underwater glider

Underwater gliders do not directly propel themselves.

The CSIRO used a robotic underwater glider to make sub-surface measurements.

The concept of an underwater glider was first explored in the early 1960s with a prototype swimmer delivery vehicle named Concept Whisper.

In particular, the COOL group has helped to develop and test high-frequency radar and underwater glider technologies.

EGO (underwater gliders)

Underwater gliders convert buoyancy to thrust, using wings, or more recently hull shape (SeaExplorer Glider).

In late November 2005, the DDS was used to launch an underwater glider capable of gathering and storing information to be later transmitted by means of a built-in satellite phone.

Most of those data are real-time data coming from different types of platforms (research vessels, profilers, underwater gliders, drifting buoys, moored buoys, sea mammals, opportunity ships,...).

Liberdade class flying wings are autonomous underwater gliders developed by the US Navy Office of Naval Research which use a blended wing body hullform to achieve hydrodynamic efficiency.

Also, ultra-low-power, long-range variants such as underwater gliders are becoming capable of operating unattended for weeks or months in littoral and open ocean areas, periodically relaying data by satellite to shore, before returning to be picked up.

An underwater glider is a type of autonomous underwater vehicle (AUV) that uses small changes in its buoyancy in conjunction with wings to convert vertical motion to horizontal, and thereby propel itself forward with very low power consumption.

Members of the Liberdade class are the world's largest known underwater gliders and were developed as part of the US Navy's Persistent Littoral Undersea Surveillance Network (PlusNet) system of unmanned surveillance vehicles.

AMIND as supple and creative as Prof. Naomi Ehrich Leonard's, one that allows her to chart the patterns of schools of fish and then construct underwater gliders that mimic their movement, would seem to be at odds with her surroundings.
