Iron and Iron-Bound Phosphate Accumulate in Soils of Polygonal Tundra
Geochemical and spectroscopic characterization of active-layer soil indicate near-surface accumulation of iron oxides that sequester the nutrient phosphate.
NGEE Arctic Contributes to NOAA’s 2019 Arctic Report Card
NGEE Arctic contributed to the Arctic Report Card chapter on ’Tundra Greenness’ including changes in the cover of alder shrubs that impact local nutrient cycling.

Investigations of topographic control on thermokarst development and the ground thermal regime in ice wedge polygons using the Advanced Terrestrial Simulator
NGEE Arctic researchers found that rim height and trough depth in ice wedge polygons considerably influence the vulnerability of the underlying permafrost, shaping feedbacks which ultimately control topographic deformation and increased soil aeration in t
