<p>Axial Seamount 2015 ROV sample metadata for TN327.&nbsp;</p>

<p>Fluid samples for water and gas chemistry were collected from the ROV Jason with titanium major samplers manufactured at WHOI, with UCSB-type titanium gas-tight samplers designed and manufactured by John Lupton and Conrad Young, and with the Hydrothermal Fluid and Particle Sampler (HFPS) designed by David Butterfield and manufactured at NOAA-PMEL. A subset of HFPS samples were filtered in-situ through acid-washed 0.4 micron polycarbonate membrane filters during sampling. In-situ filters with RNA preservative were collected with the HFPS. Samples for water chemistry are in custody of D. Butterfield. Extracted gas samples are in custody of J. Lupton and M. Lilley. RNA/DNA samples are in custody of J. Huber.</p>
