Tracking Nitrogen in Arctic Plants
Prevailing nutrient uptake models do not fit Arctic plants. Scientists test a new option that overcomes older models’ shortcomings.
Root Traits Explain Nitrogen Uptake in Arctic Tundra; Colleen Iversen
Root traits and nutrient competition approach explain NGEE-Arctic observations
Defrosting the World’s Freezer: Thawing Permafrost
Snowy peaks rise up in one direction; boggy tundra spreads across the other. Fuzzy heads of long-stemmed plants sway in the wind, interspersed with bog blueberries.
Director's Early Scientific Career Achievement Award: Haruko Wainwright
For pioneering zonation-based estimation methodologies, with a focus on novel approaches that use geophysical data and their application to DOE challenges in environmental remediation, carbon cycle, and water resources.
Scientists Measure Pulse of CO2 Emissions During Spring Thaw in the Arctic
Findings by Berkeley Lab researchers mean the Arctic may be even less of a carbon sink than previously thought
Aquatic Plants May Accelerate Arctic Methane Emissions
About two thirds of the gas produced by a study area near Barrow, Alaska, came from increasingly abundant greenery covering only 5% of the landscape, researchers estimate.
Tennessee: Connected to the Arctic through Service & Science
Tennessee has a long history as the “Volunteer State” — so known because our citizens volunteered their lives in support of the War of 1812 at the Battle of New Orleans, and Texan independence in 1836 at the Alamo/
ORNL researchers contribute to State Department's Arctic blog
ORNL's Peter Thornton, Stan Wullschleger and Kate Evans have written an entry for the State Department's "Our Arctic Nation" blog on Medium.com. The blog, run by the Arctic Council of the State Department's Office of Oceans and Polar Affairs, invites ind
Funding Effective Interdisciplinary Collaborations: NGEE-Arctic as a Case Study—IARPC Collaborations Webinar Series
The Next Generation Ecosystems Experiments (NGEE-Arctic) is a 10-year Department of Energy (DOE)-supported project whose mission is to improve mathematical models that predict climate through advance understanding of the physical, chemical,
Drying Arctic Soils Could Accelerate Greenhouse Gas Emissions
A new study published in Nature Climate Change indicates soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands.
