Archaeal diversity and abundance within different layers of summer sea-ice and seawater from Prydz Bay, Antarctica
Fluorescence in-situ hybridization (FISH) and 16S rRNA gene clone library analyses were used to determine the abundance and diversity of archaea in Prydz Bay, Antarctica. Correlation analysis was also performed to assess links between physicochemical parameters and archaeal abundance and diversity w...
