attribute NC_GLOBAL summary String These data include vertical profiles of concentrations and stable carbon isotope values of dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and total organic carbon (TOC) from sediment cores collected at methane seeps and reference sites. Sediment porosity and dissolved sulfate and methane concentrations are also presented. Methane seeps in Astoria Canyon and Hydrate Ridge along the Cascadia Margin were sampled. These data were collected over two years and across two cruises: AT50-14 (R/V Atlantis, 2023) and AT50-29B (R/V Atlantis, 2024). These data are used to assess the prevalence of methane-derived DOC at methane seeps, which may contribute 'old' carbon to the deep ocean or serve as a source of reduced carbon for the deep ocean microbial loop.
