Advancing the predictive power of Earth system models through understanding
of the structure and function of Arctic terrestrial ecosystems
Progress & Accomplishments
Identifying polygonal ground in arctic regions using GLCM texture features for random forest classification
Image textural features and machine learning models can effectively identify broad regions of polygonal ground topography in the arctic using panchromatic imagery.
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.
