Here, she is cleaning an Acoustic Doppler Current Profiler recovered from 2900 m water depth at the Slope Base site. Credit: M. Elend, University of Washington.
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.
5-Beam Vertical beam ADCPs are also installed at Slope Base (PC01A) and Axial Base (PC03A)
