| Title | Diversity of bacterial communities in High Arctic snow and freshwater as revealed by pyrosequencing of 16S rRNA genes |
| Study Type | Metagenomics |
| Abstract |
The goal of this study was to explore questions about the bacterial diversity in different snow layers and an ice-covered freshwater lake in the High Arctic. Bacterial community structures in High Arctic snow and an ice covered freshwater lake were examined by pyrosequencing of 16S rDNA. The phylo .. [more]genetic composition of the microbial assemblages differed among snow layers and between snow and freshwater. The highest diversity was seen in snow. [less]

| Description |
Snow and freshwater were collected in Spring 2007 at Station Nord in North-eastern Greenland. Snow on the sea-ice was sampled in Dagmar Sund (81*36.58'N; 16* 42.83'W) between Station Nord and Prinsesse Dagmar Island, while the freshwater samples were taken from a small ice and snow covered lake abou .. [more]t two km south of the station (81*34.48'N ; 16* 37.46'W). The sampling depths in the snow were: top-snow (31-52 cm depth) middle-snow (75-90 cm depth) bottom-snow (96-112 cm depth) [less]
