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.

Organisms colonize the outer walls of the 16 m-tall hydrothermal edifice called El Guapo. The community structure 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.

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.

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.

Every year when we are diving in the International District Hydrothermal Field, very large fish, ~ 4 feet! in length come to investigate what we are doing. They swim slowly in the 2.4°C waters. 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.

During Leg 1 (RR1809) of the NSF-funded Cabled Array cruise, there were 10 student participants from the University of Washington. From Left to Right: Deb Kelley (Chief Scientist and Instructor), Rachel Scott, Brittney Slucher, Eve Hudson, Katie Keil, Julie Nelson (Professor at Grays Harbor College and Scientist on the OOI cruise), Leroy Miller, Kaite Gonzalez, Bing-Yu Lee, and Terrie Manning.

Once again the Smokey Caverns (or Taverns as it is also known) has changed remarkably since we visited it with Jason last year. The area is significantly more rugged, marked by large hummocks. An eelpout, sole, clams and orange rock fish dot the landscape. Credit: UW/NSF-OOI/WHOI, V18.

A rattail fish (Grenadier) investigates two pressure sensors at 9500 ft water depth at the sedimented Slope Base site. The one in the background has been equilibrating since 2017 on the seafloor. Venus fly-trap like anenomies have colonized the cables that allow data to flow to shore in real-time, and a feeding sea star is on the dusty, 2014 sensor. Credit: UW/NSF-OOI/WHOI, V18.

Einsteins Grotto, the active methane seep first visited by the UW in 2010, continues to surprise us - this year, multiple bubble streams were issuing from the pit and exposed methane hydrate was documented in the sides of the wall. Credit: UW/NSF-OOI/WHOI, V18.

An instrumented "Platform Interface Assembly" from the Slope Base site is recovered onto the deck of the R/V Revelle during the OOI-NSF Cabled Array expedition lead by the University of Washington. The platform was attached to a 7,000 lb, 12 ft across mooring platform at 200 m beneath the suface. Attached to the cable it host 18 instruments sending live data to shore 24/7. Credit: M. Elend, University of Washington, V18.
