Ammonia Oxidation Property of Soils on the Glacier Foreland of Austre Broggerbreen, Svalbard: Response to Open-top Chamber Experiments.

ABSTRACT: Recent warming and glacier retreat in the Svalbard Archipelago, part of the Arctic cryosphere, have become increasingly evident. The present study investigated the foreland of Austre Brøggerbreen near Ny-Ålesund to clarify how soil nitrification responds to changing conditions. Two sites, exposed for different periods following glacier retreat, were compared. A manipulation experiment using open-top chambers (OTCs) and homogenized initial soil conditions was conducted to assess the effects of site differences, the OTC treatment, soil depth, and interannual variations on soil and nitrification properties. Although the OTC treatment slightly increased soil temperature and moisture, its overall effect on soil properties, ammonia oxidation potential (AOP), and microbial properties was negligib
