Hydrate Ridge Primary Node (PN01B), is located on the continental shelf west of Newport Oregon at a water depth of 1237 m. It is connected to the land-based shore station in Pacific City, Oregon via a fiber-optic cable. Primary Node PN1B provides power and bandwidth to the Southern Hydrate Ridge study site via an ~ 10 km long extension cable. It also feeds Primary Nodes PN1C and PN1D farther upslope. Primary Nodes convert high power (10 kW) from the shore station to a lower power (375 v) and distribute that power and communication to junction boxes within the Cabled Array through their science ports. Primary Nodes also receive data and communications from the junction boxes which they transmit back to shore.
Primary Node (PN01B) provides power and bandwidth to the following infrastructure on the Southern Hydrate Ridge Summit:
