Fate of Carbon in Soil Systems: Alaskan Landscapes
To understand the impacts of permafrost degradation (thaw) on ecosystem carbon and water cycling, which is critical to the management of habitats and fires on federal lands.Abstract
Formulates and tests scientific hypotheses to understand what key factors determine the fate of carbon in boreal terrestrial environments by examining the interaction of climate with soil drainage, fire disturbance, permafrost/active layer changes, and vegetation. To address the science needs of U.S. Carbon Cycle Science Program, an interagency partnership is dedicated to developing whole-system predictive capabilities for the global carbon cycle. Because boreal forests contain large carbon reserves that are highly susceptible to changes in climate, process studies and modeling efforts are needed to better understand the historic and modern interactions among climate, surface temperature and moisture, fire, and terrestrial carbon sequestration.
