    • Methane (CH4), Sulfate (SO4 2-), and others collected from E/V Nautilus in NE Pacific and Cascadia Margin from 2020-09-28 to 2020-09-30 (NCEI Accession 0276512)

    Metadata Updated: March 17, 2023

    These data were collected from sediment at two separate ~1000m deep methane seeps on the Cascadia Margin. Sediment cores were collected at the seeps and then at increasing distance from the areas of seepage. This distance is provided in the data set. Sediment plugs were extracted from cores at 3cm intervals. Depth of core indicates the bottom of the depth horizon. Ryzons were inserted at 2cm intervals into adjacently collected cores, and pore water was extracted for Ions, in particular Sulfate and Sulfide. Sediment depth listed is the depth at which the Ryzon was inserted below the surface of the sediment. 0 sediment depth values are from the overlying water collected from the same sediment core. Sediment was also frozen at -80C for later Rare Earth Element (REE) analysis. This sediment was digested in nitric acid and hydrofluoric acid before analysis on the indicated instrument. Sediment depth indicates the depth horizon it came from for REEs, for example 0 for REE equals the 0-1cm fraction and 2 is the 2-3cm sediment fraction.
