Abundance and distribution of planktonic Archaea and Bacteria in the waters west of the Antarctic Peninsula. Limnol. Oceanogr
Polyribonucleotide probes targeting planktonic archaeal (Group I and II) and bacterial rRNA revealed that Ar-chaea comprised a significant fraction of total prokaryote cell abundance in the marine waters west of the Antarctic Peninsula.
