Arctic Carbon

The Arctic is warming at twice the rate of the global average and soils are rapidly warming. Current projects: Scaling carbon fluxes across the YK Delta 

Luke Schiferl is leading our work to understand the drivers of long-term trends in CO2, while Ludda Ludwig is working on CH4 emissions around the Arctic.

 

Funded Projects

Ludda Ludwig is investigating Hierarchical Scaling of Carbon Fluxes from Terrestrial-Aquatic Interfaces in the Arctic as part of her NASA FINESST fellowship.

As part of the NASA ABoVE program, aircraft measurements of carbon dioxide (CO2) and methane (CH4) were made over Alaska and northern Canada in Summer 2017 for the ArctiCAP project (PI Colm Sweeney, NOAA). Luke Schiferl is leading this analysis and including these data in a long-term analysis of the CO2 signals from the Alaskan North Slope. Margaret Powell (now pursuing a masters in Germany) lead our work on airborne methane data as part of her senior thesis at Harvard College. 

Recent Results

As part of the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) project, 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.
