NGEE Arctic Completes its Fifth Successful Snow Campaign
In what was a long-awaited activity, a team from LANL, UAF, and ORNL successfully completed its fifth end-of-winter snow campaign at both the Teller 27 and Kougarok 64 field sites.
Talik Formation Observed Across Discontinuous Permafrost in Alaska
Observations at multiple field sites confirm widespread permafrost degradation with implications to thermokarst development, hydrology, and carbon cycle processes
DOE BER Environmental System Science Program PI Meeting, Safety Breakout
The NGEE Arctic project team represented our safety culture at a ‘Safety for field and work travel’ breakout session at the annual DOE BER ESS PI Meeting
High Nitrate Variability on an Alaskan Permafrost Hillslope Dominated by Alder Shrubs
Novel field investigation demonstrates how soil nitrate levels across an arctic landscape are influenced by the presence of nitrogen-fixing shrubs, local topography, and rain events
Sensor Arrays with Unprecedented Vertical and Lateral Resolution
Novel sensor arrays provide high-accuracy depth-resolved measurements of snow and soil temperature and soil deformation, and open the door for the deployment of dense sensor networks.
Quantifying pH Buffering Capacity in Acidic, Organic-Rich Arctic Soils
Soil pH buffering capacity correlates with soil water retention in organic-rich Arctic soils, providing a proxy to improve representation of pH buffering in biogeochemical models.
