Visitors to the Pacific Science Center in Seattle learn about the cabled observatory over an interactive touch screen table. 

Components of the primary nodes include the backbone interface assembly (red frame) and the science interface assembly (yellow).

Secondary nodes will connect to the primary nodes and transfer power and bandwidth to sensor networks. They are scheduled for deployment in 2013 using an ROV. --Graphic credit: OOI RSN and Center for Environmental Visualization, University of Washington

Extension cables will connect the primary nodes to secondary nodes and then to myriad instruments and sensors. Over 22,000 m of extension cables were deployed with the remotely operated vehicle ROPOS during the VISIONS'13 expedition, July - August, 2013.
