Cabled infrastructure now installed at Southern Hydrate Ridge providing real-time data to shore. The main focus site is called 'Enstein's Grotto, a site where vigorous venting of methane bubbles rise several hundred meters above the seafloor. Credit: University of Washington.

The cabled coastal surface-piercing profiler (cCSPP) was delivered to the seafloor by ROPOS and placed roughly 12 meters due East of the medium-powered junction box MJ01C at the Oregon Shelf site, in 79 meters of water. The cylindrical sensor pod of the cCSPP (left side of image) will float freely in the water column after being released from the deployment cradle on the profiler base. Once powered up, the sensor pod will move up and down in the water column at least 4 times per day, taking samples continuously using the onboard CTD, oxygen, fluorometer, nitrate, AC-S, PAR sensor, spectral irradiance, and 3D water velocity sensors.   Photo Credit: NSF/UW/CSSF, Dive R1801, V14

An orange anemone clinging to the hydrophone cable at the Oregon Shelf site. The hydrophone was only deployed roughly a week before, so this anemone found the hard substrate and attached itself fairly quickly.   Photo Credit: NSF/UW/CSSF, Dive R1801, V14
