An HPIES instrument is being installed off the starboard side of the R/V Sikuliaq ~ 125 km offshore Newport Oregon near the base of the Subduction Zone. This instrument utilizes a bottom pressure sensor, an inverted echosounder and a horizontal electrometer to provide insights into the vertical structure of current fields, near-bottom water currents, and water properties including temperature, salinity, and specific volume anomalies. It was built at the Applied Physics Laboratory. Credit: M. Elend, University of Washington, V16.
