NGEE Arctic Plant Traits: Vegetation Plot Locations, Ecotypes, and Photos, Kougarok Road Mile Marker 64, Seward Peninsula, Alaska, 2016
This dataset provides field site documentation for related datasets including GPS waypoints for intensive plots, reference points, vegetation plots, and soil temperature/moisture monitoring stations that were established in July 2016 at the Kougarok hill slope located at Kougarok Road, Mile Marker 64. At all intensive plots and reference points, photographs of the surrounding area were also taken using an Olympus Stylus TG-3 digital camera. Photographs were July 2nd through July 7th looking in each of the four cardinal directions. GPS waypoints were taken using a Garmin eTrek 10 handheld GPS and World Geodetic System 1984 (WGS-84). The error associated with the Garmin GPS coordinates was 9 foot or approximately 3 m. When marking waypoints, users waited until the instrument reached this error level before recording. Coordinate units are decimal degrees. This dataset is comprised of one comma-separated (*.csv) file containing GPS waypoints locating intensive plots, reference points, soil temperature/moisture monitoring stations, and vegetation plots. The dataset also contains one folder of photographs (*.jpg) taken at intensive stations, one folder of photographs (*.jpg) taken at reference points, and one User file (*.pdf).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 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).
