glider motions include upward and downward in a saw tooth pattern, turning and gliding in a vertical spiral motion glides without using thrusters or prope...

Underwater gliders have proven to be a powerful tool in oceanography because they are reusable, inexpensive and achieve a high duration. These qualities have made the acquisition of oceanographic data sets more accessible. The purpose of this article is to present a study aimed at modelling an underwater glider in the longitudinal and lateral plane. The proposed glider possesses a single stroke...
