| Summary: | This dataset provides the results of the experimental addition of glutamic acid on anaerobic organic matter decomposition as measured in the field and through laboratory methods. Field experiments were conducted during the summers of 2017 and 2018 at the NGEE Arctic Teller Road Site at mile marker 27 (TL_MM27) near Intensive Site 9 (TL_IS_9). At the field site, a solution of glutamate (13C- and 15N-labeled glutamate in 2017, unlabeled in 2018) was injected belowground and investigators observed the resulting changes in downslope porewater geochemistry and dissolved greenhouse gas concentrations. Soil collected near the site in 2017 was used in a laboratory column flow-through experiment with added glutamate. Results of porewater geochemistry, dissolved greenhouse gasses, and organic matter composition analyses for 2017 and 2018 experiments are provided. |
