Alexandra Fiord Dry Tundra Ecosystem [Welker, J., J. Fahnestock]
The data set presented here represents growing season (late-1999, 2000 and 2001) values of net carbon dioxide exchange, photosynthesis, and respiration between the atmosphere and dry heath tundra. The site is located at Alexandra Fiord on the east-central side of Ellesmere Island, Nunavut, Canada at...
