The Pioneer Central Surface Mooring is located on the Continental Shelf, approximately 130 meters deep. The Continental Shelf-Slope area off the New England coast is a highly productive area and one that is located at a dynamic intersection where ocean currents meet in weather-like “fronts,” and where nutrients, pollutants, and other properties are exchanged between the coast and the deep ocean. Data from the shelf area help to examine exchanges between the shelf and slope and the shelf ecosystem, as well as provide broader insight into the issues of air-sea gas exchange, including Carbon Dioxide.\nLike other Coastal Profiler Moorings, the Pioneer Central Inshore Profiler Mooring contains a Wire-Following Profiler that houses instruments. The Wire-Following Profiler moves through the water column along the mooring riser, continuously sampling ocean characteristics over a specified depth interval. 

The Pioneer Inshore Profiler Mooring is located on the inner Continental Shelf, approximately 90 meters deep.

"The Southern Ocean Surface Mooring is co-located with Southern Ocean Profiler Mooring at the Apex site. Two identical Flanking Moorings make up the equidistant sides of a triangle of Moorings (50 km) from the Apex site. The Surface Mooring is 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. In particular instruments on the Surface Buoy will provide key insights into climate dynamics associated with air-sea fluxes. The Southern Ocean 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 antennas to transmit data to shore via satellite." 

Argentine Basin 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 Argentine Basin Apex Profiler Mooring.Gliders 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. 

The Argentine Basin array has two identical Flanking Moorings that make up the equidistant sides of a triangle of Moorings (62 km) from the co-located Profiler and Surface Moorings. They are 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.\nLike other Flanking Subsurface Moorings, the Argentine Basing 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.

The Coastal Endurance Washington Shelf Surface Mooring is located on the Continental Shelf, approximately 90 meters deep. The Continental Shelf-Slope area off the Washington coast is a highly productive, dynamic upwelling environment. Upwelling brings nutrients to the surface sparking primary production and fueling the food web. In recent years, upwelling has also brought onto the shelf hypoxic, low oxygen, waters that can be harmful to organisms in the area. By sampling in this area, the OOI seeks to gain better insight into upwelling dynamics of this system.\nLike other coastal moorings, the Coastal Endurance Washington Shelf Surface Mooring is specifically designed to examine coastal-scale phenomena and withstand the challenging conditions of shallow coastal environments, including large tidal fluctuations. The Surface Mooring contains instruments attached to a Surface Buoy floating on the sea surface, Near Surface Instrument Frame 7 meters below the surface, and a Seafloor Multi-Function Node (MFN) located on the seafloor. 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. 

The Coastal Endurance Washington Inshore Surface Piercing Profiler Mooring is located on the inner Continental Shelf, approximately 29 meters deep. The Continental Shelf-Slope area off the Washington coast is a highly productive, dynamic upwelling environment. Upwelling brings nutrients to the surface sparking primary production and fueling the food web. In recent years, upwelling has also brought onto the shelf hypoxic, low oxygen, waters that can be harmful to organisms in the area. By sampling in this area, the OOI seeks to gain better insight into upwelling dynamics of this system.\nLike other Surface Piercing Profiler Moorings, this mooring contains a Surface-Piercing Profiler that allows for the sampling of near surface phenomena as the Profiler travels through the water then breaches the surface. Fine resolution sampling of the water column, particularly at the very surface of the water, provides key insights into the exchange of gases, heat, etc. between the atmosphere and the ocean. While on the surface, the profiler transmits data to shore.
