The vials were frozen and returned to the shore-based lab at Old Dominon University (ODU) where the samples were dried to constant weight and wet-to-dry sediment ratios were converted to porosity values. These samples were collected as part of a larger project examining deaminated peptides and organic matter cycling in the sediments at these sites.\n\ncdm_data_type = Other\nVARIABLES:\nShip (unitless)\nCruise_ID (unitless)\nSt_ID (unitless)\nlatitude (Station_latitude, degrees_north)\nlongitude (Station_longitude, degrees_east)\nDate (unitless)\nSa_ID (unitless)\nCore (unitless)\nsamp (unitless)\nDepth (centimeters (cm))\nErr (centimeters (cm))\nPorosity (cubic centimeters of porewater per cubic centimeters of total sediment (cm3pore water/cm3­total sediment))\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_959217_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_959217_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_959217_v1/index.htmlTable https://osprey.bco-dmo.org/dataset/959217 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_959217_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_959217_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_959217_v1
log in [Cascadia Margin seep DOC and associated geochemical data] - Porewater dissolved organic carbon and associated geochemical data for methane seeps in the Cascadia Margin: Astoria Canyon, Barkley Canyon, Hydrate Ridge, and Bullseye Vent (Collaborative Research: Investigating the source and flux of dissolved organic carbon released from methane seeps to the deep-ocean) These data include vertical profiles of concentrations and stable carbon isotope values of dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), 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, Barkley Canyon, Hydrate Ridge, and Bullseye Vent, along the Cascadia Margin, were sampled. These data were collected over two decades and across four cruises: PGC02-08 (CCGS John P. Tully, 2002), Hydrates 2004 Sea Trial (CCGS John P. Tully, 2004), AT50-14 (R/V Atlantis, 2023),  and AT50-29B (R/V Atlantis, 2024).\n\nThese 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.\n\ncdm_data_type = Other\nVARIABLES:\nRegion (unitless)\nCruise (unitless)\nSamplingDate (seconds since 1970-01-01T00:00:00Z)\nCoreID (unitless)\nSampleID (unitless)\nCoreType (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nWaterDepth_m (meters (m))\nMidDepth_cmbsf (centimeters below sea floor (cmbsf))\nporosity (unitless)\nSO4_mM (millimolar (mM))\nCH4_uM (micromolar (uM))\nDOC_uM (micromolar (uM))\nDOC_d13C_permil (per mille (‰))\nDIC_mM (millimolar (mM))\n...

(Collaborative Research: New approaches to study calcium carbonate dissolution on the sea floor and its impact on paleo-proxy interpretations) These data include solid phase measurements on sediment cores from the Cocos Ridge in the Eastern Equatorial Pacific. This cruise was aboard the R/V Sally Ride between 2021-11-20 and 2021-12-20. Instruments used were a multicorer, Liaison autosampler coupled to a Picarro cavity ring-down spectrometer, and Element Analyzer coupled to a Picarro cavity ring-down spectrometer. These data contributed to our understanding of the carbonate chemistry system in this region, particularly regarding carbonate dissolution in deep-sea sediments. Sijia Dong (Caltech) and Nick Rollins (USC) measured CaCO3 (PIC) and Organic_C (POC).\n\ncdm_data_type = Other\nVARIABLES:\nStation (unitless)\nDate (unitless)\nLatitude (degrees_north)\nlongitude (degrees_east)\nWater_Column_Depth (meters (m))\nSediment_Depth (centimeters (cm))\nPorosity (percent (%))\nCaCO3 (percent (%))\nOrganic_C (percent (%))\n https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_925132_v1/index.htmlTable https://www.bco-dmo.org/dataset/925132 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_925132_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_925132_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_925132_v1

The field experiment used in situ flow-through benthic chambers to measure oxygen consumption, as described in the methods paper Gadeken et al 2023. The chambers were deployed and retrieved in three ~24 hour deployments in a shallow subtidal area of Bon Secour Bay in Mobile Bay, AL, in August 2021.
