An instrument, known as the Universal Fluid Obtainer (UFO), used by PI Dr. Rika Anderson (Carleton College) to collect and filter water from a diffuse flow vent in the International District at Axial Seamount. The vent itself is surrounded by blue ciliates. Credit: UW/NSF-OOI/CSSF, Dive R2213, V22.
