Changes in viral and bacterial communities during the ice‐melting season in the coastal Arctic (Kongsfjorden, Ny‐Ålesund)
Summary Microbial communities in Arctic coastal waters experience dramatic changes in environmental conditions during the spring to summer transition period, potentially leading to major variations in the relationship between viral and prokaryotic communities. To document these variations, a number...

Summary Microbial communities in Arctic coastal waters experience dramatic changes in environmental conditions during the spring to summer transition period, potentially leading to major variations in the relationship between viral and prokaryotic communities.
