Saltmarsh carbon and nitrogen cycling nutrient data in two northern Gulf of Mexico saltmarsh plants from 2017-2018 (NCEI Accession 0209238)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 03:35 AM | Dataset Last Updated: May 08, 2020 at 12:00 AM
This dataset contains salt marsh nutrient data to determine the biogeochemical impact of elevated nutrient loading on ecosystem carbon dynamics and nitrate reduction pathways (denitrification and dissimilatory nitrate reduction to ammonium (DNRA)) in plots dominated by either Juncus roemerianus or Spartina alterniflora that were colocated in a northern Gulf of Mexico salt marsh. The nutrients measured in this dataset include saltmarsh denitrification potential, anaerobic ammonium oxidation (anammox) potential, porewater nutrient concentrations, gross primary productivity, ecosystem respiration, and others. This data is available in CSV format.
