| Outline of Final Research Achievements |
Field survey on nitrification properties (ammonia oxidation potential and flora of ammonia oxidizer) of soils in a glacier foreland was conducted near Ny-Alesund, Svalbard in the European High Arctic. Immature soil in such the High Arctic showed nitrification. Relevant information utilizable for future study was derived, for example, a chronosequence is difficult to be applied such a glacier foreland due to perturbation by melting water and debris, and an open top chamber showed a passive warming effect with an 0.5 deg C increase in the mean soil temperature. Furthermore, talus soils under bird cliffs showed very high nitrification and denitrification potentials with positive temperature responses and in-situ nitrous oxide emissions.
