Osmotic Sampler V15

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.

Osmo samplers were installed in 2014 at the base of the chimney called Mushroom in the ASHES hydrothermal field in the Axial Base (MJ03B) and at the Southern Hydrate Ridge Summit 2 (MJ01B).
