Bathymetric map of Southern Hydrate Ridge showing core OOI Cabled Array infrastructure and instruments as installed in 2017. The main study site is focused on Einsteins' Grotto that is highly dynamic with explosive bubble plumes and large collapse zones that have formed since 2010. Credit: M. Elend, University of Washington.

Cabled Array infrastructure at the Oregon Offshore Site as installed in 2017. The site was trawled fall 2017: the Shallow Profiler Mooring (PC01B-SC01B) will be reinstalled during the Cabled Array 2018 field program. Credit: M. Elend, University of Washington.

Cabled infrastructure at the Oregon Endurance Shelf site, in 80 m of water, obtains power and communications from Primary Node PN1D located ~ 17 km to the west. The site is impacted by strong currents with very turbid water due to high productivity. Credit. D. Kelley and CEV, University of Washington.

Cabled Array core infrastructure and instruments at the summit of Axial Seamount. Also shown in yellow are new instruments funded by the National Science Foundation (COVIS sonar,self calibrating pressure sensor, and flipping tilt meter) and an 3D temperature array platform that will be installed this year, followed by the instrument array next year funded by the Office of Navy Reserach.

Perspective view of Cabled Array infrastructure at the base of Axial Seamount  (~2600 m water depth).

The National Science Foundations' Ocean Observatories Initiative Regional Cabled Observatory spans the Juan de Fuca tectonic plate. Two high power and bandwidth submarine fiber optic cables (900 km total in length) link to Axial Seamount and to several margin sites off of Newport Oregon.

A Shallow Profiler winched science pod and stationary platform, which host 18 instruments (e.g. pH, CO2, temperature, chlorophyll, zooplankton, nutrients, currents) undergoes testing in the School of Oceanography saltwater tank. The platforms will be deployed 600 ft beneath the oceans surface. Since 2015, three of these pods have made >27,000 profiles, providing unprecedented measurements of our dynamic ocean in real-time.
