Abstract

This dataset consists of measurements of vegetation harvested from Areas A to D of Intensive Site 1 at the Next-Generation Ecosystem Experiments (NGEE) Arctic site near Barrow, Alaska. The dataset includes i) values of leaf area index, biomass, carbon (C), nitrogen (N) and phosphorus (P) content of aboveground plant parts from 0.25 m x 0.25 m clip-plots at peak growing season and ii) fine-root biomass from 5.08-cm diameter soil cores taken throughout the active layer in the same location as the clip plots in late July-early August 2012, and iii) values of aboveground biomass and nitrogen (N) content measured from 0.1 m x 0.1 m clip-plots harvested at 2-week intervals throughout the 2013 growing season. This dataset includes five csv files and one pdf file.

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
Live material was separated by species and plant part, area of leaves was measured on a LiCor Area Meter, and then material was dried at 70 oC for 2-3 days and weighed. All plant material was ground (2601 Pica Blender Mill, Cianflone Scientific Instruments, Pittsburgh, PA, USA), and N and C contents were determined using a Model 4010 Elemental Combustion System (Costech Analytical Technologies, Valencia, CA, USA). Phosphorus concentrations in the plant tissues were analyzed in Kjedahl digests on a QuikChem 8500 analyzer (Lachat Instruments, Loveland, CO, USA) using Lachat Quikchem Method 13-115-01-1-B.
