The Coastal and Global Scale Nodes (CGSN) component of the OOI is being developed and constructed by Woods Hole Oceanographic Institution, Oregon State University and Scripps Institution of Oceanography.
The coastal component is comprised of two arrays: Endurance Array located in the Northeast Pacific and Pioneer Array off the mid-Atlantic coast. The global component includes four high latitude sites: Irminger Sea off Greenland, Argentine Basin off the coast of Argentina, Southern Ocean at 55°S, 90°W, and Ocean Station Papa in the Gulf of Alaska.
Coastal arrays extend from the highly productive continental shelf to across the continental slope, allowing scientists to examine several important coastal processes including upwelling, hypoxia, shelf break fronts, and the role of filaments and eddies in cross-shelf exchange. Technologies will be employed to gather data in the coastal region including moored buoys with fixed sensors, moorings supporting vertical profilers, seafloor cables, gliders and autonomous underwater vehicles. The global sites each include four moorings composed of fixed and moving sensors that measure air-sea fluxes of heat, moisture and momentum as well as physical, biological and chemical properties.
