Acoustic Doppler Current Profiler

A variety of geophysical sensors will be deployed at the base of Axial Seamount to monitor seismic events on the Juan de Fuca plate.

An Acoustic Doppler Current Profiler (ADCP) provides a 3D water-current velocity for a small volume of the overlying water column by making very high-frequency acoustic (75- to 600-kHz) doppler shift measurements.

These instruments are now installed at Slope Base PN1A (150 kHz), Axial Base PN3A [(150 kHz) shown above], and at the Oregon Offshore PN1C (75 kHz) Site.
