attribute	NC_GLOBAL	sourceUrl	String	(local files)
attribute	NC_GLOBAL	Southernmost_Northing	double	37.20699
attribute	NC_GLOBAL	summary	String	These data include vertical profiles of concentrations and stable carbon isotope values of methane, carbon dioxide, dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and total organic carbon (TOC) from porewater of sediment cores collected at methane seeps and reference sites. Sediment porosity and dissolved sulfate and chloride concentrations are also presented. Gravity cores (1 meter) were collected from the mainstem of Chesapeake Bay from July 25-29, 2022. These data are used to assess the distribution, source, and fate of methane in a eutrophic shallow-water estuary, which is a source of methane to the atmosphere. These data can be used to understand the processes driving methane release and constrain estuarine methane emissions. The sediment data are reported in a separate, related dataset.
