The camera was reinstalled in the ASHES hydrothermal field during Leg 2 of the Cabled Array OOI-NSF VISIONS17 cruise. The structure is ~ 3.5 m tall and covered in tube worms, limpets, scaleworms and palmworms. This camera has a brush on it so that it can clean its 'face' of biofouling. Credit: UW/OOI-NSF/WHOI; V17.

A sytrofoam head (left) provided by the Clallam Bay School, Washington was taken down to ~9500 ft. It stands next to a "normal sized" styrofoam head designed by Tracie Barry, a previous VISIONS' student. At this depth, the pressure of the overlying ocean is almost 300 times that on land.

The intake for an Osmo fluid sampler is installed during VISIONS'17. Very small diameter tubing is filled with fresh water; seep fluids are drawn into the tubing osmotically. The fluids will later be analyzed onshore to examine the evolving chemistry of methane seeps. Credit:UW/OOI-NSF/WHOI; V17.

A Mosquito, developed by UW Marine Geologist, Evan Solomon, is deployed at a methane seep at Southern Hydrate Ridge. The instrument pulls in fluids in the sediments with a tracer. The instruments are recovered annually and the fluid chemistry analyzed, providing calculations of the flow of fluids both into, and out of the seafloor. Credit: UW/OOI-NSF/WHOI; V17.

The image is enrapturing. Microorganisms swirl and pulse with activity. A salp (bottom right) drifts idly through a sea green with phytoplankton. Comb jellies slide gracefully by, rainbow lines radiating from their cilia. We joke it is the perfect setting for a screensaver. Credit: K. Eyer, Kingston Middle School, V17.

A "snow storm" of material in the shallow waters (80 m) off of Newport, Oregon prevented the ROV Jason from recovering and redeploying the Bethic Experiment Platform during the first two dives of the VISIONS'17 program. These waters are some of the most biologically productive in the worlkds' oceans. Credit: UW/OOI-NSF/WHOI; V17.
