Carbon Dioxide and Methane Emissions from a Temperate Salt Marsh Tidal Creek: Dataset

Coastal salt marshes store large amounts of carbon but the magnitude and patterns of greenhouse gas (GHG; i.e., carbon dioxide (CO₂) and methane (CH₄)) fluxes are unclear. Information about GHG fluxes from these ecosystems comes from studies of sediments or at the ecosystem-scale (eddy covariance) but fluxes from tidal creeks are unknown. <br>This dataset includes GHG concentrations in water, water quality, meteorology, sediment CO₂ efflux, ecosystem-scale GHG fluxes, and plant phenology; all at half-hour time-steps over one year.<br>This study was carried out in the St. Jones Reserve, a component of the Delaware National Estuarine Research Reserve in Dover, Delaware, U.S.A. The study site is part of the following networks:<br>- AmeriFlux (https://ameriflux.lbl.gov/sites/siteinfo/US-StJ) - Phenocam (https://phenocam.sr.unh.edu/webcam/sites/stjones/) <br>The GHG concentration and efflux sampling point was located at Aspen Landing within a microtidal (mean tide range of 1.5 m), mesohaline (typical salinity of 5-18 ppt) salt marsh (Delaware Department of Natural Resources and Environmental Control, 2006) tidal creek.<br>Main reference: Trifunovic, B., Vázquez‐Lule, A., Capooci, M., Seyfferth, A.
