Apex Surface Mooring (GA01SUMO)

The Argentine Basin Apex Surface Mooring is co-located with Apex Profiler Mooring.  Additionally, at the Argentine Basin site are two identical Flanking Subsurface that make up the equidistant sides of a triangle of Moorings (62 km) from the co-located Profiler and Surface Moorings.  The Surface Mooring is located in 5,200 meters of water along the Brazil Current in the South 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 Argentine Basin 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.  In particular instruments on the Surface Buoy will provide key insights into climate dynamics associated with air-sea fluxes.

Like other Open Ocean Surface Moorings, the Argentine Basin Apex Surface Mooring is specifically designed to examine global phenomena as well as withstand rough sea conditions associated with high latitude, deep, open ocean sites. The Surface Mooring contains instruments attached to a Surface Buoy floating on the sea surface, Near Surface Instrument Frame 12 meters below the surface, and instruments attached to the Mooring Riser at fixed depths through the water column. The Surface Buoy provides a platform on which to secure surface instruments above the sea surface, below the sea surface, and across the interface between. Additionally the Surface Buoy contains an antenna to transmit data to shore via satellite.
