Sampling Hydrothermal Fluids From Axial Seamount

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.

Limpets and Scale Worms

Community structure on the 16 m-tall hydrothermal structure 'El Guapo' changes with height above seafloor. Here, limpets, red scale worms and blue protists (ciliates) colonize the outer sulfide walls of the structure. Credit: UW/NSF-OOI/WHOI, V18.

Life on El Guapo

Near the summit of the ~16 m-tall El Guapo chimney, sulfide worms  and tubeworms colonize the younger part of the new sulfide growth. Credit: UW/NSF-OOI/WHOI, V18.

How Fast do Vent Fluids Flow

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.

Mushroom Orifice Booming

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.
