Abundance and distribution of planktonic Archaea and Bacteria in the waters west of the Antarctic Peninsula
Polyribonucleotide probes targeting planktonic archaeal (Group I and II) and bacterial rRNA revealed that Archaea comprised a significant fraction of total prokaryote cell abundance in the marine waters west of the Antarctic Peninsula. Determinations of Archaea and Bacteria cell abundances were made during two research cruises to the Palmer Long-Term Ecological Research region during the austra...
متن کاملSeasonal Succession of Free-Living Bacterial Communities in Coastal Waters of the Western Antarctic Peninsula
The marine ecosystem along the Western Antarctic Peninsula undergoes a dramatic seasonal transition every spring, from almost total darkness to almost continuous sunlight, resulting in a cascade of environmental changes, including phytoplankton blooms that support a highly productive food web. Despite having important implications for the movement of energy and materials through this ecosystem,...
متن کاملGlacial meltwater dynamics in coastal waters west of the Antarctic peninsula.
The annual advance and retreat of sea ice has been considered a major physical determinant of spatial and temporal changes in the structure of the Antarctic coastal marine ecosystem. However, the role of glacial meltwater on the hydrography of the Antarctic Peninsula ecosystem has been largely ignored, and the resulting biological effects have only been considered within a few kilometers from s...
متن کاملLeg 178 Antarctic Peninsula
Leg 178 will drill eight sites off the Pacific margin of the Antarctic Peninsula to provide a highresolution record of Antarctic continental climate over the past 6-10 m.y. and a direct check on the presumed glacio-eustatic origin of global sea-level change over the same period. Moreover, it is an essential preliminary to the more difficult task of extracting the complete Cenozoic record of Ant...
متن کاملViruses and Protists Induced-mortality of Prokaryotes around the Antarctic Peninsula during the Austral Summer
During the Austral summer 2009 we studied three areas surrounding the Antarctic Peninsula: the Bellingshausen Sea, the Bransfield Strait and the Weddell Sea. We aimed to investigate, whether viruses or protists were the main agents inducing prokaryotic mortality rates, and the sensitivity to temperature of prokaryotic heterotrophic production and mortality based on the activation energy (Ea) fo...
