The cabled Deep Profiler vertical moorings host an instrumented Mclane profiler vehicle modified by the UW Applied Physics Laboratory for enhanced capabilities on the Cabled Array. The vehicle houses a suite of instruments to measure ocean properties from ~2900 m to ~ 150 m water depth. Power and data transfer are provided via an inductive couple, augmented by WiFi capabilities for lower data rate transfers. The following instruments are included on the Deep Profiler: CTD, Dissolved Oxygen, 3-D Single Point Current Meter -Temperature, and Fluorometers (CDOM, Chlorophyll-a, Optical Backscatter).
There are three Deep Profiler Vertical Moorings on the Cabled Array. They are each paired with a Shallow Profiler Mooring and a Seafloor Instrument Array. Two are currently installed at the base of the Cascadia Margin (Slope Base -PN1A) and in shallower waters along the Oregon margin west of Newport (Endurance Array Offshore Site – 600 m). During the VISIONS'18 cruise, we will turn two of the already deployed moorings, and install an additional one near the base of Axial Seamount near PN3A (~2700 m).
