A blob sculpin rests near the Tiny Towers vents in Axial Caldera, where the fluid sampling vent cap monitors and collects hydrothermal vent fluids for the PPS (Particulate DNA Sampler), which allows collection, filtering, and preservation of microbial DNA. Credit: NSF-OOI/UW/CSSF, Dive R2246, V22

The titan4 arm of Jason reaches for the osmotic fluid sampler in the ASHES hydrothermal field. Fractures in the lobate lava flows leaking warm fluids support colonies of whte bacteria and small tube worms. The HD video camera is in the background. Credit: UW/NSF-OOI/WHOI. V20

In 2019, a digital-still camera (front-center) and a fluid- and microbial-DNA sampler RASFLA/PPSDNA, inside a seafloor-frame (back-center), were installed in the International District Hydrothermal Field. A titanium vent cap or “hat” (center-middle) rests on top of a hydrothermal-vent structure covered with microbes. Inside the “hat” are temperature probes and intake nozzles for the fluid and DNA sampler. Photo Credit: UW; NSF-OOI; CSSF; DiveJ2-1190; V19
