Osmotic Fluid Sampler in ASHES
A new osmotic fluid sampler is about to be installed in a diffuse flow site hosting a 3D temperature array in the ASHES Hydrothermal Field on the summit of Axial Seamount. Each year, as part of the annual operations and maintenance cruise, a sampler is recovered and a new one installed. Onshore analyses of the entrapped fluids provide insights on the evolution of fluid chemistry in time, in response to changing environmental conditions e.g. earthquakes, temperature, microbial utilization of gases and different elements.
