TL;DR: Underwater gliders are autonomous vehicles that profile vertically by buoyancy control and move horizontally on wings as mentioned in this paper, and are among the best approaches to achieving subsurface spatial resolution necessary for ocean research.
Abstract: Underwater gliders are autonomous vehicles that profile vertically by buoyancy control and move horizontally on wings. Gliders are reviewed, from their conception by Stommel as an extension of autonomous profiling floats, through their development in 3 models, and including their first deployments singly and in numbers. This paper discusses the basics of glider function as implemented by University of Washington, Seaglider, Scripps Institution of Oceanography, and Webb Research in Slocum. Preliminary results are presented from a recent demonstration project that used a network of gliders off Monterey. A wide range of sensors has already been deployed on gliders, with many under development, and a wider range of future possibilities. Glider networks appear to be among the best approaches to achieving subsurface spatial resolution necessary for ocean research.

TL;DR: The design of an autonomous underwater vehicle and a simulation system for AUVs as part of the initiative for establishing a new international competition for autonomous underwater vehicles, both physical and simulated.
Abstract: We present the design of an autonomous underwater vehicle and a simulation system for AUVs as part of the initiative for establishing a new international competition for autonomous underwater vehicles, both physical and simulated. This paper describes the competition outline with sample tasks, as well as the construction of the AUV and the simulation platform.

TL;DR: The ORCA-VII is a fully autonomous submarine built to compete in the 2004 International AUV competition and aided by a suite of instruments including a water pressure depth sensor, a fluid-bulb inclinometer, a DSP based sonar direction finder, a magnetic compass, an inertial measurement unit, and an underwater video camera with computer vision software.
Abstract: The ORCA-VII is a fully autonomous submarine built to compete in the 2004 International AUV competition. The ORCA-VII is 48" long, 28" wide, and approximately 45 kg. The vehicle is propelled by a pair of horizontal thrusters mounted on the sides and a pair of vertical thrusters on the bow and stern. Autonomous navigation is aided by a suite of instruments including a water pressure depth sensor, a fluid-bulb inclinometer, a DSP based sonar direction finder, a magnetic compass, an inertial measurement unit, a light source tracker and an underwater video camera with computer vision software.
