Abundance of two Pelagibacter ubique bacteriophage genotypes along a latitudinal transect in the North and South Atlantic Oceans
This study characterizes viral and bacterial dynamics along a latitudinal transect in the Atlantic Ocean from approximately 10N to 40S. Overall viral abundance decreased with depth, on average there were 1.64 ± 0.71 x107 virus like particles (VLPs) in surface waters, decreasing to an average of 6.50...
