Southern Ocean Flanking Mooring A

"The Southern Ocean array has two identical Flanking Moorings that make up the equidistant sides of a triangle of Moorings (50 km) from the co-located Profiler and Surface Moorings. They are located in 4,800 meters of water in the Southern Ocean, SW of Chile. 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 Southern Ocean 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.
Like other Flanking Subsurface Moorings, the Southern Ocean 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."
