Power systems for the Coastal and Global Scale Nodes of the Ocean Observatories Initiative

The Ocean Observatories Initiative (OOI) includes mooring power systems development for the Coastal and Global Scale Nodes (CGSN). This paper summarizes the current status and results of the CGSN power systems development effort primarily concentrating on the surface moorings which include wind generators, photovoltaic arrays, rechargeable batteries and power control electronics. Higher power versions of these mooring power systems, currently in the design phase, are also described.
