The Ocean Observatories Initiative (OOI) Regional Scale Nodes (RSN) Team, located at the University of Washington, has provided an update on the current status of the Secondary Nodes Systems for the OOI.  The Secondary Nodes serve as the bridge between the RSN instruments and the Primary Infrastructure. A successful Critical Design Review (CDR) for the RSN Secondary Nodes subsystem took place on November 21, 2011, at UW’s Applied Physics Laboratory. Comprised of low- and medium-power junction boxes and low-voltage nodes, these components convert the 1 Gb/s bandwidth and 375dc voltage from the Primary Nodes to the native interfaces needed by the scientific instruments.
