Sliders and Gliders: Autonomous Underwater Gliders

 

Sliders and Gliders: Autonomous Underwater Gliders

There is no better way to get up to speed on an unfamiliar topic than to read a well written, well documented review article on the subject.

If sub gliders fit into the category of unfamiliar topics for you, have I got a great article for you …

Autonomous Underwater Glider: A Comprehensive Review

So, what is a “sub glider?” According to the introductory paragraph from Autonomous Underwater Glider

A sub glider (SG or sub glider), also known as an Autonomous Underwater Glider (AUG), is a vehicle designed to glide through the water in a manner like the flight of a bird: for many years now, vehicles like these have been used for various oceanographic research and environmental monitoring applications, as well as for commercial purposes such as offshore oil and gas exploration.

The article goes on to describe the history of sub gliders (SGs) and to project future developments and uses of the technology.
