10.7282/T3VH5QVT Ocean Observatories Initiative Pioneer (Mobile). CP05MOAS-GL, Coastal Glider Ocean Observatories Initiative 2014 Platform assembly containing data collection instruments/sensors on the Pioneer Array, a network of platforms and sensors operating on the continental shelf and slope south of New England in the Atlantic Ocean.Pioneer Array Gliders travel between the Moorings as well as further into the open ocean. The purpose of the Gliders are to sample large scale features associated with the Gulf Stream such as Warm Core Rings. Instead of using propellors, Gliders move through the water column by changing their buoyancy and using their wings to provide lift allowing them to move forward. Due to this efficient design, Gliders can be deployed for several months at a time.An 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.Approximate Glider sampling area boundaries: SE: 39.00°N, 69.92°W SW: 39.00°N, 71.50°W NW: 40.67°N, 71.50°W NE: 40.67°N, 69.92°WGliders 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.Coastal Gliders (Teledyne-Webb Slocum Gliders) deployed at the Pioneer Array fly through the water column along saw-tooth paths, penetrating the sea surface and diving down to a maximum depth of 1000 meters.
