attribute NC_GLOBAL summary String These data include incubation timepoint measurements of concentration and stable carbon isotope values of dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and particulate organic carbon (POC) from sediment cores collected at a methane seep and associated reference site (Southern Hydrate Ridge) and a submarine canyon (Astoria Canyon). Sediment porosity and dissolved sulfate and methane concentrations are also presented. These data were collected from 2023-2024 and across two cruises: AT50-14 (R/V Atlantis, 2023) and AT50-29B (R/V Atlantis, 2024). These data are used to assess the mechanism contributing to the production of methane-derived DOC across several environments. If this process occurs at a methane seep mediated through anaerobic oxidation of methane, the process should occur in other sedimentary environments in which these electron acceptors are available. At methane seeps, this produced DOC which may contribute to benthic food webs or contribute to the apparent radiocarbon age of deep  ocean dissolved organic carbon.
