Abstract
16S rDNA bacterial sequences (913) from the Arctic Ocean, Southern Ocean and Antarctic Iceland were studied to understand the bacterial distribution pat-tern. Through phylogenetic study, it was observed that some bacteria were common in both the Arctic Ocean and Antarctic Iceland. γ-Proteobacteria occu-pied 77.7% of the total bacterial population in the Antarctic Iceland, whereas in the Southern Ocean it was 72.5% and in the Arctic Ocean it was 50.9%. GC (Guanine + Cytosine) content of the bacteria in the Arctic Ocean and Antarctic Iceland region was 54.4% and 53.8% respectively. Bacterial diversity was calcu-lated using Shannon-Weiner index and was found to be highest in the Antarctic Iceland (1.6926).
