Assessing Viral Abundance and Community Composition in Four Contrasting Regions of the Southern Ocean
: We explored how changes of viral abundance and community composition among four contrasting regions in the Southern Ocean relied on physicochemical and microbiological traits. During January–February 2015, we visited areas north and south of the South Orkney Islands (NSO and SSO) characterized by...
