Marine viruses in the Southern Ocean ANTXXIV-3 Cruise Feb - Apr 2008

Three transects were completed of the Greenwich Meridian, Weddell Sea and the Drake Passage to examine spatial variation in an area between -70.6 °S to -37.0 °S and 140 °E to -65.5 °E. Abundances of algae, bacteria and viruses were measured using flow cytometry and viral production was determined by an incubation based method.

A dilution method was also used to determine grazing and viral lysis of the algae and bacterial production was measured using radio labelled leucine incorporation.
