Zusammenfassung: | The permafrost in the polar regions is vital for maintaining the status quo of the earth’s climate by limiting greenhouse gas emissions. The present study aims to investigate the seasonal variations and the influence of physicochemical parameters on the bacterial diversity and community structure of active layer permafrost (AL) around Ny-Ålesund, Svalbard. The AL soil samples were collected from four different geographical locations around Ny-Ålesund during the winter and summer seasons. The 16S rDNA amplicon sequencing was carried out to investigate the diversity and distribution profiles of bacterial communities among the collected AL samples. Physico-chemical parameters including soil pH, moisture content, total carbon (TC), total nitrogen (TN), and trace metals concentrations were measured. Bacterial phyla, Proteobacteria (15.4%–26%) and Chloroflexi (9.6%–22.5%) were predominantly distributed across both seasons. In the winter samples, Verrucomicrobiota (14.12%–23.39%) phylum, consisting of genera
