"Southern Ocean Mobile Assets include two types of gliders that sample the area around the triangular mooring array. An array of 3 Open Ocean Gliders (GLnnn) survey within/between moorings, while two Global Profiling Gliders (PGnnn) survey the upper water column above the Southern Ocean Apex Profiler Mooring. Gliders are buoyancy-driven mobile assets that travel along saw-toothed transects, penetrating the sea surface and diving down to a maximum depth of 1,000 meters. They change their buoyancy by drawing in water through their nose making their front end heavy causing them to sink through the water. To float back up to the surface, they push the water out. Their wings provide lift allowing the gliders to move forward as they change depth. Due to their efficient design, with no need for propellers or an engine, gliders can be deployed for several months at a time."

(2014) Coastal Endurance Array Mobile Assets (CE05MOAS)
An array of ~6 gliders travels along five east-west transect lines within the Coastal Endurance Array from approximately the 20-m isobaths to 126 W (and out to 128 W along the Oregon and Washington lines), as well as a north-south transect along 126 W. Coastal Gliders (Teledyne-Webb Slocum Gliders) fly through the water column along saw-tooth paths, penetrating the sea surface and diving down to depth. These Coastal Gliders are outfitted with one of two buoyancy engines allowing for maximum efficiency for either shallow (able to dive to 200 m) or deep (able to dive to 1000 m) dives. A roughly even combination of deep and shallow diving coastal gliders have been deployed, sufficient to survey the Endurance Array area. Gliders are buoyancy-driven mobile assets. They change their buoyancy by drawing in water through their nose making their front end heavy causing them to sink through the water. To float back up to the surface, they push the water out. Their wings provide lift allowing the gliders to move forward as they change depth. Due to their efficient design, with no need for propellers or an engine, gliders can be deployed for several months at a time.

Two kinds of Mobile Assets survey the area in and around the array of moorings at the Coastal Pioneer Array – Coastal Gliders and Coastal Autonomous Underwater Vehicles (AUVs).\n\nAn array of 6 Coastal Gliders (Teledyne-Webb Slocum Gliders) sample large, mesoscale features through a broad region (130 x 185 km) of the outer continental shelf between the shelf break and the Gulf Stream. The role of these gliders in monitoring this broader area is to resolve rings, eddies and meanders from the Gulf Stream as they impinge on the shelf break front. These Teledyne-Webb Slocum Gliders fly through the water column along saw-tooth paths, penetrating the sea surface and diving down to a maximum depth of 1000 meters.\n\nAn array of two Coastal AUVs (REMUS-600 AUVs) travel along transects across the shelf-break frontal system extending beyond the mooring array, covering an area approximately 80 x 100 km in size centered on the array of moorings. The primary role of the AUVs is to resolve cross- and along-front “eddy fluxes” due to frontal instabilities, wind forcing, and mesoscale variability. These AUVs travel along saw-toothed transects, penetrating the sea surface and diving down to a maximum depth of 600 meters.more » « less
