Experimental Verification of Underwater Glider Maneuvering in Constrained Environments
IEEE/OES Autonomous Underwater Vehicles, 2022This paper presents experimental ground truth data validation of the ability of Underwater Gliders (UGs) to maneuver in constrained environments through starting, stopping, and maintaining turning motions on demand.

Underwater Gliders for Ocean Research
Marine Technology Society Journal, 2004Underwater gliders are autonomous vehicles that profile vertically by controlling buoyancy and move horizontally on wings. Gliders are reviewed, from their conception by Henry Stommel as an extension of autonomous profiling floats, through their development in three models, and including their first deployments singly and in numbers.

Gliding in extreme waters: Dynamic Modeling and Nonlinear Control of an Agile Underwater Glider
IFAC-PapersOnLineThis paper describes the modeling of a custom-made underwater glider capable of flexible maneuvers in constrained areas and proposes a control system. Due to the lack of external actuators, underwater gliders can be greatly influenced by environmental ...

The autonomous underwater glider "Spray"
IEEE Journal of Oceanic Engineering, 2001A small (50-kg, 2-m long) underwater vehicle with operating speeds of 20-30 cm/s and ranges up to 6000 km has been developed and field tested. The vehicle is essentially an autonomous profiling float that uses a buoyancy engine to cycle vertically and wings to glide horizontally while moving up and down.

Lagrangian Modelling of an Underwater Wave Glider
Ship Technology Research, 2012AbstractThis paper introduces a control-oriented modelling approach for a hybrid autonomous underwater vehicle, the Underwater Wave Glider. The vehicle can accomplish both surface and underwater tasks by changing its shape: it can operate as a wave glider at the sea surface, exploiting wave and solar energy to recharge the onboard batteries, and switch

Sampling optimization for networked underwater gliders
OCEANS 2016 - Shanghai, 2016This paper focuses on coverage sampling over a given region by a fleet of underwater gliders. The coverage performance is evaluated by the observing uncertainty performed by Objective Analysis (OA). Deployed gliders are commonly restricted to move through transects along which the data collected are convenient for data assimilation.

OCEANOGRAPHIC ENVIRONMENTAL ASSESSMENT USING UNDERWATER GLIDERS
Journal of Marine Technology and Environment, 2022REP(MUS) 21 is an annual exercise jointly organised by the Portuguese Navy, the University of Porto, NATO’s Centre for Maritime Research and Experimentation (CMRE) and the NATO Maritime Unmanned Systems Initiative. The exercise gives Allies and NATO partners a chance to field and evaluate new maritime technologies.

Ocean Research Enabled by Underwater Gliders
Annual Review of Marine Science, 2016Underwater gliders are autonomous underwater vehicles that profile vertically by changing their buoyancy and use wings to move horizontally. Gliders are useful for sustained observation at relatively fine horizontal scales, especially to connect the coastal and open ocean. In this review, research topics are grouped by time and length scales.
