Title: (2013) Global Station Papa Mobile Assets (GP05MOAS)
Station Papa 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 Station Papa Apex Profiler Mooring.\nGliders 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.  more » « less

    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.

    The Station Papa array has two identical Flanking Moorings that make up the equidistant sides of a triangle of Moorings (40 km) from the co-located Profiler and Surface Moorings. They are located in 4,250 meters in the Gulf of Alaska in the NE Pacific. The triangular configuration moorings provide unique spatial array through which instruments fixed to moorings continuously collect data through time and gliders sample the area between the moorings. The Station Papa site is one of four high latitude open ocean locations in the OOI that provide observations to gain better insight into global ocean circulation and climate.\nLike other Flanking Subsurface Moorings, the Station Papa Flanking Subsurface Moorings contain instruments fixed at specific depths along the mooring riser throughout the water column to a depth of 1,500 meters. The flotation buoy for these subsurface moorings is located 30 meters below the sea surface. As they have no surface expression, these moorings communicate and send data to shore via an acoustic link to nearby gliders.
