The Osmosis-Based Water Sampler provides long-term sampling of diffuse and/or pore fluids at the seabed by drawing those fluids into small-bore, capillary tubing. The instrument currently deployed at Southern Hydrate Ridge samples pore fluids associated with methane seeps, while the instrument at the ASHES vent field on Axial Seamount is collocated with the 3-D Temperature Array (TMPSF) and samples diffuse fluids associated with hydrothermal flow. After instrument recovery, laboratory analyses provide major/trace element chemistry of these fluid samples.
The laboratory processed analytical data and metadata from the fluid samples can be found in the OOI Core Instrument Analytical Results data repository. Numerical and other processed analytical results are generally provided in spreadsheet form. Associated metadata files including analytical protocols, sampling and recovery notes, and sample log files are presented in .pdf format. As-deployed images of instruments are provided in .jpg format, with image metadata summarized in spreadsheet-based catalogs.
