​The Juan de Fuca Mid-Plate Primary Node (PN05A), is located on the Juan de Fuca Plate between Axial Seamount and the shore. As with other Primary Nodes, PN5A rests on the seafloor and is connected to the land-based shore station in Pacific City, Oregon via fiber-optic cables. Primary Nodes convert high power from the shore station to a lower power 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.

This site is not currently instrumented, so it contains no science sensors.
