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. This data can be used to understand the processes driving methane release and constrain estuarine methane emissions. The porewater data are reported in a separate, related dataset.\n\ncdm_data_type = Other\nVARIABLES:\nSample_ID (unitless)\nSite_Name (unitless)\nStation_ID (unitless)\nlatitude (Latitude_ddeg, degrees_north)\nlongitude (Longitude_ddeg, degrees_east)\nSampling_Date (unitless)\nWater_Depth_m (meters (m))\nCore_Allocation (unitless)\nSediment_Depth_cmbsf (centimeters below sea floor (cmbsf))\nSediment_interval_thickness_cm (centimeters (cm))\nd13C_TOC_permille (per mille (‰))\nCorg_percent (weight percent (wt.%))\nd13C_TON_permille (per mille (‰))\nNorg_percent (weight percent (wt.%))\nComment (unitless)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_1002503_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_1002503_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_1002503_v1/index.htmlTable https://osprey.bco-dmo.org/dataset/1002503 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_1002503_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_1002503_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_1002503_v1
