The Regional Cabled Array includes ~900 km of submarine high power and bandwidth fiber optic cables connected to 7 Primary nodes [underwater substations, 18 secondary nodes, and >150 instruments streaming live data to shore 24/7. Six cabled and instrumented moorings span depths from 2900 m to 600 m with instrumented science pods that travel up and down through the water column, also streaming live data. The high bandwidth and power provides important expansion opportunities for interested investigators. Credit: University of Washington.
