Description:

Abstract:

Geochemical analysis of sediment core pore fluids collected from seep fields on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019. Samples were collected to deconvolve the different processes impacting the fluid chemistry, including hydrate dissociation and clay mineral dehydration during the smectite-illite transformation that releases inter-layer water.

Purpose:

These samples were collected and analyzed as part of an effort to map, quantitative survey, and sample seafloor benthic communities, associated sediment infauna, and motile organisms near seeps; characterize the physics and chemistry of sediments at seep locations and in the farfield; and geochronologic studies of authigenic carbonates to constrain the timing of methane seepage events as part of the CaMMeRA (Cascadia Margin Methane Research Action) project.

Source_Contribution:

Sulfide samples were analyzed spectrophotometrically following the methylene blue method (Cline SiL 1969; Reese and others, 2011) using a Thermo Scientific GENESYS 20 spectrophotometer (1 cm cell, 670 nanometer wavelength). The detection limit was determined as 2 times the concentration of the reagent blank (Reese and others 2011) or LOD =1 micromolar. Quality assurance included replicate analysis of prepared standards and field samples. Average coefficient of variation of replicates for this sample set was less than 1 percent.

Source_Contribution:

Dissolved anion concentrations, chloride (Cl-) and sulfate (SO42-) were analyzed using a DX-120 ion chromatograph ion chromatograph at Monterey Bay Aquarium Research Institute (MBARI). Pore water samples were filtered through 0.22 micron filters, diluted 1:100 with milli-Q water, and injected into a Dionex DX-120 ion chromatograph. Bracketing standards were run every five samples. Long-term reproducibility of Cl- and SO42-concentration measurements is 3.2 percent (2 sigma).

Process_Step:

Process_Description:

Sediment push cores were collected using the remotely operated vehicle (ROV) SuBastian (Schmidt Ocean Institute) and pore fluids were extracted using Rhizon samplers (0.15-micron pore size). Pore fluid samples were analyzed by several different labs (see Sources) for different variables. Data from all lab analyses were combined into a single document. -9999 cell value indicates no data (for example, where water sample was not analyzed for a particular variable given sample volume limitations).
