Understanding the impacts of thermokarst lakes on permafrost stability, C cycling and greenhouse gas emissions
This research integrates field studies in a range of disciplines (geomorphology, geophysics, paleoecology, hydrology, limnology) with process modeling of permafrost thaw, lake... -
Arctic LTER Modeling
Modeling has played a major part in research at the Arctic LTER in studies of individual processes to studies of the biogeochemical linkages among carbon, nitrogen and water... -
Ecology, Soil Carbon, and Permafrost Experiments (ECOSCAPE)
This experiment is structured to understand fundamental biogeochemical feedbacks from permafrost thaw, and address the needs of the Integrated Ecosystem Model (IEM) project... -
Quantifying the Sources of Arctic Tundra-Respired CO2 Year-Round via Continuous in situ Sampling of 14CO2
The investigators will develop and deploy a novel system to continuously trap CO2 emitted from arctic tundra soils over several weeks for radiocarbon (14C) analysis. However,... -
Constraining the Relationship Between Vegetation Change and Net Carbon Sequestration in Arctic and Boreal Peatlands
Members of the Cyperaceae (sedges) inhabit diverse environments, spanning a wide range of moisture balance, pH, and nutrient availability. However, they are notoriously...
