An event of permafrost degradation and recovery after a disturbance by 2002 Kougarok wildfire was discussed from long-term monitoring and permafrost core analysis on the central Seward Peninsula.

Significant methane oxidation activity was observed in incubations of flat-centered polygon transitional soil and permafrost layers, which also exhibited high levels of methane production activity under anoxic conditions.

Explicitly representing plant physiological root traits and improving the nutrient competition algorithm with the Equilibrium Chemistry Approximation removes known biases in CLM and ALM.

Soil moisture and thaw thickness strongly influence vegetation, and can serve as a proxy for vegetation greenness (and vice versa) during the growing season.

NGEE Arctic participates in University of Alaska Fairbanks Northwest Campus’ platform to discuss ongoing hydrology research efforts with the community.

An implicit time-stepping model for decomposition, nitrification, denitrification, and plant nutrient uptake was implemented in the Community Land Model (CLM), the land ecosystem component of a coupled Earth System Model.

Complex biogeochemical networks that include many biotic and abiotic processes can be limited by different substrates under different conditions during their temporal evolution.

Permafrost thaw and climate warming accelerates frozen soil organic carbon (SOC) degradation and emission of greenhouse gases, but what specific degradation pathways for labile SOC occur prior to CH4 and CO2 production are not well understood.

The NGEE Arctic website, to be released later in April, will have a new look and feel moving from an unsupported Drupal 6 into Drupal 7.
