Life thrives on the Shallow Profiler Mooring platforms at 200 m beneath the oceans' surface. This 12 ft across mooring platform is coated in dense communities of very large anenomes, small pink sea urchins, feathery brown crinoids , and small crabs and shrimp...the closer you look the more you see.

This science pod was cut loose from the Axial Base Shallow Profiler mooring on Sunday morning and was throughly cleaned by an eager group of students. The growth visible on the pod comes after just one year in the water, and since many of the instruments on the pod require unobstructed intake lines for sampling, the pods must be replaced yearly.

Columns in a collapsed area that once hosted a lava lake are reminiscent of an ancient city. Rings mark lowering of the lake as lava drained out. Fossilized drips of lava are preserved hanging from the ceiling. A rattail fish explores the site. This is part of the 2011 eruption at Axial. Credit: UW/OO-NSF/WHOI; J2-980; V17.

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.
