Growing season trace gas and environmental measurements at an experimentally-warmed mesic tundra site
The data set was collected as an ongoing study at the Cape Bounty Arctic Watershed Observatory International Tundra Experiment (ITEX) site examining the environmental controls over trace gas respiration in High Arctic mesic tundra.

The data set was collected as an ongoing study at the Cape Bounty Arctic Watershed Observatory International Tundra Experiment (ITEX) site examining the environmental controls over trace gas respiration in High Arctic mesic tundra.

These data files contain trace gas concentrations and environmental measurements from an ITEX mesic tundra experiment. Snow fences were set up at two sites of each replicate to determine the effect of snow depth on soil respiration.
