Glider Technology for Ocean Observations: A Review

Abstract. The total number of drones used in the air, on the land and in the water is growing in recent years. This review focuses on ocean robots and in particular on glider technology which seems to be one of the most promising oceanographic tools for future marine research.

Glider are remotely controlled underwater vehicles carrying out missions with lifetime exceeding months, traveling thoundsands of kilometers, even through harsh environments. Depending on their scientific payload, they can be used for very specific research tasks, as well as for common environmental monitoring purposes. In combination with other technologies (e.g. moorings, satellites, drifters, floats) and as a part of existing observation networks they are of great advantage and thus help to get a more synoptic view on the world's oceans.

This review covers a wide range of topics – from the history and the development of glider technology to its application in a variety of field studies regarding marine sciences. It offers a comprehensive overview of both, the technical and the scientific dimension, facilitating a fast access to the world of glider.
