The Coastal and Global Scale Nodes of the Ocean Observatories Initiative

The National Science Foundation´s Ocean Observatories Initiative (OOI) will enable powerful new observing approaches using sustained, controllable observations from an interdisciplinary suite of sensors connected by a robust cyberinfrastructure. The OOI will be implemented via four principle components: Regional Scale Nodes, Coastal and Global Scale Nodes (CGSN), Cyberinfrastructure, and Education and Public Engagement. This paper summarizes the current status of the CGSN infrastructure, which has been under continuous review and refinement since a Conceptual Network Design was presented in 2006.
