Progress and Accomplishments
Scientists around the world are working to simplify the vast array of plant species and forms in order to distill general features of plant function, structure, and strategy.
NGEE Arctic researchers are quantifying above and belowground variation in plant functional traits across environmental gradients to inform the representation of plant traits in terrestrial biosphere models.
A field research showed that evapotranspiration from mosses and open water was twice as high as that from lichens and bare ground, and that microtopographic variations in polygonal tundra explained most of this and other spatial variation
Controls on Fine-Scale Spatial and Temporal Variability of Plant Available Inorganic Nitrogen in a Polygonal Tundra Landscape
NGEE Arctic researchers documented strong relationship between soil moisture, inorganic N availability, and plant N content across the polygonal ground of the Barrow Environmental Observatory
Scientists working on the NGEE Arctic project provide evidence linking decadal patterns in arctic greening and browning with regional climate change and local permafrost-driven landscape heterogeneity, using newly developed decade time-scale remote
NGEE Arctic scientists from the University of Alaska Fairbanks and Lawrence Berkeley National Lab gave an overland tour of the Seward Peninsula to California’s Governor Jerry Brown to share hands-on climate change research in the Arctic.

We successfully integrated the Dynamic Vegetation, Dynamic Organic Soil, Terrestrial Ecosystem Model (DVM-DOS-TEM, University of Alaska Fairbanks) into the PEcAn framework to enable formal model uncertainty quantification (UQ), parameterization, and data-
We conducted our first NGEE-Arctic deployment of the multi-instrument Osprey heavy-lift octocopter at the three Seward Peninsula sites where we collected high-resolution visible imagery for structure from motion (SfM) 3-D plant and terrain surface heights
