Australian National Facility for Ocean Gliders (ANFOG)
The Ocean Gliders facility operates a fleet of autonomous underwater ocean gliders that undertake measurements from shelf and boundary currents in Australian waters. As traditional ship-based oceanographic observations are expensive and time consuming, the development of autonomous ocean gliders to sample the marine environment represents a technological revolution for oceanography. The gliders are relatively cheap, reusable and can be remotely controlled, making them a relatively cost-effective method for collecting repeat subsurface ocean observations. They also allow for the acquisition of data under inclement weather conditions. Equipped with a variety of sensors, the gliders are designed to deliver ocean profile data. Furthermore, the unique design of the gliders enables them to move horizontally through the water while collecting vertical profiles. The use of these contemporary gliders provides a unique opportunity to effectively measure the boundary currents off Australia, which are the main link between open-ocean and coastal processes. The Ocean Gliders facility operates a number of gliders with target regions including the Coral Sea, East Australian Current off New South Wales and Tasmania, Southern Ocean southwest of Tasmania and the Leeuwin and Capes Currents off Western Australia.
