| Research Abstract |
To obtain data of the dynamics of soil carbon cycle in the Arctic region where a rapid temperature rise would be expected by Global warming, the field investigation study was carried out at glacier retreat area in the Elsemir island (Canada) and Ny-Alesund (Spitsbergen island, Norwegian). We set up the investigation points belong to the transect line at each island considering with glacier retreat time and vegetation. At the each points, we measured soil respiration rates by chamber method, and collected soil gas and soil samples. The soil respiration rate and methane flux were changed by the difference of glacier retreat time, vegetation and permafrost layer depth.
