The Cabled Continental Margin Array portion of the Regional Cabled Array spans coastal to blue-water environments and includes electro-optical submarine cables that provide high power, bandwidth, and two-way real-time communication to seafloor and water column instrumentation. Within the Continental Margin Array, infrastructure is located just off the continental slope near the Cascadia subduction zone, on the continental slope at Southern Hydrate Ridge (an area with methane hydrates), and then connects further up the slope to the Endurance Array Oregon Line at the Offshore, and Shelf sites.
Three Junction Boxes located at the Southern Hydrate Ridge site contain geophysical instruments (seismometers and hydrophones), as well as sensors to image and measure the rising plumes, the flow of fluid into and out of the seafloor, and fluid chemistry. At the Slope Base, observations are made from the seafloor to near the sea surface using Junction Boxes hosting geophysical instruments and those focused on water column processes. These are paired with a Cabled Deep Profiler Mooring and a Cabled Shallow Profiler Mooring. All instrumentation and infrastructure are connected to the cable for power and communication, ultimately making possible real-time data flow.
