Therefore, understanding what control bacterial abundance in the ocean is important. This study compares the bottom-up and top-down controls of bacteria along the Kuroshio Extension in order to further understand the processes involved. The Kuroshio Extension is the largest sink for anthropogenic CO2, which creates an interesting environment for bacterial populations. The data indicated an importance of grazers and viruses controlling bacterial abundance more so than nutrients.en-USMarine microbiologyCarbon cycle (Biogeochemistry) -- KuroshioOther
