Progress and Accomplishments
Numerical experiment suggest that reliable projections of air temperature and total snowfall may not be sufficient to understand permafrost degradation.
Multi-year field observations improve process representation in polygon hydrology models.
NGEE Arctic researchers use fusion of numerical models and data to estimate subsurface porosities of the polygonal tundra.
Research shows how individual species can disproportionately impact ecosystem carbon balance.
Ground-Based and UAV-Collected Snow Measurements Compared across a Watershed on the Seward Peninsula
Snow measurements collected with a UAV and ground-based data collection techniques show strong agreement.
Geochemical and spectroscopic characterization of active-layer soil indicate near-surface accumulation of iron oxides that sequester the nutrient phosphate.
Seasoned by the NGEE Arctic project, scientist gets tapped for a new opportunity.
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.
Numerous posters, oral, and organized sessions submitted to AGU continue to highlight science and science leadership by members of the NGEE Arctic project.
Scientists from across the country gather for their ninth annual NGEE Arctic All-Hands meeting to celebrate success and discuss progress and plans for the project.
