Relevant Research and Experience (selected)

  • Assistant Research Professor, Water and Environmental Research Center, Institute of Northern Engineering and International Arctic Research Center, University of Alaska, Fairbanks. Research on methane in the Arctic, lakes, biogeochemistry, climate change, permafrost/thermokarst, carbon cycling, isotopes.
  • Research Program Manager, Oil Spill Recovery Institute in the Prince William Sound Science Center, Cordova, Alaska. Research program development and management of annual and strategic plans for a grant program focused on oil pollution issues in arctic and sub-arctic aquatic ecosystems. 2006-07.
  • UA Presidential International Polar Year Postdoctoral Fellowship: March 2007-2010. Research on carbon and nutrient cycling in northern lakes with particular attention to permafrost dynamics and thermokarst processes in the Arctic. Studies link to greenhouse gas emission estimates from modern lakes, lakes formed throughout the Holocene since the last deglaciation, and modeling of future lake dynamics as permafrost thaws in the Arctic. A variety of tools will be used in this work to assess methane and carbon dioxide emissions at different scales including ground-based chamber flux measurements, continuous measurements using eddy covariance, aircraft measurements, ground penetrating radar and resistivity measurements, and remote Synthetic Aperture Radar (SAR) analysis for extrapolation of emissions from lakes to regional and pan-arctic scales. Estimates of lake methane and carbon dioxide emissions based on this bottom-up scaling technique will be placed in the context of regional observations of atmospheric and ecosystem gas fluxes through collaborations in the Arctic Observing Network (AON). Outreach and education associated with this project form the Pan-Arctic Lake-Ice Methane Monitoring Network (PALIMMN and Student-PALIMMN), a network through which researchers, educators and community members participate in greenhouse gas monitoring by conducting simple surveys of gas bubbles in lake ice once each year in the autumns when the lakes freeze solid.
  • Arctic Observing Network: March 2007-2010. NSF 06-534 IPY: Collaborative Research on Carbon, Water, and Energy Balance of the Arctic Landscape at Flagship Observatories in a PanArctic Network.

Bret-Harte and Brian Barnes (UAF) and Gaius Shaver, John Hobbie and Edward Rastetter (MBL Woods Hole) to establish two observatories in the U.S. and Russia as part of the formation of a PanArctic network of observatories where coordinated measures of landscape-level carbon, water, and energy balance are carried out and results made available in a unified database. I coordinate science programs at the Northeast Science Station in Cherskii with those at Toolik Lake Field Station in Alaska, with particular research activities involving scaling techniques of CO2 and CH4 fluxes from thawing permafrost landscapes using ground and lake-ice surveys, chambers measurements, eddy covariance, aircraft measurements and remote sensing analyses.
