The successful candidate will conduct observational studies in a small watershed, and experimental studies quantifying the consequences of long-term warmer summer temperatures and deeper snow on ecosystem carbon cycling, and stream water DOC and DON fluxes. In addition, the individual will collaborate with others in the consortium using techniques to estimate the age of respired and transported carbon. The postdoctoral fellow will join a team (collaborators at University of California Santa Barbara and University of California Irvine) that has been conducting observational and long-term experiments in northwest Greenland since 2003. Familiarity with field photosynthesis systems (eg, LiCor 6200 or 6400), steam water chemistry techniques, data logging systems, and stable isotope techniques will be necessary.

The candidate will be expected to be in the field from late May to late August each year, and periodic winter campaigns will be necessary.

Excellent lodging and laboratory facilities are used by the team at the Thule Station for Arctic Research (TSTAR) during the field season.

During the academic year, the candidate will be housed in the Ecosystem Laboratory at UAA where the expanded UAA Stable Isotope Facility is located, along with the research laboratories of ten other UAA ecologists. The successful applicant will be expected to assist in supervising graduate and undergraduate students and to assist the project PIs with project management.

A PhD or previous postdoctoral research experience in ecosystem or physiological plant ecology, with a background in tundra ecosystem studies, is desired.
