Arctic Carbon: carbon dioxide and methane

The Arctic is warming at twice the rate of the global average and soils are rapidly warming. Luke Schiferl is leading our work to understand the drivers of long-term trends in CO2, while Ludda Ludwig is working on terrestrial and aquatic CO2 and CH4 fluxes around the Arctic.

 

Funded Projects

Luke Schiferl is using airborne observations from the NASA ABoVE program and NOAA tower observations in a long-term analysis of the CO2 signals from the Alaskan North Slope. Ludda Ludwig is investigating Hierarchical Scaling of Carbon Fluxes from Terrestrial-Aquatic Interfaces in the Arctic as part of her NASA FINESST fellowship in collaboration with the Woodwell Climate Research Center. Both Luke and Ludda will be working on our NSF AON project with Harvard University focused on making airborne eddy flux measurement of isotopic CO2 and CH4 over Arctic tundra. 

Recent Results

As part of the NASA Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) project and NASA Arctic Boreal Vulnerability Experiment (ABoVE), we calculated the emissions of methane and flux of carbon dioxide from Alaska. We also used NOAA data to examine the long-term trends in early winter CO2 respiration. Our work is continuing our research through a NSF Arctic Observing Network project with Harvard University.
