Seeking two highly motivated field assistants for a project 
that examines the effects of climate change on the carbon balance of west 
Greenland during the summer of 2012. Applicants will be working primarily 
with myself (Sean Cahoon, PhD Candidate, Penn State University) and loosely 
involved with other graduate students studying the ecology of climate change 
in the Arctic. 
Major goals of the project include: (1) monitoring above- and belowground 
plant productivity in response to experimental warming, (2) quantifying root 
respiration and leaf-level photosynthesis in several plant communities and 
(3) detecting the physiological and phenological drivers of ecosystem CO2 
exchange in the Arctic.  
A typical day in the field consists of conducting ecosystem or plant CO2 
flux measurements, collecting soil temperature and moisture data, stem and 
root growth measurements, vegetation reflectance, or data entry. 
Applicants must come prepared for many weeks of camping in the field and 
ready for all types of weather. The positions are not paid, however 
transportation from the US to Greenland and partial food expenses will be 
provided. I am looking for a 3-month commitment (mid May through mid 
August), however some flexibility is possible. 
Prior experience is not required, however qualified students must excel in 
their academic pursuits and exhibit a strong desire for a truly hands-on 
experience. 
Please send resumes or further questions to Sean Cahoon (sxc5218@psu.edu)
