Chemical Indicators of Arctic Biological and Environmental Activities.
Two approaches were used to study the carbon cycling in a cold-dominated ecosystem at Barrow, Alaska. One involved a detailed analysis of the flow of CO2 between the atmosphere, soil and biota and the other concentrated on the internal carbon cycling in plants. A pilot study was also conducted which...
