Hi Tom,
The southern line of the Regional Cabled Array, which connects to the Oregon Offshore and Shelf sites of the Endurance Array, starts at the same shore station as the northern line in Pacific City, OR. The northern line runs west across the Juan de Fuca Plate to Axial Seamount, sending power and delivering real-time data from the volcanic caldera and instruments at the base of the seamount. The Southern line extends south to connect to a site at the base of the Continental Slope (2900 meters water depth), then runs back upslope to Southern Hydrate Ridge, where instruments record data on the methane seeps and chemosynthetic communities, and then further east to the Oregon Offshore site (which has two cabled water column profiler moorings and seafloor instrumentation at 600 m) and finally the Oregon Shelf site (which hosts a bioacoustic sonar platform, cameras, and other seafloor sensors at 80 m to complement the uncabled surface moorings and glider deployments). The northern and southern lines are separate in terms of primary power and bandwidth, but both are monitored and powered from the Pacific City shore station and maintained by the University of Washington.
Please let us know if you have any other questions about the design or operation of the OOI Regional Cabled Array.
Thanks,

I am curious why Endurange array cable has a big loop?
