The cabled Seafloor Instrument Array is associated with the paired Shallow and Deep Profilers and will document near-bottom and water-column processes. Instruments include the following: 150-kHz ADCP, Broadband Hydrophone, Acoustic Modem, Optical Attenuation, CTD, Dissolved Oxygen, and a HPIES (Horizontal Electric Field, Pressure and Inverted Echo Sounder).
In 2014, this array is anticipated to be installed with the profilers at the base of the Cascadia Margin (Slope Base), in shallower waters along the Oregon margin west of Newport (Endurance Array), and at the base of Axial Seamount.
