The Global Class research vessel, the R/V Roger Revelle, is operated by Srcripps Institution (SIO) of Oceanography. It will be utilized for the Cabled Array operations and maintainence cruise July - August, 2017. This image is from the SIO website.

Young explorers at the Seattle Aquarium's Discover Science event view brittle stars imaged at depths of 2900 m during a Cabled Array cruise. Dana Manalang and Brendan Philip, part of the UW Cabled Array team share the excitement of exploring and instrumenting the deep. 

Dana Manalang (Applied Physics Laboratory engineer) and Brendan Philip (School of Oceanography graduate student) share the marvels of deep sea exploration and the underwater cabled observatory at the Seattle Aquarium's Discover Science Event 2016.

LED lights on the high definition camera, built by the Applied Physics Laboratory at the University of Washington, light up a ~1 m tall, young black smoker chimney at the base of the actively venting Mushroom edifice on Axial Seamount (water depth ~1500 m). The image, taken with the ROV Jason, shows the camera being tested by UW engineers during VISIONS16. They were in the Operations Center, located 300 miles to the east at the School of Oceanography. Here, they were commanding/controlling the camera live through the terrestrial and submarine Internet as part of the NSF Cabled Array infrastructure. Credit: UW/NSF-OOI/WHOI; V16.

A new osmotic fluid sampler is about to be installed in a diffuse flow site hosting a 3D temperature array in the ASHES Hydrothermal Field on the summit of Axial Seamount. Each year, as part of the annual operations and maintenance cruise, a sampler is recovered and a new one installed. Onshore analyses of the entrapped fluids provide insights on the evolution of fluid chemistry in time, in response to changing environmental conditions e.g. earthquakes, temperature, microbial utilization of gases and different elements.

The ROV Jason 'looks' at a hybrid underwater wet-mate connector that connects the high definition camera to a ~ 4 km long extension cabled attached to Primary Node PN3B at the summit of Axial Seamount. This connection provides a 10 Gbs communication path to the terrestrial Internet located ~300 miles to the east. White bacterial mats line fractures in the lava-covered seafloor where diffusely flowing fluids are exiting the seafloor. Credit: UW/NSF-OOI/WHOI; V16.

The high definition camera, built by the UW Applied Physics Lab, was reinstalled in 2016 during the VISIONS'16 cruise. The prior camera had been streaming video live to shore for two years. The camera was recovered to clear the outer window of biofouling. The camera is located at the hydrothermal chimney called Mushroom in the ASHES hydrothermal field on Axial Seamount. Video are streamed live from ~5000 ft down and >300 miles offshore onto the Internet 8 times a day. Credit: UW/NSF-OOI/WHOI; V16.

A 3D temperature (thermistor) array housing 24 sensors rests above a small diffuse flow site a few meters away from the actively venting black smoker edifice called Mushroom in the ASHES hydrothermal field on Axial Seamount. This cabled instrument was designed and built by G. Proskurowski, UW School of Oceanography. Limpets have colonized the frame and cable housing the thermistors. An osmotic fluid sampler is inserted into the diffuse flow site to obtain chemistry coregistered with temperature. Credit: UW/NSF-OOI/WHOI; V16. 

A titanium isobaric gas-tight sampler (IGT) is used to sample fluids with dissolved gases in a high temperature vent on the El Gordo metal sulfide chimney located in the International District Hydrothermal Field at ~ 1500 m water depth on Axial Seamount. The base of the cabled RAS fluid sampler and microbial DNA sampler mooring is in the background. Credit: UW/NSF-OOI/WHOI; V16.

The cabled digital still camera streams images of Jason (Dive J2-932) live back to shore in real time as the vehicle works at the active hydrothermal vent called 'El Gordo' in the International District Hydrothermal Field - depth is 1500 m, and >300 miles offshore. The hydrothermal fluid sampler, called the RAS, is shown to the left, which allows fluid samples and temperature to be taken for a year. The instrument can be run in "mission mode" where samples are preprogrammed, or in "sponse mode" where missions are interrupted by operators to take samples - such as was done during the eruption of Axial Seamount in 2015.

An HPIES instrument deployed off the starboard side of the R/V Sikuliaq ~ 125 km offshore Newport Oregon near the base of the Subduction Zone at Slope Base. The instrument was released and free fell 2900 m to land softly on the seafloor - the extended legs insure a softer landing and that is stays nearly horizonatal as it travels through the water column. 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.

Hagfish investigate flow meters called Mosquitos at methane seeps at Southern Hydrate Ridge (water depth ~800 m). Data from these instruments allow calculation of the flux of fluids into and out of sediments at this gas hydrate site marked by thick bacterial mats and abundant clams.

The BEP at the Oregon Shelf site is in highly productive waters. It provides a protective habitat and hard substrate for biological communities to grow on, including large sea anemones that have colonized this platform in the 1-year it has been installed. Credit: UW/NSF-OOI/WHOI; V16.

These data are put into mapping programs to insure that the sound velocity profile is accurate for a given location. Credit: M. Elend, University of Washington, V16.
