Advancing the predictive power of Earth system models through understanding
of the structure and function of Arctic terrestrial ecosystems
Progress & Accomplishments
Katrina Bennett to assume Q5 co-leadership responsibilities
Opportunities emerge for leadership in the NGEE Arctic project and we welcome Katrina Bennett to her new co-lead responsibilities for permafrost hydrology.
Permafrost Thermal Conditions are Sensitive to Shifts in Snow Timing
Numerical experiment suggest that reliable projections of air temperature and total snowfall may not be sufficient to understand permafrost degradation.
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.
NGEE Arctic Continues to Have a Strong Presence at the American Geophysical Union (AGU) Meetings
Numerous posters, oral, and organized sessions submitted to AGU continue to highlight science and science leadership by members of the NGEE Arctic project.
