Paper led by collaborator Michael Carlson is now published in Nature Microbiology. Carlson measured viral abundances and active viral infection of cyanobacterial populations in the North Pacific over several years. Carlson identified a hotspot of cyanophage and virus-infected picocyanobacteria in the transition zone between the North Pacific Subtropical and Subpolar gyres, highlighting the impact of viruses on large-scale phytoplankton biogeography and biogeochemistry in distinct regions of the oceans. Another nice collaboration out of the SCOPE-Gradients Program!
