Design, construction, and early operation of the OOI Cabled Array, located off the coast of Oregon and Washington, has been led and implemented primarily by oceanographers and engineers at the University of Washington. At-sea construction was completed between 2011 to 2014.
More than 100 instruments and six instrumented moorings are now directly connected to land-based communications via the Cabled Array's 975-km network of primary and secondary cables, which provide high-power capabilities of 8–10kW and communications bandwidth of 10 Gbs. Data are flowing from most of the instruments installed on the system.
Annual maintenance cruises will refurbish and service the cabled network for the coming decades as scientists, educators, and the public learn to use this novel capability of being present throughout entire volumes of the ocean, without actually being there. The sensor-robot systems can be operated from land and cameras provide visual contact with actual processes unfolding offshore. As this approach matures, complex experiments will be conducted using remotely operated robotic-sensor systems controllable from land.
