Abstract

This dataset contains i) the results of field surveys of plant community composition and vegetation height made between 17th and 29th July 2012 in 48, 1 x 1 m plots located in areas A-D of Intensive Site 1 at the Next-Generation Ecosystem Experiments (NGEE) Arctic site near Utqiagvik (Barrow), Alaska and ii) results of a mapping exercise undertaken in August 2013 using two perpendicular transects across each polygon containing vegetation plots to determine the boundaries of vegetation communities described in 2012. This dataset includes six csv files, three pdf files, and a zipped folder of vegetation photos. 

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).

Methodology
Plant community composition was determined in 48, 1 x 1 m permanent plots between 17th July and 29th July 2012. Aerial percentage cover of all vascular, bryophyte and lichen species in each plot was estimated. The canopy was assumed to have two layers (i.e. sum of vascular plant species coverage 100 percent sum of moss/lichen coverage and bare ground 100 percent). Vegetation heights (dominant species and whole plant community) were measured during the plant community survey. Measurements were made using a steel ruler, considering zero to be the top of the moss layer and measuring without disturbing the canopy. Temporary transects were installed on all polygons containing vegetation plots on 19th August 2013, and surveyed using differential GPS. Communities boundaries along the transects were recorded using a measuring tape.
