Results of Experimental Additions of Organic Nitrogen on Soil Organic Matter Decomposition, Teller Road Site, Seward Peninsula, 2017 and 2018
Abstract
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. There are six *.csv data files and one *.pdf user guide.The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), was a research effort to reduce uncertainty in Earth System Models by developing a predictive understanding of carbon-rich Arctic ecosystems and feedbacks to climate. NGEE Arctic was supported by the Department of Energy's Office of Biological and Environmental Research. The NGEE Arctic project had two field research sites: 1) located within the Arctic polygonal tundra coastal regionmore »

NGEE Arctic was supported by the Department of Energy's Office of Biological and Environmental Research. The NGEE Arctic project had two field research sites: 1) located within the Arctic polygonal tundra coastal region on the Barrow Environmental Observatory (BEO) and the North Slope near Utqiagvik (Barrow), Alaska and 2) multiple areas on the discontinuous permafrost region of the Seward Peninsula north of Nome, Alaska. Through observations, experiments, and synthesis with existing datasets, NGEE Arctic provided an enhanced knowledge base for multi-scale modeling and contributed to improved process representation at global pan-Arctic scales within the Department of Energy's Earth system Model (the Energy Exascale Earth System Model, or E3SM), and specifically within the E3SM Land Model component (ELM).},
