During ROPOS Dive R1729, a digital-still camera (left), a mass spectrometer (middle) and a fluid- and microbial-DNA sampler (right) were installed in the International District Hydrothermal Field at the vent called El Gordo. A titanium 'hat' rests on top of the structure in a tubeworm and limpet patch. Inside the hat are temperature probes and intake nozzles for the fluid and DNA sampler.

A huge rattail fish followed the ROV ROPOS around the International District hydrothermal field for several hours. Near the end of the dive it investigated the tool basket, with thoughts that it might get in. Photo credit: UW/NSF-OOI/CSSF; ROPOS Dive 1729; V14.

This species is not yet identified, although it may also be Spinophiura jolliveti.  It is the dominant brittle star at the base of Axial.  Photo credit: NSF-OOI/UW/CSSF; R600; V13

Hundreds of Spinophiura brittle stars can be found clinging to nearly all lava flows within Axial Seamount's caldera. Photo credit: NSF-OOI/UW/CSSF; Dive R1635; V13
