UW Oceanographer Mitch Elend (L) and Co-Chief Scientist Orest Kawka remove samples of hot spring fluids collected 2017-2018 in the remote acces fluid sampler that was capturing fluids from the Tiny Towers diffuse flow site in the International District Hydrothermal Field at the summit of Axial Seamount.

A flow meter for hydrothermal vents is deployed at the small Diva chimney, held in the arm of Jason. Here, fluids are issuing the anhydrite-rich structure at ~ 290°C. The flow meter was designed by Leonid Germanovich, Clemson University. Credit: UW/NSF-OOI/WHOI, V18.
The orifice at the base of the hydrothermal chimney called Mushroom is marked by a strong jet of high temperature hydrothermal fluid. Sulfide worms, scale worms and limpets are bathed in a mixture of the high temperature fluid and seawater. Credit: UW/NSF-OOI/WHOI, V18.
