Acoustic Doppler Current Profiler V17

Acoustic Doppler Current Profiler Installed
Cleaning the ADCP

Katie Gonzalez, from Clallam Bay, will be a freshman at the University of Washington Fall 2017 where she will study Oceanography and work with Deb Kelley. 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.

ADCP

ADCP (acoustic doppler current profiler) mounted on benthic platform.

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.

Vertical beam ADCPs are also planned for deployment at Slope Base (PC01A) and Axial Base (PC03A)
