Flanking Subsurface Mooring B (GI03FLMB)

The Irminger Sea array has two identical Flanking Moorings that make up the equidistant sides of a triangle of Moorings (20 km) from the co-located Profiler and Surface Moorings.  They are located in 2,800 meters of water southeast of Greenland in the North Atlantic.  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 Irminger Sea 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 Irminger Sea Flanking Subsurface Moorings contain instruments fixed at specific depths along the mooring riser throughout the water column to a depth of 2,600 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.
