OSMO Sampler (not cabled)
Osmotic samplers draw hydrothermal fluids into small capillary-like tubing and allow long-term sampling of diffuse and black smoker hydrothermal fluids, as well as fluids from methane seeps. An Osmo Sampler (OSMOIA301) was installed during by the ROV ROPOS on Dive R1730, VISIONS'14, in a diffuse flow site adjacent to the black smoker edifice called Mushroom in the ASHES vent field.
